Study: Women Need More Sleep Than Men Do

More SleepPeople have various need as to their sleep duration, as well as to the time they must go to sleep and get up. Sometimes, even the most loving and understanding husband and wife can have really different needs in their sleep routine: the wife can like going to sleep early in the evening and waking up early in the morning, but the husband can have a habit of going to sleep late and waking up late, too. Hopefully, these differences will not interfere with their relationship and life. However, those things could be the issues for another study. Nowadays, a group of scientists came up with the conclusion related to our sleep duration and the need of sleep. According to the findings of a, expert group at Duke University in North Carolina, USA, women need more sleep compared to men. That is why those women who sleep as much as men very often wake up grumpy and not properly rested.

The scientists collected information on sleep habits, sleep patterns and other related data on 210 study participants, both men and women of different age and status. After analyzing the collected data, it became apparent that if women sleep as much as men, they always wake up more aggressive, angry and hostile. At that, all women reported about feeling tired and restless after not sleeping as much as they need, and the scientists came to the conclusion that such women suffered both physically and mentally as a result of insufficient amounts of sleep. At the same time, men did not report similar effects after having a small sleep deprivation. “The study suggests that poor sleep – measured by the total amount of sleep, the degree of awakening during the night, and most importantly, how long it takes to get to sleep – may have more serious health consequences for women than for men,” Edward Suarez, the study leader said.

After discovering this association, the researchers tried to look closer at the issue and find possible causes and factors that play a role in the discovered phenomena. They developed a theory that possibly, the hormones can be behind the differences between sleep needs of men and women. With age, more and more women experience hormonal shifts and changes linked to the approaching menopause and other processes in their body. Obviously, men do not suffer the same kind of changes. That is why, the scientists are convinced, women need more sleep and must do everything possible to avoid a lack of sleep since it is linked to much higher level of distress and increased levels of hostility. Actually, the experts are convinced that it is impossible to say that men do not suffer from distress and feelings of tiresome if they have a lack of sleep. But the stated links are much stronger in women.

Certainly, it is not the first study of the effects of sleep deprivation and insufficient amounts of sleep on women. It was discovered before that those modern time’s ladies who suffer from chronic lack of sleep and other sleep disorders have quite high risks of chronic depression and developing serious cardiovascular problems. Compared to men, women were found to be more prone to the mentioned risks. There is no need in mentioning negative effects of poor sleep on women’s skin and beauty. Therefore, those ladies who want to look stunning, remain beautiful for many years, avoid stresses and depression, as well as prevent serious health conditions should do everything possible to guarantee themselves good night sleep of at least 7.5 – 8 hours a day. It is also strongly recommended to go to sleep and wake up at the same time every day, regardless of its being a week day or a weekend day.

Our Sleep Phases Depend On Our Body Clock

Sleep PhasesYou must know very well that sometimes, regardless of our being an owl or a lark, it can be easy to wake up early in the morning and start our working day in a good shape. But sometimes, even if you are used to waking up with the sunrise and flying out of your bed with a smile, you are literally unable to open your eyes and begin your day full of energy. It is quite a common issue in our times, and there are plenty of causes of that: chronic stresses, our common lack of physical activities and improper nutrition, getting out of bed too early in the working days and staying in bed too late in the weekends, as well as other sleep imbalances and disorders which most of us are having now. A great deal of modern people admit that they have serious problem with waking up early in the morning, and most of those are convinced that improper sleep or feeling too sleepy in the morning affects their productivity and efficiency to a great extent.

In particular, according to the latest statistics, about 15 per cent of today’s teenagers reported feeling too sleepy in the morning, so they come to school not properly awake. The issue became a point of interest of a scientific team at Flinders University in Adelaide, Australia, and the experts decided to look closer at the phenomena they called ‘delayed sleep phase disorder’, defined by the authors of the study as a condition when a person can not fall asleep at night and can not wake up in the morning at a conventional time. After collecting some information and analyzing sleep patterns of some people in Australia, the scientists came to the conclusion that such thing as our own body clock can be responsible for the problem. According to Professor Leon Lack, one of the study leaders and the author of the report, those people who have delayed body clock which run longer than 24 hours are most likely to suffer from such problem.

‘Most people have a 24-hour body clock, it’s a natural rhythm that influences sleepiness and core body temperature but for people with delayed sleep phase disorder it takes longer to complete the cycle so they tend to go to bed later and wake up later.’ Professor Lack underlined that in those people whose body clock works normal are usually informed about the time to get up by the amount of sunlight or daylight coming to their bedroom. However, since we are using blinds or heavy curtains, the body does not receive these simple natural signals on time. That is how body clock imbalances start, leading to various sleep disorders and decreased sleep quality. That is, in turn, linked not only to decreased productivity and a lack of success, but also to poorer health, lower life quality, and more stresses. Unfortunately, the problem is sometimes much more serious that it may seem, and it affects overwhelming majority of people around the world.

