Women are even more so. Research has found that an increased risk of cancer may be related to short sleep time. Risk | time | sleep
On August 14th, a reporter from Science and Technology Daily learned from Tongji Hospital affiliated with Tongji Medical College of Huazhong University of Science and Technology that Professor Zhang Wanguang's team in the Department of Hepatology at the hospital found through data analysis of the China Health and Elderly Care Tracking Survey that short sleep time is associated with an increased risk of cancer; Women are more likely to develop cancer under the habit of long-term sleep deprivation. The relevant research results are published in the academic journal Cancer.
Zhang Wanguang introduced that the study included more than 14000 participants, who were followed up every two years to track changes in their sleep time and cancer incidence.
During an average follow-up period of 7 years, the team found that short sleep duration was associated with an increased risk of cancer among participants, with significant differences in risk among populations of different genders and weights; There is no significant correlation between long sleep duration and cancer risk.
Compared with participants who slept 6-8 hours at night, participants who slept less than 6 hours had a 41% higher risk of cancer. Compared to participants who took a nap for more than 60 minutes, participants who never took a nap had a 60% increased risk of cancer. Compared with participants who slept for 6-8 hours at night and took a nap for more than 60 minutes, participants who slept less than 6 hours at night and never took a nap had an 82% higher risk of cancer.
Compared to participants with a total sleep time of 7-8 hours, participants with a total sleep time of less than 7 hours had a 69% increased risk of cancer. And this risk is more significant among male, overweight, or obese participants, with increases of 95% and 70%, respectively.
The above study also found that changes in sleep duration during follow-up were related to the risk of cancer in female participants, but not significantly associated with male participants.
Under the habit of sleeping less than 6 hours at night for a long time, the risk of cancer in the female population increases by 41%; Meanwhile, women who have a total long-term sleep time of less than 6 hours have a 126% increased risk of cancer compared to those who maintain 7-8 hours of sleep.
Researchers suggest that ensuring adequate sleep time is crucial, especially for women who should pay more attention to sleep.
