An expedition to Mount Everest by Italian researchers has shown for the first time that blood pressure monitored over a 24-hour period rises progressively as people climb to higher altitudes. The researchers also found that a drug used for lowering blood pressure, called telmisartan, was effective in counteracting the effects of altitude up to 3,400 meters.

In states where it is legal to use medical marijuana to manage chronic pain and other conditions, the annual number of deaths from prescription drug overdose is 25 percent lower than in states where medical marijuana remains illegal, new research suggests.
A study suggests that, although cardiovascular disease (CVD) causes twice as many deaths as cancer in some countries, in 10– Belgium, Denmark, France, Luxembourg, The Netherlands, Portugal, Slovenia, Spain, San Marino and Israel– cancer has now overtaken it as the leading cause of death in men. Denmark has also become the first country where cancer has overtaken CVD as the leading cause of death in women.
Pediatricians have a prescription for schools: later start times for teens. Delaying the start of the school day until at least 8:30 a.m. would help curb their lack of sleep, which has been linked with poor health, bad grades, car crashes and other problems.

Just how large are the health benefits of cleaner air in comparison to the costs of reducing carbon emissions? Researchers looked at three policies achieving the same reductions in the U.S., and found that the savings on health care spending and other costs related to illness can be big— in some cases, more than 10 times the cost of policy implementation.

Under the right scenario, exporting U.S. coal to power plants in South Korea could lead to a 21 percent drop in greenhouse gas emissions compared to burning the fossil fuel at plants in the U.S. Despite the large amount of emissions produced by shipping the coal, total emissions would drop because of the superior energy efficiency of South Korea’s newer coal-fired power plants.
Practicing hatha yoga three times a week for eight weeks improved sedentary older adults’ performance on cognitive tasks that are relevant to everyday life, researchers report.
