Many use it in the office, others at home and some do not take a minute off the monitor, at any time. But of course the excessive use of the computer also has possible negative health effects, and if these are neglected, they can obscure all the virtues that the PC offers nowadays, from the efficient multiplication of personal and work communications to the wonders of digital entertainment. The calculation is simple if its use is carried out in a healthier mode, then, your energy expenditure is lower. In simpler words, bad postures constantly force the joints and vice versa.
Back pain, neck, and muscular contractions, tendonitis, carpal tunnel syndrome or vibration of the hands and arms, also discomfort in the shoulders and legs. The starting point of different ailments, which usually manifest themselves after some years of working under the wrong conditions, since they affect the region of the spine, especially with the use of non-ergonomic chairs, very low desks and PC monitors below the height of the eyes.
Choosing a suitable seat can also help prevent trauma. Experts recommend using a chair that can adjust heights in swivel with five supported wheels. Special attention must be paid to the backrest, which should be high enough to cover the entire back. It is also beneficial to have a footrest.

The bad postures that people usually adopt have an impact on the sciatic nerve in the first instance, producing certain muscular tensions and pain that can be extended to the buttocks or displacement of the sacral–iliac joint that can end in waist pain.

Before the pains begin to be felt, it is also advisable that the person stand up and do gentle exercises during regular breaks, such as turning the torso and rotating the neck, these movements stimulate blood circulation and relax the vertebrae.
