The Sleep Council, which aims to raise awareness of the importance of good sleep, found 24 per cent of men said they never woke up grumpy, compared with only 14 per cent of women. It also found 13 per cent of women stayed in a bad mood for two to four hours, while 10 per cent of men did the same.
But look:
Almost a third of women blamed their partner’s snoring for their trouble sleeping.
