As temperatures rise and spring season starts to approach, more people will find themselves having symptoms like runny nose, sneezing, and itchy/watery eyes. These are due to the allergic reaction with the various types of spring pollen that is in the air and the environment. The most common types of pollen that cause these reactions are from trees, grass, and weeds.Trees such as birch, hickory, pine, oak, elm, and sycamore are some of the most common pollen allergies. Grasses like bermuda and timothy often give people allergy troubles. If you plan on being outside in the spring, try and avoid such plants to reduce your pollen exposure. In addition, using a HEPPA filter in your home and shutting your windows to decrease your inside pollen count can help you sleep better at night.
