After drinking milk, the study volunteers produced less urine (and therefore retained more fluid) than with water or a sports drink (Powerade). Therefore, milk was considered to provide better hydration.
Intravenous rehydration (IV injection, or “drip”)
The fastest method for rehydrating patients is the medical technique of intravenous (IV) fluid replacement. This sends electrolyte-balanced fluids directly into the blood stream so it gets distributed by your blood cells throughout the body almost immediately.
peeing less often than usual. feeling dizzy or lightheaded. feeling tired. a dry mouth, lips and tongue.
With beginning symptoms of dehydration, you can rehydrate by consuming fluids that contain electrolytes, such as sports drinks or oral rehydration solutions. There are also foods available that have a high water content, such as fruits and vegetables. These will also help with rehydration.
Two early signs of dehydration are thirst and dark-coloured urine. This is the body's way of trying to increase water intake and decrease water loss. Other symptoms may include: dizziness or light-headedness.
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.
Gatorade, because of its electrolyte content, helps to restore the lost electrolytes and keep a person hydrated, during intense activity. It can also replace electrolytes, during times of illness, such as stomach viruses.
Gatorade contains 160 milligrams of sodium and 45 milligrams of potassium per serving, whereas Powerade contains150 milligrams of sodium and 35 milligrams of potassium per serving. In comparison, Gatorade is slightly better at replacing lost electrolytes.
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.
Watermelon - Just like cucumber, watermelon in 90% water, which, mixed with natural sugars and potassium, makes it one of the best electrolytes-rich foods to include in your diet.
Pedialyte is the recommended beverage of choice for the elderly. Gatorade is a sports drink that's meant to restore electrolytes after exercise, but Pedialyte can renew electrolytes lost from exercise and other means, such as sweating, diarrhea, or fever.
Not sure if you're dehydrated? One of the easiest ways to tell is by checking the color of your urine. If it looks clear or pale yellow, then you're drinking enough water. But if your urine is a darker yellow or an amber color, then it's time to hydrate.
Key takeaways: The caffeine in coffee gives it diuretic effects, meaning it causes your body to pass more urine. But these effects are too mild to cause dehydration, especially if you're a regular coffee drinker. Coffee may even be hydrating for some people, because it contains a lot of water.
Bananas. The classic healthy post-workout snack, bananas are packed with potassium, one of the most important electrolytes. Dehydration can cause an imbalance of electrolytes in the body, so eating potassium-rich foods when you're feeling parched should help stave off the symptoms.
Diabetes insipidus is a condition in which your ability to control the balance of water within your body is not working properly. Your kidneys are not able to retain water and this causes you to pass large amounts of urine.
Intravenous (IV) fluids and IV medication -- including some that contain electrolytes or medications that help normalize electrolyte levels -- are often used. Other IV medications may need to be used to treat underlying causes of dehydration (for example, IV antibiotics for dehydration caused by infection).
Fruit juices such as orange juice, cherry juice, and watermelon juice are all good sources of magnesium, potassium, and phosphorus. According to the FNDDS, the average school container (124 grams) of 100% orange juice provides : 13.6 mg of magnesium.
It is the high sodium levels in sports drinks, such as Gatorade and Powerade, on top of one's daily eating routine that can cause sodium levels to spike. Over consumption of sodium can have serious health implications such as heart attack, heart disease, kidney damage and high blood pressure.
