The Spine: The "Second Lifeline"
As the central support of the body, the spine protects the spinal cord and connects the brain to the rest of the body.
1. Golden Rules for Daily Posture
- Sitting: Use lumbar support. Keep feet flat and screen 10cm above eye level. Avoid crossing legs.
- Standing: Shoulders down, chin tucked, weight evenly distributed.
- Sleeping: Medium-firm mattress. Use pillows to support natural curves (under waist for back sleepers, between knees for side sleepers).
2. Core Strengthening Exercises
Recommended 3-4 times weekly:
- Bird-Dog / Modified Superman: Strengthens back extensors.
- Plank: Stabilizes the core to protect the lumbar spine.
- Glute Bridge: Relieves lower back strain by strengthening glutes.
3. Ergonomic Safety Tips
Lifting Heavy Objects: Squat, don't bend! Keep the object close to your body and lift with your legs.
Temperature: Keep your neck and lower back warm to prevent muscle stiffness.
4. Habits to Avoid
- Looking down at phones for long periods (exerts 27kg of pressure on the neck).
- Carrying heavy bags on a single shoulder.
- Chronic sedentary behavior with poor posture.
Summary: Prevention is key. Combine correct posture, moderate exercise, and scientific rest to safeguard your spine.
