Bad sleep definitely affects me, even after one night. The effects seem to build, and the longer I go without a good night of sleep, the harder it is to get back into a good routine.
Sleep is so important for our physical and mental wellbeing - something which is often taken for granted.
Researchers recruited more than 3,700 university students across the UK who had reported problems sleeping and randomised them into two groups. One group received six sessions of online CBT (cognitive behavioural therapy) aimed at improving their sleep; the other group got standard advice. Ten weeks into the study, the students who received CBT reported a halving in rates of insomnia, accompanied by significant improvements in scores for depression and anxiety, plus big reductions in paranoia and hallucinations. Daniel Freeman, professor of clinical psychology at Oxford University, who led that study thinks one of the reasons why sleep deprivation is so bad for our brains is because it encourages repetitive negative thinking. The positive side of this research is it implies that helping people get a good night's sleep will go a long way to helping improve our sense of well-being.
