Not getting enough rest can make a person more prone to infection, obesity, heart disease and a myriad of other serious health problems. With this in mind, how much sleep would you say you get per night? You may be able to wake up and get going after five or six hours, but is that enough? The recommended amount for a healthy adult is between seven to nine hours per night and its not just about the number of hours you get, but the quality of your sleep as well, if youve ever been jet lagged. You know all too well that departures from a sleep schedule can have some ill effects. This is because the human body follows a 24 hour, circadian rhythm or circadian cycle that can be thought of as your internal clock. It regulates when youre awake or asleep and helps your body coordinate when to carry out different internal functions. Circadian rhythms have become part of medicine in that, when one is thinking about what is your blood pressure high? When is your ability to sleep, its all regulated by a circadian clock system that is throughout the entire body thats dr fred turek, a professor of biology at northwestern university and the director of their center for sleep and circadian biology? Turek says your circadian rhythm is vital to a variety of bodily functions and throwing off this internal clock has several negative effects. People who are working during the night time say from midnight to 8 a.
m and then trying to sleep during the day have a much higher prevalence of variety of mental and physical disorder. But what weve learned over the years is that any sort of disruption of our biological clock at the level of the whole organism, meaning all of our biological rhythms or even at the level of a single tissue or organ such as the pancreas, its not properly timed. With all the rest of the circadian clocks in the body, then we can have a dysfunction of that particular organ or that particular tissue for astronauts in space who dont have sunrise and sunset keeping their internal clocks accurate. This can pose some serious health challenges. Nasa has been very interested and aware of this circadian issues, disrupting strategic rhythms, disrupting sleep and theyve responded very over the years, such that the astronauts, for example, are given eight hours of time to sleep and theyre, roughly awake about 16 hours and theyre on a very Fixed light dark cycle even in space, even though theyre going around the earth every 90 minutes, and so their day night cycle is a 90 minute cycle, but the for example, the international space station, but even on the shuttle, the light dark cycle is controlled and its Maintained constantly theyre not shift workers in the general sense of the term, because nasa makes sure that they sleep at the same time and are awake at the same time unless theres some sort of event that needs to disrupt their sleep weight cycle.
Nasa scientists report that, on average across missions astronauts in space get about six hours of slumber per night. You may think that this number isnt that bad, but the quality of sleep is typically lower than on earth. According to dr emmanuel, urkita urkita is the chief medical officer at the translational research institute for space health, a key partner of nasa hes, also an assistant professor at the center for space medicine at the baylor college of medicine. He says that the rapid eye movement phase, the deepest stage of sleep, is drastically reduced, while in space its during that phase that you get most of the sleep that you know brings all of the benefits from sleeping. So, even though you might have six hours of sleep, the face of sleep, that gives you most of the benefits and gives you the mental refresh is reduced by 50. In addition to this deficit, urikita says that roughly 70 percent of astronauts onboard space shuttles and at the international space station have needed sleeping pills to help fall or stay asleep along with medications. There are set protocols and routines in place to help signal the body that its time to rest or wake up. Usually they get waking up with some music that they play from earth. The days try to be roughly 16 hours of work and a lot of activities. I would say work with 16 hours of scheduled activities and eight hours of sleep, but you know the space station is not the ideal place to sleep, usually at least on the usos on the u.
s segment. Each astronaut has his or her own living quarter its. You know a small place, they can interact with doors, they can have some privacy there. Some of them have some windows to look out outside tiny windows like portholes, and you know they have some other personal items there some family pictures they have a computer, so they can get some privacy there. But that being said, its still not an ideal place to sleep. Spacecraft can be a noisy setting with all of the fans and systems running 24 7.. In addition to blocking out the white noise, astronauts have to get used to the peculiar feeling of sleeping without gravity. Instead of lying back on a firm mattress, topped with lush pillows, they get their rest while floating around in a sleeping bag tethered to a wall. The sleeping bag is really on the wall or the floor, or the ceiling depends on what part of the station they are. Of course, they dont feel that they are on the sleeping on that on the ceiling or sleeping on the wall, because theres no gravity right. So theres no sensory, motor or proprioception cues, but you know its not what youre used to right, youre used to sleeping on your side, your front or your back, but not sleeping, technically standing up right, so thats. Another thing that theyre, not the proprioception cues that you normally get here on earth when youre sleeping theyre, not there in space, despite the hardships that arise from this lack of sleep or ketu, says that in the short term, the comprehensive training and screening that astronauts undergo On earth help prepare them to still perform, even if they feel sleep deprived.
Nasa is also developing new technologies to help aid sleep, including the development of a headpiece, that astronauts could one day wear as they prepare for bed. Imagine these sort of helmets that you would be wearing or headbands and they have the resonating at a very specific frequency. So this frequency goes into your brain and then it helps you to number one to go to sleep, a number two to stay sleeping right and this is completely non pharmacological. So you know all the medications that i was mentioning earlier and not only these ones, but any medication that exists in the world. It has potential adverse events right and secondary effects. Turek says that theres still much research. That needs to be done to understand the long term ramifications of living and sleeping in space. We only have really good data for one person, really scott kelly. I think who has been in space for a year, and you know to get to mars and back its going to be about a three year mission and nasa continues to study. What is the effect of longer and longer time spent in space on the human biology, including the sleep, wake cycle, and we want to keep collecting data, and you know, since the mission of mars is probably going to be in the 2030s nasa and we ill call It nasa will be continuing to monitor the microbiota, the circadian rhythms, the sleek, wake cycle of individuals who are in space for long periods of time.
We do know that sleep is vital to each and every human, whether youre hitting the pillow while on earth or in space.

Im gary price, cardiovascular or cv disease is the number one killer of adults in the u.s and millions of people trying to reduce their risk of a heart attack or stroke may unknowingly, be taking medications that are not proven nor fda approved to reduce cardiovascular risk. Lets hear from cardiologist dr john osborne. Many people are unaware that, after a failed outcome, study the fda revoked the approval of pheno fibrates when added to statins, as the risk outweighed the benefits to heart health. Its important to remember that statins, along with diet and exercise, can lower cardiovascular risk by about 25 to 35 percent, but persistent cardiovascular risk, which can lead to a life threatening event, may remain. I would tell anyone still being prescribed phenotype rates such as tri, core and trilipics, with a statin to talk to their doctor about fda, approved therapies, for cardiovascular risk reduction, to learn more and get clear on the facts visit its clear to me now: dot com again, Thats its clear to me now: dot com, chuck e cheese needs you theyre hiring 3 500 employees nationwide to welcome families to its upcoming season of fun as they work today get paid tomorrow.

For a complete listing of open positions, new studies show for the first time that reducing air pollution may roll back. The risk of dementia research reported at the alzheimers association international conference 2021 shows a clear connection between air quality and physical brain changes, defining alzheimers disease whats. More reducing fine particulate matter in the air is associated with slower cognitive decline and a 20 reduction in dementia risk. Claire sexton is director of scientific programs and outreach at the alzheimers association. Whats exciting is were now seeing data showing that improving air quality may actually reduce the risk of dementia. Air pollution is bad for our brains and our overall health. This demonstrates the importance of policies and action by both governments and businesses that address air pollution.
Studies were conducted in large populations in the us and france sexton says the findings are especially important in urban areas, where higher levels of air pollution are common, find out more at alz.org and thats viewpoints.
