How does heat waves affect your body?

Heatwaves, or heat and hot weather that can last for several days, can have a significant impact on the bodily function.
As the body’s temperature increases, blood vessels also open up, leading to lower blood pressure.
The effects of lower blood pressure can be felt through dizziness, headache, and nausea.
To beat the heat, the body starts to sweat, leading to the loss of fluids and salt and, crucially, causing dehydration.
Dehydration can cause muscle cramps, confusion, and fainting. If the blood pressure drops too far, it can increase the risk of a heart attack.
