Disadvantages of Blue Light Emitted from Screens: Insomnia has become a common problem due to increasing dependence on gadgets, the habit of using mobile phones all day, and today's hectic and irregular daily routine. Despite the day's mental and physical fatigue, sleep remains elusive. In this situation, the National Health Mission has provided important advice for better and deeper sleep. According to experts, one should completely stop using mobile phones, TVs, laptops, or any other screen at least an hour before bedtime.

How does blue light emitted from screens disrupt sleep?
Blue light emitted from screens keeps the brain active and suppresses the hormone melatonin, which helps induce sleep. This delays sleep onset and leads to fragmented sleep. Consequently, fatigue, irritability, and increased stress are experienced upon waking in the morning.
Harmful effects of prolonged screen time
This long-term habit has adverse health effects, such as weakened immunity, lack of concentration, obesity, and an increased risk of heart disease. According to health experts, staying away from screens before bed is the easiest and most effective way to achieve deep and restful sleep.
Practice these calming activities at night.
In the evening, engage in calming activities, such as reading a good book, listening to light music, deep breathing, light family conversations, and light stretching or meditation. These activities calm the mind, reduce stress, and prepare the body for sleep. Also, keep your bedtime consistent every day, keep your room dark and cool, and avoid caffeine or heavy meals at night.
Why is good sleep important?
Experts say that 7-8 hours of good sleep is essential for all ages. Young people and children, in particular, suffer from sleep deprivation due to excessive screen time. If you also scroll through your phone late at night and feel tired in the morning, then try to change this habit from today on.
