My throat is dry and I always want to drink water. Do I still feel thirsty after drinking more water?

I am particularly thirsty in summer and need to drink water at any time. How to drink water is scientific? First, don't be thirsty when drinking water. When thirsty, it means that the water in the human body is out of balance and the cells begin to dehydrate. At this time, it is too late to drink water. Second, don't drink a lot of water at a time, so drinking water will make the stomach difficult to adapt and cause adverse consequences. Third, it is not advisable to drink water before or during meals, because drinking water before or during meals will dilute the digestive juice, which is not conducive to the digestion and absorption of food and is not good for the health for a long time. Fourth, getting up in the morning and drinking some water first can replenish the water consumed overnight, reduce the blood concentration, promote blood circulation and maintain the normal level of body fluids. Sweating and dry throat in summer, if someone drinks a lot of water at once, it will increase the burden on the heart, reduce the blood concentration, and even cause palpitation, shortness of breath, sweating and other phenomena. In this case, it is more difficult for blood to replenish water to cells, so it will always feel that it does not quench thirst. Drinking salt and boiled water in moderation is also a good way to prevent heatstroke. Human sweat contains a lot of salt, which is lost due to excessive sweating due to labor or exercise. Sometimes drinking water can't quench thirst. The root cause is the insufficient supply of salt.
