Our bodies naturally perspire. We sweat all the time - not only we are exercising. Even though we are not aware of it, the survival mechanisms of our body are doing their work. This also includes the activity of our sweat glands, which are spread all over our bodies - from head to toe. They are constantly reacting to our environment and to what is going on inside of us, even when we are sleeping.
In this article, we will present you with 8 reasons explaining why sweat is good for our bodies. We will also try to point out some commonly spread misconceptions about human transpiration. Knowing the facts will give you some insight into your own body and may also give you some extra motivation for your next sweaty workout!
We human beings are homeothermic. This means our bodies need to constantly maintain a core temperature of around 37°C to keep bodily functions working. But since the ambient air temperature varies a lot, our bodies are equipped with an ingenious regulation system, which helps in creating a balance between the inside and outside temperatures. To lessen the heat in our body, for example when we do sports or on a hot summer day, a thin layer of sweat covers our skin to cool the organism down, this is referred to as latent heat. Sweat protects us from overheating!
Sweat is a natural moisture for the skin. It increases skin turgor, which is the ability of water to bind with other molecules. Thanks to this property, the sweat can extract some secretions of the skin and make it soft.
With sweat, we excrete several toxic substances: For example, waste products from the kidneys and liver can be eliminated this way. This is also why we can observe stronger sweating after the alcohol consumption. Our pores open up and allow a molecule exchange with the environment. Remember this fact and make sure you clean your body regularly to keep the pores free. In the summer time, it is recommended to wash the face a minimum of three times a day to prevent skin irritations and spots from building up.
Regular workout leads to a greater calcium storage capacity in the bones and a greater excretion of water and salts from the body via sweat. This prevents salt and calcium from being stored within the kidneys – the accumulation of these components cause kidney stones to build up.
When we sweat more, we tend to drink more water in order to stay hydrated. Drinking water immensely benefits our health! We recommend checking our blog post “5 reasons why you should drink enough water” and make drinking enough water a regular habit in your life!
When you are experiencing pain, it can help to do some sweat producing exercises to lessen it. Physical activity affects our brain and makes the body produce serotonin, dopamine and noradrenaline amongst other chemicals; these compounds are naturally occurring neurotransmitters, which also have the capacity of easing pain within our bodies.
In our sweat are pheromones that have an impact on the mood and endocrine response – in other words, they improve relaxation. The brain is connected to the rest of our body through the spinal cord; this connection creates a communication system. When we feel the warmth on a physical level, the brain automatically receives signals, which make it establish a pleasant mood and a sense of well-being.
Perspiration is great for the immune system. The sweat layer on the skin slows down the growth of micro-organisms on the body surface. The PH value of sweat is slightly acidic; this makes it difficult for bacteria and fungus to spread there. Just another reason why sweat is so healthy.
Freshly formed sweat does actually not smell bad, only when bacteria on the skin get into the mix and start decomposing it into its separate components, a strong smell can be noticed. This should emphasise the importance of good personal hygiene and to pursue a healthy lifestyle, which should include a healthy nutrition as its foundation. There's a good amount of truth behind the following words: “You are what you eat.” So, don't try to avoid sweating, eat healthy foods, drink enough water and exercise regularly - good habits lead to a good life!
