@mommas2cents: If you have low iron or low ferritin, you may notice that hot weather feels much harder to tolerate than it used to. Iron helps your body carry oxygen to your tissues and muscles. When iron levels are low, your body has to work harder to function normally. This can make you feel: * Overheated easily * Sweaty with minimal activity * Dizzy or lightheaded in the heat * Weak or exhausted faster than others * Short of breath when temperatures rise * More prone to headaches during hot weather Some people with iron deficiency find that even a warm room, a hot shower, or a short walk outside leaves them feeling drained. If the heat leaves you exhausted, dizzy, or feeling like your battery dies instantly, it may be worth checking your iron levels. #irondeficiency #lowiron #lowferritin #womenshealth #ironinfusion

I’ve been dealing with heat intolerance and extreme sweating when it’s barely hot out for years and the doctors never told me it could be from my low ferritin level😫

WAIT….. you’re telling me that my heat intolerance caused by my fibromyalgia and use of SSRIs is worsened by my very low ferritin?! And I’ve been complaining about this for YEARS and no one believed how serious it was for me?! Cool cool. I seriously can never delete TikTok.

why is nobody talking about this, i always thought that when you have low iron/ferritin you are supposed to be always cold. my ferritin was 15 and when i complained to the doctor about heat intolerance, they only talk about checking thyroid. i honestly doubt there is anything wrong with my thyroid, looking at other symptoms i should then have, but don't. seeing on tiktok how many people have it because of low iron, it makes total sense for me.

When I get hot just from making dinner, sometimes I can’t even eat right away because I become so nauseous and get diarrhea along with all the other things you posted. I will mention this at my appointment next month. Thanks for the post

I work in sheet metal fabrication and let me tell you! The heat and over exertion (I work with what some consider extremely heavy sheet metal and sheet metal parts) is absolutely exhausting- my supervisor, along with coworkers, for the last 3 years have witnessed me passing out throughout 12hr shifts… currently as of today my iron is at 31 (literally had labs drawn this morning), iron saturation is at 7, ferritin 4.1…

You mean I might not be allergic to heat?! It’s just my iron?!?!😳 This makes so much sense why when I was getting infusions over the summer I felt less affected!

I wonder how long my ferritin has been low, cause I’ve had this for years and they recently just tested it and now that I’m on iron I don’t get it as much anymore (it’s still pretty bad).

As a low iron & Ferritin girl on liquid iron currently…in the UK heatwave too - my heart beats so fast when I’m laying in the sun!! It’s all due to your blood has a reduced capacity to carry oxygen, so your heart must pump faster to deliver enough oxygen to your organs! But I also feel so dizzy & weak when I get up from sunbathing too!!!

My doctor would call this a sun allergy and give allergy pills instead of working on getting a better iron/ferritin level. 🤷♀️
