Bad habits that we in vain consider useful
Habit is a prevailing mode of behavior, the implementation of which in a certain situation acquires the character of a need for the individual, which "prompts to perform some actions, deeds." In the formation of a habit, an action is repeatedly performed, a pleasant emotional tone caused by the very implementation of this action is extremely important, since it is "learned ... which has become automatic and is completed without effort."
Bad habits are an established way of unhealthy or incorrect behavior, the implementation of which in a certain situation acquires the character of a need for the individual, which "prompts to perform some actions, actions.
Each of us knows about the dangers of cigarettes and vodka and the benefits of physical education, sports and proper nutrition. But there are habits that we make every day on the machine and do not even think about whether they are useful. We decided to find out in which cases our ideas about healthy habits may be wrong.
Habit formation mechanism: points of view
Psychological aspect: A habit is formed in the process of repeatedly performing an action at that stage of its development, when when it is executed, no. difficulties of a strong-willed or cognitive nature. Here we are talking about addiction - the cessation or decrease in the severity of response to a stimulus that still continues to act, which causes emotionally positive states during the implementation of the habit and, on the contrary, gives rise to negative experiences in circumstances that impede its implementation. Once developed, a habit often continues to remain after the elimination of the causative factors that led to its development. Behavioral psychotherapy is based on the belief that some habits can be replaced by others.
Physiological aspect: A habit is nothing more than the formation of stable nerve connections in the brain structures that are distinguished by increased readiness for functioning. The system of such neural connections serves as the basis for more or less complex forms of behavioral acts, which IP Pavlov called dynamic stereotypes. The complex of nerve structures that provide the usual course of action, as a rule, also includes the mechanisms of emotional response, which is already a psychological aspect of habit formation.
To maintain health, you need to sleep evenly
Specialists from the University of Pittsburgh have conducted studies that have proven: to stay healthy, you need to sleep evenly. Violation of the rhythm of the natural clock leads to the development of heart disease and type 2 diabetes.
Scientists went further and measured the body mass index and waist circumference of unevenly sleeping people. Alas, the results did not please the subjects: both indicators exceeded the norm.
Healthy homemade food, fruits, juices can give the right amount of nutrients
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 what kind of vitamin or microelement the body needs.
Most of us wash ourselves very often.
The dermatologist at the Cranley Clinic in London, Nick Lowe, who conducted the research, is sure that most of us wash ourselves very often. This seemingly useful habit is bad for our health. Hot water in combination with shower gels deprive the skin of the protective layer, which leads to dryness, peeling and cracking. This can cause infection.
If you like to wash every day, give preference to cool water and do not use detergents. They are necessary in places of perspiration.
Do not be in the same room with a sick person
If it is possible not to be in the same room with the sick person, that's fine. But holding your breath if a workplace neighbor coughed is silly. Pathogenic molecules fly out of a person’s respiratory tract when they cough or sneeze at a speed of almost 5 meters per second, and the number of them in one “portion” is such that if they were evenly distributed throughout the atmosphere, each inhabitant of our planet would have 2 molecules.
Do not brush your teeth with paste after each meal
Often you can hear the recommendation to brush your teeth after each meal. In reality, this should never be done. Especially immediately after eating something sour or sweet. Because enamel softened with acids is easily damaged by the active abrasive substances of toothpaste.
After a snack, rinse your mouth with rinse aid or plain water. If you want to brush your teeth with a paste, wait at least half an hour.
A sweet dream after a hearty meal can have disappointing consequences.
There seems to be nothing better than a sweet dream after a hearty meal. 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 in reserve instead of burning them. Thus, sleep after a hearty meal over time will lead to weight gain.
Do not relax right after a heavy meal. If you want to take a nap for lunch, first go for a 20-minute walk so that calories can be spent.
Do not try to turn your own home into a sterile area.
Our immune system needs "training." When foreign bacteria enter the body, antibodies begin to be produced that are designed to destroy the infection. If a person lives in sanitary conditions, the developed antibodies have nothing to fight with. In addition, the use of household chemicals can also harm the body. For example, some air fresheners can cause chronic bronchitis.
Do not try to turn your own home into a sterile area, especially if you have children. In babies who grow up in full purity, the likelihood of developing allergies increases greatly. Try to minimize the use of household chemicals, especially aggressive products that should be used with gloves.
Microwave Helps Save More Nutrients
Scientists at Harvard University believe that, unlike other ways of heating food, a microwave helps to retain more nutrients. The food in it warms up faster, and therefore vitamin C and other beneficial 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 cooks quickly, but does not overheat.
In addition, for people who adhere to a balanced diet, even the loss of certain substances due to heating in the microwave oven will be insignificant and will not affect the amount of vitamins and minerals that their body will end up with.
Duration of sleep for an adult should be about 8 hours
Many people believe that the more we sleep, the better our body relaxes. In fact, sprinkling can be as harmful as lack of sleep. Jim Horne, a researcher at the British Sleep Research Center, professor at Loughborough University, believes that sleep longer than 8 hours causes a malfunction in the brain. As a result, a person feels lethargic and slowly thinks.
The duration of sleep for an adult should be about 8 hours: it is during this time that the body manages to recover. If you want to sleep more, you need to undergo an examination, 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
A study in Japan shows that the consequence of a quick wake up can be not only a violation of the biological clock, but also harm to the heart. When you wake up on an alarm clock, 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 going to bed early for some reason is impossible, then to maintain good health it is more useful to find a way to wake up gradually.
Wearing a backpack incorrectly can lead to chronic back problems, even at a young age.
Incorrect 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 must be properly tightened. In addition, children are recommended to put in the backpack only what is really necessary so as not to carry unnecessary weight.
Cheap UV glasses do not protect
Ophthalmologists believe that cheap glasses do not protect against ultraviolet radiation - with the same success they can not be worn at all.
As a rule, when you look at a bright light, your eyes squint to protect themselves, 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.
