Reducing Risk of Cancer: How Sleep Improves Your Health

Reducing Cancer

and Health

Maintaining quality sleep is one of the most important health decisions you can make. Not getting enough sleep can increase your risk of many diseases, including cancer. While research is ongoing, it’s clear that the quality, quantity and timing of your sleep can all impact your risk for cancer. By getting adequate sleep, you’ll have greater control over your health and reduce your risk of developing cancer.

The Relationship between Sleep and Cancer Risk

Studies have found that sleep is linked to many forms of cancer, including colorectal, breast, and prostate cancer. While researchers are still trying to identify the exact connection between lack of sleep and cancer, there are several theories. It’s believed that not getting enough sleep can cause changes in hormone levels, including higher levels of the stress hormone cortisol and reduced levels of melatonin, which is the hormone that helps regulate the body’s sleep-wake cycle. Disruptions of hormones can lead to changes in how cells grow and divide, possibly increasing the risk of cancer.
