i used to do it often, mostly during lunchtime. but somebody sent me a message of its ill effects on our health. so if i could help it, i don't heat my food in the microwave anymore.

my mother has stents in her arteries of her heart, and the doctors at Duke hospital told me it was fine to use a microwave. Told me I would have to use it for hours at a time and her right beside of it for several days in a row, before it would hurt her.

Everyday at least 4-6 times. From reheating drinks and leftovers, to making popcorn at night for my snack.

U mean my wife ? oh..she uses quite often,,but not as a primary tool but as a secondary or supporting one...

![Microwave - Microwaves are electromagnetic waves with wavelengths longer than those of terahertz (THz) wavelengths, but relatively short for radio waves. Microwaves have wavelengths approximately in the range of 30 cm (frequency = 1 GHz) to 1 mm (300 GHz). However, the boundaries between far infrared light, terahertz radiation, microwaves, and ultra-high-frequency radio waves are fairly arbitrary and are used variously between different fields of study. The term microwave generally refers to "alternating current signals with frequencies between 300 MHz (3 x 108 Hz) and 300 GHz (3 x 1011 Hz)."[1] This range of wavelengths has led many to question the naming convention used for microwaves.
The existence of electromagnetic waves, of which microwaves are part of the frequency spectrum, was predicted by James Clerk Maxwell in 1864 from his Maxwell's equations. In 1888, Heinrich Hertz was the first to demonstrate the existence of electromagnetic waves by building an apparatus that produced and detected microwaves in the UHF region. The design necessarily used horse-and-buggy materials, including a horse trough, a wrought iron point spark, Leyden jars, and a length of zinc gutter whose parabolic cross-section worked as a reflection antenna.
The microwave range includes ultra-high frequency (UHF) (0.3-3 GHz), super high frequency (SHF) (3-30 GHz), and extremely high frequency (EHF) (30-300 GHz) signals.
Above 300 GHz, the absorption of electromagnetic radiation by Earth's atmosphere is so great that it is effectively opaque, until the atmosphere becomes transparent again in the so-called infrared and optical window frequency ranges.](http://img.mylot.com/350x350/141869.jpg "Microwave - Microwaves are electromagnetic waves with wavelengths longer than those of terahertz (THz) wavelengths, but relatively short for radio waves.

Sorry but i don't have microwave, im just a poor guy. lol

Everyday. We cant do without it now. Especially when our gas cylinders get over at home the micro is a real blessing
