Top Tips for Managing Hay Fever During Ireland’s Pollen Season

As temperatures across Ireland are forecast to rise in the coming days, health experts are warning of an anticipated increase in cases of polymorphic light eruption (PLE), a common skin condition triggered by sunlight that affects thousands of people each spring, and summer. Often referred to as “sun allergy” or “sunny weather rash,” PLE typically appears within hours or days of first significant sun exposure after winter months, causing itchy, red, raised patches or blisters on areas of skin that have been covered during colder seasons.

The Irish Sun reported that dermatologists are advising the public to take preventive measures as UV levels begin to climb, particularly for those with a history of the condition. PLE is estimated to affect up to 20% of the population in Northern Europe, with women aged 20 to 40 being most commonly affected. While not life-threatening, the condition can cause significant discomfort and disrupt daily activities during periods of increased outdoor exposure.

According to the British Association of Dermatologists, PLE occurs when the skin’s immune system reacts abnormally to ultraviolet (UVA) radiation, leading to inflammation. Unlike sunburn, which results from direct DNA damage by UVB rays, PLE is an immunological response that can occur even with sunscreen use if UVA protection is inadequate. Symptoms usually appear on the forearms, hands, chest, and legs — areas that are typically covered in winter but exposed in spring — and may last up to two weeks if further sun exposure is avoided.

Medical professionals emphasize that gradual acclimatization to sunlight is one of the most effective strategies for preventing flare-ups. The Irish Skin Foundation recommends starting with short periods of sun exposure — just a few minutes a day — and gradually increasing time outdoors over two to three weeks to allow the skin to build tolerance. This process, known as hardening, can significantly reduce the severity or occurrence of PLE in susceptible individuals.

In addition to gradual exposure, experts advise using broad-spectrum sunscreens that protect against both UVA and UVB rays, with a minimum SPF of 30 and a high UVA protection rating (indicated by the UVA circle logo or a four- or five-star rating in the UK/Ireland system). Sunscreen should be applied 15 to 30 minutes before going outside and reapplied every two hours, or after swimming or sweating. Wearing protective clothing, such as long-sleeved shirts and wide-brimmed hats, and seeking shade during peak UV hours (11 a.m. To 3 p.m.) are also strongly recommended.

For those who develop symptoms, over-the-counter treatments such as antihistamines can help relieve itching, while topical corticosteroids may reduce inflammation in more pronounced cases. In instances where PLE recurs severely or impacts quality of life, dermatologists may recommend phototherapy — controlled exposure to ultraviolet light under medical supervision — to desensitize the skin before the summer season begins.

Meanwhile, allergists caution that the current rise in temperatures may also be exacerbating seasonal allergies, creating a “perfect storm” for individuals sensitive to both environmental triggers. RSVP Live reported that a medical expert warned of elevated pollen levels due to favorable weather conditions, advising allergy sufferers to keep windows closed during high-pollen periods and to use air filtration systems indoors to reduce exposure.

While PLE and pollen allergies are distinct conditions, their concurrent occurrence can compound discomfort for affected individuals. Health officials stress the importance of distinguishing between the two: PLE presents as a localized skin reaction to sunlight, whereas allergic rhinitis involves sneezing, nasal congestion, and itchy eyes triggered by airborne allergens. Proper identification allows for appropriate management — sun protection and skin care for PLE, and allergen avoidance or antihistamines for pollen sensitivity.

There is currently no known cure for PLE, but most individuals find that symptoms become less severe with repeated springtime exposure over several years. Researchers continue to study the underlying immune mechanisms involved, with some investigations exploring the role of genetic predisposition and oxidative stress in the skin’s response to UVA. Public health messaging remains focused on prevention, early recognition, and safe sun habits as the most effective tools for managing the condition.

As Ireland transitions into warmer weather, health authorities encourage the public to remain vigilant about skin protection and to consult a general practitioner or dermatologist if they experience unusual or persistent skin reactions after sun exposure. With proper precautions, many people can enjoy the spring and summer months while minimizing the impact of this common but manageable photosensitive condition.
