How much you sweat depends on your sweat gland secretion ability. Generally speaking, fat people will sweat more easily than thin people, because the total calorie consumption will be greater. However, it does not rule out that there is a person who broke up with a particularly severe sweat gland secretion. Moreover, people who work at heights are more likely to come out in summer. When outdoors, they should pay more attention to hydration to avoid heatstroke.
