Is sleeping with LED lights bad?
It’s well-documented that exposure to blue light can negatively impact your sleep quality. Electronic screens, LED lights, and fluorescent lights can all contain blue light. One small older study from 1991 and one 2016 study on mice found evidence that green light could also negatively impact melatonin levels.
Is it good to sleep in pitch black?
Pitch black darkness is essential for the body to fall asleep. In absence of light, the brain sends a signal to the body indicating that it is time to rest. In addition to regulating our melatonin levels, sleeping in complete darkness helps lower the risk of depression.
Why you should sleep in complete darkness?
Darkness is essential to sleep. The absence of light sends a critical signal to the body that it is time to rest. Light exposure at the wrong times alters the body’s internal “sleep clock”—the biological mechanism that regulates sleep-wake cycles—in ways that interfere with both the quantity and quality of sleep.
Is it better to sleep with or without a bra?
By wearing a bra to bed, which is wrapped firmly around the ribcage, your ribs can’t fully and freely expand. Sleeping in a bra can make your breathing more labored and shallow, lowering your usual intake of oxygen. On the other hand, sleeping without a bra better allows you to breathe (and rest) easy.

Why are people exposed to artificial light at night?
Shift workers, who are often exposed to artificial light at night and contend with ongoing disruption to circadian rhythms and biological clocks, face higher risks for diabetes, according to numerous studies. More than 70 million American adults—roughly 29 percent of the population—suffer from high blood pressure.
