The new scientific research shows that there's no need to feel guilt because of it.
Snoring, pushing or fight for a blanket are 'benefits' of sharing the bed between spouses, partners, lovers, which eventually - scientists say, may contribute to certain diseases.
The 'Independent' says that the research of the university of Leeds showed that 29 percent of the people blame their partner for their lack of sleep.
It is no secret that sleep deprivation brings bad mood and poor concentration, but research shows that it can increase the risk of developing heart diseases or diabetes.
Of course, researchers note that the lack of space in the bed is not the reason for the break-up, because on the other hand the research has shown that people in happy relationships do sleep better than single people.
The main reason for this is that they feel safer and more relaxed with their better half.
So what should you do? A kiss goodnight is a good start because 71 percent of respondents say that they sleep better after that, and almost the same effect has the message 'I love you'.
