During a hot flash, you may experience:
- A sudden feeling of warmth spreading through your upper body and face
- A flushed appearance with red, blotchy skin
- Rapid heartbeat
- Perspiration, mostly on your upper body
- Feeling chilled as the hot flash subsides
Hot flashes vary in frequency — you may have few or many in a day — and each hot flash usually subsides in a few minutes. They’re particularly common at night. Most women who experience hot flashes have them for more than a year, but they usually stop on their own within four to five years.
