Heat sensitivity refers to the body's reaction to high temperatures, which can vary from person to person. Some individuals may experience discomfort, fatigue, or even heat-related illnesses like heat exhaustion or heat stroke when exposed to hot conditions. This sensitivity can be influenced by factors such as age, hydration levels, and underlying health conditions. Certain groups, such as the elderly or those with chronic illnesses, are more prone to heat sensitivity. It's important for these individuals to take precautions during hot weather, such as staying hydrated and avoiding strenuous activities. Understanding heat sensitivity can help prevent serious health risks associated with extreme temperatures.
