Summer Checklist MCAS POTS CFS

This is the Top Things to Manage Summer Checklist

1. Temperature Control = Your #1 Protector

2. Hydration + Electrolytes (daily, not just on flare days)

3. Gentle Low-Histamine Pattern (not extreme restriction)

4. Consistent Antihistamine Support (doctor-prescribed)

5. Nervous System Pacing & Avoiding “Heat PEM”

6. Stabilise Heart Rate & Blood Flow

7. Avoid Big Triggers (your body is less forgiving in summer)

8. Calm Mast Cells by Calming the System

9. Prepare for outings (mini summer survival kit)

10. Track Patterns to Catch Flares Early

This is a five-page PDF summarising the key actions I will take to protect myself this summer. It goes with this article on my Substack When Your Body Overreacts: My Experience With Mast Cell Activation, found here.

This document was created using a conversation I had with AI about my symptoms, experiences and the crossover between my conditions.

It is my learning, shared in case it helps you.

Don't hesitate to get in touch with your medical professional if you suspect you have MCAS, if you're considering trying an antihistamine or any other treatment options. Always do your own research :)
