Every time it has gotten extremely hot this summer I have had episodes of seizure like activity. I feel very off that day and then I end up
Having a seizure. When it cools off they seem to go away. Right now our central AC is out so it’s just a tiny window unit and a small fan in my room. We have had Heat Indexes >105° with humidity in the 80’s- 90’s and I’ve had 4 seizures in 5 days. When it was in the low 80’s I didn’t have any seizures. 🤷🏻‍♀️ Does anyone have this happen or am I just crazy?

You aren’t crazy It has happened to me when I fainted while being in the heat and I was told that I had a seizure, apparently this happens . During the heat if you are out and about I suggest to have a cool wet cloth around your neck it has helped me during hot summer nights cause of having no AC just a fan . It refreshes you and aids with our intolerance to heat. Sending hugs and blessings 🌹

Heat sensitivity in MS is a serious concern that can significantly impact symptoms. When core body temperature rises, even slightly, it can cause nerve signals to slow down or become blocked entirely due to the demyelination process. This interference with neural conduction can cause various neurological symptoms to worsen.

Heat sensitivity in MS is a serious concern that can significantly impact symptoms. When core body temperature rises, even slightly, it can cause nerve signals to slow down or become blocked entirely due to the demyelination process. This interference with neural conduction can cause various neurological symptoms to worsen.

Given the severity of your symptoms, it's crucial to seek immediate medical attention. Seizure-like activity should always be evaluated by a healthcare provider, especially when occurring with such frequency. In the meantime, here are some immediate steps to consider:
- Try to keep your environment below 70°F if possible
- Use cooling methods like cold compresses or cooling vests
- Stay hydrated
- Avoid direct sunlight
- Consider temporary relocation to a cooler environment until your AC is fixed

The connection between heat and MS symptoms is well-documented, and you're not "crazy" for noticing this pattern. Many MyMSTeam members report severe reactions to heat, with some even requiring hospitalization during extreme weather.

Even if no one else experiences it, it sounds like you ARE experiencing it. And are in a situation where it could happen more.

If you can’t afford cooling products, get some towels and wet them. Store them in the freezer. Get a dish pan or foot bath situation. Fill with cold water and ice. Put feet in cold. Place cold towel on neck. That creates like a cooling circuit for your body.

Even just the cooling towel around the neck/shoulders should help significantly.

Full on seizure? Or just muscle spasms? The heat can cause pseudo flares. Get you a free ice vest it can be very trying https://mymsaa.org/msaa-help/cooling-products/
