There is no scientific evidence to suggest that sleeping in a specific position can increase your height.
Your height is primarily determined by genetics and influenced by factors like nutrition and overall health. Sleeping positions can be comfortable and promote good sleep hygiene, but they don't directly impact your growth.
While some believe that sleeping on your back with your legs straight can help with height, there's no scientific basis for this belief.
Focus on maintaining a healthy lifestyle, including proper nutrition, regular exercise, and adequate sleep, to optimize your growth potential.
