Getting insufficient sunlight exposure during the day may lead to problems sleeping at night, according to a new study which recommends that people go out in the morning sun, even if it is for a “little while.”
The research, published last week in the Journal of Pineal Research, used wrist monitors to follow the sleep and light exposure patterns of over 500 undergraduate students at the University of Washington (UW) in the US from 2015 to 2018.
