Scratching an itch causes minor pain, which prompts the brain to release serotonin. But serotonin also reacts with receptors on neurons that carry itch signals to the brain, making itching worse.
Does serotonin affect skin?
The serotonin receptor, HTR7, caught the scientists’ attention because the itchiest mice expressed the most HTR7 in the neurons that innervate the skin, and because abnormal serotonin signaling has long been linked to a variety of human chronic itch disorders, including eczema.
Does scratching an itch release serotonin?
Scratching an itch is the most satisfying instant relief available, but according to a new study from Washington University School of Medicine in St. Louis, it’s actually just a mental scam: scratching causes the brain to release serotonin, which intensifies the itch sensation.

Does coffee deplete serotonin?
It was previously reported that caffeine has the capability to reduce brain serotonin synthesis by inhibiting tryptophan hydroxylase, the rate-limiting enzyme for central serotonin biosynthesis (Lim et al., 2001), and/or to reduce brain serotonin/dopamine ratio by blocking adenosine α1 and α2 receptors within the CNS.
