A new survey has found women are getting more sleep than men.
Women get an average of 8 hours a night, compared to 7 hours by men.
Two-thirds of men said they needed less sleep than their female partners, and they tended to get up earlier.
The survey of 2-thousand adults found 63 per cent of couples said sleep had caused 'tensions' in their relationship, with one in 10 having separate bedrooms.
A spokesperson for, Naturecan who conducted the survey said:
"We all know how crucial good sleep is to our overall well-being."
"These results show that we are sleeping less, particularly during these hot summer months, and many couples have completely different sleep patterns."
"Sleep imbalances can cause big problems in a relationship because intimacy inevitably suffers when we are not in bed together."
