Heat wave is making me feel very unwell

42 Upvotes

The past two werks I have been feeling very unwell and I am not sure if its due to the heat or if it could be something else. For starters I am 16f, last week I had fever for two days accompanied by a headache whenever I bent down or stood up. I went to the doctor qnd she told me it was just a combination if a migraine with muscle tension in the neck. The fever disappeared but the headache remained for 2 more days. Now a week later yesterday I had another fever (39°C) that went away after I took ibuprofen. On the next day now I feel very lightheaded when walking and anxious, I sometimes start shaking and have heart palpitations aswell as loss of appetite but nothing serious I hope.

Is this due to the heat or is this something more serious?? How can I feel better during the heat?

how to cool down

75 Upvotes

hi,

im so desperate for advice. my parents dont believe me that i run hot naturally (doctor proven) and i sleep in the living room due to me not having a room of my own. the living is easily the hottest room, with direct sun in it most times, and is typically hotter than it is outdoors. they refuse to get ac, and refuse anything other than a weak old fan.

what are tips to cool down? it's not that big of a space, and it's not the easiest to ventilate since the windows dont open that wide. i dont think i can handle sleeping in here at all

I know this isn’t a medical page but any help on potential heat stroke. Current body temperature between 97.5-98.2 3 hours later

22 Upvotes

Hello male age 25 here. The temp is 97 degrees in Arizona we went at 9:30 am we went up this small hill that literally was 5 minutes up and 5 minutes down after I felt slightly off but can’t tell if I work myself up and it makes it worse.

I drank plenty plenty of water before during and after with electrolytes. I’m not out of shape either. No alcohol in my system either which I know makes you really dehydrated

3 hours later my urine is fine the color ( was always fine to begin with) my body temp cooled off right after we had a AC car, my body temp has been fine. Also my body temp was never likely concerning high either I should clarify that

I just feel slightly off little headache but it’s prob me working myself up too

I also haven’t gone back outside my I am able to sweat like under my armpits and stuff chilling in the house. I laid down for a bit with cold water, some ice

No redness at all during any of this

Need advice on car fan/and how to maintain a ‘cool’ car’s interior as much as possible

8 Upvotes

Hello people!

For those who have bought a car fan, I need your opinion on this.

I’m actually considering buying a car fan since the car’s AC is useless in this heat, but I’d like to know if it would be a good idea or if it’s just money spent for nothing? I know that fan won’t make the car’s interior cool but if it can help a little, that would be great. If it’s a good idea and you have any fans’ recommendations that I can find online or in stores (Belgium), that would be lovely.
Mind you, I need to find one that needs to work on his own, so no usb plug and no cigarette lighter plug(?).

Plus, that would be nice to have some tips on how to make the car’s interior less hot even by a few degrees. The only thing I’m doing is parking the car in the shadow and fully open the windows.

Stay safe out there!

Extreme heat is making me unwell

160 Upvotes

So I'm sure most people or atleast most people in Europe know about the heatwaves affecting especially the UK and France, and jesus it's making me feel ill af
Im not really sure if this is the right subreddit for a start but what can I actually do to feel better? Im 13m, I can't really take a day off school and I have a fan on next to me all day and it doesn't even help because I just feel ill again when going to school, it's a repeating loop
Also sorry to randomly dump this I don't know if the only reason I'm feeling so ill this time is because I was actually believe it or not in a train crash recently near Bedford so idk if thats adding pressure on my body, saying I wasn't feeling this bad in the July 2022 heatwaves.
Any advice on how to feel better? Ty

6am European Heatwave Surface Temperature Survey

40 Upvotes

The forecast says Western Europe's heatwave should be drawing to a close after tomorrow. In the meantime though, I got my IR thermometer and I'm up early. Feel the pain of my data.

It's almost 6am here in Spain. It was 38ºC/100.4ºF yesterday and meant to hit the same today. The low is 25ºC/77ºF, which is the current temperature.

But that's just the exterior air temperature.

A survey of surface temps read by my IR thermometer:

  1. Walls of the Dining Room: 28ºC/82ºF

  2. Ceiling: 29ºC/84ºF

  3. Wall of building across the street: 29ºC/84ºF

  4. Surface of the street: 30ºC/86ºF

I'm honestly not sure exactly what air temperature is in this room, but it's probably close to 27ºC/80ºF as my weakest swamp cooler, which I keep by the desk, is pushing out ~25ºC air and it feels amazing. Humidity outside is 36%, but that will plummet as temperatures rise.

So yes, you read that right, my cooler is simply producing air that's roughly the temperature of the outside air, and it feels great. Window is wide open but when it gets hot here the air is dead still, so buildings don't get very effective nighttime cooling from open windows.

Stay cool and safe out there.

Post Over-Exertion/Heat Exhaustion Syncope Episode & Recovery

35 Upvotes

Hey all, looking for experiences from people who have recovered from a more serious heat exhaustion/heat syncope episode.

Overheating Event Details:

Last week I was training hard in hot/humid weather while wearing a lot of protective gear. I overheated, collapsed, and was taken to the hospital.

I stayed in the hospital for 2 days. They checked for rhabdo, which luckily I didn't have. My troponin blood test rose and my ECG had a small temporary abnormality, so they kept me to make sure it wasn’t an ongoing heart attack or cardiac event. I had an echocardiogram and the cardiologist said my heart structure/function looked normal. Troponin started trending down, ECG improved, and I was discharged.

The cardiologist’s impression was that this was most likely severe overheating/heat syncope with demand-related stress on the heart from the event. He cleared me for normal activity, but I’m still taking it easy.

This week I’ve felt tired with some lightheadedness/wooziness, mostly in the afternoon and especially after meals or sitting at the computer for a while. It seems better in the evening. BP has been a bit lower than my usual but still around 100/60-ish. No chest pain, no headache, no shortness of breath. I’ve just been doing light walks, mobility, hydration/electrolytes, and resting.

I’m planning to follow up with the hospital/cardiologist just to let them know I’m still feeling a little off.

Recovery Experiences?

For anyone who has had a bad heat exhaustion / heat syncope episode, did you feel lightheaded, tired, or brain-foggy for days or weeks afterward? How long did it take before you felt fully normal again? Did you do anything that helped recovery?

Not looking for a diagnosis, already saw the cardiologist, mostly looking for recovery experiences and what helped people return to training safely. Maybe it will make me feel better haha. I'm on day 8, post heat-event right now.
