That is a part of a sequence of brief episodes that try to offer a Feynman-type abstract of my understanding of a subject, in an actionable method, and in lower than half-hour. That is, in fact, as with each podcast, not medical recommendation. I’m not a physician, and I don’t play one on the web. So that is for instructional functions solely. I’m only a mother who cares very deeply in regards to the future well being of all of our youngsters, and the way forward for well being in our nation, and who spends method an excessive amount of time studying medical journals.
Additionally a reminder, we’re every our personal main well being care supplier, as you’re most likely bored with me saying by now. However whereas we are able to work with nice practitioners to assist enhance our well being, on the finish of the day, the accountability and the inputs, and the accountability for these inputs lie inside every of us.

You too can be a part of my publication for a weekly roundup of beneficial studying, articles, suggestions, and extra. And that’s discovered at wellnessmama.com/publication.
Now, on to the subject of this podcast, all about morning daylight, which you could have most likely heard me point out at the very least a number of instances within the historical past of this podcast. And I really like that this has develop into such a well-liked matter, with even a few of the largest podcasters, like Dr. Andrew Huberman, speaking about this fairly often. I additionally personally love Dr. Amy Shah’s latest suggestion on this podcast, the easy rule of “sky earlier than screens” within the morning.
On this episode, I’ll talk about the science of why morning daylight is helpful, how a lot we really want, what to do if you happen to get up earlier than the solar or do shift work. And what to do with outside gentle is actually not an possibility within the morning. As an example, if you happen to stay someplace the place there may be solely a few hours of daylight a day.
Basically, the recommendation to get morning daylight is among the only a few items of well being recommendation that I feel is universally useful. And I’ve beneficial this for over a decade as a result of not solely does it have profound advantages, however it’s a no value behavior that really anybody can do. And on a private stage, this is among the few issues that I attempt to do each single day, and I think about a non-negotiable. You’ve most likely heard me say I don’t do something each single day. And getting morning daylight and telling my youngsters I really like them are most likely a few the one exceptions to that rule. I think about morning daylight a foundational a part of well being that needs to be dialed in earlier than making an attempt something costlier or sophisticated, like dietary supplements or bio hacks. As a result of as you’ll perceive in a minute, this actually is a foundational and pivotal a part of well being for a lot of causes.
So, why morning daylight? Let’s have a look at a few of the science. I really discover it somewhat humorous that we have to flip to analysis to persuade us of one thing that people have doubtless performed naturally for the whole thing of our historical past. However the research taking a look at morning daylight shed some gentle, pun meant, on some fascinating facets of circadian biology. So let’s have a look at it. After we are uncovered to pure gentle within the morning, as quickly as potential after waking, it’s useful for a lot of causes, together with, to start with, that this indicators the pituitary gland to launch hormones. Vibrant morning gentle indicators the physique to suppress melatonin, which we wish whereas we’re sleeping, and improve cortisol manufacturing, which is sweet for us in wholesome quantities. And there needs to be a pure rise of cortisol within the morning, although many individuals, this sample could be a little skewed. And this morning gentle additionally helps us to supply dopamine and serotonin.
However the advantages prolong past simply that. You’ve most likely heard of your circadian clock or your physique’s grasp clock, that’s positioned in a area of the mind referred to as the suprachiasmatic nucleus. And this grasp clock is important to the well being and performance of our physique and our brains. And it’s concerned in how we sleep, our focus throughout the day, our power throughout the day, hormone perform, and a lot extra. In actual fact, 80% of the genes in our our bodies, and each organ within the physique, runs on a particular 24-hour repeating cycle on the path of this grasp clock. So merely, this clock is liable for sustaining the timing of our cells’ most vital life processes to maintain our our bodies functioning optimally. So mainly, if we wish to be wholesome and pleased, and have a well-functioning mind and help our metabolism, help our physique, and scale back threat of continual illness, most cancers, diabetes, and sleep points, we have to take note of and have a robust and constant circadian 24-hour rhythm. We’ll discuss a few of the different components that come into this in a minute. However gentle is a extremely large needle mover relating to this 24-hour rhythm.
