00:31Why do people sleep?
00:34What is sleepiness?
00:37Sleep psychologist Masashi Yanagisawa says
00:41the answer to this mystery is to know God's work.
00:49He is also an experienced Christian.
00:54What does God say about sleep?
00:57While we are sleeping, God gives us good fortune.
01:02It is written in the Bible that we should not do bad things.
01:07It's a great word. I want all Japanese people to read it.
01:12It is true that Japanese people have the shortest sleep time in the world.
01:20What foods are good for sleep?
01:23There are not many foods that are good for sleep.
01:27I'd like to ask you about short sleepers.
01:30It's enough to sleep for an hour or 30 minutes.
01:35They are like con artists.
01:38Some people don't like to sleep.
01:4326 years ago, protein that controls awakening and sleep was discovered.
01:48Last year, he won two international awards and a Nobel Prize.
01:56TV can't ignore such a sleeper.
02:02It's not good to sleep with air conditioner on.
02:05That's right.
02:08There is a medical reason.
02:11Good night.
02:12A week with Pokemon Sleep.
02:14Now, he is studying a game app to improve his sleep habits.
02:19Let's find the sleeping face of various Pokemon.
02:23Sometimes, he goes to the country.
02:27The Ministry of Health and Welfare and the Sleep Department.
02:30What should I say?
02:33It's strange.
02:36However, the fundamental question has not been solved yet.
02:43Why do all animals sleep?
02:46What is sleep?
02:48No one can answer this question.
02:50I quote the words of Mr. Sota Fujii, who I love.
02:55He said, we can't go beyond the forest limit.
02:58We can only see the forest around us.
03:00We can't see where we should go.
03:03We can't see the peak.
03:05We can't even see how to get to the peak.
03:11The days of a researcher who has both toughness and charm are interesting.
03:18Oh, great.
03:24The base is the largest research institute in the world founded by Tsukuba University.
03:31Good morning.
03:33Good morning.
03:37Yanagisawa has been in charge of all the research facilities specialized in sleep since its founding in 2012.
03:49Each floor has a flying object.
03:53If you look closely, you can see a flying object with its eyes closed.
04:00He chose all the art on the floor and inside the building.
04:07This is my favorite.
04:10I feel like I'm raising my hand for something, but I don't know what it means.
04:16It doesn't look like a fun picture.
04:18Isn't it fun to see this?
04:22It stimulates my mind.
04:26Yanagisawa has also called in the main staff.
04:32This is the place where the symptoms are kept.
04:35This is called the yellow symptom lung.
04:38It's a very small type of lung.
04:41Do flies sleep?
04:43Yes, they do.
04:44They sleep and gradually understand the mechanism.
04:48I hope at least one of the flies is alive.
04:52It's a type of parasitic insect.
04:55The genetics of the parasitic insect are similar to that of humans.
04:59The parasitic insect has become a major research material for sleep in the past 10 years.
05:07Ants also sleep.
05:09They sleep on the floor?
05:11Yes, they sleep on the floor.
05:13When they sleep, their tentacles are bent.
05:16When their tentacles are bent and stuck to the floor, they sleep.
05:24The mouse plays a major role in the study of sleep.
05:32There are about 20,000 mice in the lab.
05:38Did you give birth to this many?
05:40Yes.
05:41That's amazing.
05:43This is about 14.
05:45The male mouse suddenly mutated its DNA.
05:49When a man made a baby with artificial insemination, the mutation was inherited.
05:54Out of the 8,000 mice that were born,
05:58a sleepy mouse was found.
06:02This is the famous sleepy mouse.
06:05There are only two of them.
06:09Currently, they are using this mouse as a clue
06:13to conduct research into the true nature of sleepiness.
06:18We are the only group in the world that studies sleep in this way.
06:26I'm saying this because I found it.
06:29I was so scared until I found it.
06:31If I couldn't find anything, how could I apologize to my wife?
06:38The researchers are given a chance to present their papers once a week.
06:43It's called a paper dojo.
06:5430% of the 310 researchers are from overseas.
06:59As the name of the dojo suggests,
07:01the presenters are subjected to harsh criticism.
07:08Most of the presenters are from Yanagisawa.
07:38You can't put your hypothesis above the data in front of you.
07:43That's Yanagisawa's saying.
08:09That's very complicated.
08:14This is my last presentation.
08:18Yanagisawa always emphasizes the details.
