isn't really that important to stay
0:02
hydrated for better performance and if
0:04
it is what's the best drink for the job
0:07
let's talk about that
0:08
[Music]
0:12
how's it going guys my name is Richie
0:13
Kerwin and today we're going to talk all
0:15
about staying hydrated what it means why
0:18
it matters especially for sports and
0:21
what common drinks are better or worse
0:23
for keeping you in that hydration sweet
0:25
spot I'll also answer the common
0:27
question of whether tea and coffee are
0:30
any good for improving hydration I also
0:32
want to mention that a lot of the info I
0:34
got for this video came from a great
0:36
review by Belleville so if you want to
0:38
read geek out on the topic you can find
0:40
the paper and all the references from
0:42
the video in the comment section below
0:43
so just in case you weren't already
0:45
aware if you don't drink you die now
0:48
while you're recovering from that
0:49
shocking Revelation it's also worth
0:51
mentioning that most of what you are
0:53
made up of 70 in fact is water which is
0:57
found inside our cells in the liquid
0:59
surrounding them and in the various
1:01
liquids inside our bodies like blood and
1:03
lip so as you might have guessed water
1:06
is pretty important
1:08
we lose water in a few different ways
1:10
through urine when you pee in our sweat
1:13
and through our breath as water Vape
1:16
that means when we exercise we lose more
1:19
water than normal because we usually
1:21
sweat more and breathe harder but you
1:23
might be asking why does this even
1:24
matter well if you are even slightly
1:27
dehydrated your body's ability to
1:29
function is impaired and there's a lot
1:31
of evidence to show that dehydration
1:32
leads to problems with things like
1:34
thermoregulation or our body's ability
1:36
to regulate our temperature
1:38
it can cause excess cardiovascular
1:40
strain and changes in blood pressure
1:42
blood flow and heart rate
1:44
and it can make it harder for our
1:46
muscles to work properly one way to
1:49
think of it is like this
1:51
if you exercise a lot and don't take in
1:53
enough fluids to replace the water you
1:55
lose in sweat on your breath your body
1:57
needs to get water from somewhere and it
2:00
takes it directly from your blood
2:02
the problem with this is if you lose
2:04
water from your blood you have less
2:07
blood volume and your heart needs to
2:09
work harder to pump that blood around
2:11
your body because of a drop in blood
2:13
pressure this can really cause your
2:15
performance on the field or in the gym
2:17
to drop and makes exercise seem a hell
2:21
of a lot harder than it should be so if
2:23
you want to go into the gym and train as
2:25
hard as you possibly can which you
2:27
should because harder higher volume
2:29
training can lead to more gains in
2:31
muscle size and strength or if you just
2:33
want to perform at the best of your
2:35
ability in any sport
2:37
being properly hydrated is essential so
2:40
before we talk about how best to hydrate
2:42
we should probably mention how you know
2:45
if you're properly hydrated in the first
2:46
place
2:48
and there's a very easy way to do it
2:50
you can just check out the color of your
2:52
pee
2:53
you see if you're dehydrated there will
2:55
be less water in your pee and a higher
2:57
concentration of solutes and waste
2:59
products which means your pee will be
3:01
darker in color while you're peeing you
3:03
can compare the color of your pea to
3:05
some common eight or seven color scales
3:07
which give you an idea of how hydrated
3:09
or dehydrated you are
3:12
as you can see in this chart if your
3:14
urine is very pale or straw colored like
3:16
in colors one to three you're doing fine
3:19
if your pee is more of a yellow or
3:22
orange color like in colors four to six
3:24
then you're dehydrated and you need to
3:26
drink more
3:28
and if your pee is dark orange or brown
3:30
like color seven or eight
3:32
for the love of God please just drink
3:34
something
3:35
basically if you spend most of the day
3:37
peeing a very light colored yarn it's a
3:39
sign that you're taking care of your
3:41
hydration and this is why I don't tell
3:43
people to drink X liters of water every
3:46
day because the number is different for
3:48
everyone and depends on their body size
3:50
genetics their sweat rates and how
3:52
physically active they are
3:54
that's why basing how much you drink on
