The science: A 2009 study of people in Switzerland, published in the journal Circulation, found that those living at high altitudes had a 22 per cent lower risk of dying of coronary heart disease.
Why it helps: Nobody’s quite sure. Scientists say the extra UVA exposure, which means more vitamin D, could be one benefit. Measurement of vitamin D levels in various population samples in Australia and New Zealand has revealed an unexpectedly high prevalence of vitamin D deficiency – a condition that may lead to bone disorders and heart disease – among children, adults, the elderly and other vulnerable groups.
Your move: Most people can benefit from taking 1000 International Units of vitamin D daily, so eat more D-rich foods – salmon, tuna and mackerel are good bets. Also, look to soak up a little sun each day outside of 10am-3pm– up to 10 minutes in the warmer months and half an hour in winter.
