In recent years, the concept of healthy aging in China has attracted more and more attention from the international community. The United Nations puts forward that healthy aging is the global goal to solve the aging problem. For this reason, mobile phones for the elderly are widely used by the elderly, which has an important impact on the popularity of telecommunications terminals in the country, allowing the elderly to fully experience modern life and launch mobile phones suitable for the elderly.

Matters needing attention in using the aging machine:

1. Don't use old people's mobile phones with miscellaneous brands. The mobile phone of the old people with miscellaneous brands has great radiation, which is very harmful to the body and may even cause cancer. It is suggested that parents should be given a mobile phone with a small radiation like 2 1 g, but at the same time, parents should be reminded not to sleep with their ears covered, no matter how small the radiation is. ?

2. When you are ready to sleep, you'd better not play with your mobile phone. You need to relax your nerves when you sleep, and all parts of your body are at rest. If you still play mobile phone before going to bed, it will easily affect people's neural regulation, leading to poor sleep quality, insomnia and dreaminess.

Don't lie down and play with your mobile phone for a long time. Lying down and playing with mobile phones for a long time will put pressure on the cervical and lumbar vertebrae. Older patients with cervical spondylosis will make it more serious, and those who don't may increase the chance of getting sick.

4. Don't play mobile phone in bad light. In poor light, the pupils of people who play mobile phones will be dilated. In the long run, with the growth of age, their eyesight will be seriously lost and they are prone to eye diseases such as glaucoma.
