When to Use

Pre-participation screening for outdoor athletic events (e.g., football, soccer, marathon, tennis) to assess heat stress risk.

Real-time monitoring during training sessions or competitions in hot and humid environments to guide activity modifications.

Surveillance of environmental conditions for military training, firefighting, or occupational settings with high heat exposure.

Implementation of heat illness prevention protocols in accordance with ACSM, NCAA, and NATA guidelines.

Determination of work-to-rest ratios, hydration breaks, and cooling strategies based on ambient heat stress.

Key Indication - Heat Stress Risk Stratification

The WBGT (Wet Bulb Globe Temperature) is the gold-standard environmental index for assessing heat stress during physical activity. The American College of Sports Medicine (ACSM) recommends using WBGT to stratify risk of exertional heat illness (EHI) and guide activity modifications. A WBGT ≥ 28°C (82.4°F) indicates high risk, with mandatory rest breaks and close monitoring; ≥ 32°C (89.6°F) signals extreme risk, warranting cancellation or postponement of vigorous activity.

When Not to Use / Contraindications

Indoor environments with controlled temperature and humidity (use standard temperature/humidity indices instead).

Individual athlete-specific heat tolerance assessments (WBGT is environmental, not personal; use heat tolerance testing for individuals).

Scenarios where direct solar radiation is absent (e.g., night events under lights; WBGT may overestimate risk).

When accurate measurement equipment (e.g., WBGT meter) is unavailable; use alternative indices like heat index with caution.

For predicting heat illness in cold or temperate climates (WBGT is designed for hot conditions).
