A British study found that more than half of those surveyed reported poor or interrupted sleep when sleeping with their spouse on weekdays.

Experts surveyed more than 15,000 people and found that more than a quarter of participants (about 27%) admitted that they slept better when sleeping alone, and 8% even considered sleeping in separate beds to get a better night's sleep. Notably, up to 55% of survey participants revealed that the most annoying thing about sleeping in the same bed was their partner snoring.

According to sleep experts, lack of sleep and stress caused by snoring seriously affect couples and their family life.

People may be more likely to argue when they are tired or stressed, says Sammy Margo, a British sleep therapist and author of several books on sleep. Additionally, fatigue can lead to misunderstandings or misinterpretations, which can also contribute to arguments.

However, there is a simple solution to prevent these arguments: go to bed 90 minutes apart, according to the New York Post.

Margo says 90 minutes is the “optimal amount of time,” because one person will be in a deep sleep phase before the other gets into bed. “This way, you get the benefits of intimacy from sharing a bed with your partner, but you don’t have to struggle to fall asleep next to them,” the New York Post reports.
