Sweating and body odor are common when you exercise or you're too warm. They're also common when you're feeling nervous, anxious or stressed. Unusual changes in sweating — either excessive perspiration hyperhidrosis or little or no perspiration anhidrosis — can be cause for concern.
Changes in body odor also may signal a health problem. Some people naturally sweat more or less than other people. Body odor also can vary from person to person. See a doctor if:. Sweating and body odor are caused by sweat glands in your body. The two main types of sweat glands are eccrine glands and apocrine glands. Eccrine glands occur over most of your body and open directly onto the surface of the skin.
When your body temperature rises, these glands release fluids that cool your body as they evaporate. Apocrine glands are found in areas where you have hair, such as your armpits and groin.
These glands release a milky fluid when you're stressed. This fluid is odorless until it combines with bacteria on your skin. Mayo Clinic does not endorse companies or products.

For younger people, it generally occurs after prolonged exercise or outdoor activity, without adequate hydration. For older people, it can happen without exertion because of underlying medical conditions, medications or other factors like physical disability. Hot and humid weather makes cooling off through sweat evaporation ineffective.
The longer the exposure, the more dehydrated a person becomes. This can eventually lead to a body temperature above F 40 C , along with feeling faint, dizzy, nauseous, and confused. Without treatment, there can be serious complications from heat stroke," said Pathak. There are many other reasons why someone may not sweat. For instance, there could be nerve damage. Conditions that can lead to this type of nerve damage include diabetes, alcoholism, Parkinson's disease or direct damage to the skin, such as after trauma, said Bauer.
Sometimes skin diseases, such as psoriasis or heat rash, can interfere with normal sweat gland functioning, as well. Conditions called hypohidrotic ectodermal dysplasia and hypohidrosis, also known as anhidrosis, can also cause the sweat glands to malfunction.
Menopause can lead to the sensation of feeling hot or having episodes of "hot flashes" without associated sweating, as well, said Pathak.

Aging skin is less able to bounce back from wear and tear and wounds than younger skin. A new study identifies why. A group of scientists and dermatologists are now looking at the role sweat glands play in how aging skin recovers from wounds. The lesions were smaller than the diameter of a pencil eraser, performed under local anesthesia. The researchers had already determined eccrine sweat glands , which are located throughout the body, are important for wound closure. They are major contributors of new cells that replace the cells that were lost due to injury.
This finding led to a new research question. In young people, they discovered sweat glands contributed more cells to wound closure than in aged adults.
Fewer cells participating, spaced further apart, means a delay in wound closure and a thinner repaired epidermis in aged versus young skin. The differences in young and aged skin healing were clear from the beginning of the healing process. The skin was considered healed when the new growths merged together and the scab fell off the surface. Chronic sun exposure is an important factor that damages skin structures that normally support sweat glands.
