Working on the computer

This helps against mouse arm and cell phone neck
The back pain, the eyes burn, and the neck can hardly be moved: for many ending workdays or long game sessions, especially on a smartphone or notebook, but also on the big PC. Small tricks create the remedy and fit well into everyday life. Work at the computer is at first sight less difficult than on the construction site. However, long sitting and stiffness on the screen mean heavy back and eyes. And not only on the stationary computer but also on the road to smartphones and notebooks. In the meantime, almost everything that a large PC can do has become a mobile office for many - with negative health consequences. "Many people are looking down deeply at the use of their smartphones - and this leads to an overstretching of the throat muscles," says President of the Association of Operators, and speaks of the "mobile phone neck". The neck and back complaints can only be avoided under certain conditions when one or the other e-mail is read later. "Everyone should think about whether to use the PC for longer stories, which is certainly much better suited to these things". If it is absolutely the mobile phone, the user should hold the device in different positions and also times high in front of the face. This keeps the neck as upright as possible.

Ergonomic seating
But even a desktop PC does not automatically provide less discomfort. In order to be spared from back pain, users attach great importance to an ergonomic sitting position. "The table height should have elbow height, that is, the underarms should lie loosely on the table," recommends the chairman of the association for physiotherapy. If the workstation is used by several people, the computer monitor must also be height-adjustable next to the table. This makes it easier to adapt to different body sizes. Unfortunately, however, not every model has a corresponding device. Especially all-in-one PCs, with the entire computer behind the display, are usually very inflexible. In general, the more options a monitor brings to tilt and rotate, the better. Sascha from the Federal Institute for Occupational Safety and Health (BAuA) advises against intensive work with notebooks - if at all, then with a matt display that makes the eyes less stressful than a reflective one. "Due to the fixed connection between monitor and keyboard, notebooks are basically not suitable for permanent use," explains the ergonomics expert. For the elderly, however, a laptop can be even better, says an expert from the Ophthalmologist's Office: "They often wear progressive lenses and good visual acuity in close-up areas is only achieved when looking through the lower part of the glasses." With a notebook, the user has to look more downward, which is much easier and more ergonomic. The physiotherapist says: "The height, the seat inclination, the backrest and, if possible, the armrest should be adjusted." The correct position is reached when the feet are firmly on the ground and the knees are slightly below the waist so that the thighs slightly fall forward. With an ergonomic seating, however, it is not done. "The whole system is important," says the expert. And this also requires sufficient movement - in the ideal case, the table can be adjusted so far that its owner can work in a standing position. In order to stay in motion, a few tricks can be easily integrated into everyday life. "You can, for example, make calls on the phone or stand the printer away," advises the expert.

Mouse arm syndrome
Small helpers are also available for the mouse and keyboard badly stressed hands. As a result of the typical use, a nerve, which runs relatively superficially at the border between the wrist and the hand root, warned: "This can lead to the typical mouse arm syndrome with slight sensory disturbances or even to slight paralysis." Hand rest prevents this. In order to spare the eyes, the orientation of the desk has to be considered. "Reflections and glare can be avoided by the light coming from the side" recommend the expert. Nevertheless, the constant stare on the screen can permanently cause problems, because the protective tear film is only inadequately distributed. "This can lead to emotions, conjunctivitis, and inflammation," warns expert. So that it does not come so far while working or playing occasionally the view through the room. "The tear production is also promoted by fresh air," the ophthalmologist continues. "If possible, you should go for it a few minutes before the door."
