Heat index

The heat index value during May is calculated to be a sweltering 35°C (95°F). Take extra safety measures to prevent heat exhaustion and heat cramps. Heatstroke could follow lengthy activity.
It is essential to grasp that the heat index's numbers are for shade and light wind settings. Under direct sunshine, the heat index values might be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', shows a temperature sensation when both heat and moisture conditions are combined. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. Direct sunlight can potentially raise the heat index by 15 Fahrenheit (8 Celsius) degrees, so it's crucial to consider. Heat index values are especially vital to children. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
The primary way humans combat excessive warmth is by perspiring, letting sweat evaporate and cool the body. In circumstances of high air temperature and humidity (high heat index), the body's perspiration is restricted, heightening the feeling of warmth. Overheating and potential dehydration arise when body heat gain eclipses its release capability.
