Poor sleep schedule linked to breast cancer
According to CBS News, women's sleep schedules might have an effect on whether they develop breast cancer. One in every 100 women who are early risers gets breast cancer, whereas two in every 100 women who wake up close to noon develop breast cancer.
A source from CBS News says, "Cancer risks associated with a person's body clock and sleep patterns have been reported in previous research and the UK researchers wanted to explore sleep traits in more detail, as well as any genetic factors underlying this."
A researcher from Cancer Research UK Integrative Cancer Epidemiology Program, Dr. Rebecca Richmond, analysed genetic variants related to whether or not someone is an early or late riser between 220,000 women. According to Dr. Richmond, "people whose genes made them more likely to be early risers were less likely to develop breast cancer by as much as 48%." This was shown from the study of the 220,000 participants.
Another analysis conducted by the doctor showed that between 180,000 participants who wake up early, 40% have lower risk of breast cancer. Also, women who don't meet the suggested seven to eight hours of sleep each night increase their risk of breast cancer by 20%.
According to Richmond, "Sleep is likely to be an important risk factor for breast cancer, but isn't as large as other well-established risk factors like BMI or alcohol."
According to webmd.com, other risks related to a bad sleep schedule are the following: heart disease, heart attack, heart failure, irregular heartbeat, high blood pressure, stroke, and diabetes. A source from WebMD says, "According to some estimates, 90% of people with insomnia, a sleep disorder characterized by trouble falling and staying asleep, also have another health condition."
