Apocrine sweat glands are inactive until they are stimulated by hormonal changes in puberty. Apocrine sweat glands are mainly thought to function as olfactory pheromones, chemicals important in attracting a potential mate. The stimulus for the secretion of apocrine sweat glands is adrenaline, which is a hormone carried in the blood.
According to another suggestion, apocrine sweat glands were developed in the earliest period of human evolution via natural selection as a means of defence from predators as a warning signal, and that is why these glands are activated in the moments of emotional or physical stress.
