As far as sleep is concerned, it is always better to sleep with someone by your side. At least that is what these studies try to convey to us as they compare the life of a single woman to a married one and how a good marital relationship can produce good sleep.
When it comes to the difference between single and married, a lot of things come into mind. One factor is that of the security issue. Single women often have a lot of things in their mind though not necessarily marriage. They are normally the career women who would endlessly think of issues such as business thus making them unstable when sleeping. Also, the transition of single women to marriage becomes an issue as well. Adjusting to having someone beside them may not necessarily be as easy and thus contributes to the sleeping soundly problem.
For relationships, it is common sense in thinking that couples who have problems are at odds and may be encountering a silent psychological warfare when in bed. Something like is there something to discuss or hiding things from the other cannot be discounted. So when you put one and one, it is apparent that you have a lot of things in mind thus depriving you of sleep.
The data from both studies suggest that sleep and relationship happiness are closely linked. The lesson for couples, especially those who are struggling with problems, is that paying attention to sleep habits may help solve other issues in the relationship. Dr. Hasler said couples should work to resolve problems before bedtime and avoid discussing difficult topics when one or both have not slept well.
