Why am I always cold?
Not a diagnosis: a head start. These are the three drivers most worth checking first, based on what the evidence says gets missed most often.
Thyroid first
Cold intolerance is one of its most specific signals.
Iron and circulation
Low iron means less oxygen delivery; hands and feet pay first.
Raynaud’s pattern
Fingers turning white then blue then red is its own named, manageable thing.
TSH, ferritin, full blood count
1. Start a two-minute note so the pattern becomes visible.
2. Take the test list above with you so you can explain the pattern clearly.
3. Read the evidence: Always Cold Hands and Feet? Your Body Is Trying to Tell You Something.
