Children’s science questions also consider teasing-related headaches, tasting food outdoors, and the amount of human blood. What about a cat itching?

Coronavirus pandemic has been demanding sacrifices from us for almost two years.
Adherence to recommendations and guidelines requires perseverance and patience. When a pandemic continues in spite of everything, we are easily frustrated and disappointed.
We are tired of masks, hand washing, keeping distance, quarantine and the whole coronavirus.
For some people, frustration can become so great that it even leaves them with all the safeguards. The reason for this is often that even getting sick is thought to be easier than complying with restrictions.
When you get used to the threat of an illness, the illness may seem less threatening than it really is. It may be thought that the authorities are wrong or exaggerate the threat of the disease.
However, according to the latest information, only less than five per cent of all people do not comply with protection measures in Finland, ie very few. So, fortunately, the vast majority comply with the restrictions.
Just over half of Finns enforce restrictions well and about 40 percent fairly well. Many who adhere well to restrictions think that people have a right to be angry and frustrated, but it is still important that we are able to comply with restrictions.
Instead of giving up safety gaps, masks and other means, we can discuss with loved ones, for example, how we would like to throw a pandemic away. It helps to cope with restrictions even longer – as long as there is a need.

Teasing can cause a state of stress that triggers a headache.
Why does your head start to ache after being teased for a long time? Especially if you are crying and shouting?
Vanamo Herranen, 8
Different In humans, very different causes can trigger headaches, such as control or certain foods. Stress is also one of the most common causes of headaches.
This is probably due to the fact that stress causes the body to make extra secretions of so-called stress hormones. In some people, they cause headaches.
On the other hand, the cessation of stress and the resulting decrease in stress hormones, for example at the beginning of the weekend, can easily cause a headache in some people.
Prolonged teasing can, for good reason, be considered a stressful situation for the body. If the teasing is accompanied by crying and shouting, the stressful situation is easily particularly intense. On the other hand, incubating inside a heater can also increase the risk of headaches over a longer period of time.
By the way, it is also known that crying without teasing causes headaches in some people. However, it would seem to be related only to crying from grief or anger, and not, for example, from crying for joy or causing tears to cut the onion.

During the trip, lunch will taste good and can be influenced by a nice company.
Why does food taste better outdoors than indoors?
Klaus Kairi, 7
Outside you usually move more than inside, which increases your hunger.
Outdoor dining is also often given more attention. When dining is an important program number, its importance grows greater than on a regular day at school or at home.
Researchers have estimated that the eating environment can affect the taste experience even more than the food itself. As a dining environment, the outdoor air is quite special. There you see, smell, hear and feel completely different things than inside.
Even outdoors, the senses are often sensitized to receiving experiences more than usual, which means that food may be experienced more holistically.
Even a fun outdoor club greatly affects the dining experience.
In addition, camping food may be something a little better than home or school food. The picnic snacks may have been made yourself, or they are special delicacies chosen for the trip.

In some blood disorders, the treatment is to remove the excess blood.
Can a person get too much blood?
Elsa Alavillamo, 9
Normally in the human body, the production and removal of blood is tightly regulated. Thus, a healthy person usually has an appropriate amount of blood.
We have about 6 to 8 percent of our weight in our blood. For example, a child weighing 30 kilograms has about two liters of blood, or two cans of milk.
However, sometimes there may be too much blood. Excessive blood volume is usually caused by the body not balancing salt and fluid normally.
For example, if the kidneys are not working properly, fluid will build up in the body and blood volume will also increase. Excessive salt intake can also slightly increase blood volume.
In some blood diseases, there is too much blood, although the actual amount of blood does not change. This is due to a significant increase in the production of blood cells and congestion in the bloodstream.
About 200 billion red blood cells carry oxygen every day. It is a disease in which more and more red blood cells are produced. It is treated by removing an appropriate amount of blood from the body at regular intervals.
Leukemias, on the other hand, have too many white blood cells. Some so-called myeloproliferative diseases, in turn, have too many platelets. They require other treatments instead of bleeding.

Cats seem to like being touched.
When I scratch my cat, can it sometimes itch?
Venla Series, 5
Cats handsome mustaches are their most visible sensory. The touch of the tip of the mustache is transmitted to the sensitive sensory nerves of the base of the hair. They respond to even minor movements of the hair and transmit information about them to the cat’s brain.
In addition to the head, cats have tactile hairs all over their bodies. The tactile hairs are not very different in size and appearance from ordinary hairs, so it is difficult to distinguish them from the fur.
Because humans don’t have the same tactile hair as cats, it’s hard to say exactly how the touch feels to them.
In any case, ironing and scraping are conveyed to them as a clear sense of touch. It may also be accompanied by a slight feeling of pressure on the skin. That feeling is transmitted to the brain by the sensory nerves in the skin.
Cats are particularly sensitive to touching the head area such as the forehead, cheeks and lower jaw. They may feel it as a pleasant tingling or itching, especially if it is done by someone they know.
The experience is transmitted to the central nervous system that controls the cat’s activity, apparently through sensory nerve fibers and special pain nerve fibers called C-fibers.
When a cat experiences pleasure from touching its head, it easily rumbles to spin. However, there are always exceptions. Some cat individuals may find the discomfort uncomfortable.
