Infrared Sauna
An infrared sauna uses infrared heaters to emit infrared light experienced as radiant heat which is absorbed by the surface of the skin. Infrared saunas are popular in alternative therapies, where they are claimed to help with a number of medical issues including autism, cancer, and COVID-19, but these claims are entirely pseudoscientific. Traditional saunas differ from infrared saunas in that they heat the body primarily by conduction and convection from the heated air and by radiation of the heated surfaces in the sauna room whereas infrared saunas primarily use just radiation. Infrared saunas are also used in Infrared Therapy and Waon Therapy; while there is a small amount of preliminary evidence that these therapies correlate with a number of benefits, including reduced blood pressure, increased heart rate and increased left ventricular function, there are several problems with linking this evidence to alleged health benefits.

Infrared Heater
An infrared heater or heat lamp is a heating appliance containing a high-temperature emitter that transfers energy to a cooler object through electromagnetic radiation. Depending on the temperature of the emitter, the wavelength of the peak of the infrared radiation ranges from to 1 mm. No contact or medium between the emitter and cool object is needed for the energy transfer. Infrared heaters can be operated in vacuum or atmosphere. One classification of infrared heaters is by the wavelength bands of infrared emission. * Short wave or near infrared for the range from to ; these emitters are also named "bright" because still some visible light is emitted; * Medium infrared for the range between and ; * Far infrared or dark emitters for everything above . History German-British astronomer William Herschel, Sir William Herschel is credited with the discovery of infrared in 1800. He made an instrument called a spectrometer to measure the magnitude of radiant power at differ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Harvey Kellogg
John Harvey Kellogg (February 26, 1852 – December 14, 1943) was an American businessman, Invention, inventor, physician, and advocate of the Progressive Era, Progressive Movement. He was the director of the Battle Creek Sanitarium in Battle Creek, Michigan, founded by members of the Seventh-day Adventist Church. It combined aspects of a European spa, a hydrotherapy institution, a hospital and high-class hotel. Kellogg treated the rich and famous, as well as the poor who could not afford other hospitals. According to ''Encyclopædia Britannica'', his "development of dry breakfast cereals was largely responsible for the creation of the Corn flakes, flaked-cereal industry, with the founding and the culmination of the global conglomeration brand of Kellogg's, Kellogg's (now Kellanova)." An early proponent of the germ theory of disease, Kellogg was well ahead of his time in relating Gut flora, intestinal flora and the presence of bacteria in the intestines to health and disease.

Obesity
Obesity is a medical condition, considered by multiple organizations to be a disease, in which excess Adipose tissue, body fat has accumulated to such an extent that it can potentially have negative effects on health. People are classified as obese when their body mass index (BMI)—a person's weight divided by the square of the person's height—is over ; the range is defined as overweight. Some East Asian countries use lower values to calculate obesity. Obesity is a major cause of disability and is Obesity-associated morbidity, correlated with various diseases and conditions, particularly cardiovascular diseases, type 2 diabetes, obstructive sleep apnea, certain types of cancer, and osteoarthritis. Obesity has individual, socioeconomic, and environmental causes. Some known causes are Western pattern diet, diet, low physical activity, automation, urbanization, quantitative trait locus, genetic susceptibility, medications, mental disorders, Economic policy, economic pol ...

Cholesterol Level
Cholesterol is the principal sterol of all higher animals, distributed in body tissues, especially the brain and spinal cord, and in animal fats and oils. Cholesterol is biosynthesized by all animal cells and is an essential structural and signaling component of animal cell membranes. In vertebrates, hepatic cells typically produce the greatest amounts. In the brain, astrocytes produce cholesterol and transport it to neurons. It is absent among prokaryotes (bacteria and archaea), although there are some exceptions, such as ''Mycoplasma'', which require cholesterol for growth. Cholesterol also serves as a precursor for the biosynthesis of steroid hormones, bile acid and vitamin D. Elevated levels of cholesterol in the blood, especially when bound to low-density lipoprotein (LDL, often referred to as "bad cholesterol"), may increase the risk of cardiovascular disease. François Poulletier de la Salle first identified cholesterol in solid form in gallstones in 1769. In 181 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chronic Pain
Chronic pain is pain that persists or recurs for longer than 3 months.https://icd.who.int/browse/2025-01/mms/en#1581976053 It is also known as gradual burning pain, electrical pain, throbbing pain, and nauseating pain. This type of pain is in contrast to acute pain, which is pain associated with a cause that can be relieved by treating the cause, and decreases or stops when the cause improves. Chronic pain can last for years. Persistent pain often serves no apparent useful purpose. The most common types of chronic pain are back pain, severe headache, migraine, and facial pain. Chronic pain can cause very severe psychological and physical effects that sometimes continue until the end of life. Analysis of the grey matter (damage to brain neurons), insomnia and sleep deprivation, metabolic problems, chronic stress, obesity, and heart attack are examples of physical disorders; and Depression (mood), depression, and neurocognitive disorders are examples of mental disorders.

