This means they are immune to the feeling of warmth and relaxation which sends an average person off to sleep within 15 minutes.
Their genes are designed instead to maintain a state of mental alertness.
This makes normal, prolonged sleep impossible so they sleep fitfully, in only short bursts.
Even then, their lack of ‘comfort’ genes may mean they struggle to get comfortable, fussing about the bedding or finding their sleeping position.
There are other so-called insomnia genes — some cause repeated periods of wakefulness in the small hours of the night or at the slightest disturbance, or drive an affected person to leap out of bed raring to start the day at 4am, but leave them exhausted by 4pm.
Until recently, insomnia was considered a purely psychological complaint triggered by stress, grief, or sleep disruption as a result of shift work or jet lag.
But doctors are now unravelling the genetic explanation of why at least one-third of us have intermittent or constant sleep problems.
The Bowen Technique is a natural, drug-free, non-invasive, complementary therapy that can help stress and sleeping problems.
Rather than 'making' the body change, Bowen 'asks' the body to recognise the ailment and make the changes it requires.
During the 30-60 minute treatment, the Bowen practitioner makes small, rolling movements over muscles, tendons, ligaments and soft tissue at precise points on the body, using only the amount of pressure appropriate for that individual.
No hard-tissue manipulation or force is needed or used.
Between each set of moves, the body is allowed to rest for a few minutes, to allow it to absorb the information it has received and initiate the healing process.
Bowen is known for its soothing qualities for physical complaints; however it is an extremely relaxing experience that can have many emotional benefits too.
One client said: “I heartily recommend the Bowen Technique to anyone who wants to remember how it feels to wake up refreshed; looking forward to the new day knowing you can deal with whatever it may bring.
I am now feeling much better, fitter and younger than pre-treatment. Thank you for revitalising me!”
