The arrival of fine weather and milder temperatures marks the return of respiratory allergies.

These allergies consist of unsuitable or excessive immune system reactions of the human body when it comes into contact with a foreign substance known as an allergen. Generally, respiratory allergies take two forms: allergic rhinitis and allergic asthma. Each of these conditions are characterised by very particular symptoms.

People who are allergic should adopt certain reflexes to improve their daily lives and thus reduce the frequency of the symptoms.
