The Link Between Sleep and Breast Cancer Disruptions of your circadian rhythm,
which can result from poor sleep, may
play a role in breast cancer. Occasional bad nights are nothing
to worry about, but chronic sleep
issues are a different story. Waking up more than twice a night was associated with a 21% increase in breast cancer risk in a study in the European Journal of Cancer Prevention. These tips will help you get
the nightly rest you need. Shut down disruptions. Use a pink noise machine, swap out your pillow, or try a different sleeping position. Stick to a two-hour window. Aim to wake up and fall asleep within the same two-hour window every day. Use mood lighting. Cut back on the amount of
brightness you’re exposed to
an hour or two before bedtime.
