London's parks, once lush and green, have transformed into barren, yellow wastelands due to the ongoing heatwave. Stepping onto the grass kicks up clouds of dirt, and a dust devil recently made headlines in Greenwich Park. However, the parks aren't the only victims—sitting in these dry areas could harm your health. Doctors suggest wearing a face mask to protect against inhaling dust, similar to measures taken during the Covid pandemic.
Health Risks of Dust Exposure
Dr Crystal Wyllie told Metro that dusty environments can irritate airways and trigger an immune response, causing airway muscles to tighten, swell, and increase mucus production. Breathing in fine particles can irritate the eyes, nose, throat, and lungs, leading to coughing, wheezing, chest tightness, and shortness of breath. Eyes may water and itch, and skin can become irritated.
Those with sensitive airways, such as people with asthma or COPD (Chronic Obstructive Pulmonary Disease), are highly vulnerable. Dust exposure can spark severe asthma attacks and wheezing. Dry, windy conditions, combined with large crowds moving across bare ground, increase the amount of dust in the air. Australia's National Asthma Council warns that the longer you're exposed, the greater the chance of symptoms. Carrying an inhaler when leaving the house is advisable, especially for park visits.
Prevention and Mask-Wearing
Dr Wyllie recommends wearing a mask to protect lungs from airborne particles, especially for those at higher risk. Face masks were mandatory in the UK from June 2020 for two years due to Covid, and while some continue to wear them, others find them irksome. One Reddit user expressed dislike for the sensory experience, while another noted that despite pandemic fatigue, masks are a useful habit. Staying hydrated is also essential to keep throat linings moist and help clear mucus.
If you experience breathing difficulties, consult a doctor or seek emergency care if severe.
