Which of the following is NOT a chemical stressor?

Chemical stressors are external chemical agents that the body must process and that can provoke a stress response, often by altering neurotransmitter systems, metabolism, or cardiovascular function. Nicotine, caffeine, and alcohol fit this idea because they are ingested substances that act on the body's chemistry and can trigger measurable stress-related effects. Oxygen, on the other hand, is a fundamental requirement for cellular energy production and a normal part of the environment. While very high levels of oxygen can cause oxidative stress, in this context it’s not treated as a chemical stressor like a toxin or drug; it’s a basic physiological substrate. Therefore, oxygen does not belong in the category of chemical stressors.
