A ‘prolonged, dangerous heatwave’ is sweeping across the central and eastern United States, just hours ahead of the Fourth of July holiday. The temperature is expected to go up to 105 degrees Fahrenheit 40.5 degrees Celsius), According to the National Weather Service. The soaring temperatures are raising concerns as US President Donald Trump hosts a celebration marking America’s 250th birthday and multiple World Cup matches take place outdoors.In the United States, hundreds of people die due to heat-related illness. A heatstroke can cause permanent disability or death if the person does not receive emergency treatment, according to the CDC. As the extreme conditions are likely to persist through the festive weekend, it is important to follow some safety guidelines, especially if you are going outside in the heat.
Evaluate heat conditions before you step outside
Before you head out, check for the warnings in your area, issued by the National Weather Service. Heat illness symptoms can vary by person, Bharat Venkat, director of the University of California, Los Angeles Heat Lab, told AP. The risk of heatwave depends upon each person’s tolerance, how acclimated to heat you are, and the duration of exposure. So, an absolute temperature at which the heat becomes dangerous cannot be said. The humidity also plays a role. If it’s a very humid day and there’s no wind, then you may be at higher risk, even though the air temperature is lower.
Pre-hydrate and re-hydrate
If you are spending time outdoors, it is important to pre-hydrate. “Grab a glass of water or a sports drink before you head out to the outdoors,” Momin of Memorial Herman Health System told NPR. Neil Gandhi, a physician at Houston Methodist Hospital, stressed the importance of carrying plenty of water as you step outside. He suggests sipping water throughout the day. Don’t wait until you feel thirsty. “The moment you begin to feel thirsty, you’re likely anywhere between 10 to 25% dehydrated already,” the doctor said.Water is the best fluid for hydration. In normal circumstances, there is no need for electrolytes. You can save them for activities that require physical effort or if you are sweating a lot. UNICEF suggests drinking water at regular intervals and carrying a water bottle as you step outside.
Higher-risk individuals should take extra care
Though a heatwave can affect anyone, some people are more vulnerable than others. People aged 65 or above, babies and young children under the age of 5, and pregnant women are at increased risk, according to the NHS. Those with long-term conditions such as heart problems, breathing problems, dementia, diabetes, kidney disease, Parkinson’s disease, mobility problems, mental health problems, or drug or alcohol addiction are also at high risk. People taking multiple medications should also take extra care. If you are already ill or dehydrated from diarrhea and vomiting, you should also stay alert. Those who engage in manual labour should also take extreme care.
Be aware of the symptoms
Heat-related illnesses can be serious and even life-threatening. A heat stroke is the most serious condition, according to the CDC. This happens when the body can no longer control the temperature. The body temperature can rise up to 106°F or higher within 10 to 15 minutes of a heat stroke. So it is important to know the symptoms. Confusion, altered mental status, slurred speech, loss of consciousness, seizure, high body temperature, hot, dry skin, or profuse sweating are the symptoms of heat stroke. It can be fatal if treatment is delayed.Heat exhaustion is caused by excessive loss of water and salt due to sweating. People may experience headache, nausea, dizziness, weakness, thirst, heavy sweating, and high body temperature.
Wear protective clothing
When you step out in the sun, it is important to protect your skin. Wear lightweight clothing that blocks the sun. Loose-fitting clothes are best during this hot summer weather. Avoid anything too tight, as it traps sweat. Feel free to wear a hat and apply sunscreen to protect your skin from dangerous UV light. If possible, get yourself a portable handheld fan, or a cooling vest.Following these simple steps may help you stay safe and still enjoy the festive weekend.
