Bad habits that we in vain consider useful

Вредные привычки, которые мы напрасно считаем полезными

Habit is an established mode of behavior, the implementation of which in a certain situation acquires for an individual the nature of a need that “induces one to perform some actions or deeds”. When forming a habit, an action is repeatedly performed, a pleasant emotional tone caused by the implementation of this action is extremely important, since it is "learned ... that has become automatic and is performed without effort."

Harmful habits - the established way of unhealthy or incorrect behavior, the implementation of which in a certain situation acquires for an individual the nature of a need that "encourages them to perform some actions and deeds.

Each of us knows about the dangers of cigarettes and vodka and about the benefits of physical education, sports and proper nutrition. But there are habits that we make on the machine every day and do not even think about whether there is any usefulness in them. We decided to find out in which cases our ideas about healthy habits could be wrong.

Mechanism of habit formation: points of view

Psychological aspect: Habit is formed in the process of repeated execution of an action at that stage of its development, when it no longer results in K.-L. difficulties volitional or cognitive nature. Here we are talking about addiction - stopping or reducing the acuteness of a response to an irritant that still continues to act, which causes emotionally positive states during the period of habit implementation and, on the contrary, gives rise to negative experiences in circumstances that prevent its implementation. Once developed, the habit often continues to remain after the elimination of causal factors that led to its development. Behavioral psychotherapy is based on the belief that some habits can be replaced by others.

Physiological aspect: Habit is nothing more than the formation in the brain structures of stable neural connections, characterized by increased readiness for functioning. The system of such neural connections serves as the basis of more or less complex forms of behavioral acts, which IP Pavlov called dynamic stereotypes. The complex of nervous structures that provide a familiar course of action, as a rule, includes mechanisms of emotional response, which is already the psychological aspect of habit formation.

To maintain health, you need to sleep evenly

Вредные привычки, которые мы напрасно считаем полезными

Specialists from the University of Pittsburgh conducted studies that proved: to stay healthy, you need to sleep evenly. Violation of the rhythm of natural clocks leads to the development of heart disease and type 2 diabetes.

Scientists went further and measured body mass index and waist circumference in uneven sleeping people. Alas, the results did not cheer the subjects: both indicators exceeded the norm.

Healthy homemade food, fruits, juices are able to give the right amount of nutrients

Вредные привычки, которые мы напрасно считаем полезными

Healthy homemade food, fruits, juices are quite capable of giving the body the right amount of nutrients. And in the case of diseases or, for example, pregnancy, only a doctor can determine which particular vitamin or trace element the body needs.

Most of us wash very often

Вредные привычки, которые мы напрасно считаем полезными

Dermatologist from the Cranley Clinic in London, Nick Low, who conducted the study, I am sure that most of us wash ourselves very often. This seemingly good habit badly affects our health. Hot water in combination with shower gels deprive the skin of a protective layer, which leads to dryness, flaking and cracking. This may provoke the entry of infections.

If you like to wash every day, give preference to cool water and do not use detergents. They are needed in places of sweat.

Do not be with ill in the same room

Вредные привычки, которые мы напрасно считаем полезными

If you can not be in the same room with those who are ill, that's fine. But holding your breath, if your workplace neighbor coughs, is stupid. Disease molecules fly out of the human respiratory tract when coughing or sneezing at a speed of almost 5 meters per second, and their number in one “portion” is such that, if they were evenly distributed throughout the atmosphere, each inhabitant of our planet would get 2 molecules.

Do not brush your teeth after each meal.

Вредные привычки, которые мы напрасно считаем полезными

Often you can hear the recommendation to brush your teeth after each meal. In reality, this can never be done. Especially right after eating something sour or sweet. Because acid-softened enamel is easily damaged by the active abrasive substances of toothpaste.

After a snack, rinse your mouth with mouthwash or plain water. If you want to brush your teeth with paste, wait at least half an hour.

Sweet sleep after a hearty meal can have disappointing consequences.

Вредные привычки, которые мы напрасно считаем полезными

It seems there is nothing better than a sweet dream after a hearty lunch. However, an afternoon nap can have disappointing consequences, especially if you are overweight. When a person goes to bed, his body begins to save calories instead of burning them. Thus, sleep after a hearty meal with time will lead to a set of excess weight.

Do not relax immediately after a heavy meal. If you want to take a nap at lunch, first go for a 20-minute walk, so that calories have time to spend.

Do not try to turn your own house into a sterile area.

Вредные привычки, которые мы напрасно считаем полезными

Our immune system needs training. When foreign bacteria enter the body, antibodies begin to be produced, which are designed to destroy infections. If a person lives in sanitary conditions, the antibodies produced have nothing to fight with. In addition, the use of household chemicals can harm the body. For example, some air fresheners can cause chronic bronchitis.

Do not try to turn your own house into a sterile area, especially if you have children. Babies who grow up in complete purity, the likelihood of developing allergies increases greatly. Try to minimally use household chemicals, especially aggressive agents, which should be used with gloves.

Microwave helps preserve more nutrients

Вредные привычки, которые мы напрасно считаем полезными

Scientists at Harvard University believe that, unlike other ways of heating food, a microwave helps to save more nutrients. The food in it warms up faster, and therefore vitamin C and other useful elements do not have time to completely decompose.

When warming up, you need to cover the food with a lid and add a little water so that it quickly cooks, but does not overheat.

In addition, for people who adhere to a balanced diet, even the loss of certain substances due to heating in a microwave oven will be insignificant and will not affect the amount of vitamins and minerals that their body will end up with.

Sleep duration for an adult should be about 8 hours.

Вредные привычки, которые мы напрасно считаем полезными

Many people believe that the more we sleep, the better our body rests. In fact, pouring can be just as harmful as getting enough sleep. A member of the British Sleep Research Center, a professor at Loughborough University, Jim Horn, thinks that sleeping for more than 8 hours causes malfunctions in the brain. As a result, the person feels sluggish and thinks slowly.

Duration of sleep for an adult should be about 8 hours: during this time the body has time to recover. If you want to sleep more, you need to be examined, because drowsiness can be a sign of a chronic disease.

The consequences of a quick awakening can be not only a violation of the biological clock, but also harm to the heart

Вредные привычки, которые мы напрасно считаем полезными

A study in Japan shows that the consequence of a quick awakening can be not only a violation of the biological clock, but also harm to the heart. When you wake up on an alarm clock, your blood pressure rises, and you yourself instantly find yourself in a “state of alert”, which is not too good for the body.

If you really need to wake up early, and it is impossible to go to bed early for some reason, then it is better to find a way to wake up gradually to maintain good health.

Improper wearing of a backpack can lead to chronic back problems even at a young age.

Improper wearing of a backpack can lead to chronic back problems even at a young age.

The ideal position of the backpack is five centimeters above the waist, and all belts should be properly tightened. In addition, children are encouraged to put in a backpack only what is really necessary so as not to carry extra weight.

Cheap UV glasses do not protect

Вредные привычки, которые мы напрасно считаем полезными

Ophthalmologists believe that cheap UV glasses do not protect - with the same success they can not be worn at all.

As a rule, when you look at a bright light, your eyes narrowed to protect yourself, and if you are wearing glasses, your eyes open and allow the light to act on them. Cheap glasses do not have a normal protective coating, which means that they not only do not protect against sunlight, but also allow them to freely affect the eyes.
