Going to bed whenever you feel like it.
But there are many nights and days with little or no sleep at all because of the concerts.
This concert in São Paulo, Tico threw himself in the crowd.
- After that outburst of energy, I’m ok.
- Very well, thank God.
- It feels like I just woke up.
- Where’s the earing? They stole it.
- They stole it? They didn’t steal it, they took it.
- No earings, no shoes ...
- The watch is here.
- Aha! The actigraph survived!
... And it registered the Tico’s wakefulness and sleep cycle for another six days on the road.
Now Tico gives the sleep institute’s researchers the actigraph.
They take down the data onto the computer,
and they will analyze how much the musician has slept in the past ten days
- Here is night time,
so there are small movements during the night, ok?
- Here is the person’s day time.
Even the researcher is astoned.
- Gosh, this guy doesn’t sleep!
Each line on this chart shows a day in the life of Tico Santa Cruz
The moments of sleep and times he drops off aren’t many in relation to the periods of activity.
On these first days, for example, Tico practically didn’t sleep.
A normal person,
who sleeps and wakes up everyday at the same time,
would show this type of chart.
- See how you do your sleep on the next day …
when you delay the start of it
- Yeah ...
- It gets shorter.
- On the other day you were a little bit later and your sleep got even shorter.
- Yeah. Even more on the following day.
- I think you need to sleep a bit...
- If he loses too much of this information that belongs to his biological clock,
- the time to sleep and wake up,
- he could, in a few years start with having insomnia.
- I need to sleep!
Yeah Tico, you need to sleep a bit more.
They cannot drop off.
How does the flight controller and bus driver fight against drowsiness?
In awhile
500 flights a day.
here, at the international airport of Cumbica, in São Paulo,
there is always a plane landing
another that sets off,
and many in the air.
24 hours without interruption.
All monitored from the tower control
Errors cannot be made here
A failure can cause a disaster.
Myron José Coelho has been doing this for the past 20 years
and he knows that.
Yesterday, he worked during the day,
and the day before yesterday he worked in the afternoon,
and today he started at midnight
and will go on until six in the morning.
- I get off work in the morning, at 6am.
- I worked all through the night shift.
- When I get off, I don't sleep during this period
- so I may be able to sleep only during the night,
- so I don’t change the day for night
- Do you sleep well?
- I do. I sleep fairly well, actually.
- In the periods which I can rest, I sleep really well.
But not everyone can be adapted so easily to shift jobs
This happens because it's the biological clock that exists inside each one of us
that determines which is the best hour to sleep and wake up.
- If you find vespertine people who like to work during night time,
- and were able to put these people working during the night shift,
- and the matutinal, those who like day time, working only during the day
- you would have much better productivity
- and these people would have better life quality,
- and they would be able to perform so much more adequately
- than they have been performing with this variation of work during shifts.
In Myron’s case, mastering his sleep is a matter of life and death.
- It’s a very stressing job. It deals with lives.
- When dealing with lives, the margin of error is zero.
- The hit has to always be 100%.
The lack of sleep is one of the largest causes of death on Brazilian roads
On this one, on March 5th, 2002,
a car taking three police officers was returning from an investigation,
when suddenly the car crossed the road
and collided with a truck coming in the opposite direction
This twisted carcass is what’s left of the car.
The Driver Gilmar Guimarães died right away.
Oswaldo Costa, who was in the passenger’s seat,
lost a piece of his ear and had light wounds.
- How about here in front, Oswaldo?
- The front part here, Guimarães was all ground up.
- Did you see it? Do you remember?
- I do.
- How about during the drive, did you notice that at sometimes he seemed to be absent?
- We would sometimes talk to him and insist on it
- and he always would say “No, I’m thinking about something else”, and so.
- We didn’t realize he was dropping off.
It is believed that the driver fell asleep behind the wheel after a heavy lunch meal.
- Guimaraes used to eat a lot.
- When we ate in restaurants, because we always ate out,
- we were on the road,
- he would really eat a lot.
- Did he appear to be tired?
- He appeared to be a bit tired, as we all were.
- There's a bad eating error which is extremely frequent.
- Brazil is extremely rich in highway steak houses
- we have the stimulation to eat heavy food.
Doctor Sergio Barros Vieira, sleep specialist, says that
20% of the accidents on the roads occur between 3 and 7 pm
exactly after lunchtime
period when the body naturally feels drowsiness
due to the decrease in the body temperature.
Dr. Sergio created a Sleep Medicine Program,
pioneer and patented by a bus company.
João Alexandre is going to drive for 10 hours this evening,
from Rio to Vitoria city.
Before leaving the company,
he is subjected to a test
that evaluates his capacity to react to stimulus
João completes the test in 18 seconds
- Above 30 and below 10 he would not travel,
- and would be conducted to the Sleep Medicine Program to be better evaluated.
