The impact of electrosmog on sleep and concentration – what the research says and how to protect yourself

In the era of ubiquitous electronics, it's increasingly difficult to escape electrosmog. Many people wonder whether invisible waves emitted by phones, Wi-Fi, and electrical devices can affect our well-being. Does electromagnetic radiation disrupt sleep and impair concentration? Below, we explain in an accessible way what electrosmog is, what the latest research says, and how we can protect ourselves and our loved ones from excessive exposure.

What is electrosmog?

Electrosmog (electromagnetic smog) is a colloquial term for excess electromagnetic radiation in the environment, generated primarily by man-made devices. Simply put, it is "electrical pollution" of the environment caused by numerous sources of radio and microwave waves. The most common sources of electrosmog include:

• Mobile phones and base stations (telephone towers) – emit radio waves during calls and data transmission.

• Wi-Fi routers and wireless devices (e.g. modems, baby monitors, smartwatches) – transmit radio signals in the microwave band, creating a wireless network in the home.

• Bluetooth and smart home devices – continuous communication without cables (e.g. headphones, speakers, sensors) also contribute their share of radiation.

• High-voltage lines and energy infrastructure generate low-frequency electromagnetic fields.

• Household appliances – televisions, computers, microwave ovens, dryers, etc., emit electromagnetic fields during operation.

Electromagnetic fields also occur naturally in the environment (e.g., the Earth's magnetic field and cosmic radiation), but electrosmog refers primarily to artificially generated fields , the number of which has increased dramatically with technological advances. Although the term electrosmog is not an official scientific concept, it reflects concerns that excess such radiation may negatively impact health.

How does electromagnetic radiation affect the brain?

Our bodies and brains function based on electrical signals —neurons communicate with impulses that can be measured as brain waves (visible, for example, in an EEG). It's no wonder, then, that questions have arisen about whether external electromagnetic waves can disrupt these delicate processes.

Research suggests that EM fields can penetrate the body and trigger subtle responses in the nervous system . For example, a 2023 experiment demonstrated changes in brain electrical activity in individuals exposed to cell phone signals. A slight increase in alpha wave power was observed in the brain during radiation exposure (compared to sessions without radiation). Alpha waves are associated with a state of relaxation during wakefulness—their disruption suggests that cell phone radiation may actually affect brain function . Although such effects are subtle, they provide evidence that artificial electromagnetic fields affect the brain's bioelectrical activity .

Other scientific reports indicate that prolonged exposure to radio and microwave radiation can lead to stress in neural cells. Among other things, increased oxidative stress in neural tissue has been reported, potentially leading to accelerated cell wear and tear and impaired function. Oxidative stress in the brain has been linked to memory impairment and accelerated mental fatigue. Although the mechanisms are not fully understood, there are hypotheses that microwaves at frequencies used in telecommunications may also affect neurons through so-called non-thermal effects (i.e., those not related to tissue heating). Certain radio signal modulation frequencies are similar to the brain's operating frequencies, which raises the possibility that they may disrupt natural biological rhythms .

In short, electromagnetic radiation, although imperceptible to the senses, provides an additional stimulus to the nervous system . In some people, this may result in overload or dysregulation of certain brain functions, especially with long-term exposure.

Electrosmog and sleep quality

One of the most common areas of concern is the impact of electrosmog on sleep and nocturnal regeneration . Sleep is a state in which the brain shifts to altered wave activity (slower delta waves dominate in deep sleep). Could ubiquitous radio waves disrupt this process?

Some studies suggest that prolonged exposure to strong electromagnetic fields can impair sleep quality . People living near cell phone towers or sleeping next to active electronic devices are more likely to report difficulty falling asleep, insomnia , light sleep, and frequent waking during the night . Cell phone radiation, for example, can delay the onset of deep sleep, as the brain is stimulated by radio signals even during rest. There are also reports that electromagnetic waves can lower melatonin levels—a hormone that regulates our circadian rhythm—though the results of such studies are inconclusive. However, it is certain that people sensitive to electrosmog often experience relief in the form of better sleep after limiting their nighttime exposure (e.g., turning off Wi-Fi and placing their phone away from the bed).

