Summary
A study has shown that sleeping in a room with too much light energy, even in complete darkness or dim-lit areas, causes an increase in nighttime heart rate and a decrease in heart rate variability. This light exposure causes disruptions in the sympathetic arm of the autonomic nervous system, which can ultimately impact metabolism even outside of sleep.
