Summer Allergy Tips Make an Appointment Refer a Patient Ask a Question Reviewed by Carah B. Santos, MD (June 02, 2020) 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: Keep home and vehicle windows closed and use the air conditioner. Shower, wash your hair and change your clothing after coming in from outside. Stay indoors on windy days or wear a scarf or mask. Dogs or cats can bring pollen in from outdoors; bathe or wipe them down often. Do outdoor activities when pollen levels are low, usually early morning and early evening. Plan ahead and refill your allergy and asthma prescriptions before leaving on vacation. Know when the plants that trigger your allergies are pollinating or blooming. Time your vacation to coincide with low pollen levels. 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.
