The too cold spring has an advantage for people with hay fever:people with an allergy to grass pollen have fewer complaints.
There are 94 percent less grass pollen than usual. Unfortunately, there will be no cancellation. The grass pollen season is expected to start in early June.
On the Allergy Radar website you can indicate daily and check how much hay fever you can expect that day. Allergy Radar also has a handy app.
