Final answer:
Relaxation techniques, regular exercise, and adequate sleep are methods to manage stress and promote mental health, while increased caffeine intake and avoiding exercise are not advisable.
Step-by-step explanation:
Methods to manage stress and promote mental health include several beneficial practices, but not all options listed are advisable. Relaxation techniques such as meditation, deep breathing, and mindfulness can effectively reduce stress and improve mental health. Regular exercise is another proven method to not only improve physical health but also contribute to stress relief, better mood, and overall well-being. Adequate sleep is also critical for managing stress and maintaining mental health, whereas reduced sleep can exacerbate stress and negatively impact mental health. Contrary to promoting mental health, increased caffeine intake can interfere with sleep and increase anxiety; hence, it is not a recommended strategy for stress management. Similarly, avoiding exercise is not beneficial, as it can lead to sedentary behavior which is associated with an increased risk of anxiety.