Now, most of the research look particularly at the advantages of morning daylight on issues like sleep, temper, and hormone perform. There’s a 2008 examine that said, “The melatonin rhythm section development attributable to publicity to brilliant morning gentle has been efficient towards insomnia, premenstrual syndrome, and seasonal affective dysfunction or SAD. The melatonin precursor serotonin can also be affected by publicity to sunlight.” And this is the reason this examine and lots of research level to morning gentle publicity as a extremely good needle mover for sleep, focus, and temper all through the day. And I discussed there are different triggers as nicely. Gentle, temperature, and meals timing are three large components relating to sleep high quality. And light-weight, particularly morning gentle, appears to be one of many largest needle movers for sleep high quality and temper, particularly, as a result of it impacts the physique’s grasp clock so strongly. And in line with Dr. Huberman, viewing daylight within the morning could cause round a 50% improve in circulating cortisol, epinephrine, and dopamine. And within the morning, these leverage wholesome will increase in power, immune system perform, and temper.
So, basically, getting that little little bit of daylight publicity within the morning, can lead you to really feel happier, extra productive, and extra awake throughout the day, in addition to to sleep higher at evening. And we’ll get into the specifics of how a lot we have to begin that cascade. However this morning daylight additionally begins the clock for melatonin manufacturing at evening, which is among the causes that we wish to do that as quickly as potential after waking, as a result of that helps once more, suppress melatonin manufacturing that’s purported to occur in a single day, assist improve cortisol, which we wish to rise within the morning. And it begins that timer for after we’re going to begin making melatonin once more at evening to sleep nicely. A really oversimplified method to consider this, the sooner within the day and the extra daylight you’re uncovered to throughout the day, the higher your physique can produce melatonin at evening. And intuitively, that is additionally the rationale you wish to keep away from brilliant gentle and overhead gentle after sundown. However extra on that in a minute.
This morning daylight publicity additionally triggers the primary dopamine launch of the day. And as a result of this, morning daylight is a fairly straightforward behavior to combine, as a result of there’s a pure dopamine launch. So you’re going to get a optimistic suggestions loop out of your physique for doing it. And it’s a small behavior, since not a lot time is required. And we talked earlier than about behavior stacking. I’ve talked about this in a earlier episode, however you should use this to assist combine the behavior of morning daylight.
So, for instance, whereas I personally desire to get protein earlier than caffeine, if morning espresso is a dependable behavior for you, simply behavior stack and make the easy change to drink your espresso outdoors, and then you definitely’ve built-in the behavior of morning gentle. Or if like me, you wish to do protein earlier than caffeine, eat or drink some protein earlier than your espresso, and do each outdoors within the morning. However again to the science for a minute. Morning daylight additionally has an impact on serotonin. And we all know that publicity to full spectrum daylight within the morning indicators the physique to supply serotonin, which has been talked lots about up to now few years due to the psychological well being implications.
And so this not solely helps in a while with nighttime sleep, but it surely improves temper all through the day. And that is really why brilliant lights are beneficial as normal therapy for seasonal despair and seasonal affective dysfunction. As a result of outside gentle, even on a cloudy day, delivers significantly extra lux than indoor gentle. And for individuals who ask, I’ve heard this query on social media rather a lot. Even on wet winter days, there’s much more gentle outdoors. And though it might look darkish outdoors, you’ll nonetheless get a lot increased lux ranges of 1000 or extra, which is way larger than any inside gentle will produce. Apart from gentle particularly designed to supply a extra intense lux of sunshine. On a sunny summer time day, that morning daylight can ship gentle that’s as much as 1000 instances brighter than indoor gentle. So they don’t seem to be the identical factor. Getting brilliant gentle publicity indoors will not be going to be the identical as getting morning daylight. And in case you are a shift employee, which we’ll discuss in a minute, or really don’t have entry to outside gentle, there are some issues you are able to do that aren’t nearly as good, however they’re going to be higher than simply regular indoor gentle.