Congestive Heart Failure
Heart failure (HF), also known as congestive heart failure (CHF), is a syndrome caused by an impairment in the heart's ability to fill with and pump blood. Although symptoms vary based on which side of the heart is affected, HF typically presents with shortness of breath, excessive fatigue, and bilateral leg swelling. The severity of the heart failure is mainly decided based on ejection fraction and also measured by the severity of symptoms. Other conditions that have symptoms similar to heart failure include obesity, kidney failure, liver disease, anemia, and thyroid disease. Common causes of heart failure include coronary artery disease, heart attack, high blood pressure, atrial fibrillation, valvular heart disease, excessive alcohol consumption, infection, and cardiomyopathy. These cause heart failure by altering the structure or the function of the heart or in some cases both. There are different types of heart failure: right-sided heart failure, which affect ...

Electromagnetic Spectrum
The electromagnetic spectrum is the full range of electromagnetic radiation, organized by frequency or wavelength. The spectrum is divided into separate bands, with different names for the electromagnetic waves within each band. From low to high frequency these are: radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays. The electromagnetic waves in each of these bands have different characteristics, such as how they are produced, how they interact with matter, and their practical applications. Radio waves, at the low-frequency end of the spectrum, have the lowest photon energy and the longest wavelengths—thousands of kilometers, or more. They can be emitted and received by antenna (radio), antennas, and pass through the atmosphere, foliage, and most building materials. Gamma rays, at the high-frequency end of the spectrum, have the highest photon energies and the shortest wavelengths—much smaller than an atomic nucleus. Gamma rays, X-rays, and ...

Far Infrared
Far infrared (FIR) or long wave refers to a specific range within the infrared spectrum of electromagnetic radiation. It encompasses radiation with wavelengths ranging from 15 μm ( micrometers) to 1 mm, which corresponds to a frequency range of approximately 20 THz to 300 GHz. This places far infrared radiation within the CIE IR-B and IR-C bands. The longer wavelengths of the FIR spectrum overlap with a range known as terahertz radiation. Different sources may use different boundaries to define the far infrared range. For instance, astronomers often define it as wavelengths between 25 μm and 350 μm. Infrared photons possess significantly lower energy than photons in the visible light spectrum, with tens to hundreds of times less energy. Applications Astronomy Objects within a temperature range of approximately 5 K to 340 K emit radiation in the far infrared range as a result of black-body radiation, in accordance with Wien's displac ...

Electromagnetic Far Infrared
In physics, electromagnetism is an interaction that occurs between particles with electric charge via electromagnetic fields. The electromagnetic force is one of the four fundamental forces of nature. It is the dominant force in the interactions of atoms and molecules. Electromagnetism can be thought of as a combination of electrostatics and magnetism, which are distinct but closely intertwined phenomena. Electromagnetic forces occur between any two charged particles. Electric forces cause an attraction between particles with opposite charges and repulsion between particles with the same charge, while magnetism is an interaction that occurs between charged particles in relative motion. These two forces are described in terms of electromagnetic fields. Macroscopic charged objects are described in terms of Coulomb's law for electricity and Ampère's force law for magnetism; the Lorentz force describes microscopic charged particles. The electromagnetic force is responsible for ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wilhelm II, German Emperor
Wilhelm II (Friedrich Wilhelm Viktor Albert; 27 January 18594 June 1941) was the last German Emperor and King of Prussia from 1888 until his abdication in 1918, which marked the end of the German Empire as well as the Hohenzollern dynasty's 300-year rule of Prussia. Born during the reign of his granduncle Frederick William IV of Prussia, Wilhelm was the son of Prince Frederick William and Victoria, Princess Royal. Through his mother, he was the eldest of the 42 grandchildren of Queen Victoria of the United Kingdom. In March 1888, Wilhelm's father, Frederick William, ascended the German and Prussian thrones as Frederick III. Frederick died just 99 days later, and his son succeeded him as Wilhelm II. In March 1890, the young Kaiser dismissed longtime Chancellor Otto von Bismarck and assumed direct control over his nation's policies, embarking on a bellicose "New Course" to cement Germany's status as a leading world power. Over the course of his reign, the German colonial ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Edward VII
Edward VII (Albert Edward; 9 November 1841 – 6 May 1910) was King of the United Kingdom and the British Dominions, and Emperor of India, from 22 January 1901 until Death and state funeral of Edward VII, his death in 1910. The second child and eldest son of Queen Victoria and Prince Albert of Saxe-Coburg and Gotha, Edward, nicknamed "Bertie", was related to royalty throughout Europe. He was Prince of Wales and heir apparent to the British throne for almost 60 years. During his mother's reign, he was largely excluded from political influence and came to personify the fashionable, leisured elite. He Wedding of Prince Albert Edward and Princess Alexandra, married Princess Alexandra of Denmark in 1863, and the couple had six children. As Prince of Wales, Edward travelled throughout Britain performing ceremonial public duties and represented Britain on visits abroad. His tours of North America in 1860 and of the Indian subcontinent in 1875 proved popular successes. Despite the ap ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
