Sweating more in summer, and more potassium ions are lost with sweat, leading to hypokalemia, which will cause fatigue, dizziness, headache, loss of appetite and other symptoms. The most effective way to prevent potassium deficiency in hot weather is to eat more foods containing potassium. Fresh vegetables and fruits contain more potassium, so you can eat more strawberries, apricots, lychees, peaches and plums. Vegetables include green onions, celery, edamame, etc., and are also rich in potassium. Tea also contains more potassium. Drinking more tea in hot weather can relieve summer heat and supplement potassium, killing two birds with one stone. In summer, the human body sweats a lot, and sodium chloride loses more, so we should pay attention to supplementing salt while replenishing water. Drink some salty boiled water every day to keep the acid-base balance and osmotic pressure in the body relatively stable.

Dark clothes will absorb sunlight and make people's body temperature rise and dry; At the same time, mosquitoes have the habit of blackening, and dark colors are easy to attract mosquitoes, especially black.

3, skin itching precautions

When you go out in summer, your skin itches because of the sun. When it is dry and painful, you can apply some ointment such as toner. Do not scald with hot water or wash with alkaline soap, so as not to irritate the skin and aggravate the symptoms.
