Video summary
Research conducted by pioneer Wendy Troxel reveals a significant discrepancy between how couples perceive their sleeping arrangements and objective sleep data, often leading to what is termed a "sleep divorce" where partners separate during the night due to poor quality rest rather than relationship issues. While one in four people report not sharing a bed with their partner, anonymous surveys show that up to one-third of couples actually wake up in different locations within the same room or on a couch. Objective measurements using sleep trackers and polysomnography consistently demonstrate that sleeping together results in worse average sleep quality compared to sleeping separately due to physical disruptions like movement and snoring. However, subjective reports often contradict this data because many individuals feel safer and more intimate when sharing a bed with their partner, creating a societal bias where separating is stigmatized despite the physiological benefits of isolation for restful slumber. The impact of sleep deprivation on intimacy and reproductive health is profound, particularly regarding sex hormones that drive libido and sexual pleasure. When men are deprived of just one hour of sleep over five nights, their testosterone levels drop to those equivalent to a man ten years older; similarly, women experience declines in follicle-stimulating hormone, luteinizing hormone, progesterone, and estrogen. Conversely, adequate rest significantly boosts desire for intimacy, with research showing that every additional hour of sleep increases a woman's libido by 14%, an effect comparable to pharmacological treatments like Flibanserin which only improve libido by roughly 23-24%. Furthermore, sufficient sleep enhances physical aspects of sex through greater vaginal lubrication and genital sensitivity in both men and women. Beyond the physical realm, poor shared sleep blunts empathetic sensitivity and damages conflict resolution capabilities because it affects the prefrontal cortex first; this leads to increased arguments as partners become more adversarial rather than cooperative within their relationship dynamic. To address these challenges without abandoning intimacy entirely, Dr. Walker suggests a non-binding approach where couples experiment with sleeping in separate locations for two weeks using curiosity and open communication. A practical solution involves maintaining the "bookends of sleep"—sharing affectionate rituals like kissing or cuddling before bed and upon waking—while utilizing physical barriers to prevent disruption during deep sleep phases. Common disruptions include unconscious movements fighting over territory on top sheets, rolling over which wakes a partner back into shallow sleep cycles, and snoring issues where men are more prone to sleep apnea while women suffer from insomnia linked to higher rates of anxiety disorders. Innovative solutions like the "two-duvet" setup or the Swedish method utilize twin beds placed side-by-side with separate duvets to segregate both top and bottom surfaces completely, a strategy already employed by high-end hotels like Equinox in New York that feature cooled mattresses and dual bedding suites. Ultimately, the relationship between sleep and intimacy is bidirectional, as sexual activity associated with orgasm can improve subjective sleep quality by approximately 70% for men and 64% for women due to the release of bonding hormones like oxytocin and vasopressin during pro-social activities. Even solitary masturbation provides a substantial benefit, improving reported sleep quality by about 50%, likely because it triggers a transition from sympathetic activation (fight or flight) to parasympathetic quiescence required for deep rest. While the hormonal benefits of partnered sex are slightly higher due to added social bonding effects, individuals without partners can still achieve significant physiological recovery through orgasmic release. The discussion concludes that prioritizing sleep hygiene is essential not only for individual health but also for sustaining a healthy relationship dynamic, suggesting that couples should consider early bedtimes or separate sleeping arrangements if their current setup compromises the restorative power of sleep necessary for superior libido and emotional connection.

talk to me about the relationship
between sleep and relationships yeah
there's some really great research on
this um Pioneer in this field is Wendy
Troxel wrote a great book um and what we
find is that if you survey people and
you ask do you sleep in the same bed
together one out of four people will say
that they do not sleep in the same bed
and if you then survey them
anonymously be because there's such a
stigma associated with not sleeping
together about one in three couples will
say I wake up in a different location
than this bed that I went to sleep in
with my partner so in other words they
got up during the night and they just
went and they on the couch and yeah
exactly so so it's certainly it's
certainly a common practice and it's
increasingly so this idea I think poorly
named which is this idea of a sleep
divorce to prevent a real one and I'm
not suggesting again that it is a one-
siiz fits all it's absolutely not some
couples can sleep together and they
sleep really well and they have a
preference for that what's interesting
though is that if you measure them
objectively you always see that when
couples sleep together versus when
couples sleep separately their sleep is
always objectively as we measure it with
sleep trackers or you know
polysomnography in the laboratory it's
always worse when they're sleeping
together on average than when they're
sleeping separ separately however if you
ask them subjectively what do you think
of your sleep they'll say Well about
half of them will say I actually feel my
sleep is much better quality when I'm
sleeping with my partner versus when I'm
not some of that has to do with perhaps
the societal bias that they think they
have to cleave to others it's about
safety that they just feel safer and
others it's just more intimate but what
we have definitely found is that
it's if you start to undersleep a male
if you short sleep them and if you look
at the average data they could be in bed
let's say 7 hours with a partner they
could be down to around 5 and 1/ half
hours because of the Sleep disruption if
you put a male healthy male in their 20s
