We can probably all recall a time when we were kids and fell asleep with the lights on. It was the only way we could keep the closet monsters at bay. Furthermore, some adults may prefer to leave the lights on for reasons other than darkness. However, it turns out that the real threat has been lying in plain sight all along.
According to one study, nighttime exposure to artificial light increases the chance of infertility. The experiment used the female mice. Infertile mice were more likely to be those who slept with the light on at night. Circadian rhythms (the body’s internal clock) are also thought to influence the timing of the reproductive process in women.
Another study looked at the effects of nighttime light exposure on nurses working night shifts. They complains that this affects for the menstrual cycle also.
Melatonin not only reduces body warmth but also blood pressure. Melatonin production is inhibited if you are exposed to light at night. Your blood pressure rises as a result. As a result, regular swings can raise the risk of heart disease and stroke.
too much artificial light at night can caused for a sluggish metabolism. Furthermore, sleep deprivation and disruption of circadian rhythms may contribute to obesity. A survey of almost 43,000 women found that those who slept with the television on gained weight. Regardless of the quality or duration of their sleep, the shift occurred.
Even a single light source can disrupted the hormonal balance. Light from smartphones, televisions, and laptops caused for the melatonin deficit. Also, it affects for other biological processes. Melatonin affects at initial stage. Sleep deprivation raises aging hormones while lowering anti-aging hormones.
According to a study, it will affect for the depression also. Alternatively, disrupting the circadian rhythm is likely to exacerbate depressive symptoms already present. Red light, on the other hand, has fewer negative effects since we are less sensitive to red wavelengths. It’s even used to treat the blues in rare situations.