On the other hand, some experiments don't confirm a direct, short-term effect of Wi-Fi on sleep . In controlled conditions, when subjects slept for one night next to a router that was turned on, there were no significant changes in sleep parameters compared to a night without the router—at least statistically speaking. It's important to note, however, that the lack of a short-term effect doesn't rule out long-term effects . It's a bit like noise: a single noise might not wake us up, but the constant noise outside night after night affects our well-being over time.

In summary, excess electrosmog can impede healthy, deep sleep , especially in susceptible individuals. This manifests itself through insomnia, light sleep, or morning fatigue despite adequate sleep. Therefore, experts recommend limiting exposure at night whenever possible to give the body a chance to fully regenerate.

Electrosmog and concentration and memory

The second key aspect is whether living in a "cloud" of wireless signals translates into difficulty concentrating, learning, or remembering information . Many people working in offices filled with electronics or spending all day on their phones complain of mental fatigue and difficulty concentrating . Could electrosmog be to blame?

The list of possible symptoms of overexposure actually includes poor concentration, memory problems, distractibility , and general irritability. There may be several mechanisms involved. First, if radiation disrupts brainwaves (as described above), it makes it harder to maintain focus—the brain receives additional "noise" that it must filter. Second, chronic oxidative microstress in the nervous system can affect cognitive function , causing us to feel constantly mentally fatigued. Finally, there's an indirect aspect: the constant presence of the phone and the internet distracts us (although this is a psychological, not physical, effect).

What does scientific research say about this? A project by Swiss scientists from Swiss TPH provided interesting data. They observed several hundred teenagers using their cell phones for a year. The results were disturbing: teenagers who regularly held their smartphones to their heads experienced memory deterioration after 12 months compared to their peers. The more often the phone was held to the ear (especially on the right side of the head), the more pronounced the decline in memory retention. Researchers linked this to brain exposure to microwaves from phones . Although the study focused on adolescents, it suggests that constant exposure to cell phone signals can impair cognitive function . Other experiments (e.g., on mice) have also confirmed the link between phone radiation and memory impairment and hyperactivity—exposure in utero resulted in ADHD-like symptoms in young rodents.

In everyday life, many people describe so-called brain fog —a feeling of mental fog and difficulty thinking clearly—when exposed to strong electromagnetic fields for long periods (e.g., in large offices packed with electronics). While mainstream medicine doesn't recognize a single, definitive diagnosis, the term electromagnetic hypersensitivity (EMH) is becoming increasingly common. It describes a set of symptoms (from headaches and fatigue to difficulty concentrating) that some people experience when exposed to EM fields. Although causality can be difficult to prove, the reports of such patients suggest caution . For sensitive individuals, even simple Wi-Fi or working on a laptop for many hours can become a burden on the nervous system and mental acuity.

Children vs. adults – who is more at risk?

Electromagnetic radiation affects everyone, but children may be more sensitive to its effects . Their bodies are still developing: cells are dividing rapidly, the protective barrier (e.g., the skull) is thinner, and the nervous system is in the forming phase. In practice, this means that the waves penetrate deeper into a child's brain than in an adult's – a child's skull is thin and contains more fluid, which facilitates radiation penetration. Research by Dr. Om Gandhi and Dr. Devra Davis has shown that cell phone signals can reach deeper brain structures in children than in adults. In other words, a child's brain absorbs more radiation energy .

Moreover, the longer-term exposure perspective is crucial. Today's young generation is surrounded by electronics from a young age – if there are any negative effects of electrosmog, children face decades of life in this field . Potential damage can accumulate over time. For this reason, many institutions recommend the precautionary principle for children. For example , France has introduced a Wi-Fi ban in nurseries and preschools , and schools are restricting the use of wireless devices to reduce children's exposure to electromagnetic fields. Some countries also recommend that children under 12 use cell phones only when necessary (e.g., emergency calls) and avoid holding devices to their heads.

