Every time we feel like hot, our bodies are releasing sweats but do we really know them? Well, if not, let us talk about it!

Perspiration comes from the sweat glands in the skin of mammals like us humans. With this, the production of fluids in our skin, known as “sweat”, is occurring. In our case as humans, we have two sweat glands; they are the eccrine glands and apocrine glands.

Sweating for us is mainly our way of thermoregulation which we can get from the proper secretion of the eccrine glands with water inside us. During a hot weather, we are producing more amount of sweat. This brings us a cool sensation due to the evaporation of water in the outer layer of our skin. According to the studies done by the experts, average men perspire much more quickly and sweats twice as much when they are in a work than women do.

Perspiration is an important thing for us since it gives chances for our body to control its temperature. It leads us to have a decrease in our temperature by evaporative cooling we are experiencing in our skin surface whenever the sweat evaporates with the air.

Our nerves stimulate the sweat glands in two ways that give us this perspiration every time. It happens when we are experiencing an emotional stress and physical heat. When we are sweating as an effect of our emotions, the sweats are limited to our armpits, palms, forehead, and soles. On the other hand, the sweats that we are producing when we are at a physical heat come all over our body.

We all know that sweat is not the type of water that is pure. Sweats always have an amount 0.2–1% solute. Since we are perspiring when we are experiencing to the heat around us and in our body due to some conditions, we will also have our temperature changes in order for us to adapt whenever we are moving from places where the temperature is different from other place we used to stay. It leads us to our sweating mechanisms. We call this process as acclimatization. It is the extreme amount of increasing sweat together with its solute structure losses. The amount of water we are giving in our daily life is inconstant in high level (from 100 to 8,000 mL/day). The decrease in our solute can reach the level as much as 350 mmol/day or 90 mmol/day acclimatized of sodium when we are having the most extreme cases where we are sweating. When we are having an exercise, we can produce an average amount of sweat of 2 litres of water/hour. However, in a cool climate and there is lack of exercise, we can release sodium in a very low amount.
