You shouldn't take a bath after a big meal or when you are hungry. Taking a bath after a full meal, the blood vessels in the epidermis of the whole body are stimulated by hot water to expand, more blood flows to the body surface, and the blood supply in the abdominal cavity is relatively reduced, which will affect digestion and absorption, cause hypoglycemia, and even collapse and faint.
Bathing will dilate blood vessels in the skin of limbs, and blood will gather on the body surface, which will reduce gastrointestinal blood flow, digestive juice secretion and digestive function. If you often take a bath after meals, it will cause gastrointestinal diseases. In addition, it is easy to cause angina pectoris and myocardial infarction in patients with coronary heart disease, especially in patients with hypertension and hyperlipidemia. It is more appropriate to take a bath after meals 1 ~ 3 hours. No one should take a bath immediately after a meal.
Extended data:
The temperature of the bath water should be close to the body temperature, that is, 35 ~ 40℃. When the water temperature is too high, the blood vessels in the epidermis of the whole body dilate, and the blood flow in the heart and brain decreases, resulting in hypoxia. When pregnant women take a bath, the water temperature should not be too high to prevent fetal hypoxia and affect fetal development. Take a cold bath in summer.
If the bath water is too cold, the skin pores will suddenly close, the blood vessels will contract sharply, and the heat in the body will not be emitted. Especially on hot nights, people often feel weak limbs, shoulder and knee pain and abdominal pain after taking a cold bath, and even become the inducing factors of arthritis and chronic gastrointestinal diseases. In summer, the water temperature of a cold bath should generally not be lower than 10℃.