However as I stated, gentle is an important signaling mechanism for the physique. A few of the daylight that enters our physique on this morning time interval reaches the hypothalamus, which is concerned in regulating many of the features, life sustaining, particularly, features, in our physique. And that additionally provoke and direct our response to emphasize. And you may learn, I’ll hyperlink within the present notes, referred to as “Gentle Medication Of The Future,” by Jacob Lieberman, for a extra concerned clarification on that. One other examine checked out morning gentle publicity in relation to physique weight, and located that those that received morning daylight reliably weighed much less. And this was a dose-dependent and time-dependent response.
So from that examine, even after controlling for all non-light publicity components, together with meals consumption, sleep exercise, the affect of morning gentle on weight was appreciable. It accounted for roughly 20% of the themes’ BMIs. That means, these with earlier gentle publicity weighed much less, separate of all different components. And the outcomes of this examine exhibit that the timing of even reasonable depth outside gentle publicity is independently related to BMI or physique mass index. Which I’ve talked about earlier than is an imperfect measure, however it’s a dependable one in so far as basic tendencies.
So particularly, from that examine, having nearly all of the typical day by day gentle publicity above 500 lux earlier within the day, was related to a decrease BMI. Or in sensible phrases, basically, for each hour later, that daylight publicity was delayed within the day, there was a 1.28 unit improve in BMI. So this isn’t an insubstantial distinction. This most likely speaks to all the hormone issues we’ve already talked about. However in case you are making an attempt to get leaner, this may be an easy no value factor so as to add to your toolkit to essentially begin to transfer that needle hopefully.
And anytime I point out morning gentle, numerous questions come up on how a lot do we want, the way to do it. The estimates vary somewhat bit and the way a lot we want, particularly based mostly on what a part of the world you reside in, what time of yr it’s, if it’s cloudy or not. On the very low finish, it could possibly be as little as two minutes in very brilliant climates. However I all the time personally intention for at the very least 5, to form of hit that minimal efficient dose. And as much as half an hour on the whole goes to type of optimize the consequences. However on the whole, the extra time outdoors, the higher. However that minimal efficient dose is so vital. If it’s a brand new behavior for you, possibly intention for under 5 to 10 minutes, however simply attempt to make it a dependable behavior.
Now, a word right here on the the way to. This publicity does must be totally open air and never by means of a window. Although, in principle, you may be below a porch, so long as you’re outdoors and uncovered to the sunshine. However as Huberman defined in a latest podcast, whenever you have a look at daylight by means of a window, it’s 50, 5-0, instances much less efficient than if the window had been to be open. Largely as a result of the window filters out numerous wavelengths of blue gentle which are really important for exciting the eyes and beginning this wake-up sign that we talked about. And this is the reason brilliant gentle all all through the early a part of the day is vital.
Ideally, we wish as a lot outside time as potential. I do know that’s typically troublesome in our fashionable world. However if you happen to can completely get that very first thing within the morning. And in case you are indoors the remainder of the morning, you possibly can think about using brilliant overhead lighting, or perhaps a 10,000-lux gentle field, which I’ve. And a word right here, if you wish to get actually tactical with this. As a substitute of simply having it in your desk or at eye stage, if potential, have it above your head. And I’ll clarify somewhat bit extra about that in a minute. However mainly, the concept is, these sorts of brilliant gentle in nature come from above us, not at eye stage. And I’ll really give some particular suggestions for optimizing the sunshine in your house in only a minute. However if you happen to’re going to spend money on a lightweight field, of which there are some comparatively cheap ones I’ll hyperlink to within the present notes, if potential, have that gentle coming from overhead when you’re working within the morning.
Now, as I stated, this explicit podcast is primarily targeted on morning daylight, and its want to achieve the eyes to attain all of those advantages. It’s on no account the one daylight we have to perform optimally, however simply the one we’re speaking about right this moment. Very briefly, noon daylight serves its personal objective. And whereas morning daylight, it’s vital for it to hit our eyes, noon daylight ought to ideally attain as a lot of our pores and skin as potential. And I’ll do a complete separate episode on this. However the advantages, in fact, of noon solar additionally then prolong to vitamin D publicity, in addition to potential improve of vital hormones like testosterone, and estrogen, and temper enhancing advantages as nicely.
