Misophonia
Misophonia is characterized by strong negative emotions such as anger and anxiety in response to everyday sounds other people make. These sounds include humming, chewing, typing, and even breathing.
People with this disorder are not just getting annoyed at the sounds. They suffer breakdowns in relationships or even quitting their jobs.

Misophonia and brain particularities
Scientists do not fully understand misophonia but suspect it's caused by the way some people's brains process particular sounds and react to them.
Some studies found that the brains of people with misophonia showed hyperactivation of the salience network, a group of brain areas that direct our attention to important things in our surroundings. Trigger sounds send the salience network into an overdrive. Researchers found these brain areas are structurally more robust in people with misophonia.

Calming a misophonic brain
There's a lot of similarity between people who experience misophonia, but also a lot of diversity.
Therapists use a variety of techniques that is often based on the symptoms. Those who experience fear and anxiety may respond to exposure-based treatments. Those who experience anger can learn to manage their distress through distraction or relaxation techniques.

The electromagnetic (EM) spectrum
EM is the broad range of wavelengths. It is divided into seven regions and ordered in decreasing wavelength and increasing energy and frequency, namely radio waves, microwaves, infrared (IR), visible light, ultraviolet (UV), X-rays and gamma-rays.
Ultraviolet light falls is the range of the EM spectrum between visible light and X-rays.
UV is generally divided into three sub-bands
- UVA, or near UV (315-400 nanometers)
- UVB, or middle UV (280-315 nanometers)
- UVC, or far UV (180-280 nanometers)
Radiations with wavelengths from 10nm to 180nm are sometimes referred to as vacuum or extreme UV.

Yawning and brain activity
The urge to yawn increases when you try to stop yourself from doing so.
The tendency to yawn in return is linked to brain activity levels in a person's motor cortex. The more activity in the area, the more likely the person would be to yawn.
The history of refrigeration
Refrigeration is the action of creating cooling conditions by removing heat. It is used for preserving food by slowing bacteria growth.

Evaporative cooling
- 1720s. Scottish doctor William Cullen saw that evaporation had a cooling effect.
- 1748. Cullen demonstrated his ideas by evaporating ethyl ether in a vacuum.
- 1805. Oliver Evans designed a refrigeration machine that used vapor instead of liquid.
- 1820. English scientist Micahel Faraday used liquefied ammonia for cooling.
- 1835. Jacob Perkins, who worked with Evans, patented a vapor-compression cycle using liquid ammonia.
- 1842. John Gorrie, an American doctor, built a machine similar to Evans's design to artificially create ice and cool down patients with yellow fever.
- New and improved refrigeration ideas continued to be developed, including Albert Einstein's idea of an environmentally friendly refrigerator with no moving parts that did not rely on electricity.
- By 1920, refrigerators were considered essential in American homes.
How refrigerators work
Refrigerators today work by evaporating liquids.
The liquids are pushed through the refrigerator through tubes and begin to vaporize. As the liquids evaporate, they carry heat away with them as the gases travel to a coil outside the refrigerator. Here the heat is released. The gases return to a compressor, where they become liquid again, restarting the cycle.
