Final answer:
Tech Neck is a new phenomenon caused by looking down at your cell phone. It leads to neck and upper back pain and stiffness due to poor posture. By holding the cell phone at eye level and doing exercises, you can prevent Tech Neck.
Step-by-step explanation:
The new phenomenon caused by looking down at your cell phone is called Tech Neck. Tech Neck refers to the neck and upper back pain and stiffness that can result from constantly looking down at a mobile device.
When you look down at your cell phone, you tend to hunch or slouch, which places strain on the neck and upper back muscles. Over time, this can lead to muscle imbalances, postural problems, and discomfort.
To prevent Tech Neck, try to hold your cell phone at eye level or use a tablet or book stand. You can also incorporate exercises and stretches to strengthen the neck and upper back muscles.
