Why Do Mosquito Bites Itch More At Night

For some people, mosquito bites itch more at night than during the day, for several reasons. These reasons include:

• Fewer distractions

As people wind down from their days and try to go to sleep, they may be more aware of their skin itching, because fewer things are going on that distract them from their mosquito bites than during more active times of the day.

• Cortisol

One of the ways your body fights inflammation involves cortisol. Known as the stress hormone, cortisol triggers your response to dangerous situations, and it fights the inflammatory response that causes itchiness. Generally, cortisol levels are lower at night, reducing the inflammation response to mosquito bites. The combination of fewer distractions and lower cortisol levels causes mosquito bites to itch more at night.

• Increased blood flow

Other things that can contribute to mosquito bites itching more at night center on the fact that when humans sleep, blood flow to the skin increases, releasing more heat to cool our bodies for a more peaceful sleep. This increased blood circulation to the skin can make mosquito bites itch more at night, as well.

• Hormone levels

Other hormones secreted by your body at night involve fluctuating levels of anti-inflammatory corticosteroids. Repairing tissue damage by day, corticosteroid and other hormone levels may be lower at night, causing mosquito bites to itch more at night.
