The original PEMF devices consisted of a Helmholtz coil which generated a magnetic field. The patient's body was placed inside the magnetic field to deliver treatment. Today, the majority of PEMF wellness devices resemble a typical yoga mat in dimensions but are slightly thicker to house several flat spiral coils to produce an even electromagnetic
The biological mechanism that regulates the relationship between the thermal dose and the healing process of soft tissues with low or high water content or with low or high blood perfusion is still under study. Microwave diathermy treatment at 434 and 915 MHz can be effective in the short-term management of musculo-skeletal injuries.
Depression was associated with diabetes in a 2010 longitudinal study of 4,263 individuals with type 2 diabetes, followed from 2005 to 2007. They were found to have a statistically significant association with depression and a high risk of micro and macro-vascular events.
Microwave thermotherapy is a type of treatment in which body tissue is heated by microwave irradiation to damage and kill cancer cells or to make cancer cells more sensitive to the effects of radiation and certain anticancer drugs.
The bands are still widely used for these purposes. For many people, the most commonly encountered ISM device is the home microwave oven operating at 2.45 GHz which uses microwaves to cook food. Industrial heating is another big application area; such as induction heating, microwave heat treating, plastic softening, and plastic welding processes.
The presence of the sign in the Appleton–Hartree equation gives two separate solutions for the refractive index. [6] For propagation perpendicular to the magnetic field, i.e., , the '+' sign represents the "ordinary mode," and the '−' sign represents the "extraordinary mode."
The depth of penetration depends on the frequency of the microwaves and the tissue type. The Active Denial System ("pain ray") is a less-lethal directed energy weapon that employs a microwave beam at 95 GHz; a two-second burst of the 95 GHz focused beam heats the skin to a temperature of 130 °F (54 °C) at a depth of 1/64th of an inch (0.4 mm) and is claimed to cause skin pain without lasting ...
Depression may be related to abnormalities in the circadian rhythm, [22] or biological clock. A well synchronized circadian rhythm is critical for maintaining optimal health . Adverse changes and alterations in the circadian rhythm have been associated with various neurological disorders and mood disorders including depression.
