As the night in the same bed with a partner affect sleep? Source:

to sleep and feel good, try to persuade the person that you like to sleep in the same bed.

Maybe you guys already knew about this – the results of the latest scientific researches prove that sleeping together with the partner has a positive effect on mental health, memory, concentration and problem solving skills. The researchers found that couples who every night go to sleep in the same bed was the best sleep quality, in particular it concerned the rapid phase of sleep REM (rapid eye movement) phase associated with dreams. Recall that the phase of the REM occurs 90 minutes after falling asleep and alternates between the other four stages of deep and light sleep. Poor sleep quality, on the other hand, is associated with Alzheimer's disease and depression.

Why sleep alone is good

As shown by the results of a study published in the journal , a good relationship with a partner, apparently, affect the quality of sleep. As explained by Henning Johannes Drews – the study's lead author and a postdoctoral fellow of the Center for integrative psychiatry in Germany, obtained in the course of work, the findings are a departure from conventional wisdom and previous research on how sleeping with a partner affect sleep quality. Moreover, co-sleep seem to stabilize REM sleep.

In the study, 12 couples were invited to spend the night in the sleep lab. Using polysomnography, a type of sleep study that records brain waves, movement, oxygen levels in the blood – the researchers monitored the sleep of subjects invited. The pair slept in the laboratory four nights for two weekends. In one weekend they slept in two different rooms on single beds. Next – in the same room on two seperate beds. Each couple was given two sets of sheets and two blankets.

a Good relationship between partners is a guarantee of quality and healthy sleep, and perhaps Vice versa.

When couples sleep together, they reported improvement in sleep quality. However, the researchers found no differences in such indicators as needed to sleep. However, they found that the time of REM sleep increased. It later turned out that partners who shared a bed were more likely to synchronous sleep mode. moreover, the authors found a correlation between a good relationship and synchronization of the sleep, which implies a complete connection between couples.

The Researchers see two working explanations to reduce disturbances of REM sleep, when partners sleep apart. The first explanation is a purely biological: during the phase of REM is disrupted the body's ability to regulate temperature, and therefore, hartner can help the body temperature to remain stable. The second explanation is psychological: partner maybe just to make us feel safe. Overall, a relaxing and safe environment promotes deep sleep.

But what other reasons can explain the quality of sleep in the same bed with your spouse? As the Inverse, c the one hand, it could just be that the partners just fall asleep around the same time and Wake up throughout the night, causing the lining of the sleep cycle. But even when the researchers excluded cases of night waking, they still found that 47.5% of REM in both partners was synchronized with each other.


Sleeping together, partners often move limbs compared with their colleagues. However, these increased traffic does not interfere with the sleep quality and the quality of the REM sleep remained positive and stable.

As suggested by the authors of scientific work, it is the depth of relationship may explain why sleep phase both partners are synchronized, when they are sleeping. However, this is just a trend – it cannot be completely confirmed by experimental data. Moreover, the relationship between the joint quality sleep and REM sleep has its roots in evolution. From an evolutionary point of view, sleep is definitely a social condition. If you look at many primates, more traditional society, or historical descriptions of European societies, you will see that co-sleeping – a common occurrence. Thus, for centuries, sleep and social factors were related.

Since this is a small pilot study, the data obtained is not accurate enough to apply to all. In addition, the study has several limitations, as the experiment involved only heterosexual couples. Finally, scientists believe that the sharing of beds is probably not the way to improve sleep if you have apnea, and other diseases. Still, the new results showed that the combined use of beds does not necessarily mean the lack of a good night's rest, and Vice versa.
