Heat index values are extremely significant for babies and toddlers. Young ones often disregard the necessity to rest and hydrate. Thirst usually indicates advanced dehydration - hence, it is key to stay hydrated, particularly during ongoing physical activities.
Perspiration, followed by sweat evaporation, is the human body's chief method to maintain a balanced temperature. When the air holds a significant amount of moisture, the efficiency of the evaporation process is decreased, preventing the body from cooling down efficiently, leading to the sensation of overheating. When body heat isn't effectively managed, risks of dehydration and overheating amplify.
