The most accurate reason for the warning against strenuous exercise in very hot and humid conditions is:

**It can elevate the heart rate to unhealthy levels.**

Exercising in extreme heat and humidity can lead to heat-related illnesses such as heat exhaustion or heat stroke, as the body struggles to regulate its temperature. This can cause the heart rate to increase significantly, putting additional strain on the cardiovascular system.