08:24I think he's a professional.
08:48He has a lot of work to do.
08:50He had a meeting to record a TV show online.
08:54Did my secretary give me the YouTube link?
08:58She said, please watch this.
09:01You can find the numbers on the Internet.
09:05You can find the numbers on the Internet.
09:09She's not good at all.
09:11I think she understood what I was trying to say.
09:16Don't ask me.
09:18Don't ask me what you can find on Google.
09:24He walks at a fast pace to save time.
09:28The first one is a sleeping busk.
09:31Did you watch the YouTube show I sent you?
09:37Yes, I did.
09:39It's exactly what I said.
09:42That's right.
09:43That's it.
09:44I'm sorry.
09:48What should I do when I can't sleep?
09:51I often take a deep breath.
09:54It's called a 15-minute round-trip.
09:56I recommend a 4-minute round-trip.
09:58It's exactly one minute.
10:00For a good night's sleep,
10:02take a deep breath,
10:04take a bath an hour or two before going to bed,
10:07and go to bed when you're sleepy.
10:10This is a field study using this device.
10:16Yanagisawa developed a device
10:18that allows anyone to easily record their sleep.
10:25It's important that the data is visualized.
10:31The sleep of those who complained of insomnia was actually deep.
10:36They were supposed to sleep soundly,
10:38but they were found to have insomnia when they were asleep.
10:43Knowing the quality of your sleep
10:45can lead to improving problems related to sleep.
10:53That's true. I didn't comment on anything.
10:55A young researcher was trying to summarize the paper on the subject.
11:00I think it would be interesting if it had N1.
11:03I understand.
11:04Come up.
11:06A scientific paper must be easy to understand
11:09and objective.
11:17OK.
11:19Good night.
11:22It's amazing how you can look at your data objectively.
11:33I'm very lucky to have learned how to write a good paper.
11:45There's a famous saying,
11:46publish or perish.
11:49Publish or perish.
11:51It's almost all researchers do.
11:59Yanagisawa's paper published 26 years ago
12:03was about the discovery of oleksin.
12:08He found a brain substance that decreases
12:11when you fall asleep from the brain of a rat.
12:16That protein, oleksin,
12:18was used to maintain an awakened state.
12:23There's a disease called narcolepsy.
12:31When a patient falls asleep from a sudden sleep attack,
12:35the symptoms improve when the patient injects oleksin.
12:46On the contrary,
12:48oleksin is also used to suppress sleep disorders.
12:58Can you walk on a clean road?
13:01Not at all.
13:06It takes 10 minutes by car from the lab to his home.
13:10Excuse me.
13:13Excuse me.
13:14It's like a jungle.
13:16I don't have a lighter.
13:17So, please use whatever you have around here.
13:20Is it always this bright?
13:22Yes.
13:23The reason why it's dark is because I talk a lot on a variety show.
13:29In Japan, it's too bright at night.
13:32So, it's dark at night,
13:34and it's not good for sleep.
13:38It smells like curry.
13:39It's curry rice.
13:41It's curry rice.
13:46Hiromi's wife is also a medical researcher specializing in circulatory machines.
13:54How hungry are you?
13:56I'm hungry.
13:57Are you really hungry?
13:58I'm quite hungry.
13:59Then, let's have a lot of rice.
14:08This is delicious.
14:10It's anchovy potato.
14:12Did you have any students?
14:13It's not uncommon for the theme of work to become a hot topic.
14:20What kind of research is it?
14:22It's the first time in the world that there is a causal relationship between the size of the synapse and sleep.
14:29Do you have a lot of receptors?
14:31I have a lot of receptors.
14:33Is it good for people?
14:37It's not therapeutic.
14:40It's not therapeutic,
14:42but half of the work he does is therapeutic.
14:47I do the lower part from here,
14:49and Masashi does the upper part.
14:53Circulatory system.
14:54From here to the top.
14:55From here to the top.
14:58Hiromi has been married to a student for a year.
15:03They were both baptized before the ceremony.
15:08It's interesting to talk to him.
15:12He is a geek, isn't he?
15:14He is a geek, isn't he?
15:17He doesn't talk much,
15:19but he is very...
15:21How can I say?
15:23He is very outgoing.
15:29He was born in Tokyo in 1960.
15:33His father was Dr. Lin.
15:38He got off the throne and started to play.
15:42He is a bit of a bad guy.
15:44I think he was completely diagnosed with ADHD.
