Common Sleep Issues Associated with Cancer

Getting a restful night’s sleep is a challenge for many cancer patients. Pain from the cancer itself, fatigue and discomfort from chemotherapy, and medication side effects are just a few of the things that make sleep elusive for cancer patients. Worse, not getting enough sleep weakens the immune system and can exacerbate symptoms or negative side effects.

An increasing amount of research has found links between poor sleep and several cancers. Keep reading to learn what the latest research suggests about the connection between cancer and sleep, and how you can get better sleep if you’re undergoing cancer treatment.

Does lack of sleep cause cancer?

Regularly getting a good night’s sleep is an essential part of your overall health. While sleep itself has not been deemed a causal factor for cancers, researchers have associated certain sleep disorders with an increased risk of cancer. The three main sleep issues correlated with cancer are chronic sleep deprivation, sleep apnea, and shift work sleep disorder.
