Which of the following is NOT good for emotional stress?

Caffeine intake is identified as not being good for emotional stress due to its stimulating effects on the central nervous system. While moderate amounts of caffeine can enhance alertness and improve mood temporarily, excessive consumption can lead to increased anxiety, restlessness, and insomnia. These factors can exacerbate emotional stress rather than alleviate it.

In contrast, regular walking, frequent massages, and weight training have well-documented benefits for managing emotional stress. Regular walking promotes the release of endorphins, which are natural mood lifters, and can help clear the mind. Massages help to reduce muscle tension and promote relaxation, contributing to an overall sense of well-being. Weight training, while also beneficial for physical health, has been shown to improve mental health by reducing symptoms of anxiety and depression through the biochemical changes it induces, including increased serotonin levels. Thus, while the other activities contribute positively to emotional health, caffeine intake can have adverse effects.
