A listener production.

00:00:13.080 --> 00:00:16.120
Hi, Welcome to Crappy to Happy with Tip and Cass.
3
00:00:16.399 --> 00:00:19.600
Thanks for joining us in this series. We take you
4
00:00:19.679 --> 00:00:23.160
through tips and tools to help you feel less crappy
5
00:00:23.839 --> 00:00:26.920
and much more happy. Last episode we were talking about
6
00:00:26.960 --> 00:00:31.280
emotional eating. This episode, we're going to talk about giving
7
00:00:31.359 --> 00:00:35.479
it arrest. The importance of sleep. This is a huge topic,
8
00:00:35.560 --> 00:00:36.920
isn't it. Cast This is.
9
00:00:36.960 --> 00:00:40.000
Probably one of my most favorite topics ever. Mind you,
10
00:00:40.200 --> 00:00:44.280
I'm a massive sleep evangelist, and I think that we,
11
00:00:44.399 --> 00:00:47.000
or well I know that a lot of people really
12
00:00:47.359 --> 00:00:50.960
really significantly underestimate the importance of sleep for mood and
13
00:00:51.000 --> 00:00:52.439
for health and for all sorts of things which we
14
00:00:52.479 --> 00:00:53.079
will talk about.
15
00:00:53.359 --> 00:00:55.759
How does it make you feel crappy not getting enough sleep?
16
00:00:56.000 --> 00:00:59.119
Wow, that's actually a good question. And we all know
17
00:00:59.200 --> 00:01:01.920
that after just one night, for example, of not getting
18
00:01:02.039 --> 00:01:05.680
enough sleep, that we can feel tired, irritable, and cranky.
19
00:01:05.840 --> 00:01:09.159
And you know it can affect your mood. You know,
20
00:01:09.200 --> 00:01:11.159
you might get tearful, you know, if you've had a
21
00:01:11.159 --> 00:01:13.280
few nights of yeah.
22
00:01:14.680 --> 00:01:16.680
I'm sorry, I don't know where that came from.
23
00:01:17.280 --> 00:01:19.680
When you've had a not enough sleep while because of
24
00:01:19.719 --> 00:01:22.519
pregnancy or your children or whatever, absolutely the thing is
25
00:01:22.519 --> 00:01:26.480
from a psychological perspective, we have always known that sleep
26
00:01:27.680 --> 00:01:31.120
problems are a symptom of mood disorders. So, for example,
27
00:01:31.120 --> 00:01:33.159
when I talk to people and I'm assessing them for
28
00:01:33.239 --> 00:01:35.599
anxiety or depression, one of the questions that we ask
29
00:01:36.239 --> 00:01:38.159
is do you have trouble falling asleep? And do you
30
00:01:38.200 --> 00:01:40.719
have trouble staying asleep? That, like binging awake at two
31
00:01:40.760 --> 00:01:43.959
in the morning, is very symptomatic of mood disorders to
32
00:01:44.000 --> 00:01:46.760
people who are depressed, for example, or are you getting
33
00:01:46.760 --> 00:01:48.920
a lot of sleep but still waking up feeling tired
34
00:01:49.200 --> 00:01:52.879
and not rested. So we've known that sleep problems are
35
00:01:52.920 --> 00:01:56.280
a symptom, but what we know now is that actually
36
00:01:56.319 --> 00:01:58.959
not getting enough sleep or having sleep problems is also
37
00:01:59.000 --> 00:02:03.040
a cause of mood disorders. So if you're chronically sleep deprived,
38
00:02:03.040 --> 00:02:07.560
it can actually lead to anxiety, depression and other issues
39
00:02:07.599 --> 00:02:09.360
like that. So it actually tends to become a really
40
00:02:09.479 --> 00:02:13.560
self reinforcing, like a self perpetuating kind of a cycle,
41
00:02:14.000 --> 00:02:16.199
and a lot of people, again, like when you talk
42
00:02:16.240 --> 00:02:19.639
to people, they don't realize just how important it is
43
00:02:19.680 --> 00:02:23.319
to tackle that sleep issue straight away, to try to
44
00:02:23.360 --> 00:02:28.680
get that sleep, you know, more balanced and you know,
45
00:02:28.879 --> 00:02:29.840
more regular So.
46
00:02:29.879 --> 00:02:32.319
In your practice you are assessing people's sleep when they
47
00:02:32.360 --> 00:02:34.039
come to you and they're, yeah, well I'm not a
48
00:02:34.080 --> 00:02:36.680
sleep doctor, it certainly comes into it.
