Sleeping together makes men stupid

When a man sleeps with his partner, even if they don't have intimate sexual relations, his sleep patterns will be disrupted, which in turn will affect his performance on a mental agility test the next day.

However, women do not face this problem. Researchers say that although women's sleep patterns may be disrupted when they share a bed with their loved ones, they tend to enjoy better quality sleep when they do fall asleep. This means that their brain power has not been reduced.

Sleeping together will make men dumber the next day

The research team recruited eight young couples who were not yet married and had no children. The young couples were asked to sleep in separate beds for 10 nights and together for 10 nights, and their sleep patterns were monitored via wrist monitors and sleep diaries. And the next day they were tested on their thinking or cognitive abilities.

The results showed that even if the couple did not have intimate sexual relations, sleeping in the same bed would still disrupt the sleep of both partners compared to sleeping in separate beds, but only men would suffer from the mental impact. This may be because lack of sleep causes men's stress hormone levels to rise, which in turn impairs their ability to complete simple cognitive tests the next day. Women, however, do not experience the same adverse reactions as men. The researchers found that even if women sleep the same amount of time as men, they will be much more energetic than men the next day. The researchers therefore concluded that women must sleep more soundly and have better sleep quality.

Sleeping in the same bed also affects dreams

In addition, the study also found that sleeping in the same bed also affects dreams. Generally, women will remember more dreams after sleeping in separate beds, while men will remember more dreams after sleeping in separate beds. A recent study by Austrian scientists shows that sleeping in the same bed with a lover will have an adverse effect on his brain power the next day, while this will not happen to women.
