Why do we get cooler if we fan ourselves?

When you feel cold or hot, you actually feel the temperature of your blood! Our body has an average temperature of 37 degrees Celsius, regardless of the temperature "outside". But that doesn't mean your core temperature isn't going down and up. Sometimes it happens. But whatever these fluctuations, our body always strives to return the temperature "to normal". This process is regulated by a center in the brain that raises the temperature of the blood if it is low and lowers it if it is too high.

Suppose your blood temperature has dropped. Your sympathetic nervous system kicks into action immediately. Certain glands begin to secrete enzymes so that the process of burning oxygen in the muscles and liver goes faster. The blood vessels in the skin constrict so that our body gives off less heat. If the temperature drops too much, the muscles become active and you begin to shiver. This reaction of the body is aimed at producing heat.

Now suppose your temperature has risen. The process of oxygen combustion slows down, the vessels of the skin dilate to release excess heat and help sweat evaporate. When a liquid evaporates, that is, it passes into a gaseous state, heat escapes with it. This is what happens when you sweat. The sweat released from the pores on your skin acts like a shower that washes your body both inside and out. It is excreted from the body in microscopic droplets through millions of tiny holes.

If the air around your body is moist, sweat will stop evaporating. Your body doesn't seem to cool down at all. But when you start fanning, the air in the immediate vicinity of your skin begins to move and the sweat evaporation process accelerates. Your body starts to lose heat and you become cooler.

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 ... >>
