Does sunlight therapy really improve sleep? A study published in Sleep Medicine Reviews found that light therapy can improve a variety of sleep problems.
Among them, the effect on physiological clock disorders (e.g. jet lag, night owls) was moderate, and the effect on insomniacs was even better, and it was also mildly helpful for sleep disorders related to Alzheimer’s disease and dementia. In addition, it is more effective for women.
If you want to sleep well at night, go out and get more sunlight during the day.
