A fair amount of people drink water before bedtime and
after they wake up. Some people doubt that whether drinking water before
bedtime and after wake up is harmful and beneficial. One the one hand, people
felt that they could not enter deep sleep state by doing this. On the other
hand, people believe drinking before bedtime and after wake up could bring lots
of benefits: promoting sleep, lose weight, hydrating and toxin cleaning.
Colwell, who is from University of California Los Angeles School of Medicine,
made a study about vasopressin release increases late in sleep. I believe this
study could reveal many secrets of water drinking and health issues. Moreover,
many other studies suggest other benefits of water drinking under a specific
time period and amount.
According to Colwell, “During the late sleep phase, the brake (on the
osmosensory response) is released, as the animal isn’t drinking, and more water
needs to be retained.” This report illustrates that human body would
lose water (dehydration) during the late night. That is the reason why people
would feel thirsty after they wake up. Drinking water before the bedtime and
wake up is a great way to prevent dehydration and keep healthy. Moreover, the
report made further study on vasopressin release influence human’s water
balance during the late night. Vasopressin would be produce and release by MNCs
and promote water re-absorption (Colwell). More importantly, MNCs, the
mechanism of water balance system in human cavity, is influenced by human
internal biological clock. Putting this conclusion in another words, people who
have irregular life style and disturbance of internal biological clock would
keep the hobbit that drinking water before sleep and after wake up to keep
water balance.
Except preventing dehydration during the
late night, drinking water could give human beings a large amount of other
benefits. To be specific, if people drink a glass of water before meal, they
would reduce the amount of sugary beverages during meals. As a result, people
would lose weight. Goodwin prove that fact that drinking water could help
people lose weight through some scientific reports. Two groups of people (aged from
55 to 75) are separated by researchers and all people have the same diet. One
group of them should drink two glass of water before 3 meals per day while the
another group don’t. Those people who need to drink water before meals lost
15.5 to 11 ponds compared with others during 12 weeks. Also, drinking water
could help human recover more quickly from different types of infections. Furthermore, drinking water regularly could
prevent kidney stones and constipation. Finally, Keeping drinking water could control
the viscosity (resistance to fluid) of blood. If blood is thick and have a high
viscosity, human brain would be less active.

The topic of water drinking seems interesting and helpful. I do not realize that drinking water before going to bed has positive effects on our health until reading this post. Good research.
