How You Can Train Your Brain To Be Motivated | Dr. Andrew Huberman
"What they found is that melatonin rhythms, cortisol rhythms, which can be a healthy thing. We all have cortisol. It protects us, energizes us. Dopamine, epinephrine, all these rhythms of the body could be reinstated to their proper timing by waking up and seeing the sun and going to sleep not too long after sunset, depending on time of year, for 2 nights and 2 mornings. Wow. And this lasted at least 2 weeks, even though people were getting artificial light."
Huberman recommends getting bright outdoor light soon after waking and says evidence supports it for mood, sleep and metabolic health. As an example, he cites a University of Colorado study in which college students camping for two nights and mornings reportedly re-aligned melatonin and cortisol timing, with effects persisting for at least two weeks after returning to artificial light.
