Summer Allergy Tips Make an Appointment Refer a Patient Ask a Question Reviewed by Carah B. Santos, MD (November 01, 2016) Allergies can spoil summer fun and vacations, but they can be prevented. The biggest culprits that cause allergy symptoms during the summer months are grass and weed pollens. Here are a few tips for living with summer allergies and reducing the misery from pollen allergies when you travel: Find out which plants will be pollinating where you will be traveling. For example, Hawaii has grass pollination year-round. Southern states typically have the longest pollination period; grasses pollinate 10-11 months of the year in these regions. Know when the plants that trigger your allergies are in bloom, and avoid visiting at that time of year. Time your trip to coincide with low levels of pollen. If traveling by car, keep the windows closed, and use the air conditioner. After returning from outdoors, shower, wash your hair and change your clothing. Plan ahead, and fill your allergy and asthma prescriptions before leaving home. If you have a severe allergy to bees, wasps, hornets, fire ants and other insects, wear long sleeves, pants and socks when outdoors, and be careful near outdoor garbage cans, where yellow jackets often congregate.
