'Hayfever' season

[Penguin68]

This is the start of the 'hayfever' (actually at this time tree pollen) season - which means that those susceptible (as I am) will start having symptoms not unlike some elements of Covid-19 - particularly breathing difficulties if your histamine response triggers asthma. Obviously don't panic - but also remember that other symptoms will include sneezing and watery eyes - all of which will bring your hands to your face more frequently than for others (and make you an annoying disperser if by chance you do have Covid-19).

In Japan, where 50% of the population appears allergic to red cedar pollen - one of the iconic Japanese trees - many wear face masks to protect them from the pollen (quite large particles). Although simple face masks are not particularly encouraged as far as Covid-19 protection is concerned, they may help you if you are a tree pollen sufferer. And will help others if you are suffering both a pollen-triggered histamine response and Covid-19.
