Computers In Bedrooms: Are They Safe?

There are many reasons why you might want to think twice before putting a computer in your bedroom. Computers emit electromagnetic radiation, which is harmful to the body, and the damage is at its worst when you are sitting close to the screen. The blue light from screens also inhibits the production of melatonin, the hormone that makes you feel drowsy, which can lead to insomnia and sleep deprivation. This can have a knock-on effect on your productivity and overall health. Computers also generate a lot of heat, and the fans can make your room dusty and noisy.

Computers emit electromagnetic radiation, which is harmful to the body

Computers emit electromagnetic radiation, which is potentially harmful to the body. They generate both low-frequency and radio-frequency electromagnetic radiation (EMR). EMR has been linked to several serious diseases, including damage to nerves, the immune system, and reproductive systems.

EMR is also linked to a condition known as Electromagnetic Hypersensitivity (EHS), which affects up to 3% of the population. Those with EHS experience symptoms such as concentration and memory disorders, skin prickling, itching, burning or flushing sensations, and muscle and joint pains when exposed to certain types of electromagnetic radiation.

However, it is important to note that modern flat computer screens (LCD or LED) generally produce far less EMR than older models, and maintaining a normal viewing distance from the screen can further reduce potential harm. Additionally, newer devices tend to emit lower levels of electromagnetic radiation.

To minimize exposure to electromagnetic radiation from computers, it is recommended to avoid close proximity to low-frequency radiation sources and to avoid using radio communication facilities. Keeping computers and similar equipment at a distance can effectively reduce exposure, as low-frequency radiation decreases rapidly with distance.

While electromagnetic radiation from computers can be a concern, taking simple precautions, such as maintaining a safe distance and following guidelines for usage, can help ensure a reduction in potential health risks.

Blue light from screens inhibits melatonin production, causing insomnia

Blue light is a wavelength of light often emitted by electronic devices and artificial lights. During the day, it can improve performance and attention, and boost alertness, reaction times, and mood. However, exposure to blue light at night has adverse effects on our sleep.

Blue light suppresses the production of melatonin, a hormone that makes us feel drowsy and is responsible for signalling to our body that it is time to sleep. Research has shown that blue light suppresses melatonin production for longer and shifts our circadian rhythm to a greater degree than green light. As a result, exposure to blue light before bed can disrupt our natural sleep cycles, making it difficult to fall and stay asleep.

The proliferation of electronics with screens and energy-efficient lighting means that we are increasingly exposed to blue light, especially after the sun has set. Most modern computers, TVs, smartphones, and tablets emit blue light, and the use of these devices before bedtime can contribute to or exacerbate sleep problems.

To improve sleep quality and duration, it is recommended to limit exposure to blue light in the evening by turning off electronic devices or using apps that filter out the blue light wavelength. Wearing blue-light-blocking glasses can also be an effective way to reduce blue light exposure and improve sleep.

Computers make your bedroom hot

Computers can make your bedroom hot. In fact, computers are surprisingly efficient heaters. Every single bit of electricity a computer uses is eventually released as heat. The more powerful your computer, the more heat it will produce.

A powerful gaming PC can increase the temperature of an average room by about 9°F (4°C) in 12 hours. In a test, a gaming PC and a $25 1500-watt space heater raised the temperature of a room from 70°F to 82°F (21°C to 27.5°C) in two hours.

The heat generated by computers comes from the resistance met as electricity flows through the wiring. Computers need fans to prevent them from overheating, and these fans blow hot air into the room. The heat output is strong and can cause your bedroom to heat up.

Older computers are more prone to overheating. Desktop computers have a giant fan at the rear that blows continuously while the machine is on. The fan needs to keep blowing to cool the processor, and this can make your bedroom hot and uncomfortable.

If your bedroom is not well-ventilated, you will feel the effects of the hot air coming from your computer. If you leave a space heater in a room with a closed door and shut windows, it will heat the room faster. The same is true for computers.

There are several ways to reduce the heat in your bedroom:

• Move your computer to a bigger, better-ventilated room.
• Use fans or air conditioning to improve air circulation.
• Make sure to shut down your computer when you're not using it.
• Limit the time you spend on the computer.
• Check for any unnecessary programs running in the background and close them.

Computer fans can make your bedroom dusty

Computers can impact your sleep and overall health. The blue light from screens is bad for your circadian rhythm, inhibiting the production of melatonin, the hormone responsible for drowsiness. The constant humming sound of the cooling fans may also delay your sleep.

To prevent dust from building up, you can try using a can of compressed air to blow the dust out or use a vacuum cleaner with the right attachment.

Computers can cause sleep deprivation and negatively impact your health

The presence of a computer in the bedroom can disrupt normal sleeping patterns in several ways. Firstly, the blue light emitted by screens inhibits the production of melatonin, the hormone responsible for making us feel drowsy. This disruption to our circadian rhythm can make it difficult to fall and stay asleep. Additionally, the constant notifications, sounds, and visual distractions from computers can interrupt sleep, and the humming noise from cooling fans can be particularly bothersome for light sleepers.

The convenience of having a computer in the bedroom can also lead to poor habits, such as staying up late to watch movies or play games. This can induce stress and reduce the amount of sleep you get, impacting your productivity and overall health. Furthermore, the clutter of computer equipment and the extra heat generated by the machine can make the bedroom uncomfortable and less conducive to sleep.

While it may not always be possible due to space constraints, it is advisable to keep computers out of the bedroom to promote a healthy sleep environment. If keeping a computer in the bedroom is the only option, it is recommended to shut it down when not in use, keep it away from the bed, and limit screen time before bed to improve sleep quality and protect your health.
