Quick response to — why is psoriasis so itchy at night?

Psoriasis is so itchy at night because the skin naturally cools down as the body sleeps, which causes the nerve endings in the affected area to become more sensitive and triggered.

For those who require further information

Psoriasis is a chronic autoimmune condition that affects around 2-3% of the world’s population. It is characterized by the rapid overproduction of skin cells, which leads to thick, red, and scaly patches on the skin. These patches are often incredibly itchy, especially at night, when the affected person is trying to sleep.

One reason why psoriasis is so itchy at night is that the skin naturally cools down during sleep. As the body temperature drops, the blood vessels in the skin constrict, which can cause nerve endings in the affected area to become more sensitive and triggered, leading to itching. This triggers the scratch-itch cycle, where scratching provides temporary relief but ultimately worsens the itch.

In addition, stress tends to aggravate psoriasis symptoms, and stress levels often decrease while we rest. This relaxation paradox can lead to a flare-up of symptoms at night. Moreover, people with psoriasis tend to have lower levels of melatonin, the hormone that regulates sleep, which means they may be more susceptible to sleep disturbances that exacerbate itching.

Interestingly, there is some evidence to suggest that people with psoriasis may be more prone to sleep disorders such as sleep apnea, restless leg syndrome, and insomnia, all of which can increase nighttime itchiness. However, more research is needed to establish a definitive link.

In conclusion, psoriasis is an uncomfortable and often debilitating condition that affects millions of people worldwide. The itchiness associated with psoriasis is particularly acute at night, due to a combination of factors related to body temperature, stress, and sleep disturbances. It is important for people with psoriasis to seek medical advice and treatment, as well as adopting various coping strategies to manage their symptoms and improve their quality of life.

As famous dermatologist Sandra Lee (aka Dr. Pimple Popper) puts it, “Psoriasis is so much more than just a skin condition. It can impact every aspect of a person’s life and cause a great deal of physical and emotional distress.”

Your skin experiences moisture and water loss at night as the body loses fluids and electrolytes. This causes dry skin, which leads to itching and irritation. The compromised skin barrier also adds to skin’s discomfort because water is not retained for adequate time periods in the skin cells.

Psoriasis is an inflammatory skin condition that causes itching. The root cause of itch in psoriasis is inflammation, which is mainly caused by cytokines such as IL-23. At night, the body releases more cytokines, which can increase inflammation and cause more itching. The mechanism of circadian rhythms in the body for the production of some chemicals called mediators involved in triggering and activating itch nerve fibers may also be linked to why many skin problems, including psoriasis, itch more at night.

IL-23 is a cytokine (protein) that sends signals between cells, mainly signaling a pathway leading to inflammation. Inflammation is a root cause of itch in psoriasis. At night, the body releases more cytokines, which can increase inflammation, thereby causing more itching.
