WHY IS ECZEMA MORE ITCHY AT NIGHT?
Eczema becomes itchy because your skin is dry and inflamed, and inflammation is driven by a variety of chemical mediators, including a neuropeptide called substance-P. Additionally, inflammation increases blood flow, which also contributes to generating itch. This gets worse at night as our body’s levels of cortisol peak in the middle of the night. The cortisol hormone helps control inflammation and itch, so that’s why you feel naturally less itchy first thing in the morning.
