Hay fever
Hay fever is an allergy that makes your body react to things in the air like pollen from grass and trees. It usually causes sneezing, itchy or watery eyes, and a blocked or runny nose, especially during spring and summer when pollen levels are high.

Allergies
Allergies occur when the immune system mistakenly reacts to harmless substances (allergens) like pollen, food, or dander, causing symptoms such as sneezing, itching, rashes, or hives. Common causes include dust mites, pets, nuts, and bee stings.

Allergy testing
Allergy testing helps find out what things your body is reacting to, such as certain foods, pollen, or chemicals. This can be done with a skin prick test or a blood test.
Antihistamines
Antihistamines are medicines that help ease allergy symptoms such as sneezing, itching, a runny nose, and hives. They work by blocking histamine, a chemical that causes these reactions in your body. Some can make you sleepy, while others are “non-drowsy” and don’t usually cause tiredness.

Asthma
Allergic asthma is a long-term condition where allergens such as pollen, pet hair, or dust can trigger swelling in the airways, making it hard to breathe and causing coughing or wheezing. It’s the most common type of asthma and often happens alongside hay fever or eczema.
