Sleep deprivation can play a role in the body’s inflammatory process, potentially increasing inflammatory molecules like cytokines, interleukin-6, and C-reactive protein (an inflammation marker that’s often elevated in people at risk for heart disease and diabetes). Chronic inflammation can lead to the development of diabetes, stroke, heart disease, Alzheimer’s disease, and cancer. Studies have shown that acupuncture may help to improve insomnia symptoms, total sleep time, and sleep efficiency, as well as symptoms of conditions that can affect sleep, such as restless leg syndrome, sleep apnea, pain, anxiety, and depression. Improving sleep may help to decrease inflammation in the body.