However for individuals who are curious, this morning daylight, whereas it’s all the time nice to get daylight publicity on the pores and skin, the actually vital mechanism is that your eyes are uncovered to the sunshine. Whereas noon solar, the pores and skin facet is extra useful, since you’re additionally not going to make as a lot vitamin D from morning gentle publicity as you’re noon solar.
And in the identical method… It is a matter for one more podcast as nicely. However for all the explanations brilliant gentle is nice early within the day, it’s counterproductive within the late afternoon, or night and past, as a result of it does the alternative of what you need at the moment. So it suppresses melatonin manufacturing. And we wish melatonin manufacturing to go up after it will get darkish, and as we get near bedtime. And if we get brilliant gentle publicity at evening, this will then have an effect on temper and impair sleep, however have an effect on our temper even the following day. So Huberman, I consider, has a suggestion to utterly keep away from all brilliant gentle from 10 p.m. to 4 a.m., because of this. And I personally attempt to decrease brilliant gentle and even indoor gentle publicity as a lot as potential after sundown.
Now, I do know this query will come up. What about shift employees? And this can be a nuanced scenario that does rely lots on how a lot you’re various from regular circadian rhythm, and from the traditional life cycles. Analysis means that shift work is related to insomnia, decrease efficiency, and an elevated threat of office accidents, heart problems, metabolic syndrome, diabetes, autoimmune hypothyroidism, and particular sorts of most cancers. Which really is smart after we perceive all the issues I’ve already talked about, and the way this indicators our grasp clock.
So, this clearly isn’t ultimate, but all of us profit, and I’m extraordinarily grateful for the individuals who do that vital work. There have been wonderful individuals doing shift work which have been there once I’ve had infants in the course of the evening or had medical emergencies in the course of the evening. And I’m so grateful that these individuals are prepared to do this. There are some issues that shift employees can do this assist form of mitigate the issues with not lining up with the traditional gentle cycles of the planet.
So anytime somebody must adapt the sleep and lightweight cycle that isn’t according to the pure cycles of the solar, it does current some challenges. There are some issues you are able to do to make it simpler. And based mostly on what I’ve already stated, you possibly can most likely guess most of them. However it might be issues like utilizing brilliant gentle, even these synthetic 10,000 lux or increased types of gentle, if wanted, on the a part of the day that’s the morning for the particular person doing the shift work. So the primary a part of the day for this particular person. Additionally, it might be crucial to maintain sleep surroundings utterly darkish, even when this particular person is sleeping throughout the day. And you should use issues like blackout curtains, and so on., to maintain the sleep surroundings as completely darkish as potential.
There’s additionally components like syncing up gentle and meals as a lot as potential to the schedule that the particular person must comply with. And maybe most troublesome, staying on the routine as a lot as potential. Although it’s not ultimate to be on a unique gentle cycle, it’s the switching forwards and backwards that may be essentially the most troublesome if it’s performed all through the week, and type of sign essentially the most chaos within the physique. In order a reminder, utilizing brighter gentle within the first half of shift work, after which if potential, dimming gentle because it will get near sleep time will be useful. And naturally, if somebody’s working in a hospital surroundings, this particular person might haven’t any management over the lighting. That’s clearly a problem. However in that case, conserving meals timing and different components lined up as a lot as potential, after which conserving the sleep surroundings very, very darkish.
I additionally wish to discuss some circadian-friendly residence lighting strategies, in gentle of understanding how these gentle cues work. As a result of I’ve hopefully established that outside gentle is helpful, particularly within the morning, and particularly as quickly as potential after waking up or after the solar rises. Extra time open air appears typically useful. And engaging work just like the Tenting Examine, reveals that even only a few days away from synthetic lighting can drastically shift and enhance our circadian cycle. Which is smart after we perceive how a lot gentle regulates the grasp clock. However since many people do should spend time indoors as a part of our day by day lives, there are some issues we are able to do to assist optimize the indoor surroundings after we are inside, particularly. We are able to be sure that our sleep environments are freed from all synthetic gentle. I personally use blackout curtains in my room, and I don’t have any gadgets or something that has even a small gentle in my sleep surroundings. We are able to additionally optimize different components of the home for non-sleep instances. And this may be guided by taking a look at what occurs naturally open air, after which mimicking it as a lot as potential indoors.
