Which side of the bed you sleep on is a matter of personal preference and habit, and there is no one-size-fits-all answer. However, some studies suggest that the side of the bed you choose to sleep on may reveal something about your personality. For example, people who sleep on the left side of the bed are said to wake up happier and better equipped, while those who sleep on the right side of the bed feel relaxed instead of stressed.
Its worth noting that choosing a side isn't just about left or right, but also about what kind of habits you are developing. According to a survey conducted by Saatva Mattress, more Americans sleep on the right side of the bed than the left, with more men than women preferring this side. However, the survey also found that 40 percent of adult Americans have always slept on the same side of the bed, and more than half report they did not consciously pick their side.
