Dear MEL Topic Readers,
What does hot weather do to the body?
It’s summer in the northern hemisphere. Summer is becoming longer and more severe with higher temperatures and heat waves of over 40 °C. Can our bodies withstand such heat? Our bodies function best at a core temperature of about 37 °C. When the outside temperature rises, our bodies try to regulate body temperature by opening up blood vessels, which leads to lower blood pressure and makes the heart work harder to pump blood throughout the body. Also, as we sweat, our bodies lose fluids and salt disproportionally, so that their balance changes. As a result, we may feel dizziness, nausea, fainting, muscle cramps, and or headaches, typical symptoms of heat exhaustion. If you feel any of such symptoms in the heat, you should cool your body and skin, lie down, drink a lot of water or rehydration drinks. But if someone doesn’t recover from heat exhaustion within half an hour, feels confused or nauseous, vomits, stops sweating, experiences a high temperature over 40°C, or loses consciousness, the person is likely suffering from heatstroke and needs medical emergency. Since the climate is changing faster than how much our bodies can adapt, we need to adapt our lifestyles and activities to the heat.
