Sweating: An Overview

Scientifically known as perspiration, sweating is a normal body function through which fluids are secreted out. This fluid often contains salt and is released from the sweat glands of mammals. There are two types of sweat glands, namely eccrine glands and apocrine glands


Eccrine glands are found normally over the body and skin and apocrine glands are usually found under the armpits and other areas of your body.

Sweating is often conducted as a process of thermoregulation in human beings. Thermoregulation is an activity through which an organism keeps its body temperature adapted to its surrounding temperatures. Normal amounts of sweating are necessary for the body. But if you experience excessive sweating or not enough of that, it can be an indication of some health problems.

What are the factors that affect sweating?

Many factors affect the process of sweating. Some of them are provided below:

  • The weight of your body: People with more body weight usually sweat more. This is because compared to leaner people they have more body mass and produce more heat. This can lead to more sweat as a result. Also, as fat people tend to have a wider body surface, they need more sweating to cool the body down.
  • Physical fitness: Another factor that can affect sweating is physical fitness. This is because they tend to have a higher intake of oxygen than people who don’t engage in fitness activities.
  • DNA: One of the crucial factors that determine how much you sweat is your DNA. Some people have more predisposition to sweating compared to people who sweat less. 
  • Acclimatization: This means adapting to your surroundings’ temperatures efficiently. If you are someone who spends regular time in the sun, you start adapting to this temperature more and as a result, you tend to sweat more.
  • Status of your health: Health status is another factor that decides the amount of sweat one person produces. If someone has hormonal fluctuations, it can affect the quantity of perspiration too.  Even conditions like colds, flu, etc can have a role in sweating.

Why do fat people sweat more than others?

Another reason behind fat people sweating more is their sweat glands are spread all over the body other than the armpit.

Compared to leaner people, their sweat glands are found more in parts like the face, neck, etc.  Their sweat glands are more extensively spread out which results in more sweat.
