Prevention

Prevention

Our joints and spine serve us for decades, and much of their condition depends on everyday habits: how much we walk, how we sit, how we lift and how we sleep. This plan is not a treatment; it helps you build a sensible routine that is easy to keep up.

Joints prefer movement to rest. The best care for your back is not a perfect posture but changing position often.

— Editor's note

What you'll need

  • A notebook or a note on your phone for short entries
  • Comfortable shoes for walking
  • A clear stretch of wall for checking your posture
  • A chair on which your feet rest flat on the floor
  • A phone reminder for breaks
  • A willingness to change habits gradually rather than all at once
  1. Take a look at your typical day

    For a few days, simply note how much time you spend sitting, standing and moving. Without this picture it is hard to know where to start.

    Hypothetical example: the notes show that the whole working day is spent at a desk, and the only walk is the one to the bus stop.

  2. Get up more often

    Take a short movement break every time your reminder goes off: walk around the room, stretch, change position.

    Hypothetical example: someone sets a phone alert as a cue to pause and goes to fetch water themselves instead of asking a colleague.

  3. Add some walking

    Walking is the most accessible form of exercise for the leg joints and back muscles. Increase it little by little, guided by how you feel.

    Hypothetical example: part of the journey home is done on foot, and catch-ups with friends move from a café to a park.

  4. Set up your workspace

    Your feet should rest on the floor, the screen should be roughly at eye level, and the things you use often should be within arm's reach.

    Hypothetical example: a stack of books goes under the laptop, and a separate keyboard means no more leaning forward.

  5. Lift heavy things wisely

    Keep the load close to your body, bend your knees rather than just your back, and avoid twisting sharply while carrying something. Heavy loads are better split into several parts.

    Hypothetical example: shopping is packed into two bags, one for each hand, instead of one heavy bag over the shoulder.

  6. Come back to your posture

    Several times a day, recall the position against the wall: the top of your head reaching up, shoulders relaxed, chin not pushed forward.

    Hypothetical example: the posture check is tied to a routine moment, such as waiting for the lift.

  7. Look after your sleep

    During sleep the back muscles rest. A comfortable mattress and a pillow that supports your neck help you wake up without stiffness.

    Hypothetical example: someone notices they sleep better on their side with a pillow of the right height and stops dozing off on the sofa.

Common mistakes

  • Trying to change everything in one day and giving up a week later
  • Sitting still in a "perfect" posture instead of changing it more often
  • Jumping into intense workouts after a long break
  • Putting up with pain and continuing the activity that caused it
  • Relying on miracle products from adverts instead of habits and a doctor
  • Avoiding movement for fear of doing harm when a doctor has not ruled it out

If it doesn't work out

  • If you can't get out for walks, walk around your home or use the stairs
  • If your job doesn't let you stand up, change position while seated and stretch without getting up
  • If it's hard to remember your posture, link the check to an everyday action
  • If motivation is low, get moving together with someone close to you

Check yourself

  • You know how much of your day you spend sitting
  • You get up and move during the working day
  • Regular walking is part of your routine
  • Your workspace is adjusted to your height
  • You lift heavy things holding them close to your body
  • You remember what upright posture against a wall feels like