Of course, adults can also feel the effects of electrosmog , especially if they are exposed to intense radiation (e.g., working near strong transmitters or using their phones very frequently). However, adults have fully developed bodies and thicker skulls, so they absorb slightly less radiation. Nevertheless, even for us, common sense is recommended: talk on the phone using speakerphone or with headphones , don't carry your smartphone constantly on your body, and keep it away from your bed at night. These are simple measures that protect both adults and children.

Symptoms of excessive exposure to electrosmog

How can we tell if we're surrounded by too much electrosmog? There are a number of nonspecific symptoms often reported by people in environments heavily saturated with electronics. The most common include:

• Sleep problems: difficulty falling asleep, shallow sleep, frequent waking up and, as a result, morning tiredness despite a good night's sleep.

• Headaches and dizziness: dull headaches, a feeling of heaviness or throbbing in the temples, sometimes accompanied by dizziness, occurring without any other apparent cause.

• Chronic fatigue and lack of energy: a feeling of constant exhaustion, weakness, and daytime sleepiness, which may result from poor sleep or from the stress on the nervous system.

• Difficulty concentrating, irritability: difficulty sustaining attention, absent-mindedness, as well as increased irritability, nervous tension, or anxiety. The person may feel agitated for no apparent reason.

• Other general complaints: tinnitus, heart palpitations, skin rashes, muscle pain, and nausea are sometimes reported. In some people, these symptoms constitute electromagnetic hypersensitivity (EHS) .

Of course, the above symptoms are very common and can have dozens of other causes (stress, work overload, dehydration, etc.). Therefore, it's difficult to definitively determine whether electrosmog is the culprit. However, if we notice an improvement in our well-being after turning off electronic devices for a while (e.g., a weekend electronics detox in nature results in better sleep and mental clarity), this may be an indication that electromagnetic radiation has been negatively affecting the body . In such a situation, it's worth implementing preventative measures.

How to reduce radiation in everyday life?

The good news is that we can easily reduce our exposure to electrosmog in our own environment. Here are some practical tips to help reduce electromagnetic radiation levels at home and at work:

• Turn off your Wi-Fi at night: Your wireless router doesn't need to be on while you sleep. Turning it off at night will significantly reduce the levels of RF in your bedroom and throughout your home. As a result, your body will have a chance to enjoy a more restful night without additional stimulation.

• Move devices away from your sleep space: Don't keep your phone near your bed (it's best to leave it in another room or on airplane mode). Remove unnecessary electronics from your bedroom – shielding your bedroom can be as simple as moving the TV or unplugging the power strip next to your bed. The farther away emitting devices are from your body, the less impact they have on you.

• Use airplane mode: If you don't need to be constantly connected, switch your smartphone to airplane mode (it turns off GSM/Wi-Fi/Bluetooth transmitters). You can do this during meetings, focused work, and especially when traveling, when the signal is constantly fluctuating and your phone transmits at higher power while searching for a signal.

• Choose wired connections over wireless: Whenever possible, use wired internet (Ethernet) instead of Wi-Fi. The same applies to peripherals – wired mice and keyboards, for example, don't generate electromagnetic fields, unlike wireless versions. Wired internet is not only healthier (no emissions) but often more stable and faster.

• Limit close contact with your phone: Avoid carrying your cell phone next to your body all day. Keep it in your purse or backpack instead of your pocket. When making phone calls, use a headset or speakerphone – this allows you to keep the device at a distance from your head. This reduces the radiation dose reaching your brain .

• Take breaks from electronics: Try not to spend hours on your computer or smartphone. Get up periodically, step away from your devices, and get some fresh air. Give your eyes and brain a break from electromagnetic stimuli. Even a short break every hour reduces the accumulated stress. In the evening, implement a digital detox – spend the last hour before bed without screens and electronics, which will prepare your body for calm.

