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.

“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.”

“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.

HIn early April, a car with civilians leaving Melitopol passed a Russian checkpoint in the occupied city of Vasilyevka in Zaporozhye, at which point a Russian serviceman approached the car and saw a teenager checking something on his mobile phone.

What are you doing, filming me? the soldier asked before taking his cell phone and pulling him out of the car. “Should I shoot him right now or smash his phone?” he shouted, pointing the gun at the boy.

The man dragged the teenager into the nearest yard where Russian troops were based, leaving those in the car speechless and frightened.

After an hour of checking his identity, the Russian military realized that he was Vladislav Buryak, the son of one of the highest Ukrainian officials in the region, Oleg Buryak, head of the state administration of the Zaporozhye region.

Israel bombs Gaza after ceasefire in response to Palestinian rockets



“In response to rocket attacks on Israeli territory, the army is currently attacking a large number of targets belonging to the Islamic Jihad terrorist organization in the Gaza Strip,” the Israeli army said in a statement sent at 21:33.

In addition, air raid warning sirens were turned on in southern Israeli cities near the Gaza Strip.

“The sirens sounded in the sector adjacent to the Gaza Strip,” the same military statement said late on Sunday.

The Egyptian-brokered ceasefire included Cairo’s commitment to “work towards the release of two prisoners,” Mohammed Al-Hindi Bassem Saadi and Khalid Awadeh, head of the JIP’s political wing, said in a statement.

Last Monday’s arrest of Bassem Saadi, the leader of the Palestinian Islamic Jihad in the West Bank, which has been occupied by Israel since 1967, led to the current outbreak of violence.

The Israeli army launched an operation on Friday, billed as a “preemptive strike” against Islamic Jihad, in which its top military leaders in Gaza, Taysir al-Jabari and Khaled Mansour, were killed, as well as several fighters of the group.

The deaths of the military leaders were confirmed by the Islamic Jihad organization, which Israel, the United States of America and the European Union consider “terrorist”.

Israeli Prime Minister Yair Lapid said the Gaza operation would continue “for as long as necessary”, calling Saturday’s attack that killed Khalid Mansour an “extraordinary result”.

Israeli authorities justified the operation, launched on Friday, on fear of reprisals from Islamic Jihad after Bassem al-Saadi was arrested on August 1 in the West Bank, a Palestinian territory occupied by Israel.

Over the past two days, about 40 Islamic Jihad members have been arrested by Israeli forces in the West Bank.

Before the Islamic Jihad announcement, the Palestinian armed movement fired several mortars at Israel and Jerusalem, which, according to its army, were intercepted by the Israeli missile defense system.

In the Gaza Strip, 17 Palestinians, including nine children, were killed today in Israeli army raids in Jabaliya, Gaza City and Rafah, according to the Palestinian armed movement Hamas, which is in power in the enclave, which has been under an Israeli blockade for more than 15 years. . .

Since the start of this Israeli operation against Islamic Jihad on Friday, “43 Palestinians have been martyred, including 15 children” and “311 people have been injured,” according to the latest Hamas health ministry report.

The director of the Al-Shifa hospital in Gaza said that the institutions under his supervision urgently needed medicines and electricity to continue caring for the wounded.

Gaza’s only power plant was shut down on Saturday due to fuel shortages, four days after Israel closed roads connecting the enclave, citing security concerns.

Before the mortar attack today, sirens were sounded from Gaza regarding shells in Jerusalem, Tel Aviv and Ashkelon.

The clash between Israel and Islamic Jihad is the worst since the clash between Israel and Hamas in May 2021. According to local authorities, 260 Palestinians, including militants, and 14 Israelis, including a soldier, were killed in 11 days. .
