How many protective layers are recommended for thermotherapy?

• A. 2-4 protective layers
• B. 4-6 protective layers
• C. 6-8 protective layers
• D. 8-10 protective layers

Answer: (C)

The key idea is protecting the skin from burns when applying heat therapy by using a proper barrier thickness. Six to eight layers of protective barrier is recommended because it provides enough insulation to prevent excessive surface heating while still allowing the therapeutic heat to reach underlying tissues. Too few layers can let heat be too intense on the skin, increasing burn risk, whereas too many layers can insulate too much and diminish the heating effect. Always tailor to the device and patient tolerance, and check the skin for any adverse reactions during treatment.
