Why the neck?

Leaning forward

"You might lean forward throughout the day, whether that's toward a computer monitor that's hard to see or toward another person during a conversation. If you extend your neck each time, that can strain the muscles and cause pain."

Getting stressed

"We carry a lot of stress in our necks. We raise our shoulders and tense our muscles,. If you have any underlying neck problems, it irritates them," Evangelista says.

Electronic screens

"We all spend a lot of time looking at electronic devices. The trouble is that your head is heavy; angling it up or down for a long time leads to muscle strain and pain."
