Does your back hurt? Do you feel tired after sitting all day? If so, these symptomsmight have something to do withhow you sit. The way a person sits in a chair is important. This is especially true for people like students and office workers who sit for long hours.
Harvard University and other instituteshave carried out research on the effects of poor posture. These effects are not just limited to back and neck pain. Poor posture puts extra stress on musclesand joints. This leads to fatigue, chronicpain, and even damageto small muscles in the arms, hands, and legs. This can result in injuriesor medical disorders. Studies also show that poor posture can prevent the blood in our bodies from flowing properly.
Sitting slouched is also bad for our digestion. Slouching makes it harder for food to move through the digestivesystem, which can cause heartburn. It also makes our bodies unable to absorbnutrientswell. Leaningforward in our chairs can be bad for our bodies as well. This position can make us press our teeth together, which can lead to jawpain and headaches.
