Exercise 212. Watch the video 2.11 working in shifts.

Dr. Hamblin, I’m a police officer who works a night shift. A lot of police
departments have rotating (меняющиеся) schedules requiring (что требует)
officers to change from nights to days and back to nights again. My department
keeps us on the same shift indefinitely (неопределённое время) unless (если
только) we ask to change. Is there any research (исследование) or medical
opinion about working a rotating night-day schedule versus (в сравнении с)
working a consistent (постоянной) night shift?
Call him officer Nick. So, among people who do shift work, meaning (имеется
в виду) some day shifts, some night shifts, they have increased
(повышенные) risks of cardiovascular disease (сердечно-сосудистые
заболевания), diabetes, some cancers (некоторые виды рака), early
cognitive decline (спад умственных функций мозга). But a lot of employers
think they’re doing you a favor by saying, oh, you only need to work one week
of nights every month – in fact that might be worse for your health than doing
it bigger blocks or even staying permanently (постоянно) on nights. If you
keep yourself sleeping at a consistent (последовательный) period within that
24 hour block, you should be better off (вам от этого должно стать только
лучше) than if you’re constantly (постоянно) moving yourself around.
Basically, it comes down to (всё сводится к) the question of why do we sleep?
We all have circadian cycles (циркадные/суточные циклы) which are the
result of ambient light (рассеянного света). When it gets dark outside, your
retinal cells (клетки сетчатки) stop perceiving (воспринимать) light, your
hypothalamus (гипоталамус) senses (чувствует) that tell your pineal gland
(эпифиз) to release (вырабатывает) melatonin, and go to sleep. Then in the
morning the sun rises, wake you up by telling your pineal gland to stop
secreting (вырабатывать) melatonin and then you wake up. And these light-
dark cycles have driven us (вели нас к) to have 24 hour circadian rhythm
(ритму). So, if you’re trying to fall asleep when it’s light and wake up when
it’s dark, then you don’t get the same restorative sleep (восстановительный
сон) that your body needs to stay alive (остаться в живых). You can keep
your circadian rhythm to a 24-hour cycle artificially (искусственно) by using
black-out curtains (затемняющие шторы), by using UV
(ультрафиолетовые) lamps. So, I think this police department is great to give
you that option (вариант). The problem is obviously socially that it sucks
(ужасно) to work constant (постоянные) night shifts. The best thing would
be to move your friends and family also to a night shift cycle (цикл). I don’t
know if you can do that. You just usually have to ask. Hey, I think people who
work night shifts deserve (заслуживают) serious compensation and gratitude
