SAEDNEWS: Have you ever wondered why we turn off the lights when we sleep and why sleeping in a lit room is strongly discouraged? There is a very important reason behind this.
According to SAEDNEWS, You’ve probably experienced sleeping with the lights on in your room. Regardless of the reason, sleeping with a lamp or light on has drawbacks that prevent you from getting the full benefits of your sleep. In this section, we will explain what happens to your body when you sleep with the lights on.
Studies show that exposure to artificial light at night increases the risk of infertility. This experiment was conducted on female mice. Those mice that slept in bright light at night had higher infertility rates compared to mice that slept in darkness.
Their circadian rhythm, or internal body clock, was also disrupted. Therefore, sleeping with the lights on at night affects the reproductive system in women.
Another study found that nurses working night shifts are more likely to experience this problem and have disrupted menstrual cycles.
Exposure to light at night not only reduces melatonin but also raises blood pressure. If you are exposed to bright light at night, melatonin production is suppressed, leading to increased blood pressure. Such fluctuations can increase the risk of heart disease and stroke.
Prolonged exposure to artificial light at night causes a decrease in metabolism, disrupting the sleep cycle and circadian rhythm, which can contribute to obesity.
A study conducted on 43,000 women showed that those who sleep with the TV light on at night tend to gain weight. This change occurs regardless of sleep quality or duration.
Even having just one light on can disrupt hormonal balance. Light from mobile phones, televisions, or computers causes a reduction in melatonin and also disturbs biological processes. Melatonin is the first to be suppressed in such conditions, disrupting people's sleep. Hormones are affected as well, with decreased secretion of anti-aging hormones.
A study in this area shows that exposure to light at night increases the risk of depression. Disruption of the circadian rhythm worsens depressive symptoms. Red light may have fewer harmful effects because people are less sensitive to red wavelengths.
Although in some cases blue light therapy is used, it is generally better to avoid exposure to any light at night.
