Dand according to World Sleep Day statistics, as reported in an article published on CNN, sleep problems are “a global epidemic that threatens the health and quality of life of up to 45% of the world’s population.”

However, many believe that you can get rid of this sleep deficit by getting a good night or two, and maybe a whole week. And if we tell you that everything is wrong …

Even for young people, new research has shown that rest is not something to compensate for from time to time.

Scientific work has shown that thirteen people in their 20s who slept 30% less than necessary for 10 nights did not fully recover most of their cognitive processes after seven nights of unrestricted sleep to recover, explains an article published on CNN.

“This is a well-conducted, albeit small, multi-measure study to investigate the effects of partial sleep deprivation — primarily a study of sleep duration using pulse actigraphy, EEG changes, and cognitive function,” said physician Bhanu Prakash Kolla, a sleep specialist. medicine at the Mayo Clinic Sleep Medicine Center in Rochester, Minnesota, USA.

Add: “Reaction time improved in seven days and returned to baseline, while other cognitive tasks, including accuracy, did not fully recover.”

“The study found that there are things like memory and mental processing speed that cannot be restored that quickly,” Southern California-based sleep specialist Raj Dasgupta, assistant professor of clinical medicine at the University’s Keck School of Medicine, told CNN.

“Certainly most of the loss of sleep can be recovered, but there are things you just won’t recover quickly,” Dasgupta said.

“This is why it is so important not to have sleep debts at all.”

According to experts, the main thing is to avoid insomnia and not rest for at least seven hours a day.

Previous research

Other studies have shown that chronic lack of sleep affects the ability to concentrate, learn, be creative, solve problems and make decisions.

According to the US Centers for Disease Control and Prevention, staying awake for just 18 hours can impair your ability to drive, as if you had a blood alcohol concentration of 0.05%. 24 hours without sleep is equivalent to 0.10% (well above the US legal driving limit of 0.08%).

However, a 2017 survey found that healthy middle-aged adults who slept poorly for just one night overproduce the amyloid-beta protein responsible for the characteristic plaques in Alzheimer’s, the most common form of dementia.

A study in June this year also found that older adults with insomnia and waking up regularly at night are at increased risk of developing dementia or premature death from any cause.

CNN notes that sleep deficit is also associated with a higher risk of a host of diseases, including hypertension, weakened immunity, obesity, lack of libido, mood swings, paranoia, depression, and an increased risk of diabetes, stroke, cardiovascular disease, dementia, and more. some types of cancer.

Vladimir Putin has delayed the invasion of Ukraine at least three times.

Published

on

Putin has repeatedly consulted with Russian Chief of the General Staff Valery Gerasimov and Defense Minister Sergei Shoigu about the invasion, Europa Press told Ukraine’s chief intelligence director Vadim Skibitsky.

According to Skibitsky, it was the Russian Federal Security Service (FSB), which is responsible for counterintelligence and espionage work, that put pressure on Gerasimov and other military agencies to agree to launch an offensive. .

However, according to the Ukrainian intelligence services, the FSB considered that by the end of February sufficient preparations had already been made to guarantee the success of the Russian Armed Forces in a lightning invasion.

However, according to Kyiv, the Russian General Staff provided the Russian troops with supplies and ammunition for only three days, hoping that the offensive would be swift and immediately successful.

The head of Ukrainian intelligence also emphasized the cooperation of local residents, who always provided the Ukrainian authorities with up-to-date information about the Russian army, such as the number of soldiers or the exact location of troops.

The military offensive launched on February 24 by Russia in Ukraine caused at least 6.5 million internally displaced persons and more than 7.8 million refugees to European countries, which is why the UN classifies this migration crisis as the worst in Europe since World War II (1939-1945). gg.). ).

At the moment, 17.7 million Ukrainians are in need of humanitarian assistance, and 9.3 million are in need of food aid and housing.

The UN has presented as confirmed 6,755 civilian deaths and 10,607 wounded since the beginning of the war, stressing that these figures are much lower than the real ones.

Life sentence for former Swedish official for spying for Russia

Published

on

A Stockholm court on Monday sentenced a former Swedish intelligence officer to life in prison for spying for Russia, and his brother to at least 12 years in prison. In what is considered one of the most serious cases in Swedish counterintelligence history, much of the trial took place behind closed doors in the name of national security.

According to the prosecution, it was Russian military intelligence, the GRU, who took advantage of the information provided by the two brothers between 2011 and their arrest at the end of 2021.

Peyman Kia, 42, has held many senior positions in the Swedish security apparatus, including the army and his country’s intelligence services (Säpo). His younger brother, Payam, 35, is accused of “participating in the planning” of the plot and of “managing contacts with Russia and the GRU, including passing on information and receiving financial rewards.”

Both men deny the charges, and their lawyers have demanded an acquittal on charges of “aggravated espionage,” according to the Swedish news agency TT.

The trial coincides with another case of alleged Russian espionage, with the arrest of the Russian-born couple in late November in a suburb of Stockholm by a police team arriving at dawn in a Blackhawk helicopter.

Research website Bellingcat identified them as Sergei Skvortsov and Elena Kulkova. The couple allegedly acted as sleeper agents for Moscow, having moved to Sweden in the late 1990s.

According to Swedish press reports, the couple ran companies specializing in the import and export of electronic components and industrial technology.

The man was again detained at the end of November for “illegal intelligence activities.” His partner, suspected of being an accomplice, has been released but remains under investigation.

According to Swedish authorities, the arrests are not related to the trial of the Kia brothers.

“They can strengthen their positions. We understand that this can happen. At the same time, we do not rule out that they will announce a general mobilization,” Danilov said in an interview with the Ukrainska Pravda online publication.

Danilov believed that this mobilization would also be convened “to exterminate as many as possible” of Russian citizens, so that “they would no longer have any problems on their territory.”

In this sense, Danilov also reminded that Russia has not given up on securing control over Kyiv or the idea of ​​the complete “destruction” of Ukraine. “We have to be ready for anything,” he said.

“I want everyone to understand that [os russos] they have not given up on the idea of ​​destroying our nation. If they don’t have Kyiv in their hands, they won’t have anything in their hands, we must understand this,” continued Danilov, who also did not rule out that a new Russian offensive would come from “Belarus and other territories.” .

As such, Danilov praised the decision of many of its residents who chose to stay in the Ukrainian capital when the war broke out in order to defend the city.

“They expected that there would be panic, that people would run, that there would be nothing to protect Kyiv,” he added, referring to President Volodymyr Zelensky.

The military offensive launched on February 24 by Russia in Ukraine caused at least 6.5 million internally displaced persons and more than 7.8 million refugees to European countries, which is why the UN classifies this migration crisis as the worst in Europe since World War II (1939-1945). gg.). ).

The UN has presented as confirmed 6,755 civilian deaths and 10,607 wounded since the beginning of the war, stressing that these figures are much lower than the real ones.
