A Short Statement on The Hum and Body Temperature by Dr Chris Barnes, Bangor Scientific and Educational Consultants E-MAIL email@example.com
The Hum and its history/geography are very briefly reviewed. There are anecdotal reports of people feeling very hot while experiencing the Hum. Mechanisms of stress and microwaves are considered as a reason for this internal heating. The latter would be accentuated if there were more pollutant nano-particles in the body. It ought to be possible to take a number of Hummers and non –Hummers and expose them to an r.f. source and instrument skin temperature changes. The results of such an experiment would either proof or disproof the above hypothesis. Complimentary evidence could be gained by skin and tissue biopsy.
The Hum is a hitherto unexplained low frequency noise phenomenon wherein people experience a quasi-periodic droning or pulsating noise usually at night or when it its quiet. Most famous examples in the USA/ Canada are the Taos, Kokomo and Zug Island hums and in the UK the Largs Hum. Hums are being heard increasingly around the world and have recently been shown by the present author to often have a magnetic as well as acoustic (acoustic- infrasonic) component(s). It is highly likely the perception of the magnetic Hum may be linked to the presence of pollutants in our environment, particularly in the form of geologic magnetite competing with biologic magnetite in our bodies .
Long term amateur Hum researcher John Dawes has made an observation based on interviewing several hundred people afflicted by the Hum that in some of this group their body temperature noticeably rises at night during Hum episodes rather than falls slightly as is the norm  http://www.johndawes.pwp.blueyonder.co.uk/factual.htm . Many of the respondents reported a feeling of heat in their skin when in bed and hearing the Hum.
Stress and body temperature
A first hypothesis would be to consider if the stress of being made to suffer by the Hum could affect temperature. Stress is known to reduce peripheral body temperature due to vasoconstriction and increase core temperature. Thus the surface should feel cooler in stress.
The converse is true of the Hum. Therefore it is unlikely that stress as a secondary effect of the Hum is responsible for elevated surface temperature as reported in the Hum.
Magnetite and microwaves
Magnetite is an excellent microwave absorber, indeed one of the most efficient about 13 times more efficient than water at 2.45 GHz, see Saimm and Kingman  and yet its presence in biology has been disregarded in calculating SAR for cell phones and the like. Maybe magnetite could also account for so called ‘non-thermal damage’ of EM fields to living system? 
In any event one expects biogenic magnetite to be laid down in places where it is really needed in the body such as the brain. On the other hand geologic magnetite due to PM2.5 pollution will, perhaps, be spread more evenly including the blood stream and skin.
Then if this is the case we have a hypothetical mechanism for Hummers feeling hot. Perhaps absorption of r.f. is occurring all the time into their skin but they notice it more at night when awakened by the Hum. The frequency giving rise to the skin warming might not necessarily be the same as those involved in the Hum but is just an ever present artefact.
Proposed controlled experiment.
It ought to be possible to take a number of Hummers and non –Hummers and expose them to an r.f. source and instrument skin temperature changes. The results of such an experiment would either proof or disproof the above hypothesis. Complimentary evidence could be gained by skin and tissue biopsy.
Other biological systems.
The assimilation of metal nanometre sized metal/metal oxide pollutant particles could have implications for the decline of other species both animal and vegetable and it is hoped to report on these soon and elsewhere. It is certainly relevant to tree decline, see Barnes .