3:56
your urine color is much more useful
3:58
because it tells you what you need for
4:00
your body on the other hand if your pee
4:03
often comes out completely clear you're
4:05
probably over hydrating and that could
4:07
lead to a loss of many salts and
4:09
electrolytes it's always possible to
4:12
have too much of a good thing so the
4:14
next thing you probably want to know
4:16
what's the best drink to hydrate you or
4:19
to help get water into your system well
4:22
if you thought it was water that's
4:25
actually a pretty good guess water is
4:27
considered the standard when it comes to
4:29
hydration and scientists have developed
4:31
a beverage hydration index or bhi which
4:34
is based on the volume of urine that you
4:36
produce after drinking in relation to
4:39
still water which is the standard
4:41
so how do other drinks compare to plain
4:44
old water well as you can see sparkling
4:47
water is virtually identical but Cola
4:50
seems to be a little more hydrating
4:52
although it's not statistically
4:54
significant
4:55
diet cola and sports drinks are
4:57
virtually the same as water too
5:00
but next up is something called oral
5:02
rehydration solution which is
5:04
significantly more rehydrating than
5:07
water
5:08
well what's an oral rehydration solution
5:10
I hear you ask well it's a drink that's
5:13
specifically designed to replace fluids
5:15
in order to prevent and treat
5:17
dehydration it's often used in cases of
5:19
chronic diarrhea or in diseases like
5:21
cholera where many people die of
5:23
dehydration because they lose so much
5:25
water you know into poop so oral
5:30
rehydration Solutions are really good
5:31
for hydration because in addition to
5:34
water they contain small amounts of
5:36
sugar and electrolyte salts like
5:38
potassium and sodium and that's what
5:40
makes the absorption of fluids in oral
5:42
rehydration Solutions much more
5:44
effective than water alone
5:47
that's why many sports drinks contain
5:48
sugar and electrolytes to improve water
5:51
absorption in the gut to keep athletes
5:53
well hydrated while competing the
5:55
presence of sugar is also why orange
5:56
juice the next on the bhi list is more
5:59
effective than water too after that
6:02
lager coffee tea are all pretty equally
6:05
hydrating as water
6:07
I hear a lot of people saying that you
6:09
can't drink tea or coffee to get
6:10
hydrated and that's absolute
6:13
while tea and coffee do have very slight
6:15
diuretic effects which means that they
6:17
make you pee a little more the amount of
6:19
water that they contain is more than
6:21
enough to help keep you hydrated
6:24
obviously that wouldn't be the case if
6:25
you're trying to rehydrate it with
6:27
espressos because the amount of water
6:28
they contain is so little which yeah tea
6:31
and coffee are perfectly fine to help
6:33
you get more water into your system
6:35
finally at the end of the bhi list are
6:38
whole and skimmed milk with skim milk
6:41
being the most hydrating of all the
6:43
drinks tested and again this is probably
6:46
due to the content of sugars electrolyte
6:48
sauce and possibly protein which improve
6:51
the absorption in the gut
6:53
so why would whole milk be a little less
6:55
hydrating than skimmed well we know that
6:58
fat can actually slow down gastric
6:59
emptying a little but it's still better
7:01
than plain old water
7:03
before I finish on the drinks I also
7:04
should point out that you can also get
7:06
water from fruits many fresh fruits and
7:09
salad vegetables can provide a lot of
7:11
hydration and can definitely contribute
7:12
to your daily water intake so don't
7:14
forget to include plenty in your diet
7:17
our final load for a practical take-home
7:20
point you can stay perfectly hydrated
7:22
throughout the day with a range of
7:25
different drinks and foods and keeping
7:26
an eye on the color of your pea is a
7:28
pretty decent indicator of how well
7:30
hydrated you are but if you're training
7:33
for a long time or especially if you're
7:36
competing in a sport where you sweat a
7:37
lot or in high temperatures drinking
7:40
beverages with added sugar and salt like
7:42
orange juice or skim milk if you
7:44
tolerate milk may be optimal for
7:46
replacing your lost fluids as quickly as
7:49
possible you can also buy plenty of
7:51
isotonic Sports beverages which do the
7:54
same thing so did that clear everything
7:56
up about hydration