49
00:02:36.680 --> 00:02:41.199
It's absolutely it's a listed symptom. Wow for you know, depression.
50
00:02:41.680 --> 00:02:45.840
And with that, can it actually affect your brain and
51
00:02:45.919 --> 00:02:49.479
how you think during the day and your cognitive performance?
52
00:02:49.800 --> 00:02:53.639
Like this is fascinating too. So during sleep, your experiences
53
00:02:53.919 --> 00:02:56.039
are laid down into long term memory, so your memory
54
00:02:56.120 --> 00:02:58.759
is formed while you sleep, so you can have problems
55
00:02:58.800 --> 00:03:01.520
with memory if you're not getting enough sleep. You also
56
00:03:01.639 --> 00:03:06.639
experience you know, decline in things like focus and decision making.
57
00:03:07.280 --> 00:03:08.960
You know, we sort of get that. You sort of
58
00:03:09.000 --> 00:03:10.919
know if you're not getting enough sleep. What I would
59
00:03:10.919 --> 00:03:13.240
say is, we know a lot of people. You hear
60
00:03:13.240 --> 00:03:15.479
people say, oh I get by on five hours sleep,
61
00:03:15.560 --> 00:03:17.479
or you know, sleeps for the week, or you can
62
00:03:17.520 --> 00:03:20.360
sleep when you're dead. If you were to put those
63
00:03:20.400 --> 00:03:22.639
people we have done. You know, you put people through
64
00:03:22.759 --> 00:03:26.800
a range of cognitive tests and they perform poorly on
65
00:03:26.879 --> 00:03:30.159
every single aspect of cognitive performance, like they just do not.
66
00:03:30.199 --> 00:03:33.080
They might think they're functioning, but they are absolutely not functioning.
67
00:03:33.080 --> 00:03:36.080
There is a tiny, tiny percentage of the general population
68
00:03:36.680 --> 00:03:39.439
who can get by on, you know, less than five
69
00:03:39.479 --> 00:03:43.159
hours of sleep. I wish I could remember the stat
70
00:03:43.159 --> 00:03:45.360
It's like four percent or something of the general population.
71
00:03:45.400 --> 00:03:49.400
It's a tiny number, so it does affect cognitive performance.
72
00:03:49.919 --> 00:03:54.680
So studies now show that seventeen hours of no sleep
73
00:03:55.240 --> 00:03:58.759
is the equivalent to having a blood alcohol reading of
74
00:03:58.919 --> 00:04:02.599
point oh five. So here in Australia, a point oh
75
00:04:02.680 --> 00:04:05.879
five is our is the limit for drink driving.
76
00:04:05.919 --> 00:04:07.000
You're little bit drunk, don't you?
77
00:04:07.039 --> 00:04:09.520
When you're to keep that in perspective, if you get
78
00:04:09.599 --> 00:04:11.680
up at seven in the morning, go to work all day,
79
00:04:12.240 --> 00:04:16.000
go out at night, even without having anything alcoholic to drink,
80
00:04:16.560 --> 00:04:19.959
by midnight, you're essentially at the equivalent of point oh five.
81
00:04:20.279 --> 00:04:20.759
So scary.
82
00:04:20.759 --> 00:04:24.120
For seventeen hours of no sleep twenty four hours, it
83
00:04:24.160 --> 00:04:27.439
increases two point one. So if you think about people
84
00:04:27.879 --> 00:04:31.319
we truck drivers for example, not that I want to
85
00:04:31.360 --> 00:04:34.839
gang up on truck drivers, but drowsy driving is as
86
00:04:34.839 --> 00:04:36.839
bad as drunk driving, it really is.
87
00:04:37.079 --> 00:04:39.199
And there'd be some moms out there who work all
88
00:04:39.279 --> 00:04:41.560
day and come home and have a sick child and
89
00:04:41.600 --> 00:04:42.680
they're up all night, and.
90
00:04:42.680 --> 00:04:45.759
Oh yeah, there's plenty of people out on the roads
91
00:04:45.759 --> 00:04:49.199
every day who wouldn't realize how dangerous that is. The
92
00:04:49.279 --> 00:04:55.240
drowsy driving thing causes millions of you know, millions thousands
93
00:04:55.240 --> 00:04:56.120
of accidents.
94
00:04:57.160 --> 00:05:00.279
Yeah, so sleep can really affect your brain. Can it
95
00:05:01.079 --> 00:05:03.279
bring on the onset of any sort of brain diseases
96
00:05:03.360 --> 00:05:04.120
or anything like that?