At that, as the expert is convinced, such constant disruptions in circadian rhythms and other factors turn the mentioned sleep disorder into a chronic problem which can sometimes be very hard to get rid of. The only possible treatment proposed by Professor Lack and his scientific team is a special therapy involving exposing people to a bright light in the beginning of the day. This can be an effective approach to informing the body clock about the necessity to work faster and restoring the natural original circadian rhythms of people. However, further studies and experiments are necessary to prove the effectiveness of the proposed therapy. Professor Lack underlines that it is essential to keep in mind that this serious condition affects many people’s life and should be never overlooked. ‘It causes young people to be late for school and when they do get to school they’re inattentive until their body clock finally wakes up. Adults can also have trouble holding down jobs because they’re always running late for work so it does have a detrimental effect on lives,’ he stated.

The Most Common Lack Of Sleep Causes

Lack Of Sleep CausesThe problems of chronic insomnia and a constant lack of sleep have turned into a real curse for many modern people. Many scientists and experts agree to the fact that those of us who live in big cities are at the highest risk of suffering from this kind of problems compared to the people who live in rural areas. Certainly, those who live in big cities spend most of their times indoors, in the offices or at other workplaces. They are more prone to suffer from stresses as they live a more active business life. They lead less active lifestyle compared to those people who live outside of big cities and mostly spend their time outside. Actually, there is plenty of lack of sleep causes which bring to chronic insomnia and more serious sleep disorders in modern people who live in big cities. Let’s try to look close to the most important and the most influential factors that cause us tossing and turning in our beds all night instead of having a peaceful and restful sleep.

Experts say that about 20 per cent of modern people suffer from a lack of sleep caused by stresses and nervous tension they regularly experience in their daily life. This phenomena is called adaptational insomnia. We tend to think about our problems at work or in our personal life all the time, get very sensitive to this kind of problems and can not sleep due to being too nervous and too much stressed out. Chronic insomnia can also be a result of stresses, as well as a result of more serious nervous conditions including depressive neurosis, mixed anxiety-depressive neurosis, and so on. Undoubtedly, as stress related load is increasing on most of modern people, stresses and depression should be considered among the major and the most dangerous lack of sleep causes, which can sometimes bring to very serious consequences and cause very serious health conditions in today’s people.

Leading too active lifestyle and getting involved into various overwhelming activities, especially before going to sleep, is another very common cause of sleep problems. We watch plenty of thrilling TV shows and horror movies, hear plenty of terrifying news, or play various computer games which have deep impact on our psychology and can cause chemical imbalanced in our brain. Those sometime result in inability to fall asleep or have a proper restful sleep every night. It is very important to control those kind of activities, especially in young children and teenagers since the effects can be really horrible. We should teach our children to follow a proper sleep routine, learn not to get focused on their problems in schools or colleges, to stop playing computer games or watching thrillers before going to sleep, as well as observe the rules of keeping their bedrooms in great shape for having a good night sleep. See some interesting tips here.

There are other less important and less common factors to play a role of lack of sleep causes that specialists are pointing at. Many people who live in big cities work shifts, and this is a key factors which causes huge sleep imbalances and inability of people to have normal rest for months and even years. In our times, as a result of globalization and internationalization, people have to travel a lot, and changing time zones has become one of quite frequent lack of sleep causes. Finally, bad ecology and terrible environment of big cities also contribute to bad health and a lack of sleep in many modern people. In order to fight against sleep problems and taking advantage of restful sleep every night, we should master some effective stress management techniques like yoga, aromatherapy, chatting with friends, or getting a new hobby. It can be good to spend more time outdoors and get involved into moderate physical activities like swimming, cycling, jogging, etc. According to the experts, drinkings sedative herbal teas (like Melissa tea or passion flower tea), having warm foot bath, or listening to some calm music before going to sleep are among the most effective remedies for insomnia.

Japanese Researchers Know How To Read Dreams

PregnancyAll of us see dreams, some if us do almost every night, and some less frequently. Dreams are an integrated part of our brain-work, and actually not seeing dreams is considered by scientists to be not a good sign. We know that our dreams should mean something, they carry some important messages and possibly can even predict our future and play a role of warning signs for some events to happen soon. That is why many people are looking for an answer to the questions who to read dreams and how to understand what dreams mean in our life. There is plenty of theories and approaches to reading dreams, and traditionally, every nation has own idea as to what one of another dream can mean for the person who’ve seen it. Besides, there are some scientific technologies being developed in order to better understand the phenomena of seeing dreams and learn how to read dreams we see at night.

