Why do we have a fever when we are sick?

The first thing a doctor or mother does when you feel unwell is to put a thermometer on you and take your temperature. This is how they try to find out if you have a "fever". The average body temperature of a person when he is healthy is 37 degrees Celsius. The disease causes the temperature to rise, and we call fever accompanied by chills a fever. Of course, not every disease causes a fever, but many do, and thus it is almost always a sign that something is wrong with your body.

In a hospital, a doctor or nurse usually takes the patient's temperature twice a day and enters it on a special chart showing fluctuations in body temperature. By looking at this chart, the doctor can tell quite accurately what disease the patient has, because different diseases are characterized by different temperature curves. The strangest thing about all this is that the doctors don't know what the nature of the fever is. But they know that it helps the body fight disease.

And here's how: a fever makes the body's vital processes run faster. The body produces more hormones, enzymes and blood cells. Hormones and enzymes, which are important chemicals produced inside our body, work more actively. Blood cells are more active in fighting pathogenic bacteria.

The blood circulates faster, we breathe more often, and this helps to rid the body of waste products and poisons more quickly. And it helps us fight the disease. But the body cannot afford to be feverish too often or for too long. High temperatures for 24 hours break down the proteins in your body. And since protein is a vital substance, fever can be called too "expensive" way to fight the disease.

Random interesting fact from the Great Encyclopedia:

What is the function of goose skin?

The reflex that causes goosebumps is inherited from animals. The muscles of the hair follicles contract and lift the hairs - as a result, the animal's hair stands on end. When reacting to cold, this helps to retain body heat longer, when reacting to danger, it makes the beast more massive and intimidating. In humans, in the process of evolution, there is little hair left on the body, and this reflex has no practical meaning.

Machine for thinning flowers in gardens 02.05.2024

In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers. ... >>

Advanced Infrared Microscope 02.05.2024

Microscopes play an important role in scientific research, allowing scientists to delve into structures and processes invisible to the eye. However, various microscopy methods have their limitations, and among them was the limitation of resolution when using the infrared range. But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

The new concept of the Internet from AllSeen Alliance 12.12.2013

Manufacturers of devices, network equipment and electronic components announced the creation of the AllSeen Alliance. Its goal is to develop a single industry standard through which communication between devices in the concept of "Internet of things" will be carried out. The members of the alliance call it the "Internet of Everything" and will jointly develop software and channel resources to create an open framework. It will enable device manufacturers, service providers and developers to create interoperable devices and services.

The alliance includes Panasonic, Haier, LG Electronics, Sharp, TP-Link, HTC, Harman, Qualcomm, Cisco, D-Link, Silicon Image, Canary, Fon, LeTV, LIFX, LiteOn, Moxtreme, Sears Holdings, Sproutling, The Sprosty Network, Weaved, doubleTwist and Wilocity are 24 companies in total. They will use operating systems with the Linux kernel in their solutions, and the Linux Foundation, a non-profit organization, will be responsible for software development.

Equipment and component manufacturers will use the AllJoyn open platform, developed by the world's largest chipmaker for smartphones and tablets Qualcomm, which is also a member of the alliance, as the basis for connecting devices in the "Internet of Everything" concept.

The platform is based on a network topology with a nodal structure, in which each node serves not only to transmit and receive its own data, but also as an intermediate point for data transmission between neighboring nodes.

Qualcomm chose this topology because it does not consider it necessary to connect all devices to the Internet. "When you have 2013 devices at home, you don't want all that good stuff connected to the public network," said Rob Chandhok, head of Qualcomm's Innovation Center. Qualcomm introduced the AllJoyn platform in February XNUMX. It can be used on any processor architecture and device running any operating system. Work on the platform has been going on for several years.

In addition to the platform itself, Qualcomm offers a software development kit (SDK) and case studies. It is planned to transfer data between devices using various networks, including Wi-Fi, Ethernet and the electrical network.

The Internet of Things is one of the most promising areas in the information technology market. According to the forecast of IDC, by 2020 the volume of this segment in terms of money will reach $8,9 trillion. "The impetus for the development of the Internet of Things market was provided by a number of factors," said Vernon Turner, senior vice president of IDC. "We have no doubt that the demand for related technologies and services is present both among companies and end users "We are confident that this demand will continue to grow."
