Sleeping With Even a Little Light Isn’t Good for Your Health

Sleeping With Even a Little Light Isn’t Good for Your Health

A team of researchers led by Dr. Phyllis Zee at Northwestern University studied 20 people to see how 100 lux of artificial light affected half of the healthy adults while they slept.

The 10 people that were exposed to artificial light while they slept had elevated heart rates during the night and had increased insulin resistance in the morning.

The second finding means that those people had more trouble than the others getting their blood sugar into what would be considered a normal range.

A lot of what happens while we sleep is still a mystery but this study seems to be a good start to figuring out how light affects us when we’re getting rest.
