What You Need To Know When The Heat Index Rises This Summer
"Heat illnesses are a very large problem during the hottest summer months when people are outside performing tiring activities," said Dr. Bill Chase, MD with Iowa Health - Des Moines Physicians and Clinics. "Heat exhaustion occurs when the body is perspiring but the sweat can not evaporate due to humidity. Your body can not cool down and becomes overloaded."
Signs of heat exhaustion can include severe thirst, nausea, muscle weakness, irritability, headaches and increased sweating. If you begin to feel any of these symptoms, it is important to find shade immediately.
"When people ignore the signs of heat exhaustion, they are putting themselves in severe danger. Heat exhaustion untreated leads to heat stroke, which can be deadly. This occurs when the body stops controlling your body temperature and causes it to soar to 106 degrees or higher in 10-15 minutes," said Dr. Chase. "Heatstroke can lead to brain damage or even death if not treated immediately."
Signs of heatstroke include severe headaches, red, hot and dry skin, very little perspiration, confusion, unconsciousness, difficulty in breathing and a rapid pulse. If you are experiencing any of these symptoms you should call a doctor immediately.
"If you are experiencing heat exhaustion or heat stroke, there are a few things that can help to bring down your body temperature," said Dr. Chase. "Find shade immediately and get rid of any unnecessary clothing. Drink rehydration drinks such as sports drinks that contain electrolytes and spray yourself with cool water. You should rest for the next 24 hours and avoid strenuous activity for the next one to three days."
Iowa Health-Des Moines recommends these tips in preventing heat illnesses:
-- Always drink plenty of fluids before and during an activity in hot, sunny weather
-- Wear light-colored, loose-fitted clothing.
-- Do not take place in rigorous activity between the hours of noon and 6 p.m.
-- Pay attention and heed heat advisories and other weather broadcasts.
Enjoying the sunny weather is a great way to spend the summer, but be smart and drink plenty of fluids and come inside often. Staying safe in high temperatures is very simple; do not try to beat the heat.
