Puberty.
The sweat glands become active when the body temperature rises.
There is no way to know the exact number of sweat glands that become more active in puberty. There are two types of sweat glands, eccrine and apocrine. The eccrine sweat glands are for cooling the body and are active your entire life and are located just about all over your body. The apocrine sweat glands are the ones that occur in places like your arm pits, crotch, and peri-anal areas. They are the one that increase their secretions after the onset of puberty.
There are about 2 to 3 million eccrine sweat glands all over your body.
To be eccrine, essentially, means to be of the sweat glands. An example sentence would be: His eccrine problem was very apparent.

The glands of the skin, or the integumentary glands, include apocrine and eccrine sweat glands, and sebaceous glands that secrete sebum, or skin oil.
Apocrine sweat glands become active at puberty, primarily due to hormonal changes, particularly the influence of androgens. These glands are located in specific areas of the body, such as the armpits and genital region, and they produce a thicker, odoriferous sweat when stimulated by factors like emotional stress or sexual arousal. Unlike eccrine glands, which are active from birth and help regulate body temperature, apocrine glands are associated with scent and are thought to play a role in social and reproductive signaling.

Eccrine (sweat) glands.
The Skin controls the activity of the eccrine sweat glands.
Eccrine are found on hands and feet to provide thermoregulation and apocrine connected to the hair follicle concentrated in the axilla, perenium and audtory
The most numerous types of skin glands are the eccrine sweat glands. These glands are found all over the body and are responsible for regulating body temperature through the secretion of sweat.
