Using a laptop for a long time, the cervical spine is quietly protesting...Do you often feel like this: after working for a few hours, your neck starts to become stiff, your eyes become sore, and your back aches? Even if you stand up to rest or massage to relieve it, the pain will come back soon. This is not a problem with your body, but - your posture when using a laptop is wrong!The core problem is that the screen is too low, forcing you to lower your head to work, which will cause cervical and spinal strain over time.
