The National Health Service (NHS) has issued a simple grass rule for hay fever sufferers as parts of the United Kingdom prepare for “very high” pollen levels this week. The guidance advises individuals to avoid cutting grass or walking on grass when the pollen count is elevated, a measure that can significantly reduce exposure to allergens.
Hay Fever Prevalence and Symptoms
Hay fever, medically known as allergic rhinitis, affects approximately one in four people in Britain, equating to around 16 million individuals. The condition triggers symptoms such as sneezing, coughing, and itchy eyes due to reactions to pollen, dust, mould, and mites. While there is no known cure, treatments and precautions can alleviate symptoms.
The NHS lists key indicators of hay fever to watch for: sneezing and coughing; a runny or blocked nose; itchy, red, or watery eyes; itchy throat, mouth, nose, and ears; loss of smell; pain around the sides of the head and forehead; headache; and fatigue. Symptoms typically worsen between late March and September, especially in warm, humid, and windy conditions when pollen counts peak.
Forecasted Pollen Levels
According to the Met Office, several regions will experience “very high” or “high” pollen counts this week. On Tuesday, June 30, the east of England and east Midlands face “very high” levels, while London, south east England, south west England, the west midlands, Yorkshire and Humber, north west England, and north east England see “high” levels. On Wednesday, July 1, and Thursday, July 2, only London and south east England are forecast for “very high” counts. By Friday and Saturday, London, south east England, and the east of England will experience “very high” pollen levels.
NHS Recommendations for Prevention and Treatment
Beyond the grass rule, the NHS offers additional advice to minimise hay fever symptoms. Individuals are urged to apply petroleum jelly (such as Vaseline) around the nostrils to trap pollen, wear wraparound sunglasses, a mask, or a wide-brimmed hat to prevent pollen from entering the nose and eyes, and shower and change clothes after being outdoors to wash off pollen. Keeping windows and doors shut, vacuuming regularly with a damp cloth, and using a pollen filter in car air vents or a HEPA filter in vacuum cleaners are also recommended.
Actions to avoid include spending excessive time outside, keeping fresh flowers indoors, smoking or being around smoke, drying clothes outdoors (as they can catch pollen), and allowing pets indoors if possible (since they can carry pollen). The NHS also advises consulting a pharmacist about medications such as antihistamine drops, tablets, nasal sprays, and steroid nasal sprays.
The NHS clarifies that hay fever can persist for weeks or months, unlike a cold, which typically resolves in one to two weeks. By following these guidelines, sufferers can better manage their symptoms during periods of high pollen.
