VR may cause vomiting – Because of motion sickness
VR may cause vomiting – Because of motion sickness – In order to fully enter the virtual reality,
one has to deceive not only the eyes but also the other senses. This is also the reason why
many virtual reality users can cause problems with motion sickness. Then the impressions
received by the liar do not agree with the visual stimulus. In motion sickness,
the eyes see that the body is not moving, and that the labyrinth registers continuous motion,
tilting and acceleration, in the case of nausea caused by virtual reality is quite the opposite.
Eyes see the perfect simulation of space, covering the entire field of view.
However, the brain does not record any motion signals from the labyrinth or other senses.
In both cases there is a sensual dissonance that causes malaise, dizziness, fatigue,
and even vomiting.
Three most common allergies – Causes of allergy development
Three most common allergies – causes of allergy development – Regardless of what causes allergy,
it is always inadequate reaction of the body. Allergy is considered a disease of civilization.
Which affects approx. 20-30% of people, and this number is constantly growing.
Recent studies indicate that the risk of developing allergies carry the genes.
Food allergies: In the food allergy is caused primarily by protein. Allergens work even after heat treatment and after passing through the digestive tract. The spectrum of food allergies is very wide. Mostly allergic to eggs, fish, hazelnuts, milk, celery, fruit, vegetables, flour, peanuts, meat, potatoes and cocoa.
Pollen allergies: This is one of the most common types of allergies. Its occurrence is related to the flowering of plants, whose pollen is the patient’s allergen. Most often they are grass pollen, less common perennial, shrubs and trees. Sometimes the disease persists throughout the year, but during the flowering of the plant. Symptoms such as swelling of the mucous membranes, rhinitis, tearing, and breathing difficulties occur.
Animal allergies: The most common is allergy to cats, dogs, rabbits, hamsters, horses and exotic birds. Allergens in this case are skin or fur. However, allergens can also cause faeces, urine and saliva of animals.

First treatment raw penicillin – Bactericidal effect discovery
First treatment raw penicillin – Bactericidal effect discovery – In 09.01.1929 in London first applied
treatment raw penicillin. Bactericidal effect of mold penicillinum discovered Sir Alexander Fleming.
Human body bacteria – Weight of digestive tract microorganisms
Human body bacteria – Weight of digestive tract microorganisms – The total weight of bacteria
living in the human digestive system is approx. 1.5 kg. In the large intestine,
we have 100 trillion microorganisms. 10 times more than the number of all cells in the body.
They are divided into roughly 400 species.
Studies have shown that it is the changes in the number and species of bacteria in the gut
have a negative impact on the psyche of the patients. According to specialists bacterial flora
may be responsible not only prone to depression, but depression symptoms in themselves.
At one cm square elbow stays on average 10 thousand. bacteria – 113 different species,
but more than 90% are 10 of them. The least bacteria on human skin found between the toes,
the largest habitat of the navel.
Old age mental activity – number of neurons
Old age mental activity – number of neurons – The decrease in mental activity in old age
was attributed to the decreasing with age, the number of brain cells.
Neurologists from universities in Boston and Washington, however, proved.
That almost all of the 10 billion cells used while thinking, they are active even in 80-year-olds.
Alcoholism effects – Repairing damaged neurons
Alcoholism effects – repairing damaged neurons – Scientists from Wurzburg in Germany
found that damage to brain cells caused by excessive alcohol consumption can be repaired only partially.
They note that in the interest of alcoholics is the fastest return to sobriety. Longer heavy drinking
causes brain regeneration proceeds with great difficulty.
Impact hair thinking – Hair arranged in the left side
Impact hair thinking – Hair arranged in the left side – Researchers from the University of Bonn
have discovered that only a small part of the population. Hair around the crown arranged to the left.
They proved that the hair arranged in the left side may have a similar effect on the functioning of the brain
as writing with left hand. Thus confirming the theory that describes the stacking of hair left
almost exclusively left-handed persons.
Men and women brains weight differences
Men and women brains weight differences – Researchers under the direction of Paul Farmer
of Harvard Medical School in the US have shown that the size of certain parts of the brain in women
is different from the same part of the brain in men. The frontal lobe in which the center of
decision-making and problem-solving, weighs more in women than in men. More space is also an area responsible for short-term memory and spatial orientation.
