Sports drinks are a bad sport! Many people are in the habit of drinking a sports drink whenever they exercise to re hydrate themselves. Sure they do hydrate Cheap Scott Hartnell Shirt , but unless you have just run an entire marathon, there is practically no benefit to a sports drink over water. The big down side is that they are packed full of sugar, so take a look at how much sugar you are taking in.
A bottle of Powerade has 36grams of sugar in it, almost as much as a can of coke. If you have a Powerade 3 days a week that equates to 5.6kg of pure sugar! It hits the wallet hard too Cheap Sergei Bobrovsky Shirt , at say $3.50 a bottle that?s $546 year. Compared to water which is sugar free, costs nothing and does the same job, a sports drink defies the point of drinking it for health benefits.
Water is the best option for hydration during exercise in fact you need 4 6 ounces for every 15 minutes you exercise. Sugar rich sports drinks actually slows down hydration because the cells absorb the sugar first, which reduces the rate that the water is absorbed into the cells for re hydration. For this reason Cheap Artemi Panarin Shirt , juices and carbonated soft drinks are not good to drink, either. It is advised that you avoid any drinks that are high in sugar or caffeine.
While the sugars and caffeine offer an energy boost, they are not nutritionally good for you and many contain as many calories as you are burning during your exercise routine, which defeats the purpose. In fact Cheap Seth Jones Shirt , energy and sports drinks slow re hydration, you may drink a lot more of them than is necessary and still feel thirsty. You certainly don?t need the extra calories they provide.
That?s not to say that there aren?t some of the sugar free sports drinks that might be better for you, and now they are making vitamin enhanced or flavored bottled water, making it more likely that you will drink enough to get properly hydrated Cheap Josh Anderson Jersey , without the added calories, sugar and caffeine. The only thing is that to get re hydrated properly, there is no replacement for the free, calorie less drinking water that comes out of your kitchen tap.
During an exercise routine Cheap Nick Foligno Jersey , it is re hydration that is most important, not nutrition. While juice has vitamins, minerals and electrolytes, which are good for you Cheap David Savard Jersey , it is more like a food item and it isn?t a great thirst quencher. Even coffee and tea are considered diuretics which pull more water out of your bloodstream, even as the digestive system is putting it back in. Adding milk or sugar only makes this process worse.
Of course alcoholic beverages can have the opposite effect and actually make you thirstier. Any kind of diet carbonated beverages are high in sodium, which has the same ?drying? effect on your cells. If you have ever drunk these on a hot day to quench thirst, you may have noticed that the more you drink Cheap Oliver Bjorkstrand Jersey , the thirstier you get.
Drinking water is the best remedy for quenching thirst during your workout. Save the sports drinks for running a marathon, where you need the boost of energy from the sugar. You will still need to be sure you drink plenty of water, though.

WASHINGTON, July 28 (Xinhua) -- U.S. astronauts who flew the Apollo moon-landing missions in the 1960s and 1970s are experiencing higher rates of heart problems that are thought to be caused by their exposure to deep space radiation, new research said Thursday.
Apollo astronauts are the only humans that have traveled beyond Earth's protective geomagnetic field, while other manned spaceflight has taken place exclusively in low Earth orbit, where such protection against space radiation is still present.
In the new study, researchers from the Florida State University compared the cause of death for seven Apollo lunar astronauts to 35 astronauts who flew only in low Earth orbit and 35 astronauts who never flew orbital missions in space.
They found that 43 percent of deceased Apollo astronauts died from a cardiovascular problem. That is four to five times higher than non-flight astronauts and astronauts who have traveled in low Earth orbit.
""We know very little about the effects of deep space radiation on human health, particularly on the cardiovascular system,"" Professor Michael Delp of the Florida State University, who led the study, said in a statement.
""This gives us the first glimpse into its adverse effects on humans,"" Delp said.
To test a possible mechanistic basis for these findings, the researchers exposed mice to the type of radiation that Apollo astronauts would have experienced.
After six months -- the equivalent of 20 human years -- the mice demonstrated an impairment of arteries that is known to lead to the development of atherosclerotic cardiovascular disease in humans.
""What the mouse data show is that deep space radiation is harmful to vascular health,"" Delp said.
The findings were published in the British journal Scientific Reports.
The Apollo program, most notable for landing men on the moon, ran from 1961 to 1972. The program included 11 manned flights between 1968 and 1972, nine of which flew beyond Earth's orbit into deep space.
Of the 24 men who flew into deep space on the Apollo lunar missions, eight have died and seven were included in the study. The eighth, Edgar Mitchell, died after the data analysis had been completed.
