Summer Eating Bananas and Watermelons for Comfort in Hot Weather
Every summer, some people feel low-grade fever, general fatigue, lethargy, lack of appetite, gradual weight loss, and decreased heat tolerance, often prone to heatstroke. But these symptoms typically resolve naturally by autumn—this is commonly known as “summer discomfort.”
This “summer discomfort” is not due to structural disease but mostly caused by autonomic nervous system dysfunction. Medical research indicates that “summer discomfort” is associated with potassium deficiency. Potassium is primarily located inside cells, working with sodium outside cells to maintain normal osmotic pressure and acid-base balance, and sustaining nerve and muscle excitability. Potassium is vital for nerve impulse transmission, blood coagulation, and overall cellular function. It helps calm emotions, suppress pain, and prevent infection. In hot weather, excessive sweating leads to potassium loss, compounded by inadequate intake, affecting mood and bodily functions, thereby triggering “summer discomfort.”
Therefore, during summer, people should increase potassium intake in their daily diet. Tests show bananas contain the highest potassium content among all fruits. Eating more bananas, watermelons, and other potassium-rich foods is an excellent way to replenish potassium. Other foods rich in potassium include legumes and their products, potatoes, purple laver, kelp, and drinking tea in small, frequent amounts is also an effective method of potassium supplementation. For those with severe “summer discomfort,” taking vitamin B1, vitamin C, and oryzanol under medical guidance may help regulate the autonomic nervous system, eliminate low-grade fever, and improve symptoms.
