Q Strangely, I'm fine during the day, but the moment I get under the blanket at night my whole body starts itching. Why is it only worse at night?
A At night, body temperature rises slightly and blood vessels widen, making nerves more sensitive to itch signals than during the day. Being distracted by activity during the day also plays a role — once things go quiet at night, you notice the itch fully. Warm bedding and dry indoor air are also common contributors.
Detailed Answer
Nighttime itching results from a combination of rising body temperature, blood vessel dilation, and shifts in cortisol rhythm. Dryness from heating and bedding adds on top of that, making the itch feel more pronounced.
Korean Medicine Clinic Perspective
In Korean medicine, nighttime is seen as the time the body should be replenishing fluids and blood. When that recovery is incomplete, heat that was suppressed during the day rises toward the skin at night, intensifying the itch. For people with recurring nighttime itching, we often check sleep quality and internal fluid balance together.
