When most people think of hot flashes, they imagine sudden sweating and heat.
But during perimenopause, hormonal shifts can trigger many different sensations that don’t always feel “hot.”
These lesser-known hot flash variations confuse many women — and often go undiagnosed.
If you’ve felt sudden chills, anxiety rushes, burning skin, or heat without sweating, hormones may still be the cause.

Why Hot Flashes Feel So Different
Hot flashes are caused by instability in the brain’s temperature-regulation center, which is heavily influenced by estrogen.
As estrogen fluctuates:
- The brain misreads body temperature
- Blood vessels dilate or constrict suddenly
- Stress hormones amplify sensations

1. Cold Flashes (Yes, They’re Real)
Cold flashes feel like:
- Sudden chills
- Goosebumps

These happen when blood vessels constrict instead of dilating — often right after a hot flash or during estrogen drops.

2. Anxiety or Adrenaline Rush Flashes
Some flashes don’t feel hot at all.
Instead, you may feel:
- Sudden anxiety
- Racing heart
- Chest tightness
- Sense of urgency
These are often cortisol-driven flashes, where stress hormones surge alongside estrogen fluctuations.
