Which of the following is one of the four Regen stressor categories?

• A. Nutrition
• B. Technology use
• C. Environment
• D. Genetics

Answer: (C)

Regen stressor categories group different sources of stress to help you see where the load is coming from. The environment category covers external conditions you encounter—things like air quality, temperature, noise, crowding, housing quality, and exposure to toxins—that require your body to adapt. This is why it’s the best pick here: the prompt is pointing to an external context rather than something internal or behavioral. Nutrition focuses on what you consume for energy and resources, genetics on inherited traits, and technology use on how digital activity adds to cognitive or behavioral load. Recognizing environment as one of the four categories helps you place the stressor in the right domain and understand how external surroundings influence regulation and performance.
