Climate change is prolonging allergy season, B.C. doctors say
Seasonal allergies are a common issue for many people, causing symptoms such as itchy eyes, runny nose, congestion, and sneezing. Dr. Angeliki Barlas, an allergist in Port Moody, B.C., believes that climate change is exacerbating these symptoms and prolonging allergy seasons.
According to Dr. Barlas, the warming of the environment due to climate change is causing pollen to become more inflammatory, impacting the immune system more severely. This results in longer and more intense allergy seasons, with many individuals feeling like they are suffering almost year-round.
Dr. Davidicus Wong, a family doctor in Burnaby, also acknowledges the role of climate change in worsening allergy symptoms. He explains that with a warmer climate, pollinators are being tricked into pollinating early, leading to increased pollen levels in the air.
As the president of the B.C. Society of Allergy and Clinical Immunology, Dr. Barlas emphasizes the importance of environmental control in preventing allergy symptoms during high pollen season. This includes closing windows to prevent pollen buildup, showering and washing clothes after outdoor activities to remove pollen, and avoiding exposure to air pollutants like wildfire smoke.
When it comes to medication, Dr. Barlas recommends staying away from Benadryl due to potential long-term negative effects such as memory loss and dementia. Instead, non-drowsy antihistamines like Claritin or Allegra are preferred for treating allergy symptoms.
For allergy patients interested in immunotherapy, a desensitization treatment for allergies, Dr. Barlas suggests seeking a referral from a primary healthcare provider. While there are no allergists in northern B.C., patients can access online appointments with allergists in the Lower Mainland through telehealth services.
Overall, it is clear that climate change is playing a significant role in exacerbating allergy symptoms and prolonging allergy seasons. By taking steps to control the environment and using appropriate medication, individuals can better manage their allergies and improve their quality of life.
