We’re very passionate about sleep health, and simply put, Americans aren’t optimizing the quality or duration of their sleep. Over time, suboptimal sleep can lead to cardiovascular health problems, immune dysfunction, and yes—even cancer. 

In a 2021 longitudinal study published in the journal Sleep, older adults with poor sleep quality were almost 60% more likely to develop cancer1 than those with good sleep quality, regardless of whether or not they had a family history of cancer. (Just another reason to prioritize quality sleep!)
