Britain is anticipating a significant increase in hay fever symptoms this week, with record-breaking June temperatures potentially reaching 38C (100.4F). This surge in heat, combined with high pollen levels, is being described by experts as a 'pollen bomb,' which could trigger debilitating allergic reactions for the estimated 13 million hay fever sufferers in the UK.
Hay fever, an incurable allergic condition, can manifest with symptoms such as headaches, fatigue, sneezing, coughing, nasal congestion, and itchy or sore eyes and throats. The current weather conditions are creating a perfect storm for amplified allergic responses. Experts note that the fluctuating weather patterns this summer have caused pollen from trees and grasses, which typically release their allergens at different times, to overlap. This overlap results in higher concentrations of pollen particles in the air.
Medical Interventions for Hay Fever
Medical professionals suggest a multi-faceted approach to managing severe hay fever symptoms. Professor Adam Fox, a pediatric allergist, recommends a combination of regular antihistamine use and nasal steroid sprays. He stated that this regimen is safe and can significantly improve symptoms for a majority of patients. Fexofenadine is cited as a preferred antihistamine due to its reported lower incidence of drowsy side effects compared to alternatives like chlorphenamine (found in Piriton). Other non-drowsy options include loratadine and cetirizine hydrochloride.
Nasal corticosteroids, which reduce inflammation in the nasal passages, are another recommended treatment. While they typically take about a week to become effective, prescribed steroids like prednisolone may offer faster relief for more severe cases. Decongestants can also alleviate nasal blockages by reducing swelling in blood vessels, but their use is advised for no more than a day or two due to potential for dependency.
Leukotriene modifiers, drugs commonly used for asthma, can be employed to block chemicals involved in allergic reactions and are sometimes used for particularly severe hay fever. However, these are generally reserved for patients whose symptoms persist despite other treatments, including immunotherapy. Immunotherapy, a longer-term treatment, gradually trains the immune system to tolerate pollen.
Non-Pharmacological and Lifestyle Adjustments
Beyond medication, several other strategies can help mitigate hay fever symptoms. Nasal rinses, using a saline solution to flush pollen from the nasal passages, are considered beneficial. This method involves irrigating the nose with a warm salt-water mixture, which is then expelled through the mouth, carrying away pollen particles. Ready-made kits are available for this purpose.
Other promising, though less conventional, methods include light therapy, which uses infrared light to reduce nasal inflammation, and ectoin sprays. Ectoin sprays, similar to the NHS recommendation of applying petroleum jelly around the nostrils, act as a barrier to prevent pollen from entering the nasal passages.
Dietary considerations are also mentioned, with quercetin, an antioxidant found in foods like apples and onions, being studied for potential antihistamine effects, though it is not considered an official treatment. Lifestyle adjustments recommended by experts include using air purifiers in homes to remove airborne pollen, and for pet owners, wiping down animals after walks to prevent pollen from being carried indoors.
The NHS advises applying a thin layer of petroleum jelly around the nostrils to trap pollen. Wearing wraparound sunglasses, face masks, or wide-brimmed hats can also reduce exposure. Showering after spending time outdoors, keeping windows and doors closed, vacuuming regularly, and wiping down surfaces can further minimize pollen contact. Avoiding activities that increase pollen exposure, such as walking through grass or spending prolonged periods outdoors, is also recommended. Keeping fresh flowers indoors and drying clothes outside are noted as potential triggers.
Pharmacists can provide guidance on appropriate treatments, including antihistamines, nasal sprays, and eye drops.
