Bad habits are good for health!
Scientists have made an incredible conclusion that negative emotions and addictions strengthen human health.We have always been told that anger increases blood pressure, the use of carbonated drinks predicts extra pounds, and laziness and sloppiness indicates bad manners.
To the delight of those who do not follow the rules of the exemplary world, new research by scientists shows that many of our not the best habits can be beneficial to our own health, reports the British edition of the Daily Mail.
Anger is good for blood pressurePreviously, it was believed that anger increases blood pressure.
However, today experts say that "releasing steam" conceals some advantages. Psychologists from Carnegie Mellon University in Pittsburgh came to the conclusion that people who give free rein to irritation and react violently to stressful situations, in this way, maintain blood pressure. They also release less cortisol, better known as the stress hormone, than those who try to "blunt" their angry emotions.
Of course, it all depends on the situation. Showing anger in response to an unfair situation also helps to increase feelings of control and optimism. But an attempt to restrain rage only increases the amount of stress hormone, which in the future can provoke cardiovascular diseases.
Swearing will ease the painAt first glance, our ancestors, whose surgical operations were performed without anesthesia, can only sympathize.
However, from a scientific point of view, they were in a better position than we were.
Scientists from the University of Kiel attracted volunteers to the scientific study, who had to endure pain while swearing at the light. Psychology professor Richard Stephens believes that his research explains why obscene language is so popular today.
In his opinion, three-story swearing is the result of our adrenaline reaction, which also once helped our ancestors to fight back when the enemy attacked. "Those study participants who used foul language during the experiment had palpitations. In addition, with each swear word, the degree of their aggression increased. Therefore, it was concluded that with the growth of aggression, a person's sensitivity to pain decreases," the scientist summarizes.
Stress improves memoryWhile prolonged depression (dismissal from work during a crisis or divorce) "deplete" the immune system, American scientists from the University of Buffalo found that short stressful situations positively affect the learning process and memory.
And all thanks to cortisol (stress hormone), which affects the part of the brain responsible for memorization. During stress, the amount of glutamate (a substance that transmits information) increases, which improves memory performance.
Professor of Physiology and Biophysics Jen Yan explains this phenomenon: "The stress hormone has both positive and negative effects on the human body. Therefore, for a better life, a person needs stressful situations, but not nervous disorders."
Shirking from home cleaning will save you from allergiesThe reason for the increasing number of allergic and autoimmune diseases (psoriasis), first of all, is considered to be non-compliance with hygiene rules.
However, any kind of dirt may not be a key factor in their occurrence.
A survey conducted last year at Bristol and Brunel Universities revealed that women who often use household cleaning products during pregnancy or shortly after the birth of a child unconsciously increase their child's risk of developing asthma. Because the chemicals contained in cleaning products irritate the respiratory tract of the child.
Having studied 13,000 children aged from infants and above, experts concluded that being exposed to such chemicals at an early age, their chances of developing asthma by the age of seven increase by 41%.
Gambling will get rid of depressionGamblers are healthier and happier than those who do not like to take risks, according to scientists at Yale University in America.
According to the conducted research, weekly gambling – lotteries or horse races – psychologically harden risk takers. "The reason for this may be an increase in activity, socialization and brain stimulation," says the head of the study, associate professor of psychiatry Rani Dize.
The results of this study also coincide with the conclusions of other scientific experts investigating healthy human aging. In their opinion, gambling, in particular online poker, activates brain activity, and also stimulates participation in public life, which in the future can save from dementia and prolonged depression.
Computer games improve metabolismDespite the prevailing opinion about the dangers of a computer "epidemic", video games help to maintain the figure.
This conclusion was made by scientists from the University of Miami. For the purposes of a scientific experiment, 20 young people were connected to the devices. At the same time, they surfed the expanses of the computer game "Tekken 3" on the Sony PlayStation console. During the study, the players' heart rate increased, breathing became frequent, and they expended more energy.
Therefore, the head of this scientific project, Dr. Arlette Perry, came to the conclusion that computer games have a positive effect on human health, although they do not replace real sports. "In any case, video games are much more useful than sitting watching TV," the scientist adds.
Gaznapitki will save you from dementiaDespite concerns about the harm to teeth and figure, drinking two cans of carbonated drink a day helps protect against Alzheimer's disease, and also improves memory by 20%.
This is the conclusion reached by neurologists from the University of Glasgow-Caledonia.
In their opinion, presumably due to the sugar content, as well as elderly people suffering from short-term memory loss, students preparing for exams will be able to significantly improve the process of memorizing material.
During the study, Dr. Lee Raibi focused on a part of the brain known as the hypocampus, where a person's memories are "stored", and which is also susceptible to dementia (dementia).
Using memory tests and brain imaging technologies, experts tested young people after they consumed carbonated drinks containing at least 25 g of sugar (equivalent to a jar of "Sosa With Sugar"). Surprisingly, after such sweetening, the hypocampus showed high activity. In turn, the study participants could reproduce 17% more of the information received than before using the miracle drink.
