Continuous activity could result in heatstroke.Be informed that the heat index values are oriented around shady conditions and gentle breezes.

Note: The heat index, also known as 'real feel' or 'felt air temperature', is an estimation of the warmth sensation when considering humidity levels. The influence of weather is personal, with a diverse population experiencing it differently due to differences in body mass, stature, and degree of activity. Awareness is key; direct sunlight can enhance the weather's impact, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Children often overlook the need for breaks and fluid intake. Thirst is a late-stage sign of dehydration - hence, it is necessary to stay hydrated, especially during extended periods of physical activities.
Sweat evaporation, driven by perspiration, is the method the human body uses to rid itself of excessive warmth. Under conditions of increased relative humidity, the evaporation rate lessens, causing the body to retain more heat than under less humid conditions. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.
