Alder pollen

Alder (Alnus glutinosa, Alnus incana) on siin õhus alates february to april, tipp late March to mid-April. Allergeenne potents: high. Ristreageeribapple, pear, cherry, plumja teistega.

See on viiteteave, mitte diagnoos ega ravikava. Õietolmukalender ei ütle, millele te allergiline olete, ja ükski leht ei saa toitu teie jaoks ohutuks tunnistada — ainult sildi pakendil teie käes ja arst, kes teie ajalugu tunneb. Kõik, mis ületab kergeid, lühiajalisi sümptomeid suus või ninas — turse, mis mõjutab hingamist või neelamist, nõgestõbi suust eemal, vilistav hingamine, oksendamine või minestustunne — on hädaolukorra küsimus, mitte lugemise küsimus.

Kus see siin kasvab

Two alders matter here. Black alder holds the wet ground — river banks, ditches, fen woodland — and grey alder colonises abandoned farmland, which is why it has spread so widely across Estonia, Latvia and Finland over the last century. Both are wind-pollinated and both flower on bare wood, so a stand of alder along a stream is a pollen source in plain sight.

Millal see on õhus

Alder overlaps hazel and hands over to birch. In the Baltic and southern Finland the window is February to April with the strongest days between late March and mid-April; further south, in Denmark and southern Sweden, it starts weeks earlier. Grey alder tends to flower slightly ahead of black alder, which stretches the season at both ends in regions where both grow.

Kuidas see tundub

Alder produces classic upper-airway hay fever: blocked and running nose, itchy palate, red gritty eyes. Because it arrives in early spring, it is common for people to attribute a whole month of symptoms to a persistent virus and only recognise the pattern when it repeats the following year at the same time.

Millega see ristreageerib

Alder is a Fagales tree and Aln g 1 is a Bet v 1 homologue, so alder allergy travels with hazel, birch and oak almost as a single sensitivity. Most people are found to be sensitised to the group rather than to one member of it, and the birch food list applies. Clinically it is usually the birch season that gets the credit, because it is louder — but for someone whose symptoms begin in March, alder is the trigger and birch is still weeks away.

Ristreageerimine ei ole sama mis toiduallergia, mis algas toidust, ja erinevus otsustab, kui tõsine see on. Lugege kuidas oraalse allergia sündroom töötab enne järelduste tegemist sellest nimekirjast, ja pange tähele, et mitmed neist toitudest ilmuvad ka neljateistkümnel deklareeritaval ELi allergeenil täiesti eraldi põhjustel.

Mis tegelikult aitab

Alder is one of the five pollen types the CAMS European forecast — the data behind the Open-Meteo pollen feed — actually models, so a forecast number exists for it. Use it the way a rain forecast is used: to decide whether to open a bedroom window overnight or hang washing outdoors, not to decide whether you have an allergy.

Mis loetakse valesti

A common assumption is that alder in a garden is the problem and cutting it solves it. Wind-pollinated tree pollen travels tens of kilometres and is measured hundreds of kilometres from source; removing one tree changes very little. What does change things is keeping it out of the bedroom — closed windows on windy dry afternoons, and hair washed before the pillow.
