When you’re using it with a laptop, a laptop lap desk can provide insulating protection to your legs from the heat emanating from the laptop’s processors, while also helping to keep the computer’s fans unblocked, a good thing since building up heat can cause a slowdown, and can also shorten battery life. A lap tray can also facilitate. Displays / Desktops Motherboards / Components Networking / IoT / Servers. ASUS Download Center Download the latest drivers, software, firmware and user manuals.

Computers have offered us many conveniences. But, there are hidden dangers of their use that adversely affect our health in many ways.

Computer and laptop radiation effects on your health are a topic, which is under debate, and two schools of thought prevail.

Some feel that the computer screen radiation levels emitted are too low to present any threat or health risks to the human body and the odds are that no one will suffer any electromagnetic radiation (EMR) from the computer screen.

There are others who feel that there is a definite danger and a health risk from computer radiation exposure and that the computer companies are trying to bury the issue.

Research does have its good points. But, many a research has been proved to be wrong and subsequently its findings have been reversed.

If that is so, then using computer radiation protection products such as a radiation shield or filter and protection glasses will help to eliminate the risk of computer radiation dangers.

Modern computer screens emit both low-frequency and radio-frequency EMR. Both these have the potential to cause cancer. Even the World Health Organization endorses this fact.

Should you work on the computer during pregnancy?

Is it okay to use a computer screen during pregnancy? Again two thoughts prevail — Yes and No. It will be prudent to err on the side of caution and give safety a priority.

You could use the protective gear that is mentioned below. In pregnancy, eliminating the computer radiation harmful effects become essential because the computer screen health risks endanger not only you but also your baby.

Even keeping a laptop or a tablet on your tummy is not advised because the heat emitted from the laptop screen can harm your baby.

Computer radiation effects on health

When we sit for hours in front of the computer for days on end, we are exposed to the danger of radiation emitting from the computer monitor screen.

This computer radiation exposure does have harmful effects on our health and body. It produces certain symptoms and ill effects, which are seen on our eyes, the skin, the brain

Effects on skin

HEV light (High energy visible light) also referred to as blue light, is a high-frequency high energy light emitted by your smartphone, tablet, and computer screen.

The modern-day devices do not emit UV rays that were emitted by CRT screens previously used for monitor screens and televisions. The levels, though low, did cause skin damage over time.

According to dermascope.com, HEV light penetrates up to the hypodermis of the skin potentially causing more damage than ultraviolet rays.

HEV light exposure can lead to inflammation, delayed healing, inhibition of melanogenesis, skin dryness, dry wrinkled, and sagging skin.

Effects on eyes

“Computer vision syndrome” is the name given to the group of eye and vision effects caused by working on the computer. The most common effects are eyestrain, blurred vision, irritation, and dry eyes.

This study conducted by the National Institute of Healthrats suggests that computer monitor radiation leads to oxidative stress in the corneal and lens tissues.

Effects on the brain

Prolonged exposure to radiofrequency waves emitted from computer screens, laptops, and such devices is harmful to your body cells.

Computer effects on the brain include forgetfulness, increased risk of brain fog, brain cancer, and brain tumor.

Effects on pregnancy

Laptop computer Electromagnetic Fields (EMFs), also known as Electromagnetic Radiation (EMR), cause harm to the body.

Pregnant women and the unborn fetuses are particularly at a high risk of adverse effects from the EMFs.

Studies indicate that in pregnancy, the high level of nonionizing radiation has been associated with birth defects, genetic damage, and spontaneous abortion. This has not been scientifically proven, though.

Other side effects

Other side effects of prolonged sessions of laptop and computer use include a feeling of headaches, sleep deprivation, sickness, nausea, dizziness, and sweating.

How much radiation does the computer monitor screen emit?

First, understand that radiation is an umbrella term for traveling electromagnetic waves. It consists of infrared, visible light, and everything else on the electromagnetic spectrum.

Ionizing radiation is dangerous because it can damage human tissues.

According to the Massachusetts Institute of Technology, ionizing radiation x-rays are produced in the monitor’s cathode ray tube (CRT) when electrons flow towards the monitor screen and they are now designed in such a fashion that the levels of X-ray emission do not exceed the prescribed safety.

The intensity of the ultraviolet radiation (UV) emitted from the computer monitors is lower than that from the fluorescent lights and much lower than that emitted from the sun.

The U.S. FDA issued a code that forbids computer manufacturers from making television/computer screens that emit more than 5 milliroentgens per hour at a distance of 5 centimeters.

Computer radiation protection products and tips

• Use your laptop in battery mode. This reduces EMF emissions by 60-75%.
• Do not place the laptop on your lap. Place it on the desk.
• Connect to the internet using an ethernet cable. Avoid connecting through the Wifi.
• Take frequent breaks. Ideally, take a 20-second break every 20 minutes and look at an object 20 feet away.
• Drink plenty of water and have a healthy diet. Be sure you consume enough of vitamin A and C
• Exercise regularly
• Use a monitor with a flat-screen like a laptop or a LED, rather than the old monitors, which have the cathode ray tube (CRT) that emits radiation. You’ll be relatively safe from a LED screen at normal distances.
• Use a radiation filter and radiation protection glasses. These will eliminate more than 90% of the radiation.
• Check your eyes for any refraction error and get it corrected with glasses if necessary
• Keep an ionizer near the computer to neutralize the radiation.
• By law, the manufacturers have to follow certain parameters to ensure that the radiation levels are low. Most of the standard companies do observe these standards and so it will be prudent to be smart when buying.

Sales of laptops exceed desktops in the U.S.. That is really bad news for backs, and necks, and shoulder muscles. When you use a laptop on a desk like this, inevitably what has to happen is, because the sightline is so low and the screen is so low, the person has to sit forward in the chair; they’re not using the backrest, there’s no support, so that person is mainly supporting herself. The hands are above the elbows typically, or very often, and that tends to leave the shoulders up. It puts more of a strain on the wrist area, the fingers are often going higher than they need to.

If you’re going to use a laptop for any period of time, or use it regularly for a few hours a day, you really need to somehow separate the monitor and the keyboard, and there are lots of different options for doing that. Laptop stands are really quite low-tech and inexpensive, you can carry them around with you, and they’re lightweight. They raise your monitor up so that the sightline is much better, and having an external keyboard like this, particularly on a tray, puts that at the right height also. I’m feeling better already, because I’m able to lean back, my elbows are supported; altogether, I feel in a much more relaxed position.

So here’s one option for making it slightly more ergonomic. In this case my colleague Joe de Avila is using a completely separate monitor, completely separate keyboard, and just using his laptop as the computer brain. Here, we separated the tools, he has an external keyboard and mouse (they happen to be wireless) and a very large screen. The important thing is to get the monitor up to the height of your eyes, and the keyboard down even with your elbows; then, you’ll be much more comfortable.
