For most parts of September, the heat index is computed to be a sweltering 38°C (100.4°F). Use additional protective measures, heat cramps and heat exhaustion are possible outcomes. Continuous activity might lead to heatstroke.Observations indicate that the heat index values are for shady locations with light wind. A rise in the heat index by 15 Fahrenheit (8 Celsius) degrees may result from direct sunlight exposure.
Note: The heat index, also known as 'real feel' or 'feels like', melds the effects of warmth and moisture to generate a feeling of heat. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. When you're directly under the sun's rays, remember that the heat index may surge by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Kids frequently ignore the importance of taking a break and rehydrating. Thirst is a late symptom of dehydration - thus, it is crucial to stay hydrated, especially during long-lasting physical activities.
One way the human body deals with excessive warmth is by perspiring and allowing sweat to evaporate. Relative humidity in excess curtails evaporation, therefore reducing heat dissipation from the body, leading to feelings of excess heat. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.
