As we come off a record-breaking heat wave with the hottest part of the summer still ahead, it’s crucial to learn how to handle the rising heat index to avoid potential health risks. High temperatures increase the risk of heat stroke, heat exhaustion, or severe sunburn. It’s important to recognize the signs early on, as symptoms like headaches or leg cramps can escalate quickly when exposed to scorching heat. Although seniors and babies are most at risk, anyone spending time outdoors can be affected by extreme temperatures and humidity.
What causes fatigue during hot weather?
Maintaining a normal body temperature requires a significant amount of energy, especially on hot days. The body works harder to cool down in extreme heat, leading to a feeling of tiredness and sluggishness. Additionally, many people are slightly dehydrated, and the combination of heat and sweat can worsen dehydration, resulting in fatigue.

How can you determine your heat tolerance?
Some individuals are more prone to heat-related issues than others. Elderly adults, for instance, are at a higher risk of heat stroke due to their bodies’ decreased ability to adapt to sudden temperature changes.
Furthermore, seniors are more likely to follow low-salt diets or take medications that can affect their response to high temperatures.
Medical professionals recommend that seniors stay hydrated more frequently during the summer months and limit their time outdoors.
What are the most effective cooling methods?
Various cooling techniques are available, but it’s essential to know which ones work best for you.
Cold drinks and ice can provide temporary relief from the heat. Spritzing yourself with cool water, fanning yourself with a paper, or standing in front of a fan can also help. Additionally, soaking your hands and feet, or using ice packs on specific areas like your cheeks, hands, feet, or neck can aid in cooling down.
What are the warning signs of heatstroke?
Humidity plays a significant role in heat stroke development, according to experts.
Heat stroke occurs when the body’s core temperature exceeds 104 degrees in adults and 105 degrees in children. It typically results from severe dehydration or the body’s inability to regulate temperature in extreme heat. Engaging in strenuous activities or spending extended periods in hot weather can increase the risk of heat stroke.
Outdoor activities in high temperatures that induce heavy sweating can lead to dehydration. Sweating releases minerals and salts that help maintain electrolyte balance in the body. As sweat loss increases, hydration becomes even more vital.
Avoiding alcohol, coffee, and caffeinated beverages during prolonged sun exposure is advisable, as they act as diuretics, expelling salt and water from the body. Opting for water after consuming these beverages can help maintain hydration levels.
Staying hydrated with water and consuming a salty snack, such as pretzels or chips, is the best way to combat dehydration. Avoid taking hot showers immediately after sweating, as it can lead to sodium loss and potentially result in fainting.
What are the indications of heat-related illnesses?
Heat-related illnesses manifest as a range of symptoms, starting with mild signs like rashes that can progress to muscle cramps due to dehydration.
Symptoms of heat exhaustion, a precursor to heat stroke, include heavy sweating, clammy skin, rapid pulse, dizziness, and headaches. If any of these signs are present, it’s crucial to stop the activity, find a cool place, and hydrate.
Heat stroke is the most severe heat-related illness and can lead to organ damage or death without immediate medical intervention. It can develop in just 10 to 20 minutes if the body temperature rises rapidly. Signs of heat stroke include nausea, vomiting, flushed skin, rapid breathing, increased heart rate, and potential loss of consciousness.
What should you do if you start feeling unwell?
Take breaks and ensure you stay hydrated, even before feeling thirsty, especially when exposed to prolonged sun exposure. Seniors are advised to maintain hydration levels throughout the day.
If someone displays symptoms of a heat-related illness, cooling them down with a wet cloth or ice bath to lower their body temperature is essential. Applying cold water or ice to the armpits or groin area, where major arteries are located close to the skin, can help. Encouraging the individual to sip sports drinks with electrolytes is also recommended.
Remember that hot cars can pose health risks as well, leading to fainting within just four minutes. It’s crucial to release some of the heat from the car before entering.
How can you prevent severe sunburn or sun blisters?
Using sunscreen with a higher SPF and reapplying it every few hours is crucial for protection. For deeper burns or blisters, washing with soapy water, applying petroleum jelly, and covering with a bandage can aid in healing. Avoid direct ice application and opt for cool compresses for relief. Aloe vera or zinc oxide creams are recommended for sunburns.
