Stressors can originate from both external and internal sources. External stressors refer to environmental factors such as noise, pollution, or social conflicts. Internal stressors, on the other hand, can be psychological or emotional in nature, such as self-imposed pressure, excessive worrying, or negative thinking patterns. Both types of stressors can contribute to an individual's experience of stress and trigger stress responses.
