Why are we allergic to trees?
Allergy to tree is an inappropriate response of the immune system in the presence of tree pollen. Earlier this year, the trees prepare for their reproduction. They are covered with pollen-carrying male seed. The tree pollen is wind-pollinated, they are transported by the wind until the corresponding female. But, as this mode of transport is not very precise, the amount of pollen emitted must be substantial to encourage pollination. In addition, wind-pollinated pollen are particularly light, thin and smooth. So, during the pollination period, the risk of inhaling a tree pollen is very strong. This substance foreign to the body will be identified by the immune system. And if the person has an allergic, it may trigger an allergic reaction.The symptoms of allergy to tree
Allergy to tree manifested by seasonal allergic rhinitis, also known as hay fever. Symptoms then every year the same season. Generally, runny nose and itchy. It can also be blocked. The allergic reaction may cause bursts of sneezing. If the pollen comes into contact with eyes, conjunctivitis may occur (red eyes, itchy, watery eyes). Allergies to trees can also cause itching in the larynx. Allergy to pollen is usually accompanied by severe fatigue.Trees responsible for allergic reactions
Most allergies are caused by six tree families (Betulaceae, Cupressaceae, Fagaceae, Oleaceae, Pinaceae and platanacées). Most of them are kittens trees: oak, ash, birch, hornbeam, alder, hazel ... But there are also trees without catkins, present mainly in the south of France. It is the cypress, plane trees, olive trees ... More unique, there are cases of allergy to exotic trees (cashew, coconut, papaya, palm trees ...).The tree pollen season
Allergies to tree are triggered earlier this year, or spring for the cash later. The pollens of cypress, alder and hazel are the first to appear (January). Birch and ash begin their pollination period in February. In March, it was the turn of the charm, oak and sycamore. Finally, the olive is the latest, with a pollen season that starts in May. However, by region, the timing of pollination may vary. For allergy sufferers, the National Network monitoring Aerobiological provides an early warning system to be notified at the onset of pollen in his department.Healing the tree pollen allergy
Like all pollinosis, allergy to trees must be treated to avoid serious complications. The respiratory disease can indeed evolve in allergic asthma. It must first avoid exposure to pollens. For this, we must know that the tree pollens are particularly present in the air on hot days, dry and sunny. Should then relieve manifestations of allergy by symptomatic treatment (antihistamines, steroids ...). Finally, we must treat the cause of the allergy desensitization therapy. This therapy, set up by an allergist, can learn the body to support the pollen allergen. Desensitization is a long (3 years), but it's the only way to get rid of allergy to trees.
