Sleep health – including sleep duration, efficiency, and quality, as well as sleep timing and regularity – is important to overall health. Poor sleep may directly affect mortality risk and influence risk for cancer and other non-communicable diseases through its impact on immune function, stress response and inflammation, DNA repair, and metabolic and hormonal activity. It may also impact mortality through its effect on modifiable risk factors, including physical activity, diet, alcohol, and tobacco use.

Existing evidence indicates that sleep duration is associated with cancer mortality. However, across sites, risk may vary by sleep duration – both short (<7 hours/night) and long (>9 hours/night) sleep duration. Findings are also mixed regarding the association between sleep duration and cancer risk. Other aspects of poor sleep health, including poor sleep quality and irregular sleep timing due to shift work, have also been linked to increased risk of cancer, highlighting the need for future research in these areas.

Additionally, poor sleep health is associated with poorer treatment efficacy, adverse physical and mental health outcomes, and increased mortality in cancer survivors. The mechanisms connecting sleep health and cancer survivorship are not fully understood and are an evolving area of study.

The recommendations stratified by age are 7 or more hours/night for adults 18-60 years, 7-9 hours for adults 31-64 years, and 7–8 hours for adults 65 years and older.

Percentage of adults aged 18 years and older who report getting sufficient sleep, defined as an average of 7 or more hours of sleep per day.
