Extracts from the Telegraph:
"Office workers who sit at a desk for eight hours a day and spend more than three hours without stretching double their risk of developing deep vein thrombosis (DVT), scientists have warned.
A study has confirmed that sitting for long periods is as dangerous as flying for raising the risk of potentially fatal blood clots.
Researchers in Southampton and New Zealand questioned 200 patients who were admitted to hospital for either blood clots or heart problems and compared how long each group had remained sitting, both in total and in one period without getting up.
Prof Richard Beasley, from Wellington Hospital, New Zealand, said: "The risk of developing blood clots with prolonged seated immobility is largely unrecognised. However, this study has shown that it is at least as important a factor as long-distance air travel."
"He said more research should be carried out to establish how the workplace environment affects rates of deep vein thrombosis and whether chairs could be designed to encourage a healthy blood flow in the lower limbs.
It is estimated that about one in 2,000 people develop DVT each year in Britain.
Hospital patients who have recently had surgery are at greatest risk. Pregnancy and obesity also increases the risk."Since obesity is a factor in developing DVT, you can reduce your risk of DVT by eating less salt and salty food because this reduces obesity.
Lose weight, reduce your risk of most cancers, high blood pressure, type 2 diabetes, stroke, heart disease, vascular dementia, osteopenia, osteoporosis, hypercholesterolaemia, depression, liver and kidney problems, and improve your health in many other ways without drugs or expense by eating less salt! - Try it! - You will feel so much better!
