Itchy Skin Bed

Do you suffer from nighttime itchy skin? Known as nocturnal pruritus, the condition can easily disrupt your sleep cycle, leaving you feeling exhausted. The causes of nighttime itchy skin vary from minor to severe. 

9. The Body’s Circadian Rhythms

Circadian Rhythm

Everyone has a natural circadian rhythm, also referred to as your cycle. The process regulates your skin’s functions, temperature, barrier protection, and even the fluid balance within your cells. 

All of the natural skin changes take place at night. In fact, when the sun sets the blood flow to your skin increases to help warm you. The warming can cause your skin to feel itchy. 

During the night, your body also releases more cytokines, which can lead to inflammation. Also, you produce increased corticosteroids, which help to reduce the inflammation. The battle within your skin’s cells can lead to nighttime skin itchiness. 

Your skin loses water at night. This is especially true during the dry winter months. Patches of parched skin start to itch. 

According to Michele Green, M.D., a New York-based dermatologist, “These conditions can trigger a hormonal imbalance, autoimmune response, or sensory response that results in itchy skin at night.” 

8. Distractions and the Night

Sleep Distractions

Your skin might always be itchy, but you notice it more at night. During the day you are distracted with work and other activities, so you don’t notice the annoying sensation like you do if you are lying in bed with nothing else on your mind. The itch will feel more intense due to fewer distractions.