So as an illustration, brilliant outside gentle and blue gentle hues, most frequently in nature come from above, because the solar is highest within the sky when it’s its brightest. Dawn and sundown, the solar is decrease and it has extra purple and orange hues. So, to imitate this in my home, I exploit brilliant daylight full spectrum bulbs within the ceiling lighting and overhead lighting. And I discussed I’ve a ten,000 lux gentle that I hold above my desk as an alternative of getting it at eye stage. I even have many lamps in my home which are at eye stage or beneath. And these have low or no blue gentle bulbs. And these are what go on in my residence after sundown. I’ll hyperlink to a few of the particular ones I exploit within the present notes. However you simply wish to discover for the ceiling, some actually brilliant excessive spectrum lighting. After which for lamps at eye stage, the decrease blue gentle dimmer lights. And if this can be a lot to recollect, you possibly can put timers on the lamps in order that they go on and off on the proper time. And that’s additionally the cue to show off the overhead lighting. And at my home, this occurs at sundown. It’s not ultimate, but when you’re going to be taking a look at synthetic gentle at evening, this could be a time you may use blue gentle blocking or decreasing glasses, if you happen to’re gonna be taking a look at screens. Although, in an ideal world, we’d simply keep away from synthetic gentle and screens after darkish.
Now, a number of caveats and reminders. We wish to get morning gentle and it should be open air, as a result of by means of a window is way much less intense, and it’ll take a lot, for much longer to have the identical profit. That morning gentle is as a lot as 50 instances brighter. If potential, you wish to keep away from glasses. So if you happen to put on glasses, if potential, take them off even for only a couple minutes in that morning interval when you’re outdoors. However actually keep away from sun shades throughout this section, or trying by means of a window. And this brilliant gentle publicity is helpful even on cloudy or gloomy days.
I do know I’ll get lots of people asking, so if you happen to get up earlier than dawn, simply make it a degree to get daylight as quickly as potential after dawn. It’s a subject for one more episode, like I stated. Noon gentle can also be crucial for different causes. And viewing the sundown has its personal set of advantages as nicely. However this episode is primarily targeted on the significance of morning daylight. Additionally, as I stated, this early morning gentle will not be about vitamin D. That can also be a subject for its personal episode. Early morning isn’t really one of the best time to get vitamin D. However as I’ve established, this morning daylight publicity is vital for all the opposite causes we’ve mentioned. As a result of morning gentle hitting massive areas of pores and skin can nonetheless be useful. However an important factor is for the eyes to get the publicity.
Now, this doesn’t imply we have to look straight on the solar. And actually, we shouldn’t. We simply wish to be open air with out home windows or glasses in the way in which of those receptors in our eyes. I hope that the knowledge on this podcast has additionally pointed to a basic development of spending extra time open air, and the significance of pure gentle, and the way good that’s for us, on the whole. My youngsters are literally doing, proper now, a problem referred to as 1000 hours outdoors. And they’re monitoring this on a paper on our fridge. They’re making an attempt to get 1000 hours in a single yr, which equals roughly a number of hours a day.
And the identical issues that make morning daylight useful are the explanations to keep away from brilliant gentle and blue gentle at evening. Once more, one other episode on that. However I hope that this brief episode has satisfied you that including morning gentle publicity to your routine, if you happen to aren’t already doing this, is among the best and probably most profound issues you are able to do on your well being, your temper, your sleep, and your stress.
I really like discovering habits which are a comparatively straightforward factor to implement, and that may have very noticeable and compounding results over time. And I feel gentle is a crucial place to start this dialogue. As a reminder, intention for at the very least 5 minutes as quickly as potential, after waking or after the sunrises, not by means of a window and never whereas carrying glasses or sun shades.
And I’m curious, is that this a behavior you have already got? If not, will you attempt it and attempt to make it a behavior? I might love to listen to your suggestions within the present notes at wellnessmama.fm, or you possibly can message me straight on Instagram.
