water;
plastic hose;
beaker.

Lung capacity

1. How much air can your lungs hold? You'll need adult help to figure this out. Fill the bowl and bottle with water. Have an adult hold the bottle upside down underwater.

2. Insert the plastic hose into the bottle.

3. Inhale deeply and blow into the hose as hard as you can. Air bubbles will appear in the bottle. Clamp the hose as soon as the air in your lungs runs out.

4. Pull out the hose and ask your assistant to close the neck of the bottle with the palm of your hand and turn it over to the correct position. In order to find out how much gas you exhaled, add water to the bottle with a measuring cup. See how much water you need to add.

Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

The attractiveness of caring men 14.04.2024

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>

Proper breathing improves brain function 07.01.2017

Respiratory gymnastics is used for the prevention and treatment of diseases of the respiratory system, heart, blood vessels, with vegetative-vascular dystonia, diabetes mellitus, sexual disorders, as well as for weight normalization. But in the latest study, scientists found that a special set of breathing exercises improves brain activity.

A new study from the Feinberg School of Medicine and Health found that brain function improves significantly when breathing exercises are performed regularly. But to improve brain activity, it is not enough just to exercise, according to scientists, it is the rhythm of breathing that is of key importance. In addition, special equipment recorded many differences in nasal and oral breathing.

The experts were able to establish that the rhythm of breathing strongly affects the level of electrical activity, which is associated with memory processes. The experiments involved 40 people who performed various breathing exercises and tried to determine the emotional state of the people shown in the pictures. As a result, experts have found that it is easier for a person to determine the emotional state of another person during inspiration. When viewing inanimate pictures, the memory of the volunteers worked better on exhalation.

Experts are sure that inhalation is an important process not only for the respiratory system, but also for the brain. During inhalation, the activity of the amygdala changes significantly, and there is a powerful stimulation of neurons in the cerebral cortex.

In Britain, experts are sure that for good brain function it is important not only to breathe correctly, but also to lead a healthy lifestyle. According to experts, proper nutrition, avoidance of alcohol and smoking, physical activity improves the functioning of the brain, in addition, proper nutrition and exercise will even help rejuvenate the body. Such a statement was recently made by specialists from the University of Aberdeen, who, in the course of a series of experiments, found out that there is a relationship between brain and physical activity. At the same time, this relationship is constant and does not weaken or disappear over time. In simple words, if a person has a desire to lead a healthy lifestyle, then it will not be a problem for him to play sports, eat only the right and healthy food, give up bad habits, etc.

British experts are sure that the main thing is an independent decision to lead a healthy lifestyle. In this case, one cannot follow fashion, listen to friends or relatives, this decision should be a purely personal desire of a person, otherwise completely different processes begin to occur in the body and brain.

Experts recommend that everyone who wants to maintain a healthy lifestyle carefully analyze their habits, addictions, food preferences, etc. First of all, you need to adjust your diet and give up junk food. The maximum of substances harmful to the body is found in fried and fatty foods, so by giving up such products, you will take the first step not only to improve health, but also help the brain to work as efficiently as possible.
