Sweat is a clear, salty liquid made by glands in your skin. Sweating is how your body cools itself. You sweat mostly under your arms and on your feet and palms.
Odour
Sweat can smell when it mixes with bacteria on your skin. Bathing regularly and using an antiperspirant or deodorant can help control the odour.

Sweating a lot is normal when:
- it is hot;
- you exercise;
- you are anxious;
- you have a fever;
- you are going through menopause.
Sweating too much: hyperhidrosis
If you often sweat too much, the condition is called hyperhidrosis. Causes include thyroid problems, nervous system disorders, low blood sugar and other health problems.
Sweating too little: anhidrosis
Sweating too little is called anhidrosis. It can be life-threatening, because your body can overheat. Causes include:
