Nail biting is a habit that many people suffer from and usually occurs when you feel stressed, bored or need to keep your hands busy.
But what some people may not know is that this widespread habit has many health damages, which we will examine in the next report, according to the American website "Business Insider".
1- Damage to the teeth

Nail biting can lead to permanent damage to your teeth and gums because the repetitive grinding that occurs between your teeth and nails can cause cracked teeth.
Additionally, it can often make teeth more likely to misalign or shift, or become brittle and fall out.​
2- Bad breath

It is almost impossible to remove all the germs and dirt from our nails, even with frequent hand washing, which means that the bacteria hiding under the nail is easily accessible due to the habit of biting.
Also, these bacteria can remain and multiply in the mouth, causing gum disease, bad breath and bad gums.
3- Diarrhea

The germs we pick up from frequent nail biting can eventually reach our intestines, causing gastrointestinal infections that can lead to abdominal pain and diarrhea.
4- Facial blisters

Nail biting can cause cracks in the skin around the nail, where wart-causing viruses can enter.
The virus can then be spread from the fingers or nails to the face by touching or biting the nails, which can lead to the appearance of warts on the face (fish eye), especially near the lip area.
5- Chronic

People who grind their nails have an increased chance of developing bruxism, or the involuntary grinding of our teeth.
People with bruxism may experience jaw pain, muscle tension, pain around the face and chronic headaches
6- Dealing with the habit of nail biting

Quitting the habit of biting nails is not very simple, but there are ways to resist the urge to do it, such as covering your fingers with gloves or keeping them busy by clicking a pen, in addition to special nail polishes nails that have a bitter taste, which help stop this habit

20231912141932579.jpg (43.08 KiB) Viewed 329 times

The German Society of Psychiatry and Psychotherapy said that winter depression falls under seasonal affective disorders, explaining that its causes lie in the gloomy atmosphere that prevails at this time of the year, represented by darkness, clouds, rain and short days.

The association added that the lack of light in winter leads to an imbalance of hormones and neurotransmitters in the brain, due to the change in the rhythm of day and night in the human body.

Its symptoms are sadness, depression, low mood, loss of motivation, lethargy, fatigue, exhaustion and nervousness, loss of appetite, sleep disturbances, poor concentration, self-neglect and isolation.

He pointed out that it can be treated with exposure to daylight, through outdoor walking tours and regular exercise.

In severe cases, a doctor may be consulted for psychotherapy or medication such as antidepressants, while it is also possible to resort to phototherapy, providing the body with ultraviolet rays, similar to sunlight

A recent study showed that if bananas are peeled, dried and ground into flour, they can be made into baked goods that taste just as mild, if not better, than wheat-based products.
Unless you're an avid reader of vegan cooking blogs or a fan of Nigella Lawson, you've probably never considered cooking with banana peels. But not only are they completely safe, scientists have shown that they're actually good for you.
When their test products were taste-tested, consumers reported that they were completely satisfied with the flavors.
You'll also get a generous boost in minerals and cancer-fighting nutrients.
The downside, adding a lot of banana peel flour resulted in a brownie with a somewhat firm texture, perhaps with all the extra fiber. But when batches were made with flour containing 7.5 percent ground banana peel, the texture of the cookies struck a more appealing balance.
The findings suggest that using banana peel flour in bread, cakes and pasta may also be worth considering.
Last year, for example, a study on banana peel cake found that the fruit's yellow skin provided natural food color to the baked product as well as a nutritional boost.
Meanwhile, a 2016 study found that replacing up to 10% of wheat flour with banana peel flour can enrich baked bread with higher protein, carbohydrate and fat content.
Eating the peel of this fruit is not only a healthy choice, but can help reduce food waste. About 40% of a banana's weight is in its skin, and most of the time, this nutrient-rich skin is discarded.
Banana peels can extend the shelf life of certain products because the peels have antioxidant and antimicrobial properties.
The same goes for other fruit peels, such as mango peel, which has also been found to boost the cake's antioxidant properties and improve its flavor. The study was published in the journal ACS Food Science & Technology

Dr. Yekaterina Demyanovskaya, a neurologist, announced that high blood pressure can lead to myocardial infarction, stroke and damage to the kidneys and eyes.

In an interview with the newspaper "Izvestia", the doctor said that it is often believed that arterial hypertension requiring medical treatment is diagnosed when the systolic blood pressure rises to 140 mm Hg or more, and the diastolic blood pressure rises to 90 mm Hg and higher. In this case, the optimal blood pressure is 120-80 mm Hg, normal - 120-129 and 80-84 mm Hg, and normal high - 130-139 and 85-89 mm Hg.

And he adds, when the level of blood pressure rises, it must be measured regularly and what is necessary to reduce it.

He says, "You should reduce your salt intake to 5 grams a day and reduce your intake of meat and alcohol. It is better if the diet contains a high proportion of vegetables, fruit, fish, nuts and low-fat dairy products. It is important to body weight is controlled to prevent weight gain'.

Treatment of high blood pressure begins with drugs when the upper pressure rises to 140-159 and the lower to 90-99 mm Hg.

