1. Correct sitting posture: Office work often requires sitting in front of the computer for a long time. The correct sitting posture is very important, which can reduce the pain in the waist and neck. I suggest you choose an ergonomic chair and keep a good sitting posture.

2. Walk often: Sitting for a long time will not only affect your health, but also affect your work efficiency. I suggest you stand up and take a walk every hour to exercise.

3. Drink plenty of water: not drinking enough water will affect the body's metabolism and blood circulation. I suggest you prepare a glass of water in the office and drink it regularly.

4. Pay attention to diet: In the office, convenience foods and snacks often appear. Most of these foods contain a lot of fat, sugar and salt, which is not good for health. I suggest you prepare some healthy snacks and diets, such as fruits, vegetables, nuts, yogurt and so on.

As for the "healthy" snacks mentioned, I suggest you read their ingredient list carefully to know their calorie, sugar, fat and salt content. Although some snacks may be advertised as healthy food, they may still contain a lot of additives, sugar and fat. I suggest you choose brands you trust and try to reduce excessive consumption.
