Studies have shown that a daily dose of blue light from digital screens can have adverse effects on your health. It is also harmful to sleep because of its effect on the circadian rhythm. You are not at peak performance during these hours of the day, and it can increase cardiovascular risks. However, the effects of blue light are not immediate. The National Heart, Lung, and Blood Institute recommends that you limit your screen time to two hours a day.
Blue light is particularly harmful to eyes because it interferes with the circadian rhythm, which regulates how much sleep you get. Research shows that taking in blue light for just two hours at night can reduce the production of melatonin, a hormone that helps you sleep. In other words, blue light tricks your body into thinking it is daytime instead of nighttime. Consequently, you wake up feeling tired and groggy.
Production Of Melatonin
The blue light can disturb our circadian rhythm, which is necessary for sleeping. Studies have found that two hours of exposure to blue light in the evening can decrease the production of melatonin, a hormone that is essential for sleep. The body produces melatonin during daylight, so exposing it to blue light during the night will trick it into believing it is daytime. While we all need to sleep, absorbing blue light while awake can lead to problems with sleep.
Affect Our Sleep
Research has also found that blue light can affect our sleep. A systematic review of nine studies has shown that nighttime exposure to blue light can lower the levels of melatonin in the brain, a hormone that helps us fall asleep. If we’re exposed to blue light in the evening, our bodies might have trouble falling asleep at night. This means that we’ll feel tired and groggy in the morning. Therefore, we’ll need to take action immediately to minimize our exposure to blue light during the day.
Several studies have shown that blue light can have negative effects on people’s sleep. One study found that blue light suppresses the production of melatonin, a hormone that helps us sleep. While this effect is limited to a small number of people, exposure to blue light can have serious consequences for the health of adults and children. In particular, children are at risk, because their pupils are large and their arms are shorter than their parents. As a result, they are more likely to experience a decreased level of melatonin than adults.
The use of digital devices during the day can also affect the production of melatonin. This hormone is responsible for the creation of sleep-inducing hormones, and if this hormone is disturbed, the person will feel tired and less rested in the morning. Interestingly, this is the same for children. Despite this, the effects of blue light are minimal in adults, while they may be dangerous for children. So, it is a good idea to avoid exposing kids to blue light at night.
