Extreme heat is getting more common around the world due to climate change and global warming. The high temperatures, which sometimes exceed 40 degrees Celsius, have serious consequences for human health as they can seriously affect the brain and body.
As known, human body is set to regulate its temperature keeping it around 37 degrees Celsius. However, extreme heat can damage this thermoregulatory mechanism. The main problem with exposure to high temperatures is dehydration. When we sweat, we lose water and electrolytes, which can lead to serious heart and blood circulation problems. This, in turn, can also affect the brain.
How Does Extreme Heat Affect Our Brain and Body?
Brain is extremely sensitive to changes in temperature and dehydration. Extreme heat can lead to lethargy, attention deficit and affect our cognitive function. Serious problems such as heat stroke and hyperthermia can even occur, which can be fatal.
Further, heat can increase the risk of various diseases, such as cardiovascular diseases and stroke. They disrupt normal circulation and cause increased blood pressure, which can affect the brain and nervous system.
To protect ourselves from the harm of extreme heat, we should take enough liquid, wear light and fair-coloured clothes, avoid straining our body during the heat peaks and seek a cool place if needed.
In conclusion, extreme heat poses a serious threat to human health affecting both brain and body. We are advised to be careful and cautious, especially in conditions of hot summer days, to avoid serious health problems.
