Humidity, more than just a hair problem?

[Katiepops]

I fainted after a run. Not today, some time ago. About 2 months ago on a muggy evening in the hills I had to stop through dizziness. After Parkrun today, I had to sit down because I felt dizzy. The only thing that seems to be the same was the weather. Really high humidity. Instant recovery and no heart issues (had an ecg and a check up by the doc) but really lightheaded while running. On each run breathing was my main problem. Couldn’t get my breath almost like I had asthma, which I don’t.

Does any one else have this? Any medical types out there - is this a thing?

Hi! I get very dizzy too and posted about it a couple of months ago. Oldfloss suggested readin this: runnersworld.com/health-inj...

I now keep walking and moving around quite a bit after running and it does help

It’s true, and I know that I should keep moving and really feel better if I do. But I run lots during the week and this only seems to happen in slightly odd weather conditions; humidity or high pressure! 🙃

Yes or when I push myself more. After Tring pR I’ve also had to sit / lie at the end because felt like fainting. Maybe it’s the added difficulty

Hi, l am getting checked out for exercise induced asthma. I get a tight chest and can't catch my breath, no dizziness though. Some runs are worse than others. I have a blue inhaler which definitely helps and am booked in for a long function test.

Maybe monitor it and get checked out of no improvement.

Poor you Katie, that’s not nice. Humidity must surely be a factor? Stating the obvious, maybe you’re not adequately hydrated. I’ve had dizzy/fainting spells in the past (pre-running days) and I can relate all of them to heat and lack of hydration. 🥵

I pop an electrolyte tablet in my water on run days now, and have some before and after. Even in this humidity, I’ve felt fine - just a bit slower (is that even possible?!) than usual, but I don’t push it. 🏃‍♀️

Maybe a trip to the doc for peace of mind is on the cards for you though? Take care. ❤️

Hi katiepops, I used to get this as I started extending my runs to 10 . I was on hypertension tablets at the time to reduce blood pressure. The running had been reducing my blood pressure too. (The great thing is the doc took me off the tablets.). I still get a bit dizzy after pushing really hard at parkrun finish so I keep walking around for a while and drink water straight away. I found the runnersworld article reassuring.

I remember Stephen_UK felt dizzy during one of his parkruns, it was the very hot Saturday a few weeks ago.

I do have seasonal asthma and often have difficulty catching my breath, it helps to really exhale (I cough, but another poster suggested breathing out like trying to mist up a mirror). It does help replace stale air in your lungs and make it easier to breathe.

I have a Ventoline inhaler, which helps, but if I run outside when the pollen is bad I do feel dizzy and sick.

The other possibility is anaemia. I fainted after giving birth to my first with anaemia, after exertion. Is there any correlation with your periods or times when you have felt really tired before even running ?
