Why is morning sunlight important?

Sources:

Morning sunlight is crucial for setting circadian rhythms, promoting wakefulness, and ensuring a healthy pulse of the hormone cortisol early in the day. This pulse is important for a healthy immune system and should occur once every 24 hours, timed primarily by light exposure to the eyes. It also suppresses any residual melatonin, the hormone that induces sleepiness, and helps to trigger the metabolism 1 2.

Bright morning sunlight sets a timer for falling asleep approximately 16 hours later, contributing significantly to sleep quality. Witnessing sunlight in the morning can enhance mood, alertness, and even metabolism, potentially due to its effect on sleep 3 4. It's recommended to get morning sunlight exposure every day if possible, or double the duration of sunlight viewing the following day if a day is missed 2.

Morning Sunlight

Andrew explains the importance of getting morning sunlight to set your circadian rhythms and promote wakefulness. He emphasizes that the short pulse of cortisol that comes with morning sunlight is healthy and promotes a healthy immune system. He also gives tips on how to safely get sunlight exposure and mentions that this protocol applies to animals as well.

If morning sunlight is not available, turning on artificial lights can be a temporary measure, but once the sun rises, outdoor sunlight becomes essential due to its intensity and particular wavelengths, which artificial lights typically can't match 5. Additionally, getting sunlight later in the day can protect against the effects of artificial light at night 6.

Morning sunlight also impacts animals, as they have a natural inclination to seek out sunlight at the correct times, unlike humans who often need to be reminded about the importance of this practice 7. The importance of morning sunlight has been demonstrated in studies, showing that consistent exposure can adjust sleep patterns 7.

In summary, morning sunlight is essential for syncing our internal clocks, supporting our immune function, and preparing our bodies for sleep later in the day. It is a simple and cost-effective way to improve mental and physical health.
