3 Ways Your Body Will Thrive by Improving Posture
Leaning over with poor posture compresses your lungs and decreasing breathing volume. Shallow breathing causes less oxygen to be taken into your system, resulting in lower energy levels. Exercises such as yoga, pilates and meditation with static holding positions will help make a good neutral position seem more natural.
Good posture means your bones are properly aligned and your muscles, joints and ligaments the way they’re meant to. By allowing your vital organs to be in the correct position, supported well by properly aligned muscles, joints and ligaments, this will allow them to function at peak efficiency.
Having good posture is an instinctive non-verbal way of presenting yourself to the world in a dominant, robust way. Holding your body in "high-power" positions can summon an extra surge of power and sense of well-being when it's needed, according to Harvard Business School professor Amy J.C. Cuddy.
