The habit of having fun with your smartphone before going to bed is a modern way to relax after a busy day.
Before going to bed, many users are addicted to social networks, watching videos and chatting with loved ones, not noticing that the sleep pattern is gradually getting off, fatigue and irritability are accumulating. Tracking the cause of sleep disturbance is easy - just limit the use of smartphones in the evening. The displays of today's gadgets are for the most part a source of light in the blue part of the spectrum, and the impact of such light on the user's body cannot be underestimated.
The body's response to blue light
Melatonin is a hormone that is released after dark. It signals the body about the upcoming rest and causes a desire to sleep. The light from the screen sends a signal to the brain that darkness has not yet come, therefore, the production of melatonin is not required. Problems with the timely generation of melatonin can (with a tiny probability) cause serious diseases in the future, such as cancer, diabetes or obesity. That is why scientists talk so much about the dangers of working with gadgets in the evening.
The main recommendation of doctors is to stop using smartphones two hours before bedtime. It is not necessary to put the device aside if it is nine o'clock in the evening, and the user is used to falling asleep at midnight. But if you had to use the phone during an evening rest, a device with a small diagonal will do less harm. In this regard, it is recommended to at least give preference to smartphones, and leave tablets until morning.
E-link out UV protection
Given that not all gadgets emit blue light equally, you can use devices whose display is made using the "electronic ink" technology. Typically, e-books are equipped with such a display. There is also a "domestic" YotaPhone 2 with a second screen.
The main advantage of E-link displays is that the screen is not backlit, so the strain on a person's eyes is identical to that of a regular paper book. For those who can't fall asleep without reading a chapter or two before bed, this solution will help maintain health and get great sleep.
It is important that for comfortable use of devices with E-Ink technology, you need a light source. Ophthalmologists do not recommend the use of special lamps that are attached to the body of the device. It is better to give preference to a high-quality table lamp.
Software manufacturers for the Android and iOS operating systems have already created programs that control and. Some smartphones have a special UV protection mode that minimizes blue tints on the display. When using the gadget in the dark, it is recommended to enable this function.
