According to a study from the Journal of Strength and Conditioning Research, rehydration from a state of mild dehydration can be achieved with 20.3 oz (600ml) of water or an electrolyte beverage in 45 minutes.
According to a recent study from the Journal of Strength and Conditioning Research, your body can alleviate mild dehydration in 45 minutes with 20.3 oz (600ml) of water.
If you are dehydrated, it's important to rehydrate as quickly as you can. With beginning symptoms of dehydration, you can rehydrate by consuming fluids that contain electrolytes, such as sports drinks or oral rehydration solutions.
In general, however, it usually takes about two hours for your body to rehydrate fully after drinking a significant amount of water. As for how you should rehydrate, water is the best choice. Sports drinks, such as Gatorade, can be helpful for athletes who need to replenish electrolytes.
Milk is more hydrating than water
For example, milk was found to be even more hydrating than plain water because it contains the sugar lactose, some protein and some fat, all of which help to slow the emptying of fluid from the stomach and keep hydration happening over a longer period.
Chugging as much water as you can all day is likely not the best or most efficient way to stay hydrated, and it's technically possible to overdo it. There is such a thing as overhydration that causes some unwanted and potentially dangerous side effects.
Drink an ORS Before Bed
Instead of drinking a glass of water, drink an oral rehydration solution like DripDrop ORS, which also contains electrolytes that are essential for hydration. Try to drink the ORS an hour or two before bed so you don't wake up in the middle of the night to use the restroom.
In fact, water may not even crack the top five of the most hydrating drinks out there. According to a study from Scotland's St. Andrew's University, milk, Pedialyte and soda top the list of most hydrating beverages.
Tea (or Iced Tea)
You won't be surprised to learn that hot tea and iced tea are excellent hydrators—tea is a water-based beverage after all! Even caffeinated teas can still be hydrating.
Here is one more reason to enjoy that morning cup of joe: “Coffee counts toward your daily water intake,” says Lauren DeWolf, MS, RD, a registered dietitian with Sharp Rees-Stealy Medical Centers. The water in coffee, tea and other caffeinated beverages helps us meet our daily fluid needs.
You'll feel less hungry and may even lose weight. You'll probably experience more comfortable digestion (less heartburn). Bowel movements might be easier and more regular. Your teeth and gums will be healthier and more resilient.
Best Overall: Gatorade
The levels of electrolytes (sodium and potassium) are moderate and sensible with 160 mg of sodium and 45mg of potassium per 12 fluid ounce serving. You can also find Gatorade varieties with higher sodium, zero sugar or no calories depending on your needs.
“If you don't get enough water, hard stools and constipation could be common side effects, along with abdominal pain and cramps.” Dull skin. Dehydration shows up on your face in the form of dry, ashy skin that seems less radiant, plump and elastic. Fatigue.
Drinking beverages that contain electrolytes can both rehydrate you quicker than plain water and it can keep you feeling hydrated longer than plain water.
Watermelon (92%) It's no surprise that watermelon will hydrate you. But, like tomatoes and other red fruits and veggies, it's also a great source of lycopene.
Staying hydrated is so important on a daily basis, but even more so when it's hot and kids are so active! I've written a post about hydration here before because it's just so important. Anyway, moving on, Hydralyte have released a whole bunch of Electrolyte products for rehydration that you can use everyday.
“Some of the common symptoms of electrolyte imbalances include muscle twitching and muscle cramps, increased thirst, poor endurance, salt craving and irritability,” says Zachary Sprague, DO, a family medicine physician with expertise in sports medicine at Scripps Coastal Medical Center Carlsbad.
It hydrates you
This myth comes from a study funded by Gatorade that found people who drank their product were better hydrated than if they drank water—but only because they drank more fluids. If you drank the same volume of water versus Gatorade, you'd be equally hydrated.
To meet your fluid needs throughout the day, choose water most often. Remember that other fluids like milk, coffee, tea and juice also count towards your daily fluid intake.
