Summer is often marked by vacations, recreational events and relaxing moments spent by the pool or on the beach. But when the weather heats up, so can potential health hazards that can ruin all of the fun. The following are some of the more common summertime ailments and how to avoid them.

• Lawn and garden injuries: Lawn and garden injuries may not be common, but men, women and children should exercise caution when using lawn and garden equipment. Wear protective shoes and gloves and safety goggles. Remember to turn off any motorized tools before attempting to repair or unclog the blades.

• Swimmer’s ear: Water that remains in the ear canal after swimming can make the ear a breeding ground for swimmer’s ear, which is a bacterial infection. If water remains in your ear for more than one night, visit an ear, nose and throat specialist.

• Insect bites and stings: Insects return when temperatures rise. Mosquitoes may be the biggest nuisance, but biting flies and wasps also make formidable foes. Use insect repellent to keep the bugs away. Wear long pants and check for ticks after hiking.

• Boating accidents: Many boating accidents can be attributed to inexperience with the vessel and failure to take proper safety precautions on the water. Make sure everyone on the boat wears a life jacket, and follow proper boating protocol throughout your trip.

• Dehydration: The body needs extra water on hot days, especially when spending ample time outdoors. Dehydration can cause dizziness and dry mouth and may make you feel faint. Always drink plenty of water and avoid alcoholic beverages and soft drinks, which can contribute to dehydration when consumed in excess.
