How many hours of online time is a healthy online time.

It is best not to surf the Internet for more than two hours. Close your eyes and rest every two hours, otherwise your eyes will be dry and have a headache, and your eyesight will decline in the long run. If you need to work, it is recommended to eat more food that supplements your eyes, such as carrots, spinach and liver foods, and drink some chrysanthemum tea or cassia seed tea. Pay attention to eye hygiene, put some green plants next to the computer and set the color of the computer screen to healthy green. In short, regular rest is the most important thing. Here's to health! ^^
