Science proves that drinking milk is more rehydration than drinking water.

Most Americans have heard that eight glasses of water a day are needed to keep their bodies hydred, but surprisingly, there is little data to support this recommendation.
a new "drink moisture index" now offers fact-based advice on how best to rehydration, the New York Times reported on July 6.
index is based on a study published in the UK in December.
the study tracked how long they stayed in the body after drinking 13 common drinks.
"Over the past 25 years, we've done a lot of research on post-exercise rehydration," said lead author Ronald J. Loughborough University, an expert on rehydration at Loughborough University. "Then we thought we should look at the rehydration of typical consumers who are not in the movement, " says Ronald J. Maughan.
reported that the rehydration index is modelled on the famous glycemic index, which measures the body's response to carbohydrates in different foods (glycemic index is used to help individuals control glucose insulin response).
guidelines for the new rehydration index are that some liquids last longer in the body than others and are better at rehydration.
after all, if you drink a glass of water and quickly drain half the water out of your urine, you don't actually add 8 ounces of water, you just add 4 ounces.
study in the UK identified a rehydration index for 13 common drinks.
72 male participants, aged about 25, drank 1 litre of water as a benchmark.
1.0 after two hours, the participant's body moisture content (i.e., water that was not discharged through urine) was specified.
all other beverages are evaluated in a similar manner and then scored with water comparisons.
drinks with a score of 1.0 had higher water retention than water, and beverages with a score of 1.0 had a higher excretion rate than water.
results showed that four beverages had a much higher rehydration index than water: oral rehydration solutions, such as electrolyte liquids; skimmed milk; whole milk and orange juice.
the top three rehydration index is around 1.5, while the index of orange juice is slightly higher than water, at 1.1.
oral rehydration solution is designed to combat severe dehydration, such as those caused by chronic diarrhea.
"It's a very clever study," said Lawrence Armstrong, a water rehydration expert at the University of Connect and a recent chairman of the American College of Sports Medicine.
"Why is milk so effective in rehydration?" "Normally, drinking means that the kidneys have to create more urine to remove excess water, " Says Maughan, "but if the drink contains nutrients and electrolytes such as sodium and potassium, like milk, the stomach drains more slowly and has less severe effect on the kidneys."
, perhaps surprisingly, drinks containing moderate amounts of caffeine and alcohol or high levels of sugar are no different from the water supplementation index, the Report said.
other words, coffee and beer don't dehydrated people - although this is contrary to popular belief - and that ordinary sodas are as efficient as water.
Caffeine is a diuretic, but the caffeine concentration in most coffee drinks does not work, " Says Maughan. "
, such as distilled spirits, is the exception to very strong coffee or alcoholic beverages.
" The rehydration index may prove useful when deciding when to drink what kind of drink.
, for example, if you're driving for long periods of time and can't get a lot of fluids (and can't go to the bathroom often), it's better to drink milk than water or iced coffee because it has a high water index.
, don't forget that milk is hotr than water, so don't drink too much.
severe dehydration is a rare exception to severe exercise, extreme conditions or illness, several studies have shown that high temperatures and dehydration can lead to higher mortality rates in hot weather, the Report said.
"When a heat wave hits, the death rate rises dramatically, mainly because people don't get enough water to make up for the increased water loss," Moeen said.
that in hot weather, it's important to monitor your body's moisture status throughout the day.
he recommends paying attention to thirst and rehydration when needed.
, if your urine color is dark yellow, you'll need a refreshing drink.
