William Dement, a renowned sleep researcher at Stanford University, is quoted as saying that after 50 years of study, the only reason he can think of for why we sleep is "because we become sleepy." Sleep certainly matters for our health and wellbeing even though it may be, as one researcher put it, "the sole major habit in quest of a function." Do we, however, have it right? What do studies on sleeping positions say? Is there a proper sleeping position? The majority of people favor sleeping on their side. This is encouraging news because people who sleep on their backs are more likely to have trouble falling asleep or breathing during the night. Most of the time, we have a tendency to shift around quite a bit at night. According to a study involving 664 sleepers, on average, participants slept on their side 54% of the time, their back 37% of the time, and their front 7% of the time. Males are more likely to change positions throughout the night and move their arms, ...

Recent studies show that mental illness significantly increases the risk of dementia and other cognitive deficits. Insomnia in older persons increases their risk of memory loss and long-term cognitive impairment, including dementia, according to recent Canadian research. Over 26,000 participants in the Canadian Longitudinal Study on Aging, ranging in age from 45 to 85, provided data for the study, which was published in the journal SLEEP. The researchers contrasted neuropsychological testing in various cognitive areas from 2019 and a follow-up in 2022 with completed self-reported sleep and memory assessments. Those who claimed their sleep had gotten poorer over the course of those three years were more likely to report subjective memory decline. "Adequately managing insomnia condition might become an important preventive tool for cognitive deterioration," write Jean-Louis Zhao and Nathan Cross. Thanks to Nathan Cross According to co-lead author Nathan Cross, a postdoctoral fe...

Although the majority of us view nightmares as mostly benign, they may actually be a warning. People who frequently have awful dreams in middle age are more likely to develop dementia later in life, according to study from the University of Birmingham. According to recent studies, dreams may become widespread years or even decades before dementia's typical memory and reasoning issues manifest. Today, September 21, 2022, the study will be released in The Lancet publication, eClinicalMedicine.                                                                                                  According to Dr. Abidemi Otaiku of the University of Birmingham's Center for Human Brain Health, "We've shown for the first time that upsetting dreams, or nightma...

On the warmest summer days, you could find yourself nodding off in the midst of the day. In several regions of the world, it's usual to schedule "siestas" and close businesses at the warmest times of the day. In actuality, biology rather than just society might be to blame for this. Temperature has an overall impact on human behavior, including eating, activity levels, and sleep-wake cycles. We can have problems going asleep in the summer, and we might take longer to wake up in the winter. However, little is known about the connection between sensory neurons and the neurons that regulate this cycle. Northwestern University neurobiologists have found some clues as to what is occurring. Fruit flies are physically predisposed to taking naps in the middle of the day, according to a recent study that was just published in Current Biology. A comparable "thermometer" circuit for hot temperatures is investigated in the current work, which is a follow-up to their 2020 Bi...

Teenagers who sleep for fewer than eight hours each night are more likely to be overweight or obese. Teenagers who sleep for fewer than eight hours each night are more likely to be overweight or obese than their classmates who obtain the recommended amount of sleep, according to a study presented at the European Society of Cardiology (ESC) Congress 2022. A combination of other harmful traits, such as excessive belly obesity, high blood pressure, and abnormal blood lipid and glucose levels, were also more prevalent in shorter sleepers. According to the study's author, Mr. Jess Martnez Gómez, a researcher in training at the Cardiovascular Health and Imaging Laboratory of the Spanish National Centre for Cardiovascular Research (CNIC), Madrid, Spain, "our study shows that most teenagers do not get enough sleep and that this is connected with excess weight and characteristics that promote weight gain, potentially setting them up for future problems." We are currently looking a...

A significant study that was presented on September 5 at the European Respiratory Society (ERS) International Congress in Barcelona, Spain, found that people with obstructive sleep apnea (OSA) have a higher chance of developing cancer. [1] Loud snoring is a common sign of obstructive sleep apnea, while not everyone who snores has the disorder. A second study discovered a connection between OSA and a loss in cognitive abilities in the elderly. Some cognitive tests revealed a greater deterioration in men and those 74 years of age or older. According to a third study, patients with more severe OSA were more likely to experience blood clots in their veins, a condition that could be fatal. People with OSA frequently experience partial or total obstruction of their upper airway while they sleep, which results in frequent breathing pauses. This frequently leads to daytime lethargy, loud snoring, gasping, and choking. OSA is thought to affect between 7 and 13 percent of people. The disorder is...

A stress transmitter, according to recent research, wakes your brain more than 100 times each night. when you come to. The alarm is set for 02:56. Oh no, it's not time to wake up yet, you think, fearing that the next day you'll need a lot of coffee to stay awake. Most individuals think that uninterrupted sleep is necessary for getting a good night's rest. Therefore, waking up in the middle of the night when all you want to do is sleep can be really frustrating. Noradrenaline, a stress hormone, has been linked to frequent midnight awakenings, according to a recent study from the University of Copenhagen. But don't be concerned. All of these things help you have a regular, peaceful night's sleep, and they may even be indicators that you slept well. "You may think of sleep as an ongoing state from which you arise. But sleep is more difficult than it would seem. We've discovered that adrenaline causes you to wake up more than 100 times a night. A member of the ...

Darkness in the Thoughts Concept of Dream Nightmare According to a study, having frequent nightmares may be an early sign of Parkinson's disease. Researchers at the University of Birmingham believe that older persons who start to have nightmares or unsettling dreams may be exhibiting the early signs of Parkinson's disease. Recent research that was published in the journal eClinicalMedicine found that those who frequently experienced nightmares were twice as likely to eventually receive a Parkinson's diagnosis as those who did not. The study involved a cohort of elderly males. The prospect of using nightmares as a risk factor for Parkinson's has not been investigated, despite previous studies showing that persons with Parkinson's disease had more nightmares and unsettling dreams than adults in the general population. "Although it can be incredibly helpful to diagnose Parkinson's disease early, there are very few risk factors, and many of these need expensive...

According to a new study that was presented at SLEEP 2022, those who snore frequently and those who are at at risk of developing obstructive sleep apnea are less active than those who don't. In three years' worth of data from the National Health and Nutrition Examination Survey, researchers looked at the relationship between snoring frequency and minutes of sedentary activity. Based on participant reports of snoring frequency and amount of sedentary activity, researchers developed a score to identify people at risk of sleep apnea. Individuals who often snore had around 36 more inactive minutes per day than those who reported they never snored, even after adjusting for characteristics including gender, age, race, education, and marital status. Additionally, those with a high risk of developing sleep apnea were idle for around 44 minutes longer each day. According to lead author Dr. Michael Grandner, head of the Sleep and Health Research Program at the University of Arizona, ...