15:49There were a lot of belts and reels in the store.
15:56When I started to look at them, I couldn't stop.
15:59I can't help but wonder how he got so strong.
16:06When he was a medical student at Tsukuba University,
16:09his hormone, endocerin, which increases blood pressure,
16:12was world-renowned for its discovery.
16:16At the age of 31, he went to a university in the United States.
16:19While observing a mouse,
16:21he happened to discover an orexin related to sleep.
16:27In a good way, I was free.
16:29I had almost nothing to do except for my research.
16:33I had almost nothing to do except for my research.
16:37You found an orexin because you had time.
16:40That's right.
16:42Destructive research can only be done when you are free.
16:47You are born because you are free.
16:52The biggest reason he returned to Japan
16:55was that his research on sleep was selected
16:58as one of the most advanced research programs by the Cabinet.
17:03He was able to establish a base with a huge amount of funding.
17:10There is no hierarchy between professors and students.
17:15What would you do if you were the head?
17:18I would be the best.
17:21There are many heads and teams,
17:24so it is easy to do joint research that is based on expertise.
17:30Two, three, salute!
17:33Salute!
17:38Once every two months, there is an exchange party.
17:41Yurikago is a free and unique idea.
17:44Yurikago is a free and unique idea.
17:47You are glad you came to Tsukuba, right?
17:50Yes.
17:51I was told by a young lady that I had changed a lot.
17:56I used to have wrinkles on my eyebrows.
18:05Yanagisawa has a good relationship with flat people.
18:09There was another big discovery
18:12that showed the relationship between sleep and brain.
18:17Yanagisawa is loved by the researchers here.
18:29Yanagisawa was 64 years old when he was given a surprise birthday song.
18:46The song is called,
18:49The Unpainful Things I Can't Excuse.
18:55Masashi, masashi, zen,
18:58Baba, baba,
19:02Zen, Zen.
19:09Mabi, Mabi.
19:12It's not as easy as it seems It's not as easy as it seems
19:32It's not as easy as it seems It's not as easy as it seems
19:38Congratulations!
19:44Thank you so much for very well scripted.
19:50Yeah, I really thank you so much.
20:24Congratulations!

21:39Congratulations!
21:42Congratulations!
21:45Intensification, progress, induced...
21:50Wake promoting systems.
21:52This is enough.
21:53This is enough.
21:55This is enough.
21:57Wake promoting systems.
21:58Mr. Yadagisawa is really enjoying himself at a time like this.
22:01This is enough.
22:01You know what I'm trying to say, right?
22:03Yes.
22:04That's what's important.
22:07By the way,
22:09Sleepers have a special drug for when they can't sleep.
22:14It's called Fujisota, which you can see at 1.5x speed.
22:20If you read and watch things that are beyond your understanding,
22:24will your synapses get bigger and bigger?
22:27The students of the biology department from Nada Junior High and High School have come to visit.
22:43How many hours do you sleep in a night?
22:457 to 8 hours?
22:49About half?
22:536 to 7 hours?
22:55How many hours do you sleep in a day?
22:57Less than 6 hours.
23:00That's a lot.
23:02You can't cover the amount of sleep with a good quality of sleep,
23:05so you need to make sure you have enough sleep time.
23:08It's counterproductive to force you to sleep early.
23:13There are people who are tired in the morning, right?
23:16For example, if it's foggy, you can't sleep for a long time.
23:22If you can identify the genes,
23:24and apply them to humans,
23:26you can shorten your sleep time.
23:29Yes, that's what I think.
23:32The challenge is how to compare different DNA types in a week.
23:39I think it's a very interesting disease.
23:41I don't think I can do it if I'm alive,
23:43but I think it's the future of medicine.
23:46Thank you very much.
23:48Come, come, come.
23:51The everyday life of sleep psychologist Masashi Yanagisawa
23:55is always busy.
24:02It must be to ensure a deep and rich sleep time.
24:12This program airs at 11.30 p.m., right?
24:15Yes.
24:17I'm glad you're watching the program,
24:20but please go to bed early.
24:24Don't watch TV even if you can't sleep.
24:30The next passionate continent is Erika Ikuta.
24:33She's been looking for her own path since her debut as an idol.
24:38I don't think I've caught up with my own abilities.
24:41I think it's full of challenges.
24:47Just look for me.
24:50I'm going to look for you.
24:52I'm going to look for you.
