Hayfever is a prevalent allergy triggered by pollen, causing symptoms like sneezing, coughing, and itchy eyes. The NHS notes that symptoms are most severe from late March to September, especially in warm and humid conditions when pollen counts are high. While there is no cure, the NHS recommends several strategies to alleviate symptoms. These include applying petroleum jelly around the nostrils to trap pollen, wearing wraparound sunglasses and a wide-brimmed hat, and showering and changing clothes after being outdoors to remove pollen. Additionally, keeping windows shut, vacuuming regularly, and using HEPA filters in vacuums can help reduce exposure. The NHS advises against activities like cutting grass, spending excessive time outdoors, and keeping fresh flowers indoors, as these can exacerbate symptoms. If symptoms persist or worsen, individuals should consult their GP for potential steroid treatments or immunotherapy options.
