6 Reasons Insect Bites Itch More At Night

Itchy insect bites at night can cause frustration and lead to restless sleep. The science behind the body's physiological processes contributes to nighttime itchiness. Here are the factors that cause it:

Increase in Body Temperature

We are more active during the day, and our body temperature increases. This can help to reduce the intensity of itchiness from insect bites. However, our body temperature may rise slightly when resting at night. This may increase the power of itchiness caused by insect bites.

Reduction of Environmental Distractions

At night, there are fewer distractions in our environment. This can make us more aware of sensations on our skin, including the itchiness from insect bites. During the day, we may be distracted by work, friends, and other activities that can help to reduce our perception of itchiness.

Release of Histamines

When an insect bites us, our body releases histamines in response to the foreign substance injected into our skin. Histamines help our body fight off foreign substances and cause the skin to become red, swollen, and itchy. At night, our body may release more histamines in response to the bites, making them feel more intense.

Hormone Levels

Besides cortisol, other hormones such as testosterone and progesterone can also affect our perception of itchiness from insect bites. At certain times of the month, such as during menstruation, hormone levels can fluctuate, making us more sensitive to sensations of itchiness.
