Why is eczema worse at night?
Eczema, also known as atopic dermatitis, is a chronic skin condition that affects millions of people worldwide. One of the most common questions among eczema patients is why their symptoms tend to worsen at night. Understanding the reasons behind this can help individuals manage their condition more effectively and improve their quality of life.
One reason why eczema can be more pronounced at night is due to changes in body temperature. As the body cools down during the night, blood vessels in the skin constrict, which can reduce blood flow and make the skin more sensitive. This sensitivity can lead to increased itching and inflammation, exacerbating eczema symptoms. Additionally, the cooler temperatures can also cause the skin to become drier, further irritating the affected areas.
Another factor that may contribute to night-time eczema flares is the body’s natural circadian rhythm. The circadian rhythm is an internal biological clock that regulates various bodily functions, including sleep and wakefulness. During the night, the body produces more histamine, a substance that can trigger itching and inflammation. This increase in histamine production can lead to more severe eczema symptoms during the night.
Moreover, the reduced level of light at night can also play a role in the worsening of eczema symptoms. Exposure to light, especially natural sunlight, can help regulate the immune system and reduce inflammation. When it’s dark, the immune system may become more active, leading to increased inflammation and itching. This is particularly true for individuals with a weakened immune system, such as those with eczema.
Lastly, stress and anxiety can also contribute to the worsening of eczema symptoms at night. Many people find that their stress levels are higher during the night, which can exacerbate their eczema. This is because stress can trigger the release of inflammatory chemicals in the body, leading to increased itching and inflammation.
In conclusion, there are several reasons why eczema can be worse at night. Understanding these factors can help individuals develop strategies to manage their symptoms more effectively. By addressing issues such as temperature changes, circadian rhythm disruptions, reduced light exposure, and stress, eczema patients can improve their comfort and sleep quality during the night.
