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.
