what does a hot flash feel like

A hot flash feels like a sudden, intense sensation of warmth that typically starts in the chest and quickly spreads to the neck, face, and upper body. The skin in these areas may become flushed, red, or blotchy, and you might experience heavy sweating mostly on the upper body. Along with the heat and sweating, a fast or irregular heartbeat, dizziness, shaking, and a feeling of blood rushing through the body can occur. After the hot flash subsides, you might feel chilled or start to shiver due to the rapid loss of body heat. The episode usually lasts from 1 to 5 minutes but can vary in duration and intensity from person to person. Hot flashes can happen any time of day or night, with nighttime occurrences called night sweats, which may disrupt sleep. They often cause discomfort and anxiety, especially if they happen frequently or severely enough to interfere with daily activities
