I get sensitive to bright lights the more exhausted I get. I can't look at them.
Normal sunlight is like a mirror directly shining in my eyes, sometimes I squint in normal day light.
This may not be what you are describing?
Anyway, I was told (by a doctor, friend) phones and TVs admit some kind of non natural light, is it blue light. Watching them before bed can actually throw the body clock out?
< Maybe this his an more adverse effect on CFS/ME?
I admit looking at computer screen a while does make me feel odd when I stop.
Hope links are ok on here? I think this is fairly common knowledge now, not quackery.

I wonder (for me) if CFS/ME is something to do with the nervous system out of wack, so maybe sensory overload? I don't know I'm not a doctor.
For me, at times reading is hard, the words start to just look like letters and my memory struggles to make sense, like my memory does not understand or retain what I read.
Moving or flashing images also. Oh, and loud noises.
I wonder if maybe it is a similar response as to stress, not sure though I'm not a doctor.
I find wearing sun glasses sometimes helps, other times I need a dark quiet room.
Don't read on unless you are bored and have the energy...
Warning: Most my post are a load of rubbish. Might be a bit much for some people.
I'm quite analytical too, so might not be agreeable with everyone.
I am/was an engineer of sorts, so I'm kind of less open to some ideas.
I have to deal with facts, risks, liability, very dull. I don't really do grey areas.
So going away from light..
I find EMF hard to get my head round with my limited knowledge.
I know people will argue who wear those bracelets which claim to reduce pain etc..
As with acupuncture... studies found sticking those needles anywhere has a similar effect.
Yet, It probably does help some people, if the brain does have the power to heal?
You'd assume I'm anti alternative treatment, but I'm not at all.
Please don't get upset, just ignore anything you don't agree with because you'd be misjudging me.
I take supplements. I think massage is good.
I use a special light for vitamin D and morning body clock.
I read, the body uses electricity to send signals. > Your neurons carry messages in the form of
electrical signals called nerve impulses. ... Stimuli such as light, sound or pressure all excite your neurons,
Good so far.
Now the engineering bit (my perspective) many things around us could create magnetic fields, in engineering special cable is used to stop interference. So technically power sources could do this if you were that sensitive, power lines, speakers etc. maybe microwaves perhaps. Some things emit frequencies we can't hear too. I would be suspect about duration, range and power needed to feel in a detrimental way, if we were sensitive, I'd expect more people to ill who work with higher exposure..
The problem is, if we were
so sensitive to magnets, our brains or bodies were effected, I wonder if we'd be sick all the time. I appreciate some people with CFS/ME might be more sensitive than others.
"The Earth is a magnet that can interact with other magnets in this way, so the
north end of a
compass magnet is drawn to align with the Earth's magnetic field. Because the Earth's magnetic
North Pole attracts the "
north" ends of other magnets, it is technically the "South Pole" of our planet's magnetic field."
I don't understand the medical field, I have a hard job believing doctors some times (personal experiences).
There are three main reasons why people are concerned that cell phones (also known as “mobile” or “wireless” telephones)
might have the potential to cause certain health problems:
- Cell phones emit radio frequency energy (radio waves), a form of non-ionizing radiation, from their antennas. Tissues nearest to the antenna can absorb this energy.
- Over time, the number of cell phone calls per day, the length of each call, and the amount of time people use cell phones have increased. However, improvements in cell phone technology have resulted in devices that have lower power outputs than earlier models.
What is radiofrequency energy and how does it affect the body?
Radiofrequency energy is a form of
electromagnetic radiation.
Electromagnetic radiation can be categorized into two types: ionizing (e.g., x-rays, radon, and cosmic rays) and non-ionizing (e.g., radiofrequency and extremely low frequency, or power frequency). Electromagnetic radiation is defined according to its wavelength and frequency, which is the number of cycles of a wave that pass a reference point per second. Electromagnetic frequencies are described in units called hertz (Hz).
The energy of electromagnetic radiation is determined by its frequency;
ionizing radiationis high frequency, and therefore high energy, whereas non-ionizing radiation is low frequency, and therefore low energy.
The frequency of radio frequency electromagnetic radiation ranges from 30 kilohertz (30 kHz, or 30,000 Hz) to 300 gigahertz (300 GHz, or 300 billion Hz).
Electromagnetic fields in the radio frequency range are used for telecommunications applications, including cell phones, televisions, and radio transmissions. The human body absorbs energy from devices that emit radio frequency electromagnetic radiation. The dose of the absorbed energy is estimated using a measure called the specific absorption rate (SAR), which is expressed in watts per kilogram of body weight.
Exposure to ionizing radiation, such as from x-rays, is known to increase the risk of cancer. However, although
many studies have examined the potential health effects of non-ionizing radiation from radar, microwave ovens, cell phones, and other sources, there is currently no consistent evidence that non-ionizing radiation increases cancer risk (
1).
The
only consistently recognized biological effect of radiofrequency energy is heating. The ability of microwave ovens to heat food is one example of this effect of radio frequency energy. Radio frequency
exposure from cell phone use does cause heating to the area of the body where a cell phone or other device is held (ear, head, etc.). However, it is not sufficient to measurably increase body temperature, and there
are no other clearly established effects on the body from radio frequency energy.
As Gondwanaland mentioned....
It has been suggested that radiofrequency energy might affect glucose metabolism, but two small studies that examined brain glucose metabolism after use of a cell phone showed inconsistent results. Whereas one study showed increased glucose metabolism in the region of the brain close to the antenna compared with tissues on the opposite side of the brain (
2), the other study (
3) found reduced glucose metabolism on the side of the brain where the phone was used.
Another study investigated whether exposure to the radio frequency energy from cell phones affects the flow of blood in the brain and found no evidence of such an effect (
4).
The authors of these studies noted that the results are preliminary and that possible health outcomes from changes in glucose metabolism are still unknown.
Such inconsistent findings are not uncommon in experimental studies of the biological effects of radio frequency electromagnetic radiation (
5). Some contributing factors include assumptions used to estimate doses, failure to consider temperature effects, and lack of blinding of investigators to exposure status.
How is radiofrequency energy exposure measured in epidemiologic studies?
Epidemiologic studies use information from several sources, including questionnaires and data from cell phone service providers. Direct measurements are not yet possible outside of a laboratory setting. Estimates take into account the following:
- How “regularly” study participants use cell phones (the number of calls per week or month)
- The age and the year when study participants first used a cell phone and the age and the year of last use (allows calculation of the duration of use and time since the start of use)
- The average number of cell phone calls per day, week, or month (frequency)
- The average length of a typical cell phone call
- The total hours of lifetime use, calculated from the length of typical call times, the frequency of use, and the duration of use
What has research shown about the possible cancer-causing effects of radiofrequency energy?
Radio frequency energy, unlike
ionizing radiation,
does not cause DNA damage that can lead to cancer. Its only consistently observed biological effect in humans is tissue heating. In animal studies, it has not been found to cause cancer or to enhance the cancer-causing effects of known chemical carcinogens (
6–
8).
Researchers have carried out several types of
epidemiologic studies to investigate the possibility of a relationship between cell phone use and the risk of malignant (cancerous) brain tumors, such as
gliomas, as well as benign (noncancerous) tumors, such as
acousticneuromas (tumors in the cells of the nerve responsible for hearing), most
meningiomas(tumors in the meninges, membranes that cover and protect the brain and spinal cord), and parotid gland tumors (tumors in the salivary glands) (
9).
It is worth noting, recently they said booze can change DNA. Radio waves don't. Apparently!
I'm not worried and I worry about locking my front door, I check several times.
