Pool Exercises for Joint Pain: Aquatic Therapy You Can Do Yourself

Why Water Works

Water is magic for painful joints. When you're submerged:

  • **Chest-deep:** 60-75% less weight on joints
  • **Waist-deep:** 50% less weight
  • **Neck-deep:** 90% less weight
  • This means you can exercise with far less pain while still building strength and endurance.

    Benefits of Aquatic Exercise

  • Reduced joint stress and pain
  • Improved strength (water provides resistance)
  • Better cardiovascular fitness
  • Increased flexibility
  • Improved balance
  • Decreased swelling (hydrostatic pressure)
  • Pain relief (warm water relaxes muscles)
  • Who Benefits Most

  • Arthritis (osteoarthritis and rheumatoid)
  • Back pain
  • Hip and knee replacements (post-surgery)
  • Fibromyalgia
  • Obesity (low-impact option)
  • Balance problems
  • Anyone with joint pain during land exercise

  • Ideal Water Temperature

  • **Therapy pools:** 92-96°F (best for arthritis)
  • **Standard pools:** 78-84°F (fine for most exercise)
