Irregular sleep habits 'can affect cancer risk in men'

7 November 2016

A new study has demonstrated the elevated risk of cancer faced by men with irregular or unusual sleeping habits.

Conducted by the Huazhong University of Science and Technology, the study reviewed data from around 27,000 retired auto manufacturing workers to investigate the effects of night shift work, daytime napping and excessive night-time sleep on cancer trends.

Those who had worked night shifts for more than 20 years had a 27 per cent higher risk of cancer incidence, with those who did not nap during the daytime experiencing double the risk of cancer compared to those who took naps of up to 30 minutes.

Men who slept for more than ten hours each night also had an increased risk of cancer, a trend that was not observed in women.

The researchers also found that men with at least two of the aforementioned sleep habits had a 43 per cent increased risk of cancer incidence, as well as a twofold increase in cancer mortality, compared to those who exhibited none of these habits.

This underlines the need to stick to a conventional sleep cycle for optimum health outcomes.
