NEW YORK (WLNY) — For many, going to bed with a night light or leaving the television on during sleep is a routine practice, but the light from these devices can affect sleep, TV 10-55’s Katie McGee reports.
TVs can cause significant sleep disruption, and even when they are off, lights from control boxes and alarm clocks can cause problems.
“Light at night, even low levels of light, might actually suppress the secretion of melatonin,” said Dr. Ulysses Magalang, a sleep expert at Ohio State University Wexner Medical Center.
Lower levels of melatonin have been linked to depression.
Researchers say that light at night is still a relatively new problem for humans and thanks to the constant use of electronics, it has gotten much worse in the last decade alone.