on 5 hours of sleep for five nights they
have a level of testosterone of someone
who's 10 years older than them so and
you see equivalent impermanence in
female reproductive Health follicular
stimulating hormone luttin ing hormone a
progesterone these are all critical sex
hormones that promote Superior libido
drive and it also promotes Superior
sensation and sexual pleasure during the
act of intimacy so firstly when you're
under slept and again this is not a
one-size fit all but for those that it's
not working for the stigma in society is
that if you're not sleeping together
you're not sleeping together but in fact
the opposite seems true because you
repete your sex hormones we also know
that for every one hour of sleep that a
woman gets an extra hour of sleep that a
woman gets her desire to be intimate
with her partner increases by
14% wow now if you think about the
latest libido drugs for women things
like
fesi those will improve libido by about
23 to 24% that's a pharmacological brute
forcing agent but here of sleep one hour
of sleep and you're you know you're
getting there so all of a sudden you
know all the guys now are probably
saying calling their girlfriends or
their wife honey we need to go to bed an
hour early yeah should we get into bed
an hour early and let's sleep in come on
let's have a um so so there's certainly
a a superior benefit when you are
sleeping well as a couple your physical
component of intimacy is improved we
also know that when couples are sleeping
well uh from a female perspective at
least you get by way of those sex
hormones you get greater vaginal
lubrication which leads to higher
pleasure during sex and you get greater
sensitivity of the genitalia for both
man and woman in terms of the intimacy
the other component though is the
psychological
component when couples are not sleeping
well for example when they are sleeping
together firstly their empathetic
sensitivity is
blunted second L as a consequence they
end up butting heads more in the
relationship and furthermore because
they're prefrontal cortex which is the
kind of higher order reasoning logical
area of the brain that's the one that
goes first in terms of sleep deprivation
it's the same one that is there designed
to do conflict resolution so you are you
are in in feed as an organism to have a
co-opted relationship that's emotionally
m
and designed to be part of a team versus
adversarial and combative and so shorter
nights greater fights that's what data
starts to
demonstrate then you can ask well okay
if I design if I decide to to sleep in
separate
rooms how can I firstly approach that
with my partner and how can I design it
the first thing I would say is approach
your partner with
curiosity and a non-binding agreement go
to your partner and say
look what have you ever thought about us
maybe trying to sleep in separate
locations so we sleep better so we
better together as a consequence would
you be open to just saying look for the
next two weeks we try sleeping apart and
if we agree that it doesn't work we just
go back to sleeping
together would you be open to that idea
so you make it non-threatening you
approach from a level of curiosity and
you don't make it binding that from this
point forward this is what we're doing
then how do you design it what we most
of us miss by sleeping together is the
bookends of sleep because in between
we're largely
non-conscious so you can say look
if before we go to sleep I'm just going
to come into your room and we're just
going to have a kiss and a cuddle and
we're going to do what going to do the
front end of sleep and then whoever
wakes up first you can go through to the
kitchen make the coffee and the person
who is waking up second just text your P
it and now this is you know utopian
world where no one's rushing out the
door to go to work but if you have the
chance then just text your part and say
hey I'm awake come in give me a cuddle
give me a kiss and that way you get what
you wish for which is the buck ends of
sleep of intimacy cuddling and all of
those good things but you still get to
sleep apart what is it that's happening
when people sleep that's causing the
disruption for the most part it's
usually two things it's the it's the
territorial non-conscious fight for the
top surface called the cover right okay
yeah the kind of tug of war and the
second is the distribution of
disturbance along the base of the bed
which is I'm tossing and turning and you
therefore may not even remember that I
woke you up but my movement still train
going past outside and it correct
yeah and you roll over you're back into
shallow sleep and then the other person
has rolled over and now that was just at
the time and they're adjusting
themselves just at the time that you
fell back asleep after you were the one
who caused it and now you're awake again
so firstly there's the non-conscious
physicality of top and bottom sort of um
surfaces being moved around and then the
other is snoring it's the other you know
if you ask a lot of usually women
because now women get sleep apnea and
men get sleep apnea it's just that it's
probably rate of about 3:1 ratio men
getting sleep apnea it's about the
opposite for insomnia far more women
have insomnia than men it's not to say
that men don't have insomia that high
neuroticism it's usually because anxiety
disorders are about twice as common in
women than in men and anxiety just as we
spoke about is one of the principal
underlying mechanisms through which we
understand this thing called insomnia
okay did you see on Reddit quite a while
ago that famous couple sleep study they
did where they ended up with the twv
solution
yeah what do you make of that because
I've had a number of friends I have one
friend who I'm not going to name I have
two friends one friend who a year ago
actually it was done on the show it was
George so George um fully committed to
this having read that study on Reddit
and he had the
classic partner's great but [ __ ] we
really the sleep is is lower quality
than it should be and he was very much
prioritizing it Allah Dr Walker um and
he pivoted to a two solution and yeah do
you want to explain a two solution just
for folks who two dues two two duv
covers on the top of the bed uh there
couple who had maybe using an aura ring
or something similar had tracked their
sleep the single best determinant of the
wife's good night sleep was the husband