He says, "Drugs to lower the level of high blood pressure are chosen for each patient according to their condition. It is not recommended to take these drugs without a doctor's advice, because instead of lowering the blood pressure level, they can have serious concequenses".

A clinical trial showed that eating 57 grams of almonds daily for a month is beneficial for athletes and that it helps to reduce fatigue and tension, reduce muscle damage and give better strength to the rear leg muscle.

The study was conducted at the University of North Carolina, involving 38 men and 26 women, over the age of 30, who were divided into two groups, the first following an almond diet and the second taking nutritional supplements.

Participants were tested at the start of the trial and after one month had followed recommendations for almond intake and supplementation.

The tests included a 90-minute intense workout to measure muscle performance and examine plasma and blood fatty acids.

According to the "Medical Express" website, the results showed that daily consumption of almonds reduced muscle damage and that those who ate almonds were better able to recover from the oxidative stress that affects muscles after intense training.

Results indicated that almonds contain nutrients that reduce inflammation and oxidative stress and improve metabolism

A study conducted by researchers revealed the best diets that protect human health, protect them from disease and help them live longer.

Diets full of colorful fruits and vegetables are an important component of longevity, with four diets being particularly effective.

Researchers from Harvard University ranked four diets of interest based on their effectiveness in reducing the risk of premature death.

And while the diets vary slightly, they all emphasize that eating more whole grains, fruits, vegetables, nuts and legumes is key.

The Healthy Diet Index was developed by the US government as the official national dietary standard and can reduce the risk of death from any cause by 19%.

This diet praises plant-based foods while ignoring red and processed meats, added sugar, unhealthy fats and alcohol.

The dietary protocol is based on a score from zero to 100, focusing on how much fruit, vegetables, whole grains, dairy products and seafood a person gets for every 1,000 calories they eat.

This diet calls for five servings of vegetables a day, four servings of fruit, five to six servings of whole grains, at least one serving of protein from nuts or tofu, and a regular serving of fish.

The Mediterranean diet is also typical of the traditional healthy lifestyle of people living in the Mediterranean. This diet is full of vegetables, fruits, legumes, nuts, beans, grains and fish.

The results showed that people who followed this type of diet had an 18% reduction in the risk of death.

How gut bacteria affect brain health

image.jpg (76.53 KiB) Viewed 303 times

A growing body of evidence suggests that the tens of trillions of microbes that normally live in the gut—the so-called gut microbiome—have far-reaching effects on how the human body functions.
The microbial community produces vitamins, helps digest food, prevents the growth of harmful bacteria, and regulates the immune system, among other benefits.
According to what was published by "Neuroscience News" citing the journal "Science", a new study conducted by researchers from the Washington University School of Medicine in St. Louis in laboratory mice shows that the gut microbiome also plays an important role in health of the human brain.
The study found that gut bacteria - in part by producing compounds such as short-chain fatty acids - influence the behavior of immune cells throughout the body, including those in the brain that can damage brain tissue and worsen neurodegeneration in conditions such as Alzheimer's disease. .
The new findings open the door to the possibility of reshaping the gut microbiome as a way to prevent or treat neurodegeneration.
"We gave young mice antibiotics for just one week and saw a lasting change in their gut microbes, their immune responses and how much neurodegeneration was related to a protein called tau that they experienced with age," said the study's senior author and professor neuroscience. , Professor David Holtzmann. One surprising finding is that "manipulating the gut microbiome may be a way to affect the brain without putting anything directly into the brain."
Evidence is accumulating that the gut microbiomes of people with Alzheimer's disease may differ from those of healthy people.
But it's unclear whether these differences are the cause or the consequence of the disease—or both—and what impact an altered microbiome might have on the course of the disease.
To determine whether the gut microbiome plays a causative role, the researchers altered the gut microbiomes of mice predisposed to brain damage, such as Alzheimer's disease and cognitive decline.
The mice were engineered to express a mutated form of the human brain protein tau, which accumulates and causes neuronal damage and atrophy in their brains by 9 months of age.
They also carried a variant of the human APOE gene, a major genetic risk factor for Alzheimer's disease. People with one copy of the APOE4 variant are three to four times more likely to develop the disease than people with the more common APOE3 variant.
"This study may provide important insights into how the microbiome influences tau-induced neurodegeneration," said Professor Linda McGovern, director at the US National Institute of Neurological Disorders.
The findings suggest a new approach to the prevention and treatment of neurodegenerative diseases by modifying the gut microbiome with antibiotics, probiotics, specialized diets or other means.
For his part, Professor Holtzmann said the findings suggest that "treatment can be initiated in middle-aged A*** while they are still cognitively normal but on the verge of disability," explaining that if treatment can be initiated in genetically susceptible A** animal models of neurodegeneration before the disease first becomes apparent and the treatment is shown to work, this may be the point at which human clinical trials can begin

Are electronic cigarettes less dangerous than regular ones?

