Note: The heat index, also known as 'apparent temperature' or 'feels like', unifies temperature and humidity readings to offer a comprehensive feel of warmth. The impact of weather is individual, with diverse individuals experiencing it differently due to variations in body mass, height, and activity levels. Direct sun exposure is noteworthy in its ability to escalate the felt temperature, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are quite important for children. Children often fail to recognize the requirement to rest and rehydrate. Thirst, being a late symptom of dehydration, underlines the importance of maintaining hydration, especially during ongoing physical activities.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. An increase in relative humidity hinders the body's normal cooling function by reducing evaporation, thereby decreasing the rate of body cooling and enhancing the sense of warmth. If the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.

Adopt measures and apply sun safety strategies. Shielding from skin and eye damage is necessary. Attempt to stay under shade and limit exposure to the Sun between 10 a.m. and 4 p.m., when UV radiation is at its peak. Remember, devices such as parasols or canopies might not provide complete sun protection. A wide-brimmed hat is a staple for defending the face, eyes, ears, and neck from the Sun.
