1. Take a break: Give yourself some short breaks to relax. You can stand up and walk, do stretching exercises, look at the distance or do something interesting to distract yourself. This helps to restore energy and concentration.

2. Drink water: It is very important to keep your body hydrated, because dehydration may lead to fatigue and low energy. Drinking a glass of water or some tea can help you refresh yourself and replenish the water your body needs.

3. Eat nutritious food: Choose healthy foods, such as fruits, nuts, whole grains and rich foods in protein. Avoid consuming too much caffeine and sugar, because they may lead to energy peaks and crashes.

4. Do short-term exercise: Doing some short-term physical exercise, such as brisk walking, deep breathing, stretching and squatting, can improve blood circulation, increase oxygen supply and raise energy level.

5. Relaxation skills: Use some relaxation skills to relieve stress, such as meditation, deep breathing, physical relaxation exercises or finding a quiet environment. These methods can promote relaxation and recovery and improve physical and mental state.

6. Adjust the working environment: Make sure your working environment is comfortable, quiet and ergonomic. Adjust the height and posture of the seat to make you feel comfortable and concentrate to the greatest extent.

7. Focus on important tasks: Give priority to important and urgent tasks and avoid distracting yourself in a low-energy state. Focus on key tasks, and you will feel more fulfilled and motivated after completion.
