Because our brains are hard-wired to stay
Avoid light exposure at night as much as possible.” To reduce the amount of light in the bedroom, researchers recommend turning off lamps, computers, tablets, cell phones, and other light-emitting electronics before you go to bed.
Ancient Japanese lighting from a traditional Japanese hearth, oil lamp or candle (20–30 lux) could be healthier for children and adolescents because rapid and clear increase in melatonin concentration in blood seems to occur at night under such dim light, thus facilitating a smooth falling into night sleep.
Light at night “may affect our overall health via circadian misalignment in our daily life,” Obayashi wrote. This kind of disruption of our circadian clocks can lead to a host of issues, including sleep disturbances, mood disorders, cognitive impairments, metabolic dysfunction and cancer risk.
By reducing light exposure during sleep, we allow our bodies to naturally produce melatonin. This not only helps us sleep better but can also reduce the risk of various diseases such as obesity, diabetes, heart disease, and mood disorders.
As a general rule, it is best to sleep in as much darkness as possible. Pitch darkness reduces potential distractions and disruptions to sleep. Sleeping with a light on interferes with sleep cycles and causes more fragmented sleep, and these downsides may be greatest in the few hours before waking up.
Some research suggests that sleeping naked can promote better sleep, leading to various mental and physical health benefits. By encouraging core body temperature regulation, naked sleeping may help support reproductive function, skin health, cortisol levels, metabolic control, and more.
Contrary to what many believe, the black light is far from optimum for bed time. The same is true for white light. However, it's the blue light — yeah, the same one that your smartphone, computer, television screen emanates — that's most detrimental to sleep.

This low mortality is mainly attributable to a low rate of obesity, low consumption of red meat, and high consumption of fish and plant foods such as soybeans and tea. In Japan, the obesity rate is low (4.8% for men and 3.7% for women).
Consistently sleeping on wet hair can raise a person's risk of hair breakage, as well as other health concerns such as scalp infections. However, sleeping on wet hair from time to time isn't likely to cause any significant harm, dermatologists said.

Outdoor Home Lights Are Useless Without Witness
Research shows that leaving your lights on at night might not be effective at deterring crime if there is no one around to see it. Outdoor lights make the burglars harder to hide, but the lightning will be useless if no one actually sees the suspicious activity.

Sleeping with lights on can disrupt your circadian rhythm and hinder sleep quality. Artificial light, especially blue light, can suppress melatonin production. Excessive light exposure can impact your sleep-wake cycle and negatively affect your overall health.
These factors combine to produce the glow-in-the-dark effects you're familiar with. There all sorts of phosphors, both natural and man-made. For example, your teeth and fingernails contain phosphors, which explains why they glow under a black light.
Exposure to UVA from black lights is well below the recognised safe limits and is not hazardous to people using them, working in their vicinity or who have them in their home.
