Should you close the blinds while you sleep?

Is your room dark enough when you go to bed at night? Research suggests that minimizing light while sleeping is protective for health.

Study Summary

A recent study found that a single night of sleep with exposure to moderate lighting can prevent proper glucose and cardiovascular regulation, both of which increase the risk for heart disease and diabetes.

A body of research supports the idea that improper light exposure is disruptive to the circadian rhythm, melatonin levels and negatively impacts health.

The Hearty Take

At Hearty, we recommend that you minimize light while sleeping. Close the blinds and turn off the lights before bed to keep your circadian rhythm optimized.
