We are more likely to sweat a lot when the surrounding temperature is hot and less when it is cold.
Sweating excessively is an abnormality of perspiration and known as hyperhidrosis whereas sweating less in hot environments can be a warning alert for a bad health.
Understanding Anhidrosis or Hypodrosis
Inability to sweat normally is termed as anhidrosis or hypohidrosis in medical studies. But there is a slight difference between the two terms.
When people do not sweat at all it is anhidrosis and when they sweat less it is called hypohidrosis. The condition can be dangerous for health or life-threatening.
Anhidrosis or hypohidrosis occurs due to several reasons and sometimes it is not possible to find out the actual cause of it.
The normal sweating occurs when the temperature control center in the body detects that the body temperature is too high and nerves send stimulatory signals to the sweat.
Therefore it can be concluded that anhidrosis or hypohidrosis is a dysfunction of temperature control centers located in the brain or with the nerves that control sweat glands.
Moreover, it may occur when there is a problem with sweat glands or when there is insufficient water in the body.
Symptoms and signs of Anhidrosis
The main sign of anhidrosis is lack of sweating. This can happen all over the body, in a specific area or in different parts of the body simultaneously.
The lack or absence of sweating rise the temperature of the body. Other symptoms may include muscles cramps, fatigue, weakness or dizziness and high body temperature.
When anhidrosis occur due to dehydration the symptoms will be severe headache, confusion, changes in blood pressure, fluctuation is pulse or seizures.
People whose certain body parts are affected make the unaffected parts to sweat excessively.
If most of the body parts are affected hot temperatures or physical exertion may lead to heatstroke. Anhidrosis or hypohidrosis is diagnosed by medical tests which stimulate sweating to confirm its presence and to measure the distribution of sweating.
In some cases, skin biopsy may be done.These medical tests confirm the lacking of sweating but it does not determine the cause.
Treatment for Anhidrosis or Hypohidrosis
Its cure depends on the cause, which means that in order to treat hyphidrosis the reason must be diagnosed. If you notice that you are sweating less than before in the same previous conditions, you need to contact healthcare professional.
Some measures should be taken out immediately such as resting in a cool environment, staying hydrated by drinking plenty of water, wearing light clothes, moistening body by pouring cold water.
If anhidrosis is not treated properly, it may cause coma, heat stroke, hyperthermia or heat exhaustion.
Concluding to that, anhidrosis should be taken seriously as it may cause multiple side effects.
