By manipulating skin cooling during treatment, RF can also be used for heating and reduction of fat. Currently, the most common uses of RF-based devices are to noninvasively manage and treat skin tightening of lax skin (including sagging jowls, abdomen, thighs, and arms), as well as wrinkle reduction, cellulite improvement, and body contouring.

Radio frequency (RF) is the oscillation rate of an alternating electric current or voltage or of a magnetic, electric or electromagnetic field or mechanical system in the frequency [1] range from around 20 kHz to around 300 GHz.
The antennas contained in mobile phones, including smartphones, emit radiofrequency (RF) radiation (non-ionizing "radio waves" such as microwaves); the parts of the head or body nearest to the antenna can absorb this energy and convert it to heat or to synchronised molecular vibrations (the term 'heat', properly applies only to disordered molecular motion).
Radiofrequency thermocoagulation is a thermal pain treatment procedure. For example, percutaneous intradiscal radiofrequency thermocoagulation (PIRFT) involves the placement of an electrode or catheter into the intervertebral disc and applying an alternating radiofrequency current.
Radiofrequency ablation (RFA), also called fulguration, [1] is a medical procedure in which part of the electrical conduction system of the heart, tumor, sensory nerves or a dysfunctional tissue is ablated using the heat generated from medium frequency alternating current (in the range of 350–500 kHz).
RF personal safety monitors were originally designed for RF Engineers working in environments where they could be exposed to high levels of RF energy or be working close to a RF source, for example working at the top of a telecommunication tower, or working on the rooftop of a building where transmitting antennas are present. Most international ...
The theory agrees well with experiments on pure substances, but not for complicated environments such as the human body. This theory makes the assumption that the autocorrelation function of the microscopic fluctuations causing the relaxation is proportional to e − t / τ c {\displaystyle e^{-t/\tau _{c}}} , where τ c {\displaystyle \tau _{c ...
The cost of the brain using too much glucose is muscle loss. If the brain and muscles relied entirely on glucose, the body would lose 50% of its nitrogen content in 8–10 days. [13] After prolonged fasting, [clarification needed] the body begins to degrade its own skeletal muscle. To keep the brain functioning, gluconeogenesis continues to ...
