First, upon waking in the morning
This glass of water is very important. Morning is when the body's blood pressure rises physiologically, platelet activity increases, and thrombosis is prone to form. Fat deposits on the blood vessel wall become loose and fall off. Coupled with a night's sleep, urination, skin evaporation, and breathing through the mouth and nose all lead to significant water loss, increasing blood viscosity and making it easy for thrombi to form in the blood.
Second, half an hour before bedtime
At night, when people sleep, blood flow slows down. If blood viscosity increases, it is very easy to develop thrombotic diseases. Drinking an appropriate amount of cool water can dilute the blood and prevent thrombosis.
Third, upon waking up in the deep of night
Cerebral thrombosis and myocardial infarction often occur around 2 a.m., especially in summer when sweating is heavy or when symptoms of diarrhea or vomiting appear. Therefore, for the prevention and treatment of heart disease, drinking the right water has a significant effect. These three time periods for drinking water are the most effective for preventing and treating heart disease.
