Sleep loss of just two hours in a night can make you an angrier person, a study reveals. Research from Iowa State University shows that people who lose just a few hours of sleep at night are angrier and less capable of adapting to frustrating situations than people who get adequate rest.

Earlier, researchers have found that sleep loss raised negative emotions in people such as anxiety and sadness.

The study shows tiredness was to be blamed for 50 per cent of the experimental effect of sleep restriction on anger. This suggested individuals’ sense of sleepiness may point to whether they are likely to become angry.
