Sleep in Total Darkness

Even the smallest amount of visible light can interfere with your sleep. You can help block out all light either by using blackout curtains to your bedroom or using a sleep mask.

The science: Melatonin is a chemical produced in the brain’s pineal gland at night time in order to regulate the body’s natural sleep/wake cycle. When there is even the slightest amount of light in your bedroom, your melatonin production is partially inhibited which interferes with your sleep.  (Reiter, 1991).
