so the other speakers that we’ve heard from today are all here to talk about
from today are all here to talk about
from today are all here to talk about what turns us on
what turns us on
what turns us on I’m actually here today to talk about
I’m actually here today to talk about
I’m actually here today to talk about what turns us off so in other words what
what turns us off so in other words what
what turns us off so in other words what we do during our day and how that
we do during our day and how that
we do during our day and how that influences our ability to turn off or
influences our ability to turn off or
influences our ability to turn off or sleep at night so just quick show of
sleep at night so just quick show of
sleep at night so just quick show of hands how many people here feel tired
hands how many people here feel tired
hands how many people here feel tired right now yeah me too
right now yeah me too
right now yeah me too chances are if I’d asked that question
chances are if I’d asked that question
chances are if I’d asked that question when we first arrived this morning I may
when we first arrived this morning I may
when we first arrived this morning I may have even seen some more hands go up so
have even seen some more hands go up so
have even seen some more hands go up so when I survey my first year undergrad
when I survey my first year undergrad
when I survey my first year undergrad class at the University of Guelph more
class at the University of Guelph more
class at the University of Guelph more than 90 percent of them report feeling
than 90 percent of them report feeling
than 90 percent of them report feeling tired either some or most of the time so
tired either some or most of the time so
tired either some or most of the time so what I’m hoping to do today is to talk
what I’m hoping to do today is to talk
what I’m hoping to do today is to talk to you about why I think that is such a
to you about why I think that is such a
to you about why I think that is such a huge problem and it’s something that we
huge problem and it’s something that we
huge problem and it’s something that we really need to start doing something
really need to start doing something
really need to start doing something about so a couple of years ago in 2015
about so a couple of years ago in 2015
about so a couple of years ago in 2015 the National Sleep Foundation released
the National Sleep Foundation released
the National Sleep Foundation released updated guidelines in terms of how much
updated guidelines in terms of how much
updated guidelines in terms of how much sleep we need every single night
sleep we need every single night
sleep we need every single night based on our age so I think most of us
based on our age so I think most of us
based on our age so I think most of us in this room probably fall into the
in this room probably fall into the
in this room probably fall into the young adult or the adult range and you
young adult or the adult range and you
young adult or the adult range and you can see here in the blue that it’s
can see here in the blue that it’s
can see here in the blue that it’s recommended that we get somewhere in
recommended that we get somewhere in
recommended that we get somewhere in between 7 to 9 hours of sleep every
between 7 to 9 hours of sleep every
between 7 to 9 hours of sleep every single night for the first time and I
single night for the first time and I
single night for the first time and I think somewhat impressively they’ve also
think somewhat impressively they’ve also
think somewhat impressively they’ve also included the data in this turquoise
included the data in this turquoise
included the data in this turquoise areas and that represents the amount of
areas and that represents the amount of
areas and that represents the amount of sleep that may be appropriate so for the
sleep that may be appropriate so for the
sleep that may be appropriate so for the first time acknowledging that our
first time acknowledging that our
first time acknowledging that our individual sleep needs do vary and they
individual sleep needs do vary and they
individual sleep needs do vary and they vary based on both genetic and
vary based on both genetic and
vary based on both genetic and environmental factors but by and large
environmental factors but by and large
environmental factors but by and large we need 7 to 9 hours of sleep every
we need 7 to 9 hours of sleep every
we need 7 to 9 hours of sleep every single night so those are sleep
single night so those are sleep
single night so those are sleep requirements how do they compare with
requirements how do they compare with
requirements how do they compare with our sleep realities well we see pretty
our sleep realities well we see pretty
our sleep realities well we see pretty quickly that they don’t line up so this
quickly that they don’t line up so this
quickly that they don’t line up so this is data from 2012 showing that almost
is data from 2012 showing that almost
is data from 2012 showing that almost 50% of the adult population is getting
50% of the adult population is getting
50% of the adult population is getting less than 7 hours of sleep every night
less than 7 hours of sleep every night
less than 7 hours of sleep every night so that means almost half of all adults
so that means almost half of all adults
so that means almost half of all adults are sleep-deprived
are sleep-deprived
are sleep-deprived so how did we get here how did we as a
