Good posture has been recommended by orthopedics since long.
With desk jobs becoming more the norm of today, good posture is more relevant than ever. Some tips for a healthy spine are here for your rescue. Pull your chin back in line with your body. Keep your shoulders in relax position by bringing your chest forward. Sit with your knees slightly lower than your hips.
Do not cross your legs as this causes poor circulation. Always support your fore arm while typing and do not keep your spine ramrod straight.
Practicing good posture will enable you to appear confident, get a clear picture of things around you, optimizes breathing and circulation, reduces pains and aches and prevents injuries.
