Posture affects standing and not just the physical kind

Poor posture not only affects your physical health, creating problems such as back and neck pain, breathing limitations and digestive problems; it can also affect your emotional and social well-being. 

A distraught wife begged me to write about the importance of good posture. “My husband sits for many hours a day slouched over his computer,” she said. “I’ve told him repeatedly this is bad for his body-he should sit up straight- but he pays no attention to me. He reads you every week. Maybe he’ll listen to you.”
So here goes: yes, dear sir, listen to your wife. Slouching is bad. It’s bad not only for your physical health, but also for your emotional and social well-being. More about this in a bit.
Without delay, get that computer on a proper surface and get a supportive chair that enables you to sit up straight with your head aligned directly over your shoulders and hips when your eyes are on the screen.

As a short person who is prone to back pain, I have long been aware of the value of good posture and seating that minimizes the stress on my spine and the muscles and ligaments that support it.

Poor posture can have ill effects that radiate throughout the body, causing back pain and neck pain, muscle fatigue, breathing limitations, arthritic joints, digestive problems and mood disturbances. It can also create a bad impression when applying for a job, starting a relationship and making new friends.

Poor posture can even leave you vulnerable to street crime. Many years ago, researchers showed that women who walked sluggishly with eyes on the ground, as if carrying the weight of the world on their shoulders, were much more likely to be mugged than those who walked briskly and purposely with head erect.

We live in a gravitational field, and when our bodies are out of line with the vertical, certain muscles will have to work harder than other to keep us upright. This can result in undue fatigue and discomfort that can outlast the strain that caused them.

In a study of 110 students at San Francisco State University, half of whom were told to walk in a slumped position and the other half to skip down a hall, the skippers had a lot more energy throughout the day.

Any respective or prolonged position “trains” the body muscles and tendons to shorten or lengthen and places stress on bones and joints that can reshape them more or less permanently just as walking in high heels can shorten and tighten the Achilles tendons and calf muscles, slouching while sitting hour after hour can result in a persistent slouch, while standing and walking while slouched can lead to permanently rounder shoulders and upper back.
Although early humans spent most of their waking hours walking, running and standing, today in developed countries, 75 percent of the work is performed while sitting. Most people sit going to and from work and while relaxing after work. The longer people sit or stand without a change in position and movement, the more likely they will be to develop a postural backache, according to a report in The Journal of Manipulative and Physiological Therapeutics.

“Text neck,” a term coined by a Florida chiropractor, Dean L. Fishman, is a repetitive stress injury resulting from hours spent with the head positioned forward and down while using electronic devices. This leads to tight muscles in the back of the neck and upper back. And those who lean forward while sitting may be inclined to clench their jaws and tighten their facial muscles, causing headache and TMJ- temporomandibular joint syndrome.
Leaning forward or slouching can also reduce lung capacity by as much as 30 percent, reducing the amount of oxygen that reaches body tissues, including the brain, according to Dr. Rene Cailliet, a pioneer in the field of musculoskeletal medicine who died in March.

Additionally, slouching or sitting in a scrunched position compresses the abdominal organs and may reduce peristaltic action that is important to normal digestion and bowel function.

One of today’s most troublesome activities, especially for children and adolescents whose bone structure is still developing, is carrying extraordinarily heavy backpacks to and from school and often throughout the school day. The weight forces them to bend forward, with potentially the same consequences as slouching.

Among other postural habits to avoid are these, listed by Britain’s National Health Service.
1. Standing with a flat back, with the pelvis tucked in and lower back straight.
2. Standing with chest pushed forward and buttocks pushed back.
3. Leaning on one leg, which puts undue pressure on one side of the lower back and hip.
4. Bending the head back and sticking out the chin while looking at a computer screen or television. Instead, lower the screen or raise the seat.
5. Holding the phone on a shoulder. Instead, use a hands-free device like a headset or Bluetooth.

Improving posture requires a conscious effort and often strengthening and flexibility exercises to correct muscular imbalances, according to Nick Sinfield, a British physiotherapist. For example, exercises that strengthen the core, buttocks muscles and back extensors help correct a slouching posture, he said.
