Summary Writing

Take Care of Your Spine (脊柱)

    The spine stands at the center of your health, providing your body with structure and support. It also contains your spinal cord, a massive collection of nerves that sends electric signals from the rest of your body to your brain. Therefore, it's important to take care of it.

    Maintaining your good posture is one of the most important things you can do to keep your spine healthy. Proper posture means standing or sitting while keeping your spine straight, except for its natural curves. Posture comes into play even when you're asleep. Sleeping on your side puts less stress on your spine than most other positions. Having a comfortable bed is also very important as sleeping in a position that isn't comfortable can leave your back feeling sore the next day.

    Exercise is also an important factor in the health of your spine. Staying still for too long—even if your posture is good—can be hard on your back. Especially if you work at a desk most of the day, it's important to get up and stretch periodically. Stretches can help the muscles around your spine relax and allow bones to shift into better positions. Strength exercises with light weights or bodyweight exercises like pushups can also help by strengthening the muscles around your spine. However, don't overdo the exercise, as repeated motions can hurt the muscles around your spine.

    Your diet also affects the health of your spine because many vitamins are necessary for bones and nerves. In particular, B vitamins help keep nerves healthy, so you may want to consider taking a supplement (补充物). Another important factor is vitamin D, which is essential for strong bones, but it's also absorbed from sunlight, so it may help to do some of those back exercises outside.