97
00:05:04.399 --> 00:05:08.879
Is there a there's some implication now of sleep disorders
98
00:05:08.959 --> 00:05:11.600
or not, you know, like poor sleep, chronic poor sleep,
99
00:05:12.000 --> 00:05:16.360
and Alzheimer's. So yeah, and they're still you know, that's
100
00:05:16.399 --> 00:05:21.120
all being studied. But lack of sufficient sleep over the
101
00:05:21.120 --> 00:05:25.360
long term increases a particular level of protein in your brain,
102
00:05:25.399 --> 00:05:28.079
which is implicated in Alzheimer's. And so they're working out now.
103
00:05:28.079 --> 00:05:29.839
In fact, I just saw something come out yesterday other
104
00:05:29.920 --> 00:05:34.319
day before about which aspect of sleep seems to be
105
00:05:34.639 --> 00:05:38.639
the critical part. You know, I'm not a sleep scientist,
106
00:05:38.720 --> 00:05:41.079
but they're drilling down into like what is it, which
107
00:05:41.079 --> 00:05:43.439
part of sleep is it that is really important for
108
00:05:44.800 --> 00:05:48.920
that clearing out that protein that's associated with Alzhemer's fascinating,
109
00:05:48.959 --> 00:05:51.079
So your brain clears out. People don't realize that when
110
00:05:51.120 --> 00:05:53.040
you sleep. You think you're just resting your body and
111
00:05:53.040 --> 00:05:55.399
your muscles, and yeah, you know, all of the rest
112
00:05:55.439 --> 00:05:57.480
of it. But actually your brain, it's like putting your
113
00:05:57.480 --> 00:06:02.120
brain through the dishwashers, like reach is clearing out toxins
114
00:06:02.519 --> 00:06:05.480
that develop during the day. Like your brain builds up
115
00:06:05.480 --> 00:06:07.480
toxins all during the day, does it. So when you
116
00:06:07.519 --> 00:06:10.839
sleep there's certain proteins and stuff that are damaging and
117
00:06:11.160 --> 00:06:14.480
when you sleep, they all get kind of washed out. Wow,
118
00:06:14.560 --> 00:06:16.839
so you're not getting enough sleep, You're you're not clearing
119
00:06:16.879 --> 00:06:17.639
out music brain.
120
00:06:17.920 --> 00:06:19.040
Yeah, toxic brain.
121
00:06:19.240 --> 00:06:21.759
Yeah, well you're it's just like eating off dirty dishes. Yeah,
122
00:06:21.800 --> 00:06:24.680
trying to think with the dirty brain. I love that analogy.
123
00:06:25.040 --> 00:06:27.199
And if it's bad for your brain, not sleeping, but
124
00:06:27.319 --> 00:06:29.279
also it can be very bad for your body.
125
00:06:29.000 --> 00:06:31.839
Because you will you all about this, you.
126
00:06:31.800 --> 00:06:35.000
Know, if you don't sleep enough, it ups a stress hormone, cortisole,
127
00:06:35.040 --> 00:06:37.199
which we've been coming back to in nearly.
128
00:06:36.959 --> 00:06:38.800
Every cordisole episode.
129
00:06:38.959 --> 00:06:42.759
Yeah, because cortisole can make you feel really crappy. And
130
00:06:42.800 --> 00:06:45.920
when you have increased cortisole in your system, it can
131
00:06:45.959 --> 00:06:49.319
shut down fat burns. So you get that tired tire
132
00:06:49.439 --> 00:06:52.040
that hangs around your belly, that's stubborn fat that you
133
00:06:52.199 --> 00:06:55.360
just can't move. My husband, he's a shift worker. So
134
00:06:55.399 --> 00:06:58.199
he if he doesn't get enough sleep, and he does
135
00:06:58.480 --> 00:07:01.480
very early mornings for a cock get up, he gets
136
00:07:01.560 --> 00:07:04.079
that tie around his belly, can't shift and even though
137
00:07:04.079 --> 00:07:08.600
he exercises and eats well, it's sleep causing that, and
138
00:07:08.720 --> 00:07:10.360
it can slow down your metabolism.
139
00:07:10.600 --> 00:07:14.279
Yeah, not getting enough sleep has impacts. Also the hormone
140
00:07:14.360 --> 00:07:18.079
levels in your body, So the hormone that's associated with
141
00:07:18.120 --> 00:07:20.959
the feeling full, like the leptin and the gorellin, so
142
00:07:21.120 --> 00:07:23.720
the hormones associated with hunger and fullness, So you feel
143
00:07:23.759 --> 00:07:26.319
more hungry, increased quarters, all, you're more likely to feel
144
00:07:26.360 --> 00:07:29.759
hungry for sugary junk foods. And then your left and
145
00:07:29.800 --> 00:07:32.360
which is what tells you you're full, goes all out
146
00:07:32.399 --> 00:07:34.439
of whack as well, so then you're likely to eat more.
