How computers effect your health?

By

Eyestrain

How computers effect your health?
The human eye structurally prefers to look at objects further than six meters away, so any work performed close-up puts extra demands on the eye muscles. While there is no evidence that eye fatigue is associated with damage to the eyesight, computer users may experience symptoms such as blurred vision, temporary inability to focus on faraway objects and headaches.
The following changes can be helpful:
  • Computer screen - Adjust the height of your screen so you're not tilting your head down and tensing your neck.
  • Lighting - Try adjusting the screen and the lights to keep glare to a minimum.
  • Rest breaks - Taking periodic breaks, during which you relax and gently stretch your neck muscles, can ease muscle strain. In addition, avoid any tendency to stare at the screen without blinking, since this can lead to dryness in the eyes.
  • Remembering to blink can help you avoid dry eyes

Headache

A computer screen is much like a television but you sit much closer to it. The light coming from the monitor can cause eyestrain if you stare at it for too long. This and also other reasons when working at a computer, including stress and poor posture can lead to a headache. Regular breaks can help reduce muscle strain and alleviate these problems.

Back pain

While working at the computer, back pain is one of the most common workplace problems. To increase comfort while working at the computer you should:
  • Practice 'dynamic sitting;' be flexible and move while sit, don’t just stay in one static posture
  • Adjust the backrest so you are sitting at a 90 degree angle. That means your legs and your body form an 'L' and your feet should be flat on the floor or on a footstool.
  • Adjust the lumbar support to fit your low back's natural inward curve
  • Adjust the height of the backrest to support the natural inward curvature of the lower back. Use a pillow or a towel if you have to.
  • Use your armrests. They support the weight of your arms and allow your neck and shoulder muscles to relax.

Carpal tunnel

Carpal tunnelCarpal tunnel syndrome is an injury caused by a pinched nerve in the wrist. The injury causes pain and numbness in the index and middle fingers and weakness of the thumb. To avoid that adjust the height of your chair so that your forearms are level with your keyboard and you don't have to flex your wrists to type. It's also important to take breaks and rest your hands and wrists.

Tips for a Happy Marriage

By
Marriage Boundaries You probably got married as friends, but then found yourselves running into difficulty because you each had your own way of living and doing. You came from one family, and your partner came from another family, and those families were different. Your job as a couple is to create some boundaries and rules that will guide you in your marriage. But if you’ve never created any rules before, and you or your partner don’t like rules and boundaries, it won’t be an easy task. Who is the Leader? You are equal partners making decisions in marriage. Responsibilities must be divided up. You need policies, procedures, and rules in order to work cooperatively as well as independently. You will enjoy working together as you know each other better and gain confidence in each other’s decision-making ability. Developing faith and trust takes many months.

Can Nightmares Cause Death? Spirit Possession? Mental Illness?

By
A lot of the research on nightmares suggests these events test the strength of one’s mind. If the mind is not strong, nightmares can take hold with greater force and the torment can extend beyond one’s dreams. Dr. Patrick McNamara of the Boston University School of Medicine looks at nightmares in a modern clinical context that also takes into account the history of dream phenomena in many cultures. He connects nightmares with a world of malevolent spirits. Spirit Possession Some people who experience frequent nightmares, both today and throughout history, also show signs in waking life of mental illness and even what may be seen as spirit possession. Dr. McNamara seems unabashed in speaking about spirit possession. “Nightmares very often involve supernatural characters that attack or target the dreamer in some way. I mean monsters, creatures, demons, spirits, unusual animals, and the like,” Dr. McNamara said in an interview with Boston University’s alumni publicat...
