A wake-up call .. Sleeping too long can be devastating and affect the mind



A wake-up call .. Sleeping too long can be devastating and affect the mind

Dozens of studies and scientific research have been conducted over a long period of time and have concluded the importance of getting plenty of sleep.

A good night’s sleep helps our bodies adjust to themselves and function as they should, and this is linked to improved mental health and reduces the risk of many health conditions, including heart disease and diabetes.

Lack of adequate sleep has also been shown to be associated with conditions such as cognitive impairment and Alzheimer’s disease.

Surprisingly, however, too much sleep can damage our brains, according to the website of Science Alert.

Prolonged sleep can also be harmful

Researchers at the University of Washington School of Medicine have published a research paper that suggests that prolonged sleep may be associated with cognitive decline, as well as less sleep.

The research team wanted to find out how much sleep is linked to cognitive impairment over time. To do this, they looked at adults from the mid-70s to the late 100s on average, and followed them for four to five years.

During their study, 88 people showed no signs of dementia, while 12 showed signs of cognitive impairment (one with mild dementia and 11 with mild cognitive impairment before).

During the study, participants were asked to complete general cognitive and neurological tests to detect signs of cognitive decline or dementia.

Subsequently, the results of these tests were combined into a single score, called the Premature Alzheimer’s Cognitive Disease (PACC) score. The higher the score, the better their opinion over time.

For four to six nights, sleep was measured using a monopolar electroencephalogram (EEG) worn on participants’ foreheads during sleep.

This was done once three years after people first completed their annual cognitive tests. This electroencephalogram allowed researchers to accurately measure brain function, which would tell them whether a person was sleeping (for how long) and how restful that sleep was.

Although sleep was measured only once during the study period, it still gave the research team a good indication of the participants’ normal sleep habits.

When using an EEG to measure the activity of the brain, people may become somewhat disturbed to sleep on the first night as they become accustomed to the device, and sleep will return to normal the next night. That is, when sleep is monitored from the second night onwards, it is a good representation of a person’s normal sleep habits.

The researchers also looked at other factors that could affect cognitive decline, including age, genes, and whether a person has symptoms of beta-amyloid or Dow proteins, both of which are linked to dementia.

Overall, the researchers found that sleeping less than 4.5 hours and more than 6.5 hours – with poor sleep – was associated with cognitive decline over time.

Interestingly, the effect of sleep time on cognitive function was similar to age, which is the greatest risk factor for cognitive decline.

We know from previous research that insomnia is associated with cognitive decline. For example, a study shows that people who report sleep disorders, such as insomnia or excessive daytime sleepiness, are more likely to develop dementia than those who do not.

Other research shows that beta-amyloid is high in the brains of people with short sleep patterns – a condition commonly found in the brains of people with Alzheimer’s disease.

Researchers are not sure why poor sleep is linked to cognitive decline. One theory is that sleep helps our brain flush out harmful proteins that form during the day.

Some of these proteins – such as beta-amyloid and Dow – are thought to cause dementia. So interfering with sleep can interfere with our brain’s ability to get rid of it. Experimental evidence also supports this – showing that even a night’s sleep can temporarily increase beta-amyloid levels in the brain of healthy people.

But it is not clear why long sleep is associated with cognitive decline. Previous studies have found an association between increased sleep and cognitive performance, but most participants relied on self-reporting how long they slept at night – meaning the data were less accurate than using EEG to measure brain function.

Therefore, this new study adds weight to such findings. Surprisingly, the results of this study show that better sleep duration is much shorter than previous studies have indicated that it is complicated.

Studies show that sleeping more than 6.5 hours is associated with cognitive decline over time – less so when we consider that older people are advised to sleep 7 to 8 hours each night.

The reason is that the length of sleep is not necessary, but the quality of that sleep is important when it comes to the risk of dementia. For example, this study shows that “slow” insomnia – restored sleep – especially affects cognitive impairment. What we cannot say from this study is whether long-term sleep can predict cognitive decline independently.

Importantly, we cannot rule out that participants who slept more than 6.5 hours each night may not have had cognitive problems prior to brain changes indicating dementia that was not picked up on the tests.

Although researchers are interested in correcting the factors associated with dementia, there may be other conditions that precede those who sleep longer, which may have contributed to a cognitive decline that is not taken into account. These include, for example, poor health, socioeconomic status, or level of physical activity.

Taken together, these factors may explain why long sleep is associated with cognitive decline.

“The Terna tragedy is a warning of the worst.” Haji reveals the reasons for the increase in disasters in Arab countries



“The Terna tragedy is a warning of the worst.”  Haji reveals the reasons for the increase in disasters in Arab countries


Dr. Space Scientist specializing in Earth and Planetary Sciences. Issam Hajji blamed the increase in natural disasters such as earthquakes and floods in Arab countries on lack of awareness of climate change and lack of specialized research and monitoring stations. Poor urban planning.

In the episode dated (10/2/2023), “The Story Has the Rest” highlighted recent disasters affecting the region, such as the two devastating earthquakes that struck southern Turkey and its aftermath in the Middle East. February 2023, and the Al Houze earthquake in Morocco in September. From the same year, Libyan floods wreaked havoc in the coastal city of Derna, days after the Moroccan earthquake.

