What temperature range is considered vigorous tissue temperature?

• A. 40-45 degrees Celsius
• B. Less than 40 degrees Celsius
• C. Greater than 45 degrees Celsius
• D. 37 degrees Celsius

Answer: (A)

Vigorous tissue heating is reached when tissue temperature climbs into roughly 40–45°C. At this level, metabolic activity accelerates and blood flow increases, while collagen-containing tissues become more pliable, enhancing tissue extensibility and producing notable analgesic effects. This range provides a strong therapeutic stimulus without pushing temperatures into the danger zone where proteins can denature or deep tissue burns become likely; temperatures above 45°C raise safety concerns, and below 40°C generally yields only mild to moderate effects. That’s why 40–45°C is considered the vigorous range.
