Sleep Apnea Negative Effects

What would happen if you didnt sleep Claudia Aguirre

In 1965, 17yearold high school student,Randy Gardner stayed award for 264 hours. That's 11 days to see howhe'd cope without sleep. On the second day, his eyes stopped focusing. Next, he lost the abilityto identify objects by touch. By day three, Gardner was moodyand uncoordinated. At the end of the experiment,he was struggling to concentrate, had trouble with shortterm memory,

became paranoid, and started hallucinating. Although Gardner recovered withoutlongterm psychological or physical damage, for others, losing shuteye can resultin hormonal imbalance, illness, and, in extreme cases, death. We're only beginning to understandwhy we sleep to begin with,

but we do know it's essential. Adults need seven to eight hoursof sleep a night, and adolescents need about ten. We grow sleepy due to signalsfrom our body telling our brain we are tired, and signals from the environmenttelling us it's dark outside. The rise in sleepinducing chemicals, like adenosine and melatonin,

send us into a light doze that grows deeper, making our breathing and heart rate slow down and our muscles relax. This nonREM sleep is when DNA is repaired and our bodies replenish themselvesfor the day ahead. In the United States, it's estimated that 30% of adultsand 66% of adolescents are regularly sleepdeprived.

This isn't just a minor inconvenience. Staying awake can cause serious bodily harm. When we lose sleep, learning, memory, mood, and reaction time are affected. Sleeplessness may also cause inflammation,

halluciations, high blood pressure, and it's even been linkedto diabetes and obesity. In 2014, a devoted soccer fan died after staying awake for 48 hours to watch the World Cup. While his untimely death was due to a stroke, studies show that chronically sleepingfewer than six hours a night increases stroke risk by four and half times

Beyond the Data Preventing Adverse Health Effects from Nanotechnology

Iskander: I'm John Iskander,welcome to CDC Beyond the Data. In association withtoday's encore presentation on Nano technology forPublic Health Grand Rounds, we're very pleased to have Paul Schulte joining us from CDC's National Institute for OccupationalSafety and Health. Paul could you reorientour audience a little bit to Nano technology as Nanotechnology has now moved

from science fiction verymuch into the real world. When we say Nano technology howsmall is small and what kind of industries arewe talking abouté Schulte: Well, onenanometer is the size of ten hydrogen atoms,put side by side. So you get the ideathat we're talking about something that'sextremely small. Something that's generally onlyvisible by electron microscopes.

So, ten hydrogen atoms side byside would be one nanometer. If you recall from thepresentation that I did, as you cut matter down fromlarge pieces to small pieces, when you get downaround sixty nanometers, you start to see newscientific properties. Things are more conductive,they're more magnetic, they're stronger, they're morereactive and you can do a lot of things with that,you can make a lot

of different products. And so Nano technology reallypervades almost all industrial sectors, and essentially,Nano materials will be in almost every kind ofproduct that's manufactured in the future. Right now we see Nano materialsin automobile side panels, we see them in clothes, wesee them in concrete, in food, in every differentkind of electronics

that you can think of. So there's a wide rangeof uses of Nano materials and they're also used inmedicine as possible ways of reaching target,target cells, specifically without hurting thesurrounding area. Iskander: So, very much a partof everyday life and moving into more, almost sciencefiction like applications, and I think you did avery good job of talking

about why we mightwant to use some of these materials,some of the benefits. But, I understand thereare also concerns for some of the workers exposedto these materials. Can you tell me a littlebit about what we've learned about that and maybe some ofwhat we still have to learné Schulte: Well, we're about tenyears into the commercialization of Nano technologies, so, for,in the 90's there was a lot

The Causes and Effects of Obstructive Sleep Apnea

hi everyone thanks for tuning into eZeliving you know in a previous webisode we did a story about snoring and how it can lead to sleep apnea and it got me thinking well maybe just maybe I have sleep apnea because i'm experiencing the symptomsshortness of breath,800:00:28,460 gt; 00:00:31,109snoring.and when i wake up i feel really really tired

and you know what, they got me thinking maybe i should investigate and do someresearch on this subject matter to find out what sleep apnea is so let's take this journey togetherand hit the internet so here we are I'm gonna head to the computer lounge and do some research well this is interesting

sleep apnea if undetected could lead toa heart attack heart failure stroke even type2 diabetes so here's a piece of information that ithink is important for you to you know did you know that 4% of the world'spopulation is affected by sleep apneaé and we all know that car accidents is oneof the leading cause of death worldwide of which, 1520%are sleep related

it's shocking! so i've had a chance to go through theresearch on the web we've taken a look at WebMD and some slideshows that talks about and describes whatsleep apnea is all about but I found this really really nice tutorial on the web that i think it's important to share with you

when most people are asleep air flows freely through the upper airways into the lungs giving a stable level of oxygen in the blood stream in individuals with obstructive sleep apnea(OSA)the tongue and soft tissue in the airway relax during sleep as the tongue and tissue partiallyobstruct the upper airway it causes loud snoring. when the tongue and tissuetotally obstruct the airway it causes an apnea and breathing stops. the chestcontinues to move as the person tries to breath. but the blockage prevents freshair from reaching the lungs

the oxygen content in the blood goesdown and apnea may last anywhere 10 to 60seconds before the brain recognizes that there's a problem the brain briefly arouses the body fromsleep just enough to open the airway the person with OSA can observesnorting, gasping and choking for breath as the airway opens an air flows backinto the lungs woow, the information is overwhelming and it's safe to say that i do havesleep apnea
