After experiencing a record-breaking heat wave and with the hottest part of the summer still ahead, it’s crucial to learn the dos and don’ts as the heat index continues to rise. The potential health consequences of ignoring the rising temperatures include heat stroke, heat exhaustion, or severe sunburn. Symptoms like headaches or leg cramps can quickly escalate when the body temperature rises in the scorching heat. While seniors and babies are most at risk, anyone spending time outdoors can be affected by the high temperatures and brutal humidity.
What causes fatigue in extreme heat?
Maintaining a normal body temperature requires a significant amount of energy. When the temperature rises, the body works harder to cool down, leading to feelings of tiredness and sluggishness. Dehydration is also a contributing factor, as many people are already slightly dehydrated in their daily lives. Being hot and sweaty exacerbates dehydration, with fatigue being a common symptom.

How can you determine your heat tolerance?
Some individuals are more susceptible to heat-related issues than others. Older adults are particularly at risk for heat stroke due to their bodies’ reduced ability to adapt to sudden temperature changes.
Seniors are often on low-salt diets or taking medications that affect their responses to high temperatures, making them more vulnerable. It’s recommended that seniors stay hydrated throughout the summer months and limit outdoor activities.
What are effective ways to cool down?
Various methods can help cool you down, with some being more effective than others. Cold beverages and ice can provide temporary relief, while spritzing yourself with cool water, using a fan, soaking your hands and feet, or using ice packs can also help regulate body temperature.
How can you recognize the signs of heatstroke?
Heatstroke is more likely to occur in humid environments, with core body temperatures exceeding 104 degrees in adults. Prolonged exposure to extreme temperatures or intense physical activity can lead to heatstroke. Heavy sweating can cause dehydration, emphasizing the importance of staying hydrated.
Avoiding alcohol, coffee, and caffeinated beverages can help prevent dehydration in the sun. Hydrating with water and consuming salty snacks when sweating heavily is essential. Recognizing the signs of heat-related illnesses, such as heat exhaustion and heat stroke, and taking immediate action is crucial to prevent serious health consequences.
Take breaks regularly, stay hydrated, and seek shade if feeling unwell due to heat. If someone exhibits signs of heat-related illness, cooling measures should be implemented immediately to lower body temperature. Avoid prolonged exposure to hot cars, as they can also pose health risks.
