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

Today I'm going to talk about sleep. We humans spend almost 30% of life in sleeping. Sleep is important to refresh your body, reorganize your memories, and insufficient sleep may lead to daytime sleepiness and lack of concentration on your work. And too much insufficient sleep may leave your immune system weaker, and you can catch a cold easily. If you look at the market, there are so many sleeprelated goods,
like comfortable pillows, futons, some sleepinducing music CDs, and more recently, there are some hightech sleep monitors available. And if you check your smartphone mobile apps, there are so many sleeprelated applications on the smartphone apps market. And usually these sleeprelated appsare given a top 10 ranking in the healthcare categories. Demand for comfortable and better sleep is getting larger and larger.
But, by the way, my specialty is not sleep. I am a parttime orthopedic surgeon treating bones and joints, not cosmetic surgery, by the way. But mostly, I dedicate my work to regenerative medicine to try to make organs from cells, instead of using other peoples' organs for transplantation. And we're also developing a robotic system cooperating with companiesfor cell cultures,
and also we're developinga kind of 3D bioprinter. With this printing system, we can fabricate living 3dimensional construct from cells. So, our future goal is to make patients' own organs from patients' own cells. And to expand my research eyes, I really love to explore many gadgetsand new technologies, such as quad copter or some activity logger and work out. I couldn't finish this program, but already I'm thinking about
whether these technologies can be applied to our research field. And recently, I was really amazed by Kinect. It's a kind of 3D scanner and motion sensor, relatively inexpensive, plus, it's released as a game controller from Microsoft but recently thanks to many hackers and Microsoft, many programmers can programtheir own Kinect program. So, one day, I investedin Kinect with my kids. I noticed this Kinect can be used as night vision.
Even in the darkness, the systemis still tracking your body parts and captures the night image without turning the light on. So I had the idea to use Kinect as a sleep monitor. Because most of the smartphone sleep apps cannot capture your sleeping image, only replay your sleeping sounds and some graphs from motion sensors. I put my Kinect in my bedroom like this, and made software as a night recorder. And even covered with a futon, the system still tracks your body,
