It’s the month of June and summer is at its peak. We are all sweating it out outdoors and turning up our ACs indoors. But understanding what’s happening to our body and how we can keep it cool is important. A quick understanding of atmospheric temperature and body temperature will help you get your list of foolproof ways of keeping cool in the scorching hot summer.
Room Temperature VS Body Temperature
Have you ever thought why a bowl of hot water and a bowl of cold water both eventually come to room temperature? It’s because heat naturally flows from warm to cool places. So there is a constant flow of energy in the atmosphere where everything is trying to reach a state of equilibrium in temperature.
But our body is slightly different. It constantly produces more heat so it needs to escape that heat through the skin into a colder environment. The greater the temperature difference the faster will be the process of cooling.
So How Do You Keep Cool?
Simple daily practices can help you get through the heat wave. Most of know us them but are not sure how they work on us. So let’s briefly understand these simple techniques that keep us cool. The science is simpler but very effective.
Sweat It Out!
Depending on the humidity levels around you this could either make you feel hotter or cooler. Sweating is our body’s natural way of releasing excess heat from the body. When you sweat there is an increase in blood flow to the skin, hands and feet to transfer heat to the surface. This heat is then taken away by evaporation of the sweat leaving the surface of our body cool. So don’t wipe off that sweat!
Replenish What You lose!
Sweating helps cool you down but it also makes you lose the water in your body. So it’s important to regularly hydrate yourself. Depending on how much you sweat you should increase your consumption of water in summers. Dehydration can cause a lot of problems in your daily functioning and also cause kidney diseases. A bottle of water in your backpack should keep you away from all these worries.
Head For The Green Shade!
Keeping indoors when the heat wave is action is a wise choice. But if you don’t have one you should try to keep yourself around greenery. Plants are like natural air conditioners that not only block heat but also keep the temperature around it cool. This is because of evaporative cooling. The plants absorb the moisture from the soil and release it through the leaves. This allows the air temperature to be a few degrees cooler.
Go Light and Loose!
We are often told that one should not wear black during summers but how well do we understand why? It’s because all things have an ‘albedo’. It is its reflective ability. So when the sun hits the surface the reflective ability of the thing will determine how hot it gets. More albedo = less heat absorbed and more turned away. So black is low on albedo so we should wear colours that reflect more light and keep it loose to allow perspiration.
