Many students spend their summers out of the heat.
Students who are used to the heat are less likely to have heat illness
Explanation:
Heat Acclimatization is simply the adaptation of the body according to the environmental conditions prevailing or happening around the body. For example, an organism may expose to cold weather, or hot weather, or humidity, or dusty environment, anything like this, then the organism's body adapts itself according to the environmental conditions. For example, if a person walks over the hills where oxygen level are less than the normal, the human body transports more oxygen in the blood than normal.
So heat acclimatization is important because in summer, many students remain in heat under the sun to play around, and due to this heat Acclimatization, their bodies adapt themselves according to the condition.

For example, the students who play sports and remain under the sun for longer hours in their daily routines, are also less likely to get ill because of the heat, as their bodies' acclimatization is already active and the bodies are already adapting according to the external environment.
