Medical notes this week…
How safe is vaping? A new study in the journal Environmental Health Perspectives says it’s not. Researchers say people using e-cigarettes are likely to inhale significant amounts of lead, chromium, manganese and other toxic metals. The problem apparently isn’t in the e-liquids the devices use. It’s the heating coils that leak heavy metals. Scientists say that nearly half of the aerosol vapers tested had lead concentrations higher than health limits defined by the epa.
A lot of people, including doctors, mistakenly judge a person’s health by their weight. But a new study in the journal BMC Obesity finds that it’s very possible to be healthy and fit even if you’re obese. Scientists tested more than 800 people and found that more than 40 percent of those with mild obesity still had high fitness levels. Twenty-five percent of those with moderate obesity had high fitness and 11 percent of those with severe obesity still had high fitness. Researchers say it takes a lot less physical activity to improve health than to lose weight.
And finally… scientists have determined that money can, indeed, buy happiness but it takes the right amount of cash. Too much can be as bad as too little. A global study in the journal Nature Human Behavior finds that 60-to-95 thousand dollars per year is the ideal income for a single person. Researchers say income greater than that is likely to prompt the pursuit of more material gains and social comparisons, which make people less happy.
