Which condition can be exacerbated by hyperthermia during exercise?

The correct choice indicating that obesity can be exacerbated by hyperthermia during exercise relates to the physiological effects of heat on the body and how it interacts with excess weight. Hyperthermia, which refers to elevated body temperature, can impair the body's ability to regulate heat through sweating and blood flow. In individuals with obesity, the increased adipose (fat) tissue can further hinder heat dissipation and lead to greater difficulty in thermoregulation during exercise.

This can result in an increased risk of heat-related illnesses. Furthermore, exercising in a state of hyperthermia can lead to decreased exercise performance, increased fatigue, and can make physical activity less enjoyable, potentially leading to a cycle that further promotes weight gain. This highlights the importance of managing body temperature during exercise for individuals who are obese.

While conditions such as fibromyalgia, osteoporosis, and allergies can also be affected by environmental factors, their exacerbation does not have the same direct and immediate correlation with hyperthermia during exercise as it does in the case of obesity.
