8 Health Problems You May Encounter With Your Laptop and How to Solve Them

 Laptops due to their lightness, mobility¹ and new facilities like WiFi, which allow people to use internet almost everywhere, have become an integral part of many people's life especially youngsters. Everyone will agree that there is no harm in having a laptop. But the problem is that people strain their eyes in very unhealthy and unsuitable postures³ for long hours. Youngsters use most of their leisure time on their laptops watching movies, surfing or even working.

Posture² is not the only problem with the use of laptops. High performance laptops, which are more and more available on the market, seduce⁴ everyone. Nevertheless, they generate much more heat than the usual desktop⁵ computer.

   1. Laptops and children

      Problem: The BBC is reporting that laptop with WiFi antennas⁷ should not be placed near the laps of children until the research on health problems caused by them become clearer. Such antennas are similar to mobile phone antennas, except that they are less powerful. Prof Challis pointed⁸ that children are more sensitive to UV than an adult. He noted⁹ that since children are not allowed to use mobile phones for their own safety, the same applies for laptops.

      Solution: Children can use desktop computers since the emissions¹⁰ from the antenna⁶ will affect them less as they are situated¹¹ in the tower which is further from their lap.

   2. Laptops and infertility¹²

      Problem: It is known among researchers that a rise in temperature by 1 degree Celsius¹³ in the sac surrounding the testicles, known as the scrotum, leads to a decrease of synthesis of normal healthy sperm¹⁴ by 40%. A study carried out by a group of researchers from the State University of New York at Stony¹⁵ Brook¹⁶ revealed that for a person who uses his laptop on the laps, the median temperature rise in the scrotum is around 2.6 to 2.8 degrees Celsius.

      Further research is needed to find if there is a correlation¹⁷ between infertility and using a laptop on the lap. But there is surely a decrease in the number of normal sperm cells or sperm count.

      Solution: Place the laptop on a surface instead of your lap when you are using it. Or you can buy stands for laptop.

   3. Laptops and burns

      Problem: The heat from the laptop on the lap also causes skin and groin burns. To protect themselves from burns, certain people place a pillow between their lap and laptop. This can turn out to be more dangerous as the air vent¹⁸ of the laptop are blocked. The fans work faster but only to circulate a heated air that cannot escape. There are high risks that your laptop plastic back cover melts and causes more serious burns.

      Solution: Firms are designing very comfortable and safe lap rests for your laptops. They can be searched through the internet.

   4. Laptops and wrist pains

      Problem: Excessive typing causes the wrist to press against the edge of the laptop's border which is sharp in certain models. This causes compression of nerves and blood vessels¹⁹ leading to wrist and finger pains due to insufficient²⁰ circulation of blood to the extremities²¹ of the hand.

      Solution: Simple flexions and extensions of the wrist and fingers must be done frequently to promote blood circulation.

   5. Laptops associated to shoulder and neck pains

      Problem: Laptop keyboards lack inclinations²² and proper hand rests. The elbow remains²³ suspended in the air, thus causing contraction²⁴ on the muscles of the shoulders and that of the neck. Prolonged use leads to shoulder and neck pains.

      Solution: The best solution to this problem is getting back to the ancient more ergonomic external keyboard connected to the laptop.

   6. Problem: Often the height of the screen is not ergonomic. The muscles of the back and the neck are used to have a better view of the screen display.

      Solution: The laptop can be placed on a support which permits us to see the whole content of the screen extend and stretch the neck muscles.

   7. Laptops and the eyes

      Problem: The eyes need rests and the lenses inside them have to relax after stretching. When using laptops or computers in general, the muscles that control the lenses remain in a static position depending on the number of hours you stare at the screen.

      Solution: To protect the eyes from strains, frequent poses are recommended. It is advisable to watch distant objects so as to allow the muscles to relax.

   8. Problem: The brightness of the screen is also important. Too much brightness or light from another source reflecting on the screen into your eyes can be harmful to the retina. The retina is a collection of light sensitive cells that collects information and sends them to the brain to be processed into vision.

      Solution: To avoid this, choose a suitable brightness as well as switching on the lights to dampen the amount of light from the laptop screen.

Laptops in no case will harm us if used correctly. We just need to control the amount of hours we spend in front of it and respect the body postures and constraints²⁵.