-75405588.jpg (52.72 KiB) Viewed 299 times

It is widely believed that electronic cigarettes are less dangerous than regular cigarettes, but medical research has proven that they are not unfair. Some liquids used for electronic smoking contain more nicotine compared to regular cigarettes.

Experts pointed out that e-cigarette smoking is popular, especially among younger consumers, as it is high in addictive nicotine and carries health risks that include the possibility of heart and lung problems, but teenage exposure to it is more dangerous because the human brain is during adolescence, more sensitive, so nicotine can cause addiction, lack of attention, lack of concentration and mood disorders such as depression.

They pointed out that in recent years, the global use of e-cigarettes has increased dramatically, and despite their widespread use, there is very limited knowledge about their safety, risks and effectiveness in helping people quit smoking.

They also stressed the importance of health clinics being prepared to deal with young people's addiction to new nicotine products or what are known as e-cigarettes, with the need for stronger control of young people, especially teenagers, including a total ban on the sale of flavored tobacco products , highlighting the importance of the educational aspect regarding the harms of e-cigarette smoking and ways to stop using it.

They warned of attractive sales methods that come in different colors, with multiple names and flavors, noting that switching rates from e-cigarettes to regular cigarettes are increasing among young smokers.

Dr. Khaled Zayed Alawneh, Consultant in Cerebral and Spinal Catheterization at The King's Foundation Hospital, said: "E-cigarette smoking is very harmful for everyone, but it is high among young people, indicating that all types of tobacco, no matter how harmful, are , cause many diseases, and there is no better press than the press."

He added, in an interview with the Jordanian News Agency (Petra), that smoking e-cigarettes is harmful to everyone and at all stages of life, but its harm is more dangerous for young people than teenagers and young A*** and causes many diseases , including the respiratory system in the lungs, bronchi, brain, cardiovascular diseases and others Possibility of angina pectoris or heart attack.

He stressed that the principle is to stop smoking, either regular or electronic cigarettes, because both are dangerous to human health, noting that a simple comparison of the two types of smoking shows that they are harmful to human health, noting that electronic Cigarettes are more harmful than regular cigarettes because they contain chemicals that interact with the materials and flavors contained in it.

For his part, the consultant, Dr. Muhammad Khalil Zahran, explained that he notes that some people use both types of regular and electronic cigarettes under the pretext of quitting smoking, stressing that this is not true because the scientific study proved that only 18 % quit smoking regular cigarettes.

Zahran advised the youth not to smoke and quit smoking to maintain their health and avoid the dangerous damage it causes, noting that tobacco use is one of the risk factors for stroke, cardiovascular disease and many other diseases, apart from from the health risk. of people who are close to the smoker, especially young people. from children.

Several university youths said they use e-cigarettes to quit traditional smoking, despite knowing its harmful effects, realizing that they have become addicted to smoking through e-cigarettes, and some of them combined the two types. caused double damage to their health.

Jordan has one of the highest male smoking prevalence rates in the world

The World Health Organization-Jordan office has confirmed that smoking is one of the main risk factors for non-communicable diseases in Jordan, noting that Jordan is among the countries with one of the highest male smoking prevalence rates in the world.

He reported that according to the 2019 national progress survey conducted by the Jordanian Ministry of Health in collaboration with the World Health Organization, 66.1% of Jordanian men smoke tobacco products, in addition to 16.4% who use e-cigarettes.

The agency said on Sunday that "nicotine in tobacco is highly addictive and its abuse is a significant

Sudden vertigo requires a doctor's advice, as it can warn of a stroke, especially if it is accompanied by symptoms such as speech difficulties and visual disturbances.
The German Brain Foundation said that in this case speed of action is required, since every minute counts in saving the patient's life or in protecting him from serious permanent damage that could befall him, such as paralysis
, and this condition often requires medical attention in the intensive care unit. .
The Foundation added that the cause of vertigo is often in the middle ear, where tiny calcareous crystals important to our sense of balance slip there, causing what's known as "benign localized vertigo," which is the most common type of vertigo that occurs. in the form of a feeling of wrapping due to changing the position of the head in a way.sudden
Vertigo is often accompanied by other symptoms such as nausea, vomiting, headache and tinnitus.

This vertigo is usually treated with exercises, which restore balance to the crystals, or with medication. In advanced cases, such as obstruction of the semicircular canal, we may resort to surgery

New discovery facilitates immune destruction of cancer

2023113205442939HP.jpg (28.36 KiB) Viewed 297 times

Researchers from the Australian National University discovered that a protein called 'menin' helps turn off certain genes in cancer cells, making them visible, making it easier for the immune system to detect them.

It is believed that the results of this research pave the way for a new treatment that targets the genes that make cancer cells invisible, allowing the immune system to seek them out and destroy them.

The study was published in the journal Nature Biology and it is expected that these results will lead to an effective treatment for lymphoma and lung cancer.

"Menin has been shown to activate genes in the past. However, our research unexpectedly discovered that Menin works to keep these genes in a dormant state," said Dr. Marian Bohr, one of the 9 researchers involved in the study.

"This means that by deleting menin, we can turn on immune system genes, which are necessary to help the immune system detect and kill cancer cells," he added.
