It’s quite fascinating to know that as you are sleeping alone on a queen sized mattress, you may occupy the whole bed for your self. Same as when you are sleeping on a sofa, your body will try to move away from the edge of the sofa. This phenomenon had puzzled scientist for a long time.
They believed the brain can remember the spacing as well as the size of the bed. Therefore, it subconsciously directs the body away from the edge of the bed. This prevents us from falling off the bed.
However if you are not sleeping on your own bed, you may fall off the bed. This is why hospitals have beds with rails at the side. Likewise for young children’s bed because their brain is still developing.