Time to time, there are pretty interesting findings can be found in scientific magazines and other academic sources related to the issue of reading dreams. This way, recently the group of Japanese scientists reported that they have discovered a new approach to understanding what a person seeing in his sleep. They came up with a new idea about how to “read” dreams that other people see at night. According to the report about the study published recently in the journal Science, the experts from the ATR Computational Neuroscience Laboratories located in Kyoto, Japan, managed to use the results of MRI scans to get a key to the secrets of the dreams we see. The new technology has already got a name of “the world’s first decoding” and it works quite effectively in order to provide the humanity with the answer to the questions how to read dreams, which was a point of interest of the humanity since very old times and which made plenty of scientists in many countries of the world work on for many centuries.

For the study, the scientists from Kyoto worked with a number of participants invited for the research on analyzing their sleep and dreams. During the experiments, the Japanese researchers used the scans of magnetic resonance imaging in order to find out what exact part of human brain is responsible for dreaming and shows some activities during the sleep phase when we see dreams. Then, the participants were woken up and asked in details about what exactly they were seeing in their dreams. It was repeated for about 200 nights to every each of the participant, and the results of the MRI scans were compared to the information about actual dreams received after interviewing the participants. By the end of the experiment the scientists managed to read the dreams with about 60 per cent of precision. In other words, by using MRI scans of the participants they could predict what they were seeing in their dreams with the 60 per cent accuracy.

After that, the researchers decided to continue experiments and very soon their accuracy rates improved to 70 per cent, in the cases when the dreams that the participants were seeing were focused on 15 specific items, including men, books, or words they said. Yukiyasu Kamitani, the leader of the ATR Computational Neuroscience Laboratories study group and one of the senior researchers at the laboratories said: “We have concluded that we successfully decoded some kinds of dreams with a distinctively high success rate.” The scientists are convinced that their study and their findings should be considered only the first step on the way to findings out a successful and 100 per cent accurate technique of reading human dreams. Such kind of technologies can be extensively used in the future for studying the specific of human brain and learning new abilities of human brain which still remain unknown for us in modern times.

 

Poor Sleep Is Linked To A Higher Heart Failure Risk

Poor SleepMost of us are aware about the fact how many health risks and serious diseases are linked to poor sleep. Those who suffer from sleep disorders like insomnia or chronic insomnia. restlessness, seeing nightmares and horrors while sleeping, snoring or sleep apnea have considerably higher chances to develop chronic fatigue syndrome, depression, insufficient nutrition and weight gain, metabolic syndrome and metabolism imbalances, elevated blood pressure, brain function disorders, and even a few very common types of cancer. Plenty of studies and researches related to the issue were published recently bringing to light plenty of scientific evidence to the health risks and dangers of chronic sleep disorders and poor sleep. The findings of one more study carried out by a group of Norwegian experts appeared earlier this month in the European Heart Journal, following an extensive 11-year study of the effects of poor sleep in people’s cardiovascular health.

Researchers at the Norwegian University of Science and Technology are convinced that those people who often wake up at night and can not fall back asleep are actually at quite high risk of suffering from serious cardiovascular problems in the future. According to the published findings, interrupted and poor sleep are strictly linked to increased heart failure risk. In the framework of their study, the scientists monitored sleep patterns and health condition of over 50,000 participants aged between 20 and 89 on a long-term basis. In the beginning of the experiment, none of the participants was diagnosed with any sleep disorder and did not display any sing of insufficient or poor sleep. In addition to that, none of the participants was under the influence of other factors that could increase risks for heart failure or other serious cardiovascular condition. As it is stated in the report, none of the participants reported having such common symptoms of heart problems as feeling shortness of breath or being too exhausted.

During the study, the participants were asked to regularly report about their possible sleep problems, and those of the volunteers who started displaying the signs of various sleep disorders were monitored closer. After analyzing the data collected for 11 years, it became apparent for the scientists that those of the participants who reported disrupted sleep, inability to fall asleep when waking up at night, and other signs of poor sleep are three times more likely to develop such serious cardiovascular condition as heart failure. Even when the scientists ruled out the influence of such factors as smoking, obesity, type 2 diabetes and others, which always play a role in developing serious cardiovascular conditions, the discovered link between poor sleep quality and high heart failure risk remained. The researchers are convinced that even those people who have problems when falling asleep are also at risk for the mentioned disease.

At the same time, the scientists failed to learn about the mechanisms of the discovered link and obtain more information about the issue. “We don’t know whether insomnia truly causes heart failure. But if it does, the good thing is it is a potentially treatable condition,” said Dr Laugsand, one of the study leaders. The scientists only came up with a hypothesis that those people who suffer from poor sleep have high levels of hormones associated with stress which affect their overall health to a great extent. Many other experts underline the necessity to continue scientific work in this direction and learn more about the connections between poor sleep and elevated heart failure risk.
