Factors to be considered for your home workstation :
Height of the chair.
When sitting, the main part of the body weight is transferred to the seat. Some weight is also transferred to the floor, back rest, and armrests. Where the weight is transferred is the key to a good seat design. When the proper areas are not supported, sitting in a seat all day can put unwanted pressure on the back causing pain.
The lumbar (bottom five vertebrate in the lower spine) needs to be supported to decrease disc pressure. Providing both a seat back that inclines backwards, and has a lumbar support is critical to prevent excessive low back pressures.

Height of the keyboard. Make sure the hands are properly positioned at the keyboard. Manufacturers nowadays introduces ergonomic keyboard products to reduce wrists strain.
Keyboard and Typing Tips :
• Keyboard should be placed slightly lower than normal desk height to avoid strain in the forearm.
• If the keyboard is too large for your hands and fingers, try to reach the outlying keys by lifting your hand and arm from the shoulder rather than twisting your wrists or straining to reach those keys with your fingers.
• When typing, avoid resting your wrists on the edge of the work surface. Doing so can put additional pressure on those same tendons and nerves.
• Elbows should be in a 90-degree angle while hanging at the sides from the shoulders which should remain relaxed in a lowered position while typing.
• Use a padded wrist rest to reduce strain of the wrists. This will give support and to avoid the wrist hanging.
• When typing, keep hands relaxed,type gently, and do not pound the keys.
• Make it a habit to have frequent breaks to give your body a rest.
• If your hands and forearms hurt with your current keyboard, replace it at once preferably with an ergonomic keyboard.

Avoid eating in front of the table or computer especially cookies, bread, or other food with small particles which is hardly to clean when inserted inside the keyboard. Also avoid putting a drink near the equipment. Lastly, do not leave any food wrappers or unfinished food on top of the desk. Clean as you go.
