Maintaining correct posture while sitting at a desk with a computer can help reduce the risk of injury and strain on the neck, back, and shoulders. Here are some tips to help you maintain good posture:

1. Keep your feet flat on the floor and sit all the way back in the chair with your back straight and shoulders relaxed.

2. Position your computer screen at eye level, so you do not have to tilt your head up or down.

3. Keep your mouse and keyboard within easy reach, so you do not have to reach or stretch while using them.

4. Take regular breaks to stretch and move your body. Set a timer to remind yourself to stand up and walk around every hour.

5. Consider using an ergonomic chair or a lumbar support pillow to help maintain proper spinal alignment.

6. Make sure your wrists are in a neutral position while typing, and use a wrist rest if necessary.

7. Avoid sitting in the same position for extended periods of time. Change your posture and take mini breaks to stretch your muscles.

Remember, it’s important to pay attention to your posture and make adjustments throughout the day to prevent strain and injury. Taking these steps can help ensure that you have a comfortable and productive workday.