• Shielding and Neutralization: If you live near sources of strong electromagnetic fields (5G towers, power lines), consider additional measures. Special shielding paints for walls or window films can partially block the penetration of external radiation. Radiation neutralizers are also available—neutralizing devices that, according to manufacturers, absorb or harmonize electromagnetic waves. These can be placed next to a router, computer, or in a bedroom to mitigate the impact of continuous signals. Although the effectiveness of anti-radiation devices is debated , many people subjectively experience improvements thanks to them (better sleep, fewer headaches, etc.). It's worth choosing proven products and remembering that they are a complement, not an excuse, for unrestricted use of electronics.

The above actions constitute digital hygiene . They allow you to reap the benefits of technology while minimizing its potential side effects . The key is to use devices consciously – technologies are meant to serve us, but we control how much time we spend within their reach.

Natural methods to support the regeneration of the nervous system

In addition to reducing radiation itself, it's also worth strengthening your body to better cope with unavoidable exposure. Here are some natural ways to support your nervous system and recover after a day full of stimuli:

• Healthy lifestyle: A balanced diet rich in antioxidants (vegetables, fruits, nuts), adequate hydration and regular physical activity significantly help the body neutralize the effects of environmental stress Antioxidants in food can combat excess free radicals produced by factors such as radiation, and exercise improves circulation and oxygenation of the brain.

• Avoiding stress and calming down: High levels of mental stress lower our resistance to all external factors. Try to incorporate relaxation techniques into your daily routine – meditation, breathing exercises, yoga, or a walk in nature will help lower cortisol levels in the blood. A calmer, more balanced nervous system will better tolerate even electromagnetic stimuli.

• Sleep hygiene: Nothing regenerates the brain like solid, uninterrupted sleep. Maintain consistent bedtimes and wake-up times. Sleep in a dark and quiet environment, free from electronic devices (as mentioned earlier). Deep sleep is a time when the nervous system "repairs" itself—memories are consolidated and toxins are removed from the brain. If you live in an area with high RF radiation (e.g., a city center), consider sleeping in a more sheltered room or using a bed canopy made of RF-blocking fabric. Even small steps—like moving your bed away from a wall with electrical wires—can reduce exposure while sleeping.

• Contact with nature and "earthing": Spend time in nature, away from urban sources of electrosmog. Forest bathing , trips out of town, or even a weekend in the countryside allow the nervous system to rest from ubiquitous signals. Many people also recommend earthing —walking barefoot on grass or the beach—which is said to help discharge accumulated charges and restore electrical balance in the body. While it sounds unconventional, it certainly won't hurt and can even aid relaxation.

• Supplements and supportive herbs: Consider natural support for your nerves – magnesium is a mineral that promotes calm and proper functioning of the nervous system, as does vitamin B complex . Herbs like lemon balm, lavender, and ashwagandha (known for their adaptogenic properties, helping the body cope with stress) can be helpful. However, always consult your doctor before taking supplements, especially if you have health problems.

By using the above methods, you help your body regenerate and strengthen its natural defense mechanisms . This means that even if it's impossible to completely eliminate electrosmog from your environment, your body will be more resistant to its potential negative effects.

Summary

Electrosmog is an invisible element of the modern world that raises many questions. Although official regulatory bodies (e.g., WHO) maintain that radiation from everyday devices is safe when standards are followed, a growing number of scientists are pointing to the need for caution. Studies on the effects of electromagnetic fields on sleep, memory, and concentration are inconsistent – some show subtle but real biological effects , while others do not confirm any risks. In the face of uncertainty, the precautionary principle is recommended: limit exposure where possible and monitor your well-being.

With simple measures like the digital habits and healthy lifestyle described above, we can significantly reduce the potential risks associated with non-ionizing radiation without sacrificing the benefits of technology. Ultimately, it's about consciously using our devices – we decide when to go offline for the sake of our health.

Remember: your own well-being is paramount. If you sleep better and concentrate more easily after unplugging a few cords, it's worth making it a daily ritual. Small changes can translate into more restful sleep, a clearer mind, and a better quality of life .
