USET Tribal Epidemiology Center (USET TEC) on Heat Index and Health
Heat-related illnesses, such as heat exhaustion and heat stroke, occur when the body is unable to cool itself properly. Sweating is the normal method of cooling, but in extreme heat, this process may be ineffective. This can lead to stress and damage to the brain and vital organs, and in some unfortunate cases, extreme and life-threatening complications can occur.
Some individuals are more at risk during high heat events than others and include outside workers, infants and young children, the elderly, and those with chronic conditions. However, days with a heat index over 90°F can be dangerous for anyone. In addition, Tribal Nation members in cooler climates may be less prepared for high heat indexes. To beat the heat, USET TEC recommends:
- Stay hydrated by drinking plenty of water.
- Limit outdoor activity, especially midday when the temperatures are highest.
- If going outside, limit time outdoors and wear a hat, sunscreen, and lightweight, loose-fitting clothing.
- Find air-conditioned buildings or public areas to cool off (see nearby cooling centers)
- Create makeshift AC units for housing without AC (see examples)
- Purchase cooling blankets. For pets, cooling blankets and ice water are recommended.
