A Russian doctor explains why mood changes in the spring

In an interview with the "Izvestia" newspaper, the specialist indicated that the reason why many people feel a change in their mood and poor health in the spring is the changes in the hormonal background. It also exacerbates some diseases.

And she says, "Spring is the favorite season for many. Because in spring itself, a person's perception and perception of the world around him changes. Human behavior, emotions, mood, and health are also closely linked to the hormonal background, which can change for various reasons, including with the change of seasons. Also, the level of FSH, luteinizing hormone, progesterone, prolactin, melatonin, serotonin, and cortisol peak in the spring.”

In the spring, it is also noted that the level of the hormone directed to the body, which is responsible for maintaining the optimal level of body weight, rises. For this reason, in the spring people lose some weight quickly, the children's body grows more intensively, while the sex hormones (testosterone and estrogen) reach their peak not in the spring, but in the summer.

And she says: "Therefore, the maximum sexual activity is observed for the inhabitants of the Northern Hemisphere in the summer, and this is confirmed by the statistics of pregnancies in Europe recorded at the end of summer and the beginning of autumn. Therefore, most births in Europe for centuries are recorded at the end of winter. Also, the menstrual cycle begins in girls Usually in summer and winter, not in spring."

The expert points out that the production of the hormone melatonin, which is responsible for the speed and quality of sleep, peaks in the spring. But in the spring, the daylight hours are longer, and this hormone is not produced by the body except at night. As for the serotonin hormone, it gives the person joy and pleasure and improves the mood, while the cortisol hormone has a complex effect in the body, as it regulates energy metabolism, the immune system, thinking and the emotional background.

According to the doctor, a healthy person does not need treatment due to the hormonal changes that occur in the spring, but he needs to take preventive measures, not to disturb the daily routine, get enough sleep, follow a balanced diet, and practice physical activity. But when an excessive increase in sexual desire, abnormal aggressive behavior, and a change in appetite and weight, he should consult a specialist.

And she adds that the chronic diseases that a person suffers from can be exacerbated in the spring due to changes in the hormonal background.

Disproving common misconceptions about health risks

Dr. Alexander Myasnikov has debunked common misconceptions and horror stories that mobile phones cause cancer, and that not wearing a hat in winter leads to baldness.

And Myasnikov points out in a television program, that the claim that mobile phones increase the risk of cancer is an old myth that appeared when mobile phones were large in size (about the size of an iron), and they emit a large amount of radiation and this was a real problem.

But today's cell phones pose no danger to adults. However, according to some recent studies, radiation emitted from mobile phones can cause brain cancer in children. Therefore, it is better for them to use headphones and keep the phone away from their ears.

As for the myth that swallowing gum leads to gastritis and appendicitis, these are very rare cases.

He says, "When we swallow something, it takes 5-8 hours to leave the body. But sometimes it can cause stones without any symptoms." Generally nothing to worry about.

Myasnikov stresses that any interaction with bright screens is a strain on the eyesight. Also, a person in a lying position looks at television and other electronic devices at a different angle, meaning that the "eye movement muscle" is tense. So the eyes get tired quickly when using these devices in a lying position.

He says: "Everyone knows that when looking for a long time at the TV or the computer and other electronic devices, the person feels as if there is sand in his eyes."

Myasnikov confirms that the cold does not affect hair loss from afar or from afar.

Regarding the effect of genetically modified food on human DNA, Myasnikov says: "Theoretically, it cannot do that. In fact, we all eat products that contain genetically modified ingredients, regardless of what is written." For example, soy meat, potatoes and apples are among the genetically modified foods. Can these substances change the DNA? This cannot be denied or confirmed because we do not have the experience to draw unambiguous conclusions. There is currently no reliable data on how genetically modified products affect our bodies.

A Russian doctor explains why myocardial infarction is confused with pancreatitis

Dr. Alexander Myasnikov announced that there are common and similar symptoms of pancreatitis and myocardial infarction.

It is therefore easy to confuse pancreatitis with myocardial infarction, Myasnikov points out on a television program. Because in both cases the patient feels severe pain in the upper abdomen.

He says, "Given that there is severe pain in this area and sweating, and that the ECG shows just a curve similar to that which occurs in myocardial infarction, it becomes easy to confuse the two cases."

He adds: Therefore, the patient is transferred to the hospital, and there he undergoes additional tests, including a blood test, to determine the level of enzymes, which helps to diagnose the disease more accurately.

And he says: "If the results of the blood analysis show a clear increase in the concentration of amylase and lipase, this confirms the presence of pancreatitis."

According to him, pancreatitis is characterized by pain in the middle of the back because the pancreas gland is located in this region.

A simple scientifically proven sleep trick that can make you more alert the next day

A team of scientists has revealed a simple sleep hack that helps make us feel more alert the next morning.

Scientists said that wearing an eye mask while sleeping will enhance the alertness of the sleeper the next day.

According to the team that tested this theory, simply blocking out light, whether from street lamps, electronics or sunlight, will help avoid grogginess and fatigue.

Viviana Greco, the author of the study, described this trick as an "effective and inexpensive solution."

To check whether wearing an eye mask makes a difference, experts from Cardiff University conducted two series of experiments involving a total of 124 volunteers between the ages of 18 and 35.

In the first experiment, 89 participants were asked to wear eye masks while sleeping every night for a week, then during the second week, they slept without them.

The volunteers were asked to sleep at home and stick to their usual bedtime, so as not to change the bases of the study.

The trials were conducted over the summer because Jericho and her team "suspected that an eye mask would be most useful when it is early in the morning."

On the morning of Days 6 and 7, the participants were asked to take three different tests to measure their brain power.

The results showed that the participants performed better on cognitive exercises (such as the word association task), and their reaction time was slightly better by about 10 milliseconds, during the week they wore the eye masks.

However, the masks had no real effect in the third test of motor skills learning, which involved tapping a computer keyboard as fast as possible.

The second experiment saw 35 participants wear a device that monitors their sleep. They were asked to place a light meter on their pillows, to allow Jericho and her team to record the intensity of the light when the participants woke up.

The participants spent two nights wearing an eye mask, followed by another two nights wearing masks cut so as not to block out any light.

The sleep diaries did not show any differences in sleep hours or self-assessment quality between wearing a mask or not, according to the findings published in the journal Sleep.

"Our results speak to improved reaction times and improved memory performance," Greco told PsyPost. "The implications of our findings are significant in many daytime tasks such as driving a car or any educational or cultural context that requires learning."

The team hypothesized that the masks help sleepers spend more time in the deepest stage of sleep, also referred to as slow-wave sleep, which is thought to be important for processing new information and consolidating memory.

Studies show that this stage of sleep, which accounts for one-fifth of sleep time, restores connections between brain cells that can be overwhelming while awake. Experts believe that this process helps facilitate learning.
