Health tidbits
Tuesday, April 29th, 2008Never say that Hack isn’t looking out for you. Consider the following.
Puleeease, ditch the ubiquitous water bottle
You may think that wagging around that water bottle all day long, daintily taking the cap off and swigging away while multi-tasking is both chic and health-conscious. Well, think again. There is no scientific evidence - I repeat - there is no scientific evidence to back up the claim that drinking eight glasses of water a day is healthy.
We all know the claims. Drinking lots of water prevents headaches, removes all those poisons and toxins from the body, improves the function of internal organs and work to reduce the risk of disease. None of these claims are supported by an iota of scientific evidence. There isn’t even a study which supports the notion of the “eight glasses of water a day” claim. Now some studies did look into the claim that lots of water clears the kidneys of sodium and that this might help in reducing hypertension (high blood pressure). But no clinical findings exist which support this claim. Water does help clear urea but urea is not a toxin. There are some “indications” that drinking a lot of water might reduce appetite and control weight gain but again, the jury is still out on this one. More research is required.
“Under normal circumstances,” said Dr. Stanley Goldfarb, professor of medicine at the University of Pennsylvania, “drinking extra water is unncessary. I want to relieve people of the burden of schlepping water bottles around all day long.” Amen.
When you have that pesky nosebleed
Most people, including me, believe that the best way to handle that unexpected nosebleed is to lean the head back and apply pressure to the nose. But, medical experts will tell you that this method is wrong man, dead wrong. Tilting the head back can create complications that you really don’t want to have to deal with - allowing blood into the esophagus, causing choking, diverting blood into the stomach which can lead to irritation or vomiting. So, what the best method?
Sit down, lean forward and keep your head above your heart which lessens the bleeding. Leaning forward also helps to drain the blood from the nose and keeps it from entering the gullet. Then, by using your thumb and index finger, squeeze the soft tissue just above the bridge of your nose for 5 to 10 minutes. A cold compress or ice pack applied to the nose will help. If this fails or if the nose continues to bleed for more than 20 minutes, particularly if the bleed was caused by a blow to the head, no fooling around - get yourself to the ER or your doc.
