Too Much Light While Sleeping , Could Be Hurting Your Health.
CNN reports that a study suggests sleeping while surrounded
by dim lighting could cause a rise in blood sugar and
increase heart rates in young and healthy people.
The study reportedly analyzed 20 healthy participants in their 20s, tracking their sleep for two nights in a sleep lab.
Researchers say on night one, the room
in which participants slept was so dark, "you wouldn't be able to see much, if anything, when your eyes were open.".
We recorded their breathing, their heart rate, their EKG,
and we also drew blood from them to measure melatonin levels while they were sleeping. , Dr. Phyllis Zee, director of the Center for Circadian
Sleep Medicine, Northwestern University, via CNN.
On night two of the study, some participants stayed in the dark, while others slept under
dim light equal to "a very, very dark, cloudy day or street lights coming in through a window.".
The study found that even such
minimal amounts of light were
negatively affecting participants, .
creating deficits in slow-wave
and rapid eye movement sleep.
Researchers say the light levels
on night two did not affect
melatonin levels in participants.
though their heart rates rose, insulin resistance increased and their nervous systems had fallen out of balance.
Experts say for the healthiest sleep,
turn off the lights and start using a comfortable sleep mask.

I think the strength of the evidence is that you should clearly pay attention to
the light in your bedroom. , Dr. Phyllis Zee, director of the Center for Circadian
