What causes men to feel hot all the time?

Men may feel hot all the time due to several factors, including higher muscle mass and metabolic rates compared to women, which can lead to increased body heat production. Hormonal fluctuations, particularly levels of testosterone, can also affect body temperature regulation. Additionally, factors such as stress, diet, dehydration, or underlying medical conditions like hyperthyroidism might contribute to a persistent feeling of heat. Lifestyle choices, including exercise and clothing, can further influence how hot a man feels.
