I think I may have worked out why I've been suffering with a runny nose and congestion/sneezing recently, particularly at night - the aircon!

Has anyone else experienced this, and is it simply a question of buying a humidifier? It seems odd to have one machine extracting moisture and another to add it...

Dehumidifying is is an unfortunate side affect of cooling air so yes if the air gets too dry you might need to humidify.

AC in large office buildings have built in humidifiers in the main air handling plant to prevent dry air.

Do you have something that can measure the humidity in your room.

I have a 'toy' thermometer/humidity meter which currently says 23C and 60%, though I doubt it's very accurate.

Ironically I have a DEhumidifier running in the garage to stop tools going rusty! So maybe I need a long hose to ship the humidity into the house nuts

Put a bowl of water next to your bed . We have a built in humidifier but it's mainly used during the winter alongside the warm air heating system , Canada based btw so normal .

That sounds remarkably easy... how big are we talking - cereal bowl or washing-up bowl?

Not sure it would keep up though, judging by how much condensate drips out of the pipe.

Aha, what we need is a system that feeds the condensate back into the room - and fills the bowl!

My wife suffers the same when we go away (ac not really a problem here in Northern Scotland) and a friend suggested the bowl of water trick.

I was (and still am) pretty sceptical, the amount of evaporation is tiny and there was no change at all measured by the humidity gauge when we tried it but my wife claimed to feel better - placebo I suspect but maybe worth a try.

When I used to work in an air conditioned office all day I used to suffer all summer with hay fever, since working from home after 2020 my symptoms, such as blocked nose have been significantly milder.

It's a standard travelling "hack" to hang a damp towel in a hotel room to counter dehumidification effect of the a/c.

Perhaps the symptoms of hayfever are exacerbated by low humidity?

Car aircon doesn't seem to do it - perhaps because it draws fresh air in from outside whilst split aircon is 100% recycled. There really should be a feature to introduce the condensate back into the blown air.

Around here, dehumidifying is a very desirable side effect of cooling air!

First step would be to get some hygrometers and see if the humidity is unreasonable in either direction.
Our outdoor humidity has been quite high quite often lately, so despite your aircon, it may be higher than you think indoors.

Pollen, other dust and mild infections are also possible.

22.7C and 62% in here currently. Feels about right.

The a/c unit will have an air filter somewhere, with dire warnings on how often to clean/change it. Perhaps worth looking at?