147
00:07:34.519 --> 00:07:38.439
So lack of sleep or chronic sleep deprivation. When I
148
00:07:38.439 --> 00:07:40.399
talk about chronics, people always say, well, how much sleep
149
00:07:40.439 --> 00:07:44.759
is a problem. Pretty much, from four days of five
150
00:07:44.800 --> 00:07:47.199
hours or less sleep, you start seeing some of these
151
00:07:47.240 --> 00:07:52.000
negative consequences. It happens very quickly, these negative consequences. But
152
00:07:52.160 --> 00:07:58.800
so chronic sleep deprivation or interrupted sleep is basically as
153
00:07:58.839 --> 00:08:02.040
big of an implication are as big a risk factor
154
00:08:02.079 --> 00:08:06.040
for obesity as over eating or not exercising. And people don't.
155
00:08:06.040 --> 00:08:07.920
People think I'm going to attack my food and attack
156
00:08:07.920 --> 00:08:09.680
my nutrition, but they're not dealing with.
157
00:08:09.720 --> 00:08:12.120
Sleep recovery, sleep hygiene.
158
00:08:12.160 --> 00:08:14.240
They're up all night, you know, getting up all morning,
159
00:08:14.560 --> 00:08:16.399
or they're trying We see all the time people who
160
00:08:16.439 --> 00:08:19.040
are sleep deprived but trying to fit in their workout
161
00:08:19.079 --> 00:08:19.759
at eleven o'clock.
162
00:08:19.879 --> 00:08:22.720
And what do you say, They go to bed. That's
163
00:08:22.720 --> 00:08:23.720
what we say, you.
164
00:08:23.759 --> 00:08:25.959
Need to go to bed, because that is actually going
165
00:08:26.000 --> 00:08:27.959
to be just as important or more important for your
166
00:08:28.000 --> 00:08:30.480
health and fitness and everything else in your body and
167
00:08:30.519 --> 00:08:33.559
your brain. Have a nap work thirty minute workout in
168
00:08:33.600 --> 00:08:34.279
the middle of the night.
169
00:08:34.480 --> 00:08:37.639
Yeah, we always say that it's fascinating not enough sleep
170
00:08:37.639 --> 00:08:41.360
affect your hormones. But there are other physical downsides to
171
00:08:41.440 --> 00:08:42.720
not getting enough sleep, aren't they.
172
00:08:42.799 --> 00:08:45.720
Well, I think all that hormonal stuff is you know broad,
173
00:08:45.759 --> 00:08:48.279
there's a broad range of issues and so you know,
174
00:08:48.360 --> 00:08:50.840
again without going into the specifics of all of the research,
175
00:08:50.919 --> 00:08:54.799
we know that sleep problems are implicated in high risk
176
00:08:54.840 --> 00:08:57.600
of diabetes, and that's to do with the insulin.
177
00:08:57.240 --> 00:08:58.679
Yeap not cleaning out that blood.
178
00:08:58.720 --> 00:09:03.799
Yeah, higher blood pressure and hypertension, and we've already mentioned
179
00:09:03.799 --> 00:09:07.919
the Alzheimer's. It's actually linked to your longevity. So all
180
00:09:07.960 --> 00:09:10.720
of these health issues and risks associated with not getting
181
00:09:10.759 --> 00:09:13.679
enough sleep. So when you're chronically short changing yourself of sleep,
182
00:09:13.960 --> 00:09:16.000
getting less than say six hours of sleep a night,
183
00:09:16.799 --> 00:09:20.240
you know, we've talked about increased risk of currory heart disease, diabetes,
184
00:09:20.399 --> 00:09:24.480
high blood pressure, obesity, you know, the brain stuff, the Alzheimer's.
185
00:09:25.919 --> 00:09:28.279
Some studies have shown that it increases your risk of
186
00:09:28.279 --> 00:09:30.159
early death by seventeen to twenty four percent.
187
00:09:30.279 --> 00:09:30.720
Wow.
188
00:09:31.279 --> 00:09:34.519
Yeah, it's pretty it's pretty significant when you.
189
00:09:34.480 --> 00:09:38.120
Think about gob smacks like just from not enough enough sleep,
190
00:09:38.399 --> 00:09:41.120
and we've been talking about not enough sleep.
