If it is a fixed telephone, squeezing your ears for a long time will really affect your hearing, but it has little effect, so don't worry too much.

If it is a mobile phone, the radiation is very large. It not only affects hearing, but also reduces people's immunity, which has a great impact on some health problems such as fertility. And the less power the mobile phone has, the greater the radiation. It's best not to make a phone call when there is only one box left! !

My very best wishes to your health
