While you’re enjoying outdoor activities and sunshine this summer, it’s important to take steps to keep yourself and your loved ones safe. Roughly 86 to 90% of skin cancer cases are linked to UV radiation from the sun, so wearing the right sunscreen is essential. Broad spectrum SPF 30 to 50 is ideal. “The thing you have to remember is to reapply your sunscreen every two hours, especially if you’re going to be outside for a long period of time,” said Dr. Elisee Dapeu, family medicine physician at EvergreenHealth Primary Care. Heat exhaustion is an early warning sign of heat stroke, a serious heat-related condition. Signs include nausea, vomiting, exhaustion and profuse sweating. “If you see somebody having those symptoms, or if you’re the one having those symptoms, it’s really important that you move from where it’s warm to a shaded area, remove any excessive clothing and drink plenty of water,” Dr. Dapeu said. Heat stroke happens when your body’s temperature rapidly increases, and it can be fatal. Signs include confusion, fainting and, in severe cases, seizures. If you suspect someone is having heat stroke, seek immediate treatment by calling 911 and cool the person down quickly by placing cold water or ice on the head, armpits and back of the neck. To avoid heat exhaustion and heat stroke, you need to stay hydrated. If you’re doing outdoor activities, Dr. Dapeu suggests drinking a cup of water every 15 to 20 minutes. Here are a few other tips for staying safe and enjoying summer: Pack an emergency summer bag. This can include sunscreen and protective clothing, like a hat. “You should have a first aid kit and bottles of water for sure,” Dr. Dapeu said. Make sure kids are wearing life jackets in the water and closely supervise them while swimming or boating. Enroll in a CPR class to help in cases of heat stroke or drowning. “Having that skill is really, really useful and valuable, not only for your loved ones, but also for people outside,” Dr. Dapeu said. To book a summer check-up and learn more safety tips, schedule an appointment with a primary care provider on the EvergreenHealth website.