191
00:09:41.159 --> 00:09:43.559
But the other thing is that actually getting too much
192
00:09:43.639 --> 00:09:46.679
sleep also has time to ask you this also has
193
00:09:46.759 --> 00:09:49.240
health implications, So you know, we need to find that
194
00:09:49.279 --> 00:09:51.840
sweet spot. And a lot of people say, well, you know,
195
00:09:51.879 --> 00:09:54.879
how much sleep should I be getting? And for adults
196
00:09:54.960 --> 00:09:57.159
it tends to be between seven and eight hours sleep
197
00:09:57.360 --> 00:10:00.440
over night. Okay, so there's a very small umber of
198
00:10:00.480 --> 00:10:03.679
people who can survive on less, very very small noma.
199
00:10:03.679 --> 00:10:07.720
They're the anomalies. And then you know, some people maybe
200
00:10:08.039 --> 00:10:10.840
between the eight and nine hours, but anything over nine
201
00:10:10.879 --> 00:10:14.279
hours is starting to get create problems as well.
202
00:10:14.360 --> 00:10:17.159
Okay, and I have a question about naps. Does sleep
203
00:10:17.279 --> 00:10:20.639
debt build up? So if I'm deprived the night before
204
00:10:21.000 --> 00:10:23.120
and I can get a ten minute sleep during the day,
205
00:10:23.200 --> 00:10:26.919
say I've got a newborn soon, it's ten minutes here,
206
00:10:27.000 --> 00:10:30.159
twenty minutes there, Does it build up during the day
207
00:10:30.399 --> 00:10:34.799
to back to feeling good or because sometimes I'll have
208
00:10:34.840 --> 00:10:37.200
a long nap and I feel worse and I feel groggy,
209
00:10:37.279 --> 00:10:38.399
So good.
210
00:10:38.279 --> 00:10:41.399
Question that, because yes, having a nap can be really
211
00:10:41.399 --> 00:10:43.840
restorative and it can go some way to reversing some
212
00:10:43.919 --> 00:10:49.000
of these negative consequences. There is the ideal kind of nap.
213
00:10:49.080 --> 00:10:51.200
Link is that and it's found to be twenty minutes.
214
00:10:51.519 --> 00:10:53.480
Is that it? I was so happy to hear that
215
00:10:53.519 --> 00:10:56.679
because I love a nap to and it is a
216
00:10:56.679 --> 00:10:59.440
twenty minute event for me. It is absolutely twenty minutes.
217
00:10:59.440 --> 00:11:01.120
I'm awake and I'm good to go again. It is
218
00:11:01.159 --> 00:11:04.240
literally the power nap. And if you sleep longer than that,
219
00:11:04.639 --> 00:11:07.360
it actually can it puts you into a different sleep
220
00:11:07.399 --> 00:11:09.320
cycle where you can actually wake up feeling well. You know,
221
00:11:09.360 --> 00:11:12.840
when you sleep too long and you're gross yep. So
222
00:11:12.840 --> 00:11:14.320
if you're going to have a nap, you want to
223
00:11:14.320 --> 00:11:16.759
be aiming for that kind of fifty to twenty shuch
224
00:11:16.799 --> 00:11:19.080
a helpful tip, and it is. And this is where
225
00:11:19.159 --> 00:11:21.159
you raise a really good point too, if I'm not
226
00:11:21.159 --> 00:11:24.360
getting enough sleep, because oftentimes when you start talking about
227
00:11:24.360 --> 00:11:27.039
these stats and these problems of not enough sleep, it
228
00:11:27.120 --> 00:11:31.440
really scares people because parents with young babies, or you know,
229
00:11:31.519 --> 00:11:34.279
your husband's a shift worker. Yeah, people say, well, what
230
00:11:34.360 --> 00:11:38.039
do I do? You can, but I think we need
231
00:11:38.120 --> 00:11:40.360
to remember that it can be made up with a nap,
232
00:11:40.679 --> 00:11:42.759
and I think we just need to keep in mind
233
00:11:42.799 --> 00:11:46.240
that the next day, perhaps instead of cleaning the floors
234
00:11:46.600 --> 00:11:48.919
or doing the washing, you need to prioritize that nap,
235
00:11:49.159 --> 00:11:51.120
because that's the big issue with mumps is they say,
236
00:11:51.200 --> 00:11:52.840
but I'm too busy, I've got you know, you tell
237
00:11:52.879 --> 00:11:54.919
me sleep when the baby sleeps, but there's so much
238
00:11:54.960 --> 00:11:57.679
to do. But actually some of that stuff can be
