Problems faced during lock-down
As we all know that from 2020 all of us are fighting with corona epidemic, Because of this, our school and college have all been closed at home. Those who are working, they also have to work from home during the time of lock down. People have to sit in front of computer and laptop throughout the day.
Student whose online classes are going on, the also have to sit in front of the laptop throughout the day, due to this reason neck and back pain is being seen more in people.
Today we will talk about what is the right position while using laptop.
The problem with laptops: ergonomics
The design of a laptop (with the screen attached to the keyboard) forces users into a trade-off between poor neck/head posture and poor hand/wrist posture.
When the screen is at the right height to maintain good neck/head posture, the keyboard is too high which forces the user into bad hand/wrist posture.
When the keyboard is at the right height to maintain good hand/wrist posture, the screen is too low which forces the user into bad neck/head posture.
In the early days of personal computing desktop devices integrated the screen and keyboard into a single unit, and this resulted in widespread complaints of musculoskeletal discomfort. By the late 1970’s a number of ergonomics design guidelines were written and all called for the separation of screen and keyboard. The reason is simple – with a fixed design, if the keyboard is in an optimal position for the user, the screen isn’t and if the screen is optimal the keyboard isn’t consequently, laptops are excluded from current ergonomic design requirements because none of the designs satisfy this basic need.”
Since laptops aren’t going away anytime soon, it’s important we learn how to minimize risk of musculoskeletal discomfort when we use them.
Laptop ergonomics tips for frequent use
We highly recommend using external devices if you’re going to use your laptop as your primary device. Using an external monitor, keyboard, and mouse will allow you to set up a workstation that meets ergonomic design guidelines for computer use.
Laptop ergonomics tips for occasional use
Use a chair that supports a comfortable upright or slightly reclined position
Position your laptop for the most neutral wrist posture you can achieve. If you have a large binder handy, place the wider edge at your knees so it creates an angle that keeps your wrist straight and maximizes the height of the screen.
Angle the laptop screen back so you can see it with the least amount of neck deviation as possible
Stand up, stretch, and move. Your body is designed to move, not to remain in a static posture for long periods of time.
