Don't Stay Indoors All Day
A good portion of our global workforce spends 90 percent of each day indoors, which essentially puts workers in a state of "light deficiency," and it negatively impacts our sleep cycle.
Instead:
Get outside, preferably earlier in the day, and for as long as you can.
Why?
We need more intense light to reset our circadian rhythm, which helps us sleep. Some sleep experts recommend being outside as much as two hours a day, but even going outside for 30 to 60 minutes during the day – say over a lunch break or during a walking meeting outdoors, will provide roughly 80 percent of what you need to "anchor" your circadian rhythm, according to Dan Pardi, a researcher with the Psychiatry and Behavioral Sciences Department at Stanford, and the Departments of Neurology and Endocrinology at Leiden University in the Netherlands.