being in the bed the single best
determinant of a bad night's sleep for
the husband was the wife being in the
bed and for for clarity I think it was
the same it was more of a decrease in
Sleep Quality for the man as being on
the period was for the woman uh so that
was the sort of rate extent of yeah yeah
exactly the the rate of impact and they
tried everything lots of different
solutions they didn't want to go to a
twoed solution so they went to a two
Dove solution which presumably is as you
said fixing the top surface there no
longer a chug of War because it's two
separate uh surfaces to play on so I
guess is there not first off there must
be companies I look at all of the eight
leaps and the you know the the Helix
mattress and stuff like that uh an extra
extra wide bed that's got maybe some
sort of
segmented um you know the honeycomb
thing that kind of portions off in the
Middle with a two V solution I mean like
how big does a bed have to be before
it's one bed that is essentially two do
you know what I mean like have you
looked at soltion imagine the real
estate territory we're talking about
here at some point getting it's just an
entire bedroom that's one mattress yeah
exactly it's a soft play area for for
parent keep your bedroom chitchat to
yourself Chris what do you think what do
you think about the two V solution have
you looked at that has it ever been
replicated and then what about um
Solutions maybe people don't have
sufficient bedrooms in the house to be
able to move to two what what can people
do to make sleeping together better uh
yeah yeah I actually think the two-
solution is a great one in fact if you
look there's um Equinox hotels uh the
chain uh principally in New York right
now if you go in they're highly
optimizing sleep and I'm just stting to
have conversations with them to to see
if I can help them with that they
already do this where the bed will have
it's dressed in essentially two separate
Suites of you know your sheet they've
sleep on them all as well right they've
got a cooled mattress I I don't know if
they have ate sleep yet okay but
certainly they yeah they probably I'm
sure they do but they will they've
already figured this out and kind of a
genius move but there's a more extreme
version of that and it's called The
Swedish method and it sounds highly
salacious just turns out that this was a
method pioner in Sweden which is simply
that you get two twin beds you put them
together side by side so you're still
sleeping essentially next to each other
but there is complete separation between
church and state as it were and
therefore the bottom and the top is
segregated rather than the tuve were the
bottom is common duvet is split and this
way with the Swedish method you do top
and bottom wow which sounds very a
little bit it does sound Swedish um
anything else I'm so glad you're not
cutting that part anything else to say
on uh sleep and relationships um I would
say that
certainly sleep
affects sex meaning that when you are
getting sufficient sleep it can promote
a greater degree of physical intimacy
and pleasure sex also impacts sleep
though and what they've what we found um
we in the Royal Way of the Sleep field
is that sex that is associated with
orgasm ends up producing about a 70%
Improvement in subjectively reported
Sleep Quality regardless of time of day
regardless of time of day it's higher in
men than in women so women it's about a
64% Improvement in men it's about a 72%
Improvement but it's still you know
demonstrable now for some people
listening maybe you don't have a partner
so but all is not lost because it turns
out that masturbation associated with
orgasm results in about a 50%
Improvement why in part of it is
probably because of certain other social
bonding hormones like Pro well
probably if you look at some of the data
there is probably vasor press in for men
mhm and then if you look at that sort of
the the classic hormone of bonding which
you have you spoken about oxto oxytocin
before yeah so oxytocin that's more so
in females than in males men is so
fascinating and it's oh don't get me
yeah and I started to speak to Peter you
know because he used to use it for all
sorts of sleep related reason uh but
those hormones typically are released by
way of pro-social activity now when
you're by yourself you don't get that
added benefit so there is something
about and I think what's happening with
orgasm is that you're very sympathetic
you're very fight oflight you're getting
very activated your heart is racing but
then afterwards it's that kind of
cigarette moment in the movies where all
of a sudden you're just spent and you go
all the way over into the
parasympathetic quiescent State and
you're kind of done and that's the state
that you need to be in so firstly I
think from a hormonal and a nervous
system perspective that's why sex by way
of orasm is beneficial the benefit of
couples or you know at least more than
one person producing that added benefit
from 50 to 70 is probably because of the
pro-social hormones but nevertheless you
can still get you know 50% of the way
there so in terms of adding sleep credit
you know you're making money hand over
it's a good making money hand over fist
but maybe I wouldn't say that let's not
talk about fist um there are thousands
of dollars of Lights pointed at my face
right now but because of mantis sleep
mask all I can see is complete Blackness
literally I it feels like I'm in Pitch
Black at the moment that's why I'm a
massive fan of them the problem with
most sleep masks is that they're made
with cheap materials they let too much
light in they push up against your
eyelids and they're just uncomfortable
especially for side sleepers look at
that you can see here how amazing this
like the inner part of the eye mask is
where it doesn't touch your eyelids at
all mantis's masks were made with all of
this in mind to make the perfect mask
for all types of sleepers made of soft
breathable materials they've got an
adjustable strap that can fit even the
weirdest shaped head Dr Mike isrel this
could be for you I use this mask every
night when I'm at home I use it when I'm
on travel there's one in every single
travel bag I've got even for Midday naps
this thing is unbeatable so comfortable
and they've got a 60 night sleep trial
so you can buy it and sleep with it on
for 59 nights if you don't like it for
any reason they'll give you your money
back plus they offer free us shipping