Haji said the Terna flood disaster was not the worst but a bad warning, pointing out that it was a copy of what happened there in 1925 when a storm in the Gulf destroyed naval vessels there. Famine and about the same number of casualties caused the death toll.

Hajji published maps of Terna after Hurricane Daniel, reviewed rainfall rates, and emphasized that the storm did not penetrate deeply, but caused large amounts of dust to move from the interior to the coast, stressing that the environmental risk lies in rebuilding by removing millions. cubic meters of soil.

He revealed that the Arab coastal cities of Alexandria in Egypt, Tangier in Morocco and Manama in Bahrain are losing their battle in light of the escalation of climate change and the short-term recurrence of recent decades in the Mediterranean region. For example, there is a lack of awareness of these risks and population growth in the region.

The Egyptian scientist made frequent stops in Alexandria, which he said had changed from a historically disaster-resistant city to an area at risk in the past 20 years, pointing to the danger of building in floodplains that have led to the degradation of the urban landscape. In a coastal town.

Population density risks

In his speech, Hajji said that the majority of the people of the Middle East and North Africa (92%) settled in 3% of the total area of ​​the Arab world, before confirming that there had been a major collapse in climate and scientific knowledge, which caused most of the disasters.

In the same context, studies indicate that about 30 million residents of the Arab world are exposed to high risks of future catastrophic earthquakes.

The project uses artificial intelligence technology and satellite maps to broadcast images of the massive destruction that climate change can cause to infrastructure, such as storms entering coastal areas, wiping out everything in its path.

Hajji emphasized that there are solutions to climate change, “It is not the end of the universe and humanity, but rather the risk of dealing with it.” He pointed to a development project between the Universities of Munich and California, Khalifa University in Hamad bin Qatar and NASA to create a coastal zone in the Arab region “that will resist climate change”.

Haji offered some solutions to combat this climate change, including reforestation, the placement of what he called sand dunes, and “scientific” management of the coastal area.

Document image

The program aired a short documentary retracing the Arab region’s history with natural disasters, and stopped frequently to learn about the earthquake belts surrounding Arab countries with Arab and foreign experts. The film also traces the experiences of Chile and Japan in dealing with a series of earthquakes, particularly in the Asian country, which experiences two thousand earthquakes a year without any significant impact.

The film also covers the scientific views of leading experts from both countries on how to monitor earthquakes, the development of earthquake-proof building standards and flexibility of structures, ensuring that buildings absorb earthquakes.

Experts – who spoke during the film shown by the program – pointed out that Japan has earthquake sensors that help to initiate early evacuation measures, and that Tokyo has developed building codes with 3 levels: the first is related to steel supports, and the second is related to dampers that absorb earthquake energy and reach the third level. isolate from

For the Arab world, seismologists discussed conflict zones and their classifications and Arab countries at risk of earthquakes because 3 major earthquake belts pass through or near the region, namely the East African belt, the Alpine belt, and the Dead Sea fault, with the latter being the most active. Considered, and the countries concerned are Syria, Lebanon, Palestine and Jordan.

Experts revealed that there is a seismic index in the Arab world, but in addition to the slow development in the Arab region, it is a serious challenge, especially in cities with high population density, adding that “houses are the first cause of the increase in the number of collapse victims”.

They pointed out the importance of focusing on population distribution, disaster management plans and taking into account seismic risk and the fragility and unreliability of buildings, especially in the absence of an Arab earthquake monitoring network.

Study: University students are more stressed than their peers.. and why?  |  Other |  DW Arabic Window on Celebrity Lives and Fun Facts |  T.W

Studying is not always a pleasant journey of knowledge and learning. This is a difficult stage that requires many sacrifices and sometimes it becomes a station of suffering, especially with very difficult majors or being forced to persevere with limited or almost non-existent financial income while the student is in university.

A new study suggests that university students are more likely to experience stress than their working peers, and that the main reason for this is the financial problems students face.

According to a Guardian newspaper report from the study’s author, Dr. Tayla McCloud The relationship between mental health decline and learning, coupled with anxiety due to increased financial pressures and the need to achieve strong results.

Students in many parts of the world are forced to pay extra to rent rooms and apartments in addition to rising living costs, including food prices and prices of restaurant and cafe services, transportation, due to inflation and high energy costs. and many others.

The research paper was published in the public health journal The Lancet, and its authors also stated that at age 25, the end of the university years, mental health differences between graduates and non-graduates no longer existed.

The study suggests that if the causes of depression among students are identified, it is possible to reduce depression and anxiety among 18- to 19-year-olds.

Dr Gemma Lewis, assistant professor at the same college, points out that poor mental health in students can have long-term consequences in their lives. “The first years of higher education are important for self-development, so if students’ mental health is improved, positive long-term effects can be expected on their health, well-being, academic achievement and success.”

The study’s findings are consistent with another study conducted by King’s College London, which found that mental health problems among students had almost tripled in recent years, rising from 6% to 16%, and was particularly high among women and non-binary students. People, and one reason for this was the high cost of living.

One of the consequences of these problems is that students think about leaving university purely for financial reasons, while others work more during their studies, which also has a negative impact on mental health.
