The inability to sweat is known as Anhidrosis. Lack of sweating can be a cause of a number of factors, including genetics related reasons and a symptom of certain medical conditions. What sweating does is cool the body down, and if you are facing lack of sweating then your body can very easily overheat its self. Even though it is generally normal for some people to sweat lesser than others, in case you are experiencing not sweating during exercise or when the temperature you are confined to is genuinely hot, then it is always advisable and safer to consult a doctor.
Here are a few things important to know about lack of sweating and sweating itself:
One of the most common causes of not sweating during exercise is the lack of intake of fluids either before, during or after a workout session. Considering, you are not consuming enough liquids as it is, or are visiting the loo a little too often, there is not much fluid in the body that can surface as sweat.
Another cause of lack of sweating is lack of intensity in a workout routine. If you are not pushing your body to reach a certain high core temperature, your body will not feel the need to cool down and that will result in a lack of sweating. Take walking for example as a form of exercise;it will not make many people sweat until andunless the air temperature is high enough to stimulate the sweat glands.
However, in a scenario where you are consuming enough fluids during, before and after exercising, and not visiting the loo all too often and yet not sweating during exercise, then that could possibly be because of an underlying medical condition or disorder. Neurological disorders, such as Guillain-Barre syndrome and certain skin diseases which channelize themselves into blocking the sweat glands against activation are certain common medical causes that can lead to lack of sweating. Other medical disorders that may cause lack of sweating include congenital disorders, nerve related damage or disorders, trauma suffered by the sweat glands and genetic issues. There even exist certain drugs that bear the side effect of blocking the sweat glands, causing lack of sweating.
There are certain misconceptions related to lack of sweating that need clarification. Most people who find themselves not sweating during exercise tend to associate this lack of sweating to genetics. Even though it is very much possible that genetics is the reason why they are confronting a lack of sweating, it does not change the fact that you are at a possible risk for such a bodily behavior if you are engaging in vigorous workouts. In such a case it is advisable to consult a doctor for confirmation sake, whether there is an underlying reason to this lack of sweating or not. If you are not sweating during exercise and find yourself overheating, you must let go of all activity and take a cold shower immediately to cool the body down or splatter cold water over your face and other visible areas of the body. Also, make sure to consume plenty of fluids and try finding a shade or a relatively cooler environment where you can rest a while and get your body to reach a normal temperature again.
