💭 Warm-Up Question
How do you stay cool when the weather is very hot where you live?
📖 Short Reading
High temperatures can affect our health in many ways. When it is very hot, people can feel tired, thirsty, or dizzy. Heat can cause problems like heat exhaustion or heatstroke, especially for older people and children. Some causes of health problems in hot weather are not drinking enough water, being outside too long, or living in a hot house without proper cooling. In many places, cities can become hotter because of buildings and roads that absorb heat. This is called the heat island effect. To stay safe, people can drink water often, wear light clothes, and avoid too much sun. Using fans or shade helps cool down the body. Communities can plant trees to give shade and reduce heat. It is important to know the signs of heat problems and act early. By managing heat carefully, we can protect our health during hot days.
