Final answer:
To reduce overall stress levels, Liu should address any neglected physical needs such as exercise, nutrition, and sleep. Avoiding negative coping strategies like focusing on negative memories and avoiding excessive busyness is also advised.
Step-by-step explanation:
Liu, who has been stressed at work, would benefit most from addressing any physical needs that may have been ignored. This approach is a form of stress reduction techniques which includes ensuring adequate exercise, proper nutrition, and sufficient sleep, all of which can help the body handle stresses better. Techniques like meditation and relaxation or biofeedback could also be beneficial.
It's important to note that focusing on negative memories or keeping oneself overwhelmingly busy are not effective means of reducing stress. On the contrary, they could potentially exacerbate it. Additionally, taking multiple rapid and shallow breaths is not advised; instead, deep breathing techniques are a commonly recommended practice for calming oneself down during periods of stress.
