We care deeply about healthy sleep, and simply put, Americans are not optimizing the quality and duration of their sleep. Over time, suboptimal sleep can lead to cardiovascular problems, immune dysfunction, and even cancer.

In a 2021 longitudinal study published in the journal sleepelderly people with poor sleep quality were almost 60% more likely to get cancer1 than those with good sleep, regardless of whether they had a family history of cancer. (This is another reason to prioritize quality sleep!)
