Control the amount of drinking water.
A healthy person should drink at least 7-8 glasses of water (about 2.5 liters) every day. When strenuous exercise or hot weather, you should increase the amount of drinking water accordingly. Getting up in the morning is the key moment and the best time for the body to replenish water in the new day. For ordinary people, drinking more than 2000 ml of water every day may lead to an increase in intraocular pressure. This requires special attention.
2. Judging from urine.
In fact, sometimes we can judge whether we have drunk enough water from some physical phenomena. For example, judging from the color of urine, if urine looks like lemonade, you have drunk enough water. If the urine looks like apple juice and looks thick, it means you haven't drunk enough water. You should drink more.
