how does sleep affect metabolic health
00:03
so the global health cost of diabetes is
00:06
375 billion a year
00:08
we now know that good metabolic health
00:10
and lower risk of diabetes is tied into
00:13
getting good sleep
00:14
several large epidemiological studies
00:16
spanning several continents have shown
00:19
that there are far higher rates of type
00:21
2 diabetes amongst people that report
00:23
sleeping less than 6 hours a night on a
00:25
regular basis
00:26
and that association remains significant
00:29
even after taking into account
00:31
all the other contributing factors such
00:33
as body weight
00:34
alcohol consumption smoking age
00:37
gender and race initially it wasn't
00:40
clear
00:41
whether it was diabetes that impairs
00:44
your sleep
00:45
or potentially that it's sleep impairing
00:47
your body's ability to regulate blood
00:49
sugar
00:50
and thus causing diabetes but now
00:52
studies have shown that it's definitely
00:54
the direction
00:56
of the relationship comes from sleep to
00:59
diabetes
01:00
it seems that when we get limited sleep
01:03
we're around 40 percent less effective
01:05
at absorbing glucose
01:07
compared to when we get a full night's
01:09
sleep
01:10
so the conclusion is that poor sleep
01:12
seems to impair the body's ability to
01:14
absorb glucose from the blood
01:17
leading to high blood sugar in a
01:19
pre-diabetic state
