The UK Met Office has issued a rare 'extreme heat' alert for parts of England and Wales from Monday to Thursday, warning that adverse health effects are likely even for those not typically vulnerable to hot weather. In response, audiologist Kayleigh Waters from Boots Hearingcare has highlighted three major ways the heatwave can impact ear health: sunburn, swimmer's ear, and dehydration.
Sunburn and Tinnitus
Waters explained that sunburn can exacerbate tinnitus, a condition where individuals hear noises like ringing or buzzing without an external source. "Intense sun exposure often leads to inflammation, which is known for worsening tinnitus. Sunburn can also cause physical stress and dehydration, both factors that can heighten tinnitus symptoms," she said. To reduce risk, she recommends avoiding midday sun, wearing SPF, and using hats.
Swimmer's Ear Risk
As people seek cooling waters, trapped water in the ear can lead to swimmer's ear, an infection that may cause serious complications. Symptoms include tingling, fullness, muffled hearing, or partial hearing loss. If pain, itching, redness, or swelling develop, Waters advises consulting a doctor.
Dehydration and Inner Ear Function
Dehydration, common in high temperatures, affects the inner ear's hearing and balance systems. It can cause ringing in the ears, dizziness, or muffled hearing. Waters recommends increasing fluid intake to 8–10 glasses daily during warm periods, up from the NHS's standard 6–8 glasses. Those concerned about ear health can book a free hearing test at Boots Hearingcare or through the NHS.
