Why Sleep Position Matters

You spend 6-8 hours in one position. Poor positioning:

Strains joints and muscles

Compresses nerves

Prevents healing

Causes morning pain and stiffness

Good positioning:

Maintains neutral spine

Reduces pressure points

Supports healing

Improves sleep quality

General Principles

Spine Alignment

Your spine should maintain its natural curves. Avoid:

Excessive twisting

Prolonged bending

Asymmetric positions

Pillow Support

Use pillows to fill gaps and support curves:

Under/between knees

Under waist

Proper neck support

Mattress Matters

Medium-firm generally best

Should support, not sag

Replace every 8-10 years

Personal preference factors in

Positions for Back Pain

Best: On Back with Knee Support

Lie on back

Pillow under knees

Small rolled towel under low back curve (optional)

Keeps spine neutral

Good: Side-Lying with Pillow Between Knees

Lie on side

Pillow between knees (keeps pelvis aligned)

Slight bend at hips and knees

Maintain spine alignment

Avoid: Stomach Sleeping

Forces neck rotation

Increases lumbar curve

If you must: pillow under pelvis, no pillow under head

Positions for Neck Pain

Best: On Back

Pillow that supports neck curve

Head neutral (not pushed forward or back)

Consider cervical pillow

Good: Side-Lying

Pillow fills space between shoulder and head

Neck stays aligned with spine

Avoid thick or thin pillows

Avoid

Stomach (forces rotation)

Too many pillows (pushes head forward)

Arm under head (strains shoulder and neck)

Pillow Selection

Back sleeper: Lower, supports neck curve

Side sleeper: Higher, fills shoulder-to-head gap

Combo: Adjustable or medium height

Positions for Hip Pain

Bursitis/GTPS (Outer Hip Pain)

Avoid: Sleeping on painful side

Best:

Sleep on non-painful side

Pillow between knees (essential)

Pillow under top leg for extra support

Or: Back sleeping with pillow under knees

Hip Arthritis

Options:

Side-lying with pillow between knees

Back with pillow under knees

Avoid positions that compress or rotate hip

After Hip Replacement

Follow surgeon's specific instructions

Usually avoid crossing legs

Pillow between knees

May need to avoid side-lying initially

Positions for Shoulder Pain

General Rules

Don't sleep on painful shoulder

Avoid arm overhead positions

Support arm if needed

Best Positions

Back:

Arm at side or on pillow

Small pillow under arm keeps shoulder neutral

Non-painful side:

Pillow to hug (supports painful arm)

Keeps shoulder in neutral position

Rotator Cuff/Impingement

Sleeping on painful side often worsens

May need recliner for severe cases

Slight incline can help

Frozen Shoulder

Experiment with positions

Pillows for arm support

Whatever allows sleep with least pain

Positions for Sciatica

Disc-Related

Best: On back, knees elevated (pillow under)

Good: Side-lying, knees bent, pillow between

May help: Slight recline (pillows or adjustable bed)

Stenosis-Related

Best: Side-lying, knees drawn up (fetal-ish)

May help: Back with significant knee elevation

Avoid: Flat on back (extends spine)
