Can upper respiratory tract infection cause hot flashes?

Upper respiratory tract infections may cause symptoms of hot flashes. When a virus or bacteria invades the body during an upper respiratory tract infection, it triggers an immune response that may disrupt the function of the body's temperature regulation center, leading to episodes of hot flashes. According to information from reference articles, certain symptoms of upper respiratory tract infections—such as influenza—can cause general malaise and fever, which may be associated with hot flashes. Following an upper respiratory tract infection, patients may remain in a weakened state, making them more susceptible to external environmental factors; for example, changes in ambient temperature could also trigger hot flashes. Therefore, upper respiratory tract infections can indeed potentially cause hot flashes, although the specific presentation may vary depending on individual differences and the severity of the illness.
