By keeping you cool where your body needs it and warm where you need it, CLOtherapy clothing means you can stay cool when the heat is on and warm when it"s cool. Where should you send your technical queries? Where should you send your licensing enquiries? What clothing could the patented "CLOtherapy design concept" be applied to? In time all clothing could be made this way.
How can CLOtherapy clothing help you gain weight? Why is there less bulky white fat in certain areas armpits, backbone, breastbone and groin? Less bulky white fat suggests these areas need less insulation - the "CLOtherapy design concept" provides less insulation in these areas. Why is cold good for muscle tone? Cold has been shown to improve muscle tone and nervous functioning - CLOtherapy clothing provides for cold stimulation.
Why is the CLOtherapy backbone panel so important? Like a thermometer, your spine gathers information about the temperature outside your body - the CLOtherapy backbone panel allows for increased temperature-sensitivity along your spinal thermometer. What are the likely benefits of keeping your spine cool? Why are certain areas more sweaty than others armpits, backbone, breastbone and groin?

Anat 1 pp, Thomas pp , As Brown Adipose Tissue BAT between the shoulder blades in mice switches off, mice become more sensitive to the cold, they get very fat and their appetite increases - As BAT switches back on their weight returns to normal. This long-awaited but major breakthrough in clarifying the massive role of brown fat BAT in preventing long-term obesity, follows pioneering British researchers Dr Nancy Rothwell and Professor Michael Stock's findings, published over 15 years ago in Nature issue 6 September , suggesting that many men and women likely possess significantly active brown fat especially in areas such as the back, breastbone and neck that can be switched on for some reason when they eat excess calories; I report now on a new way to help regulate brown fat - again from Britain - that of The science of CLOtherapy - improving the environmental temperature of the nervous system, and so your vitality, by redressing the fat thermostat; Adrenaline-REsearch A-RE have reclassified Brown Fat's first and foremost role as a STRESS ADAPTIVE TISSUE - vital to our health and well-being.
Government statistics show that one in eight people are grossly overweight and in view of the fact that healthy weight control takes time What's the healthiest way to be overweight while you shed that bulky fat?
You could try cutting out chocolate, biscuits and beer for the rest of your natural life. Or, you could change your clothing. New research suggests that properly designed clothes can have a profound effect on your metabolism, your weight, and your health. It might sound strange - but this new approach to vitality and weight control, called CLOtherapy training, is supported by an increasing body of international research Babies have brown fat, but until recently most doctors thought it disappeared as we grow older.
That idea, however, is changing. Dr Pirkko Huttunen, who is Vice-President of the International Society for Adaptive Medicine, studied indoor and outdoor workers in Northern Finland, where the climate is usually cool or cold. The office workers apparently had no brown fat but outdoor workers, such as lumberjacks, did.
Dr Huttunen believes the body adapts to cold by growing pockets of brown fat in areas of exposed skin which allow the body to rev up its central heating, burning blood fats and sugars instead of coal. Back in the stone age, brown fat was likely essential, says Dr Huttunen.
How else could we keep warm through the long glacial winters? But nowadays office jobs, central heating and warm clothing ensure that our bodies are seldom exposed enough, to stimulate the cold-associated growth of brown fat; so the brown fat we have as babies usually fades away. This explains why few other scientists have found brown fat in adults. Basically, we need to exercise to train our brown fat. If these nerves are exposed to the stimulating stress of cool temperatures, they send a message to the hypothalamus in the brain, telling it that it's okay to raise the thermostat.
The brain then allows the skin's brown fat areas to start shedding excess fuel and, the heat that this activity generates, may help raise the body temperature back up to normal. Professor George Bray of the Pennington Biomedical Research Center, Louisiana, USA, found that certain stimuli cause the body to start heating up, and his team are convinced that brown fat is involved.
Professor Bray can explain that too: One reason for obesity may be that certain people are not able to burn off calories as heat, and store them instead as white fat. This could be why older people tend to put on weight, because with aging brown fat becomes less efficient, and less able to burn unwanted calories.
But is it possible to develop brown fat without going to Finland to work as a lumberjack? The answer is almost certainly yes. New work, by Stéphane Krief, Daniel Ricquier, and colleagues, at the University of Paris has shown that in both adults and children, dormant brown fat cells can be turned into active brown ones whenever apparently the nervous system directs the shedding of excess fats; Increasing A Fat breakdown and B Fat excretion from the intestines.
Other studies, around the world, suggest that to increase the efficiency of your active brown fat: Exercise regularly in cool temperatures to train your aerobic ability to generate your own warmth by exercising, put the thermal underwear back in cold storage, and save on those fuel bills by turning down the central heating American Scientists, and writers, Durk Pearson and Sandy Shaw agree with the importance of cooling, but emphasise the importance of keeping active.
Exercise usually causes a rise in body temperature, which can suppress brown fat formation; but exercise which is not accompanied by rise in body temperature, such as swimming in cool or lukewarm water, increases brown fat in experimental animals, and boosts their metabolism. Regular cold baths are an acquired taste, and take some mastering even if they can stimulate brown fat, so is there an alternative? This important research proved that a slight cooling of the body may trigger the brown fat, and start it burning calories which can help to maintain body temperature.
At Trinity College, Dublin, Dr Juliet Heaton, discovered brown fat in all age groups from babies to adults aged 80; most importantly her work suggests that the type of brown fat found at the skin's surface, for example between the shoulder blades, is most sensitive to the brown fat activating effects of cool temperatures. In separate studies on metabolic responses of young men and women to cold stress, researchers Andrews and Jackson at Trinity College, Dublin discovered that the more obese we become especially women , the more our nervous system reduces heat output in response to stress.
This effect could compound the problem of weight loss in obesity. So is there a comfortable way of exercising an increased metabolic shedding response to stress if you're overweight and reducing the stress response if you're underweight? Plant nutrition includes the nutrients necessary for the growth, maintenance, and reproduction of individual plants; the mechanisms by which plants acquire such nutrients; and the structural, physiological, and biochemical roles those nutrients play in metabolism.
Living organisms can be categorized by the way in which the functions of food are carried out in their bodies. Thus, organisms such as green plants and some bacteria that need only inorganic compounds for growth can be called autotrophic organisms; and organisms, including all animals , fungi , and most bacteria, that require both inorganic and organic compounds for growth are called heterotrophic.
Other classifications have been used to include various other nutritional patterns. In one scheme, organisms are classified according to the energy source they utilize.
Phototrophic, or photosynthetic , organisms trap light energy and convert it to chemical energy , whereas chemoautotrophic , or chemosynthetic, organisms utilize inorganic or organic compounds to supply their energy requirements. If the electron -donor materials utilized to form reduced coenzymes consist of inorganic compounds, the organism is said to be lithotrophic ; if organic, the organism is organotrophic.
Combinations of these patterns may also be used to describe organisms. Higher plants, for example, are photolithotrophic; i. Certain photosynthetic bacteria that cannot utilize water as the electron donor and require organic compounds for this purpose are called photoorganotrophs.
Animals, according to this classification, are chemoorganotrophs; i. Despite wide variations in the nature of the external energy source utilized by various organisms, all organisms form from their external energy source an immediate source of energy, the chemical compound adenosine triphosphate ATP.
This energy-rich compound is common to all cells. Through the breaking of its high-energy phosphate bonds and thus by its conversion to a less energy-rich compound, adenosine diphosphate ADP , ATP provides the energy for the chemical and mechanical work required by an organism. The energy requirements of organisms can be measured in either joules or calories. We welcome suggested improvements to any of our articles.
