'Less sleep makes it harder to quit smoking'

  • Comment
Sleep deprivation, exacerbated by shift work, can make it harder for student nurses to quit smoking, according to a German study.

Sleep deprivation, exacerbated by shift work, can make it harder for student nurses to quit smoking, according to a German study.

Researchers followed 500 student nurses who smoked at the start of the study. After a year, 53 had given up.

They found that for every extra hour slept per night the probability of quitting increased by one and a half times.

The authors admitted that nurses' sleep patterns were influenced by the 'professional need for shift work'. But they added: 'Advice to go to bed earlier may increase the probability of a successful smoking cessation attempt.'
