Is Global Warming Making Your Allergies Worse?

By: Margaret L. Co, M.D., Director of Allergy and Immunology, The Valley Hospital

Global warming and climate change are in the headlines today.  For allergy sufferers, the impact of warmer temperatures on their daily lives may soon become very apparent.  If you think that your spring allergies have worsened, you may be right, and global warming may have contributed to this.  With this year’s winter being warmer than usual (temperatures this year were the second highest in history for the month of February), the pollen season is most likely going to be early.  In the Garden State, the tree pollen count will surely be one of the highest in the nation.

Seasonal allergic rhinitis, or hay fever, affects 35 million Americans.  Symptoms include sneezing, a stuffy or a runny nose, and itchy, watery eyes.   Many also experience seasonal asthma manifested by a cough, wheezing and difficulty breathing.  Allergies can significantly impact the quality of life by disrupting sleep and affecting learning ability at school and productivity at work.

Although pollen can be difficult to avoid entirely, these tips will help you to enjoy the spring:

  • 2. Better yet, monitor pollen counts so that you know when to limit your exposure outdoors. Pollen COUNTS are different from pollen FORECASTS, which are based on current weather conditions and the previous year’s pollen counts.  Pollen counts are performed by counting stations located throughout the United States and are required to meet stringent certification standards.  The National Allergy Bureau (NAB) provides the most accurate and reliable pollen and mold levels.
  • 3. Sign up for free email alerts by visiting from your smartphone and adding the app to your home screen.
  • 4. Keep your windows at home closed and use air conditioning if possible.  Also keep car windows closed and use the recirculate option for air conditioning.
  • 5. Take a shower after spending the day outside to remove pollen from your hair and skin.  When outdoors, wear sunglasses and a wide-brim hat to reduce pollen blowing into your eyes.
  • 6. Take your medications at the start of, or even before, the pollen season and take them regularly throughout the season, especially if your allergies tend to be severe.
  • 7. For long-term relief of allergy symptoms, talk to your allergist/immunologist about immunotherapy (allergy shots).  This is a proven treatment approach that provides lasting benefits for many people suffering from allergic rhinitis.  Sublingual immunotherapy (allergens in tablet form administered daily under the tongue at home) is another form of allergy immunotherapy that is available by prescription for patients with certain allergies who do not want to get injections.
