Avoiding heat hazards during summer months
Experts detailed how to stay safe as the summer heat intensifies.
Weather-related heat waves can pose a health risk to individuals, whether they plan to spend time indoors or outdoors, according to a news article from Outside. Although the outside temperature can provide basic information about the safety of venturing outdoors, the experts cited in the article stressed that individuals may also need to pay attention to their area’s heat index.
The heat index conveys how difficult it may be for the body to cool down and factors in humidity rather than just temperature. When the air temperature and relative humidity are higher, the heat index increases. The experts emphasized that this combination can be dangerous because sweat evaporation is the body’s primary mechanism for cooling down, and when humidity is higher, sweat fails to evaporate as easily. Heat indices in the yellow zones (caution and extreme caution) indicate a greater risk of fatigue, heat cramps and heat exhaustion during sustained physical activity, while indices in the orange (danger) or red (extreme danger) zones indicate dangerous conditions corresponding with confusion and heat stroke.
In addition to the heat index, the experts noted that wind and sun exposure can factor in how much hotter temperatures may feel. Full sun exposure without shade can increase the heat felt beyond the actual temperature, posing an even greater risk of adverse outcomes.
The experts recommended that individuals planning to spend time outdoors should stay hydrated with water and electrolytes, continually take breaks in air-conditioned or shaded environments before overheating sets in, place their arms in water to cool down more quickly, remove excess clothing that traps heat, pair a fan with mist or sprayed water, and remain indoors in dangerous heat index zones. Individuals who experience severe sweating, cramping, nausea, headaches or dizziness should immediately stop physical activity and seek a cooler climate.
