Why Sitting is One of the Worst Things We Do for Our Bodies (And What You Can Do About It)
If you spend most of your day sitting at a desk, driving, or relaxing on the couch, you're not alone. The average adult now spends between 8–10 hours sitting each day, and while it may feel harmless, prolonged sitting can have a significant impact on your muscles, joints, posture, and overall health.
At our physiotherapy clinic in Cromwell, one of the most common things we hear is:
"My back is sore after work."
"My neck feels stiff every afternoon."
"My hips always feel tight."
More often than not, prolonged sitting is playing a major role.
Why is Sitting So Bad?
Our bodies were designed to move.
Muscles, joints, and connective tissues rely on regular movement to stay healthy. When we remain in one position for long periods, our bodies begin to adapt and unfortunately, not in a good way.
1. Your Hips Become Tight
When sitting, your hip flexors stay in a shortened position for hours. Over time, they become tight and stiff.
This can contribute to:
Lower back pain
Hip pain
Reduced walking or running efficiency
Poor posture
2. Your Glutes "Switch Off"
Your glute muscles are some of the strongest muscles in your body, but prolonged sitting means they aren't being used.
Weak or inactive glutes can lead to:
Lower back pain
Knee pain
Poor balance
Increased risk of injury during exercise
3. Increased Pressure on Your Spine
Many people think standing is harder on the back than sitting, but sitting actually places more pressure through the discs of the lumbar spine.
Slouching increases this pressure even further and can contribute to:
Disc irritation
Sciatica symptoms
Persistent lower back pain
Neck and shoulder tension
4. Your Neck Pays the Price
Looking down at laptops or leaning towards computer screens encourages a forward head posture.
For every few centimetres your head moves forward, your neck muscles have to work significantly harder to support it.
This often leads to:
Neck pain
Headaches
Shoulder tightness
Reduced movement
5. Reduced Circulation
Remaining still decreases blood flow to your muscles and legs.
You may notice:
Swollen ankles
Heavy legs
Muscle stiffness
Reduced energy throughout the day
Movement acts like a pump, helping circulate oxygen and nutrients to the tissues that need them.
The Good News: You Don't Need to Stop Sitting
The problem isn't sitting itself.
The problem is sitting for too long without moving.
Even people with desk jobs can significantly reduce their risk of pain simply by adding more movement into their day.
Five Simple Ways to Combat the Effects of Sitting
1. Follow the 30-Minute Rule
Aim to stand up every 30 minutes.
You don't need a long break even 1–2 minutes can make a difference.
Try:
Walking to refill your water bottle
Standing during phone calls
Walking to speak to a colleague instead of emailing
Your spine loves variety.
2. Stretch Your Hip Flexors
A simple kneeling hip flexor stretch can help reverse hours spent sitting.
Hold for 30 seconds each side, repeating 2–3 times throughout the day.
Your hips (and lower back) will thank you.
3. Strengthen Your Glutes
Some excellent exercises include:
Glute bridges
Squats
Step-ups
Monster walks with a resistance band
Single-leg balance exercises
Strong glutes help support your back, hips and knees.
4. Improve Your Workstation
You don't need a fancy ergonomic setup, but a few adjustments can make a big difference.
Check that:
Your screen is at eye level.
Your feet are flat on the floor.
Your elbows rest around 90 degrees.
Your shoulders stay relaxed.
Your chair supports your lower back.
Remember, even perfect posture becomes poor posture if you stay there too long.
5. Exercise Outside of Work
Regular exercise helps undo many of the effects of prolonged sitting.
Walking, cycling, swimming, strength training or Pilates are all excellent choices.
Aim for at least 30 minutes of movement most days of the week.
Does Good Posture Matter?
Yes but perhaps not in the way many people think.
There isn't one "perfect" posture.
The healthiest posture is your next posture.
Changing positions regularly is more important than trying to sit perfectly all day.
When Should You See a Physiotherapist?
If you're experiencing ongoing:
Back pain
Neck pain
Shoulder pain
Hip stiffness
Sciatica
Headaches related to posture
it may be time to seek professional advice.
A physiotherapist can assess how your body is moving, identify contributing factors, and develop a personalised treatment plan that addresses the root cause not just the symptoms.
Treatment may include:
Hands-on therapy
Exercise prescription
Postural advice
Strengthening programmes
Ergonomic assessment
Education to help prevent the problem returning
