How to test if you have good posture

Half an hour of muscle strengthening activity could help reduce the risk of dying from any cause by as much as a fifth.

Counting sheep is the age old method of falling to sleep, but does it really work? Those finding hard to sleep often seek distraction and some distractions work better than others, a team at Oxford University has found.   Researchers have discovered that picturing an engaging scene takes up more brain space than the same old sheep.  In addition it is easier to focus on an engaging scene because its way more interesting that sheep. Harvey and her colleague Suzanna Payne asked 50 insomniacs to try different distraction techniques on certain nights, to see which helped them fall asleep more quickly. One group conjured up a tranquil and relaxing scene such as a waterfall or being on holiday, while a second were asked to think of a distraction such as counting sheep. A third group were left to their own devices. On average, those picturing a relaxing scene fell asleep over 20 minutes earlier than on nights they didn’t try the technique. But both the sheep-counters and the controls took slightly longer than normal to fall asleep on the nights of the experiment.  The researches concluded that counting sheep is just too mundane to effectively keep worries away. If you find it difficult to conjure up vivid visulisations, aromatherapy may help.  A few drops of lavendar, chamomile or neroli essential oils may assist you to relax and unwide, and counjure up tranquil springtime fields.

In part 1, I looked at the impact of sitting on your muscles, but what happens in the rest of your body? Leg Disorders We are all familiar with the risk of deep vein thrombosis (DVT) if we take long flights.  This is because sitting for long periods of time slows blood circulation, which causes fluid to pool in legs.  This creates problems ranging from swollen ankles, varicose beings to dangerous blood clots. Soft Bones Osteoporosis is a disease marked by reduced bone strength leading to an increased risk of fractures, or broken bones. Bone strength has two main features: bone mass (amount of bone) and bone quality.  Osteoporosis is often called a “silent disease” because it usually progresses without any symptoms until a fracture occurs or one or more vertebrae (bones in the spine) collapse.   Weight-bearing activities such as walking and running stimulate hip and lower-body bones to grow thicker, denser and stronger.  Medical researchers partially attribute the recent surge in cases of osteoporosis to lack of activity.

• diabetes
• gallstones
