In addition, heat can also cause dehydration, exhaustion, and heat stroke to the human when exposed to high temperatures for a long time.

To minimise the heat’s harmful health effects, doctors recommend the people to increase protective measures such as having sunscreen and sunglasses when going out, drink enough water and raise nutrition with lots of fruits to ensure enough vitamins to intensify the body's resistance.
