Question

At which of the following WGBT (wet bulb globe temperature) temperatures should a client avoid exercise due to hot and humid conditions?

1) 25°C
2) 30°C
3) 35°C
4) 40°C

Answer 1

Clients should exercise extreme caution and avoid strenuous activities at a WGBT of 30°C and above, with 40°C posing a significant risk to health. It is important to follow WGBT advisories and adjust exercise routines to prevent heat-related illnesses.

Step-by-step explanation:

In regards to the question about WGBT (wet bulb globe temperature) and exercise, clients are generally advised to avoid strenuous activities in extreme heat conditions to prevent heat-related illnesses. The specific WGBT at which exercise should be avoided can vary based on several factors including acclimatization, hydration, and fitness levels, but extreme caution should be taken at temperatures of 30°C and above. At 40°C, exercise poses a significant risk to health due to the potential for heatstroke and other heat-related illnesses, and it is highly recommended that exercise be avoided at these temperatures. It is essential for individuals to pay close attention to WGBT advisories and adjust their exercise routines accordingly.

The WGBT is a composite temperature used to estimate the effect of temperature, humidity, wind speed, and solar radiation on humans. It's extensively used by industrial hygienists, athletes, and military personnel to determine exposure levels to high temperatures.
