30 years ago, I and my class mates involved a research experiment with effect of Walkman’s headphone’s magnets. On the idea that magnetic forces pull the blood because blood contains iron. Sometimes it is claimed that the blood circulation is increased, last year I contacted my collegiates and asked if there was a follow up for the case founding and research individuals’ files. It has been a failure to participate research because of the University’s lack of interest on subject.

The connection between magnetism and organism has been known as long ago as the 1800s when Michael Faraday carried out his experiments, but the manufacturers of the electronics either don't realize, or don't want to publicize it. In action on the principle of attracting blood and increasing circulation in practice, the magnetic field has to penetrate tissue, which reduces its strength.
Hemocrit Test Hematocrit refers to the volume of red blood cells[contain iron] in your system. (This is also called packed cell volume – PCV). Your hematocrit count is the ratio of red cells to plasma (the liquid part of your blood). It is expressed as a percentage. As an example, if your hematocrit is 30 it means that 30% of the blood that was drawn is red cells; the remaining 70% is plasma. When you are on chemotherapy, your marrow’s ability to make new red cells is decreased, so your hematocrit will go down. Because there is less oxygen in your body, you will feel tired and have little energy. If your hematocrit drops below about 18 percent, you will probably need a red blood transfusion. http://www.teenslivingwithcancer.org/cancer-facts/treatment/all-about-tests/

If we held a magnet and they attracted blood, if we held them close to the brain for a long time [thinking these days teenagers’ habits], what is going to happen between blood circulation and O2 DISTRIBUTION at the center of the brain?

Levent, awesome.

May I ask, what about all the electromagnetic pollution all around us - could that also be related to chronic fatigue?

I believe, if electromagnetic pollution cumulative and steer in one direction it would cause a problem.

Using headphones at a sufficiently high volume level may cause temporary or permanent hearing impairment or deafness due to an effect called "masking." The headphone volume has to compete with the background noise, especially in excessively loud places such as subway stations, aircraft, and large crowds. Extended periods of the excessively loud volume may be damaging;[14][15] however, one hearing expert found that "fewer than 5% of users select volume levels and listen frequently enough to risk hearing loss."[16] Some manufacturers of portable music devices have attempted to introduce safety circuitry that limited output volume or warned the user when dangerous volume was being used, but the concept has been rejected by most of the buying public, which favors the personal choice of high volume. Koss introduced the "Safelite" line of cassette players in 1983 with such a warning light. The line was discontinued two years later for lack of interest.

The government of France has imposed[17] a limit on all music players sold in the country:[17] they must not be capable of producing more than 100dBA (the threshold of hearing damage during extended listening is 80dB, and the threshold of pain, or theoretically of immediate hearing loss, is 130dB).

Other risks arise from the reduced awareness of external sounds—some jurisdictions regulate the use of headphones while driving vehicles, usually limiting the use of earphones to a single ear. The complete isolation from outside noise can be a hazard in itself, as a user could miss the sound of a car horn and walk into traffic with fatal consequences. Losing situational awareness can also lead to theft, particularly in busy environments where bumping into another person would be ignored, e.g., metro stations.[citation needed]

Motorcycle and other power-sport riders benefit by wearing foam earplugs when legal to do so to avoid excessive road, engine, and wind noise, but their ability to hear music and intercom speech is enhanced when doing so. The ear can normally detect 1-billionth of an atmosphere of sound pressure level,[18] hence it is incredibly sensitive. At very high sound pressure levels, muscles in the ear tighten the tympanic membrane and this leads to a small change in the geometry of the ossicles and stirrup that results in lower transfer of force to the oval window of the inner ear (the acoustic reflex).[19] Since earplugs reduce the noise in the auditory canal, this protective mechanism is less likely to trigger, and full sensitivity of the ear is maintained. This technique allows excellent hearing of speech, music and most external sounds at sustainable levels without hearing damage.[citation needed]

Listening to music through headphones while exercising can be dangerous. Blood may be diverted from the ears to the limbs leaving the inner ear more vulnerable to damage from loud sound.[20] A Finnish study[21] recommended that exercisers should set their headphone volumes to half of their normal loudness and only use them for half an hour.
