First, live in time. Go to bed late and get up early in summer, and take a nap at noon. Remember not to sit, lie down or sleep for a long time in the corridor, under the eaves or in the shade of the vents. Electric fans should not be used for a long time, because in summer, the outside is steaming at high temperature, sweating a lot, and the pores are wide open, which makes it easy to catch cold. If it is blown for a long time, it may cause headache, lumbar muscle strain, facial paralysis or muscle pain.
Second, adjust the diet reasonably. In summer, people's appetite decreases, so they should eat light and digestible food and eat less greasy or fried food. The intake of protein should be sufficient, and it is best to eat foods with high protein content, such as fish, eggs, milk and bean products. Of course, fresh vegetables and fruits are indispensable. In addition, due to excessive sweating in summer, the body loses a lot of water and salt, which will lead to blood concentration and affect blood circulation, especially in elderly patients with hypertension and cerebrovascular sclerosis. So pay attention to drinking a small amount of water many times, and don't wait until you are thirsty. But don't drink too many cold drinks, and don't eat more food like ice cream.
Third, it is not advisable to take a cold bath for a long time. Old people take a long cold bath or soak in cold water for a long time, and their body temperature will suddenly drop, making them vulnerable to cold, making their joints sore and their limbs numb. Fourth, we should pay attention to heatstroke prevention. It is hot and humid in summer, so it is advisable to prevent the sun from shining and lower the room temperature. The room should be ventilated and cool as far as possible. Open the window in the morning and close it before ten o'clock to prevent the invasion of outdoor hot air. In addition, some appropriate heatstroke prevention drugs should be prepared at home, such as Huoxiang Zhengqi Water, Refreshing Oil, Ren Dan and Fengyoujing.
