Tips for preventing back pain

Why does the spine make us suffer?

The spine consists of a stack of rigid vertebrae between which soft parts are slid. These soft parts between the vertebrae are called intervertebral discs. Thanks to them we can move and jump without hurting ourselves.

If these soft parts are deformed beyond a critical threshold they can cause back pain such as low back pain or nec
k painSA because of them I can also feel back pain in other parts of the body. If for example the lower intervertebral discs are damaged by a herniated disc the root of the sciatic nerve can be pinched when I move and the resulting inflammation causes pain from the buttock to the foot.

You understand that it is important to take care of your intervertebral discs by adopting a good sitting position, which preserves the natural shape of the S-shaped spine.

The good news is that it is easy to identify a bad sitting position.
Indeed, the natural shape of the spine reveals two hollows at the lumbar and cervical levels. If these troughs disappear for a long time it means that intervertebral discs are compressed and you risk back pain.

Sitting in a chair

You sat too far ahead in a chair. So that the back can lean against the back you round the backThe
solution is simple:
1- Sit well at the bottom of the seat so that the lower back is leaning against the bac
k.2- adjust the height of the seat so as not to slide
forward3- if the chair has armrests adjust the highs enough for them to help you sit straight , but not too much not to shrug (apply the same rule for office height)

Sitting on a sofa or chair

The seat of a sofa or armchair is too deep if you are less than one metre tall. So you can’t press your lower back against the back.
The solution: Add a cushion against the backrest to reduce the depth of the se
at attention: it is important to add enough thickness so that the hollow behind the knee is not pressed against the seat. Otherwise the blood flows less well.

For the grown-ups

You are more than eighty metres tall and the seat is usually too small.
You will be able to press your back properly against the back.
But there’s a good chance the armchair armrests are too low and your knees are too high.
There is no pressure under the thighs and the entire upper body weight rests on your hamstrings; you end up having a sore buttocks

Too low a seat is quickly uncomfortable due to over-pressure in the hamstrings

Preventing back pain: the bespoke chair

The solution to prevent back pain: adapt the chair to your body by opting for a custom chair, the only one that will be perfectly suited to your body.
Measure yourself to choose a depth and seat height adapted to your morphology.
Choose a seating angle based on activity.
For cushions opt for a firm seat (e.g. 40 kg/m3 40 kg/m3 6 cm thick foam) and for the backrest a slightly softer foam (e.g. a 35 kg/m3 Bultex).
By combining a soft foam and a firm foam you can even create a lumbar support.

Back pain installed: the bespoke rocking chair

Back pain is installed: try a custom rocking chairIn
1955, a doctor prescribed Kennedy for his back swimming and the use of a rocking chair. In 1961 Kennedy was elected president in 1961 and was quick to install one in the Air Force On and Camp David. He even offers rocking chairs to his friends, family and heads of state.
