How long can a man survive
without drinking water? Not long I believe, because every system in the human
body requires water to function properly. The muscles, kidneys, blood lungs and
your brain, etc, are all made up of some percentage of water. Water helps the
body to flush out waste and toxins in order for the body to transport
nutrients. We lose water when we breathe, and daily through urine and sweat.
When water level drops beyond the optimal, you become mildly dehydrated, your
energy level decreases and your metabolism slows.

To stay hydrated, you should
replenish your fluids throughout the day. Anytime you feel dehydrated, it is
advisable to drink water that is close to room temperature because ice water
may feel refreshing, but it will sit in your stomach until it warms up. So,
when you need to rehydrate in a hurry, go with fluids that are close to room
temperature.
For you to know how much
liquid you need every day, it is important to identify the signs that you may
be approaching dehydration.
Dark Yellow Urine – The first sign that you are not
drinking enough water is when your urine becomes dark yellow. In the real
sense, urine should be light yellow in colour and so, when a person does not
drink enough water, it makes the kidney to excrete a higher concentration of
waste products in the urine, this higher excretion will result to dark urine.
You may also notice darker urine when you consume some medications; if you
notice a temporary change in your urine colour, what you should do first is to
consider if you have consumed something that could change the colour of your
urine. After that, the next thing is to increase your water intake and observe
if your urine colour changes to normal. After all this observation and your
urine still stays dark for a long period of time, then it could be a sign of
more serious health concerns; you should see the doctor for proper medical
check.
You Get Exhausted Easily – Another sign that you are dehydrated
is that you start feeling exhausted without doing anything serious; this will
cause your metabolism to slow, your body begins to conserve its energy, leaving
you feeling so tired. Mild dehydration also reduces the volume of blood in your
body, forcing your heart to work harder to pump oxygen and nutrients to all of
your cells. When your heart is working less efficiently, you may feel exhausted
even though you have not engaged yourself in any vigorous action.
Feeling Hungry – The signals your brain sends when you need calories
and when you need fluids originate in the same place and this can be mistaken
for each other. So anytime you feel hungry, don’t rush for food immediately, it
is advice that you drink water and wait for like 10 to 20 minutes; after 10 to
20 minutes and you still feel hungry then you can go ahead and eat.
Bad Breath – Your saliva produces antibacterial properties which
prevent nasty microbes that are the source of bad breath from setting up
residence in your mouth. Dehydration reduces the volume of saliva you produce
often resulting in unpleasant odours in your mouth.
Constipation – Dehydration is one of the most common causes of
constipation and constipation can often be resolved by increasing water intake.
If you are not fully hydrated, your body will try to absorb water from wherever
it can. Naturally, lack of water will lead to harder stools that are difficult
to pass. To prevent this, ensure you drink adequate amount of water and if you
are the type that drink enough water every day and you still face the problem
of constipation, then you should consider other causes of constipation: See a
doctor!
