Heat vs Cold Therapy
Depending on the injury or condition, doctors recommend no more than 20 minutes of either heat or cold therapy. This treatment is a highly effective, drug-free way to relieve pain and inflammation. Many people are uncertain as to what treatment is best.
Any cold treatment should be used for 24 to 48 hours after an injury.  Using COLD immediately after an injury or physical trauma constricts blood flow and may help:   
  • Reduce swelling, bruising and muscle spasms
  • Alleviate headaches
  • Soothe muscles after sports or workouts
Many doctors recommend the R.I.C.E (Rest, Ice/Cold, Compression, and Elevation) method for injury prevention and recovery. 
Using HEAT at least 24 hours after an injury increases blood flow, supplies oxygen and nutrients, and may help:
  • Relax muscles and provide comfort for cramping
  • Soothe arthritic or aching joints
  • Relax tight muscles
