It is time for you to check your posture.
Does your back hurt? Do you feel tired after sitting all day? If so, these symptoms might have something to do with how 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 institutes have 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 muscles and joints. This leads to fatigue, chronic pain, and even damage to small muscles in the arms, hands, and legs. This can result in injuries or 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 digestive system, which can cause heartburn. It also makes our bodies unable to absorb nutrients well. Leaning forward in our chairs can be bad for our bodies as well. This position can make us press our teeth together, which can lead to jaw pain and headaches.

= That’s the way (in which) Hank handled the problem.

例: Anna doesn’t know the way how we do things in our office. (╳)
→ Anna doesn’t know how we do things in our office. (○)
= Anna doesn’t know the way we do things in our office. (○)

是時候檢查自己的姿勢了。
你的背痛嗎?坐了一整天你是否會感到疲倦呢?如果是這樣,這些症狀可能與你的坐姿有關。一個人如何坐在椅子上很重要。對於長時間坐著的學生和上班族等人來說尤其重要。
哈佛大學和其他機構對不良姿勢的影響進行了研究。這些影響不僅限於背部和頸部疼痛。不良姿勢會對肌肉和關節造成額外的壓力。這會導致疲勞、慢性疼痛,甚至手臂、手和腿的小肌肉受損。這可能會導致受傷或疾病。研究還表明不良姿勢會阻礙我們體內的血液正常流動。
低頭垂肩地坐著也不利於我們的消化。駝背會使食物更難通過消化系統,從而導致胃灼熱。這也使我們的身體無法很好地吸收營養。坐在椅子上前傾也會對我們的身體有害。這個姿勢會讓我們咬牙,導致下顎疼痛和頭痛。
