Why is the hotter the weather, the more serious the body edema?

Edema has nothing to do with the weather. It is a symptom of endocrine disorder and water metabolism disorder. This is a symptom of malnutrition. I'm not kidding you. Your problem is caused by your lack of food. We often say that we should eat rice as medicine, not medicine as rice. I suggest you: give priority to rough tea and light rice, eat less oil and sugar, eat less cooking, quit fat and eat more bowls of rice. Steamed vegetables and stews are the main things, which are the specific meanings of light diet that we often say. These problems will follow when the amount of food increases. If you can eat three bowls and five bowls every meal, I guarantee that all your problems will run away.
