Sweating helps balance body temperature and is defined as the release of a salt-based fluid from sweat glands. It can be caused by an emotional state, a serious medical condition or even menopause and pregnancy (due to hormonal changes).
Apocrine glands constantly release sweat, and during puberty there is an increase in hormones that make the sweat glands more dynamic. Sweating through the apocrine glands usually starts around puberty, and doesn't really stop, so if you're not sweating at all while hiking, it could be a sign of a medical condition.
These different types of sweat might help you understand sweat:
Salty sweat
Just like tears, it is normal for sweat to be salty. However, if it is unusually salty to the point of burning your eyes, then this is a sign that you may be deficient in sodium.
One very important ingredient for a healthy body is hydration, and although it sounds counterintuitive, you could be dehydrated when you lack sodium in your diet. You could drink more energy drinks to increase the electrolytes that manage your sodium and potassium levels.
This will prevent super salty sweat
You barely break a sweat
Everyone's body is different, some people sweat more and some less, and this is completely natural. However, like everything else, too much or too little of something is usually not a good sign.
If you hardly sweat on a hot summer day or while riding a bike, it means that your sweat glands are not working well. This is a serious condition called anhidrosis and it can affect the whole body. This leads to overheating, heat exhaustion and heat stroke, all of which are alarming and life-threatening.
Excessive sweating
Not only can people not sweat at all, but they can also sweat excessively, and this condition usually goes unnoticed and neglected. Excessive sweating is called hyperhidrosis and can happen even during cold weather for no apparent reason.
It can also happen to women during menopause. Sometimes this condition can be dangerous. If you experience sweating and weight loss, sweating that occurs mostly during sleep, or chest tightness during sweating, then it's time to call your doctor. There is no need to worry because it can be diagnosed with various tests prescribed by your doctor.
