Good posture is more than standing up straight, but about making sure you hold your body correctly to prevent pain, injuries or other health problems.
There is Dynamic Posture, how we hold ourselves when we are moving, walking, running or bending over to pick something up and there is Static Posture which is how we hold ourselves while we are not moving (like sitting, standing or sleeping). It is important to have both good static and dynamic posture.
Be mindful of your posture during everyday activities, like watching television, washing dishes, or walking
Stay active. Any kind of exercise may help improve your posture, but certain types of exercises can be especially helpful. They include yoga, tai chi, and other classes that focuses on body awareness. It is also a good idea to do exercises that strengthen your core (muscles around your back, abdomen, and pelvis).
Maintain a healthy weight. Extra weight can weaken your abdominal muscles, cause problems for your pelvis and spine, and contribute to low back pain. All of these can hurt your posture.
Wear comfortable, low-heeled shoes. High heels, for example, can throw off your balance and force you to walk differently. This puts more stress on your muscles and harms your posture.
Make sure work surfaces are at a comfortable height for you, whether you’re sitting in front of a computer, making dinner, or eating a meal.
When sitting , it is as equally important to maintain a health posture. Switch sitting positions often, take brief walks, stretch briefly, make sure both feel touch the floor, relax your shoulders, keep elbows in close to your body. Be sure to have back, thigh and hips supported as well (utilizing a back pillow can be helpful).
When standing, stand up straight and tall, keep your shoulders back, pull your stomach in and keep the weight on the balls of your feet. Try to keep you head level, let your arms hang down naturally at your sides and keep your feet shoulder width apart, toes pointing forward.
Practice improving your posture and you will look and feel better.
