Using Smartphone, Tablets During Bedtime May Be Ruining Your Sleep

A team of researchers recently analysed a group of people aged 17-42, who wore short-wavelength blocking glasses three hours before bedtime for three weeks. It showed that 58 per cent of the people have an increase in their night time melatonin levels, which is a chemical that signals the body that it’s time to sleep. Sleeping is an important part of our life as this is the time in which most parts of the body are relaxed after the regular work routine and also helps in the regeneration functionality of it. The blue light which emits through the devices decreases the sleeping time which can impact the overall productivity of the body. A normal body requires 8 hours of quality sleep and sleep for almost 24 hours in a day can actually increase the sleeping duration for almost 24 minutes.

The largest source of blue light is the sun and most of the LED devices that we use in our households including the smartphones. Whenever the blue light enters in our body, it boosts the alertness and regulates our internal body clock. The alertness will tell the body that it is not the time to sleep, and most of the time at night you are sleepless while using your smartphone. The most common example is the sun rays in the morning which trigger the body to wake up in the morning, due to the presence of blue light and it makes you stay awake during the whole day. In recent times, most of the devices are equipped with night mode settings which will block the blue light emission from the smartphones and your exposure will be comparatively less. You can also use the blue blocking glasses that can improve your sleeping time and quality.
