Note: The heat index, also known as 'apparent temperature' or 'feels like', is a fusion of air temperature and moisture levels to demonstrate the sensation of heat.

Children often fail to understand the importance of rest and rehydration. Thirst is a late manifestation of dehydration - hence, it is crucial to stay hydrated, especially during ongoing physical activities.
One of the main methods the human body employs to cool down is by perspiring, as this process allows sweat to evaporate and remove excess heat. In the presence of high relative humidity, the evaporation rate diminishes, resulting in the body retaining more warmth compared to dry conditions. As the body accumulates more heat than it can release, body temperature goes up, increasing the risk of heat-related health issues.
