This year, I had my first summer without needing to take antihistamines in over a decade, I actually wonder what has caused this

Re: Doctors Might Have Been Focusing on the Wrong Asthma Triggers
#42I have had asthma my entire life, and it definitely flares up with airborne irritants. There has been awesome citizen science work going on helping people understand the direct link between anything that emits smoke and asthma attacks: https://www.healthaffairs.org/doi/10.1377/hlthaff.2017.1315 They even found that parents waiting to pick up kids at schools with their ICE engines running increased PM2.5 inside the en…
I've apparently never had asthma in my life, until I moved to Sydney, Australia for a while. It's a city which _loves_ cars. I used to cycle about 20 minutes to the office, the view was beautiful but the traffic was horrendous. I used to wheeze and struggle with breathing a lot more than usual. The doctor diagnosed me with "seasonal asthma" and gave me a ventolin prescription, which I've never felt the need to refill…

Isn't most PM 2.5 pollution produced by brake pad and tire wear, which is made worse by EVs due to their weight?
These are idle cars which are not braking, so the PM2.5 here is purely the engine pollution. City life might not be affected as much, but school buildings with cars waiting outside will be!

Idk, if you bothered to read the study that you are pointing to in your coup de grace, you'd would realize your cited sources admit that EV's create no more particulate pollution than ICE engines. Your cited study actually states that EVs do reduce particulate pollution but only by a couple percent, which is opposite of "creating more" for those who prefer evidence based positions. It's almost as if regenerative brea…
The original GP's post had two points: - most PM 2.5 pollution is produced by brake pad and tire wear - which [i.e. PM 2.5 pollution produced by brake pad and tire wear] is made worse by EVs due to their weight These are direct quotes from my links: - "A large fraction (50-85% and up to 90%) of traffic generated PM10 and PM2,5 is not due to the exhaust emissions by the motor, but rather to non-exhaust emissions (brak…
The study cited to me in order to defend the point that EVs make more particulate pollution flat out found that EV's create less particulate pollution.
> A positive relationship exists between vehicle weight and non-exhaust emissions."
As others already pointed out, that is the same study, the same study that found that EV's create less particulate pollution. The more weight = more particulate emission part did not control for EV regenerative breaking. So your position is ignorant at best and disingenuous at worse.
This will be my last comment here on the account that I will not debate facts with random people on the internet. If you can't be bothered to read the study, don't cite it, don't reference it and for god's sake don't try to use it to say something that is literally the opposite of it's findings.

If the ev has regenerative braking, the brakes actually last much longer than in ICE cars. Not sure how tires are affected but I'd imagine they do have a shorter life, and I'm not sure how the longer brake life balances with (probably) shorter tire life from a pollution perspective
Why would tires last longer in an ICE vehicle? I don't think tires care what makes them spin.

Electric cars are heavier due to the battery.

It depends on exactly which car you are comparing. The Tesla Model 3 is somewhere around 3500 lbs, isn't it? That's pretty average for a car these days.
And there are plenty of big SUVs that have a similar weight to the heavier EVs.
Besides, you can't assume that electric cars use the same tires as non-electric ones.
There is a huge range of tires out there from extremely long wearing ones to sticky ones that last a fraction of the time.

#48Surprised not to see exercise listed. It’s a common trigger for asthma attacks, especially in cold dry air, and I bet there were pretty big changes in exercise patterns for a lot people during the pandemic.

#49I certainly noticed this - over the last year I've gone from using reliever inhalers several times a week to not needing them for months. I did also start a new medication, Montelukast, around the time of the first lockdown, so it could conceivably be due to that in my case - but not having a chest infection at all for the last 18 months whereas I used to get one a year or so has been lovely.
PSA: Montelukast (Singlar) can slowly and subtlety "change your mind" [0] https://www.fda.gov/drugs/drug-safety-and-availability/fda-r...
Any idea what to use to replace it?
Friend of mine cannot forget to take it, or their chest/airways are quite heavy.
Does it take time for the body wean off?

Brake. The word is brake.
I am dyslexic, I swap words like that frequently, shit happens.
But if that is all you have to add to this discussion, I wonder why you bothered.
