If you want a good night’s sleep, don’t go to bed angry
MOST couples know you should never go to bed on an argument. But anger won’t just harm your relationship – it could also ruin your sleep, researchers claim.
A study has found those who were angry generally, and struggled to keep their temper, slept worse.
They are believed to keep themselves awake by dwelling on their frustrations and find it harder to achieve the calmness they need to drop off. There may even be a physical reason, as feelings of anger increase cardiovascular activity, which makes it harder to fall asleep.
Psychologists from Iowa State University based their findings on 436 volunteers whose sleep was monitored after completing an anger questionnaire.
Writing in the Journal Of Research In Personality, they state: ‘These findings add to the growing evidence that being prone to anger may lead to poor sleep and that anger and sleep are intimately connected.’
Study participants were asked questions designed to determine if they were quick-tempered and became angered easily.
Based on their answers, participants they were sorted into groups based on how they dealt with anger – the ‘anger-in’ group, the ‘angerout’ group and people with ‘anger-control’.
The people who controlled their anger got better quality sleep during a week of being tracked.
