The cool, glistening waters of public pools are certainly seductive on a hot summer day. But if they’re not properly maintained and treated, these public pools spread germs that can cause unpleasant illnesses and ruin the fun. Here’s what you need to know to stay safe (and cool) in a public pool.
“Another One Bites the Dust” works too, but you might not want to be caught humming it while doing CPR. 😉
You could teach swimmers to communicate their status over the water, the same way scuba divers do under it. If I point at a kid, they need to make a fist and tap the top of their head with it. That’s the “I’m okay” sign. If I don’t get a response, I need to go get you. That said, I’ve swam in water where visibility is 6 ft at most, with goggles.
…Many reports have observed that heavier patients appear more likely to come down with infections during a hospital stay, acquire weaker protection from vaccinations and, as with River, suffer more complications from the flu.
Weight alone may not be the entire explanation. A tantalizing line of evidence suggests that unhealthful foods — fatty, salty, sugary, processed foods — may disrupt the body’s defenses in a way that promotes inflammation, infection, autoimmune diseases and even illnesses like cancer.
[Former pro Ben] Day believes that every single athlete undergoing a training cycle needs to better understand when to push through fatigue, illness or injury and when they should rest and recover. Below, Day discusses some guidelines in making the right decisions.
For content from a cycling website, the only thing that applies to cycling is measuring power via a power meter (in the hub, cranks, or pedals). Which lead me to wonder if anyone has implemented a power meter in running shoes… Someone has, and DCRainmaker has a review! If you haven’t read DC Rainmaker stuff before, it’s incredibly detailed and insightful.
You’ve probably heard it a zillion times: take some vitamin C if you feel a cold coming on, and chase away illness with a gallon of orange juice. Even though we know there’s no cure for the common cold, many of us still believe in the sweet, orange elixir and don’t even question what the makers of the stuff guarantee: an 8 oz. glass delivers “100% of the vitamin C” needed to “maintain a healthy immune system.”
Science-ish looked at high-quality studies on the subject of vitamin C and sickness, starting with this recent Cochrane systematic review (the highest form of evidence) on the supplement for prevention and treatment of the common cold. The lead author, Dr. Harri Hemilä, of the department of public health at the University of Helsinki, told Science-ish he has spent much of his career exploring this very question—with some interesting results.
…there is good evidence it has benefits for one specific group of people: those who undertake really intense physical activity such as marathon runners. For them, vitamin C supplementation decreases the incidence of colds by half. These findings, though, do not hold up for ordinary people, Dr. Hemilä emphasized.
Biologists have been mixing the DNA of different animals since the 1970s, but the idea of injecting the genes of animals into humans remains taboo. Called transgenics, it’s a practice that could cure illness in the future — and eventually reshape our species. Here’s what you need to know about it.
