Technology-based devices, like cell phones and wi-fi have become the norm in modern living and we can’t get away from them, but research has shown that they can have harmful effects on our bodies, especially our nervous systems.
Because of this, we should understand what Electromagnetic Frequencies (EMFs) are.
Electromagnetic fields (EMFs) are invisible areas of energy, often referred to as radiation. There are two main types:
- Low frequency (non-ionizing): from power lines, household electricity, Wi-Fi, cell phones, Bluetooth, appliances.
- High frequency (ionizing): from X-rays, CT scans, UV light — these are known to damage DNA and increase cancer risk.
EMFs have different effects on our health based on the type and duration of our exposure to them. They can result in the release of too many free radicals causing oxidative stress in our bodies, which can increase inflammation and accelerate aging.
EMFs affect the body’s metabolic functions and high levels of electromagnetic energy absorption can change our body’s electric current which disturbs the function of our tissues and organs. Strong EMFs (like near power lines or MRI machines) can cause nerve and muscle stimulation at very high levels.
The WHO’s International Agency for Research on Cancer (IARC) classifies radiofrequency EMFs (from mobile phones, etc.) as “possibly carcinogenic” (Group 2B). This means that there is some evidence of a link to cancer, particularly brain tumours, but this is still being researched.
This week we discussed some of the commonly reported symptoms which include:
Neurological and cognitive symptoms such as headaches or head pressure, difficulty concentrating, brain fog, dizziness or vertigo, memory problems, tingling or prickling sensations in skin
Sleep and mood related symptoms. EMFs, especially from screens and phones at night, may affect our melatonin production and circadian rhythm which can cause symptoms such as insomnia or poor-quality sleep, fatigue or daytime sleepiness. Anxiety, irritability, or mood changes can also be exacerbated by EMF exposure.
Next week we will discuss sensory symptoms, cardiovascular and autonomic nervous system symptoms as well as the impact of EMFs on fertility and reproduction. We will also discuss some practical tips to reduce our exposure.
