Wake, sleep, repeat. Day in, day out. It’s a pattern we’re so familiar with that most of us give it little, if any, thought. The sleep-wake cycle is simply one of life’s daily rhythms. In fact, it’s one of our circadian rhythms. Put simply, circadian rhythms are physical, mental and behavioral changes that our bodies experience over a 24-hour cycle. They affect our sleep, our body temperature, our appetite, our hormones and more. And it turns out these daily rhythms may play a key role in cancer treatment.
