A new study of 1,200 people showed that the average Australian adult gets less than seven hours sleep a night, below the seven to eight hours recommended by sleep experts.
A study by Columbia University, found people who slept four hours or less per night were 73% more likely to be overweight or obese. Also, people who habitually slept for five hours had 15% more ghrelin, a hormone which increases feelings of hunger, than those who slept for eight hours. Those who slept for less time were also found to have 15% less leptin, a hormone which suppresses appetite. "These differences are likely to increase appetite and therefore contribute to obesity" Dr Taheri states. The subjects in the study also tended to eat more sweet and starchy foods when sleep was cut short.
While research continues, sleep still remains one of the body's most mysterious processes. We do know that sleep is absolutely necessary for survival and even occasional sleeping problems can make daily life feel more stressful or cause you to be less productive. Sleep loss also affects growth hormone secretion that is linked to obesity and impairs the body's ability to use insulin, which can lead to the onset of diabetes. It is paramount that we discover more about this activity where we spend a third of our lives - sleeping.
There are prescriptions and non-prescription drugs, herbs, remedies, technologies, etc that may help you get a good night's sleep. Some work for some and not for others.
Here are some tips you can try at home tonight. These tips are intended for the average adult, but not necessarily for children or persons experiencing medical problems:
Think of a hammock - you're up off the ground, wrapped in a cocoon of comfort, swaying gently in the open air. The sun is warm on your face and there's a cool breeze blowing you back and forth. This visualisation helps you "see" what the reward for sleeping will be, getting you more in the mood to sleep. Visualisation has proved helpful in developing the appropriate brain wave patterns for sleep.
Has a calming effect on the nervous system. It is part of bones and cells, especially the smooth cells of arteries and assists in the absorption of calcium and potassium. Over 300 enzymes in our body need magnesium to function properly. It is so important, that the brain stores a "safety supply" to have in the event of a drop in the magnesium reserves.
Grind fresh nutmeg and serve it with warm low fat milk and a touch of honey. Milk is naturally high in calcium and rich in tryptophan; together they can be a powerful tranquilizer (and very delicious).
In the Eastern World, a hot foot bath is a traditional remedy; it draws blood from the brain to calm a racing mind. Try soaking your feet in a hot bath with a cupful of Epsom salts and a few drops of lavender essential oil, which will soothe you. Your feet absorb the magnesium from the Epsom salts to relax you further.
Soothes down the digestive system and helps bring about deeper relaxation. Lie on your back and place your hand on your belly button. Begin to make small circles in a clockwise direction as you gently glide your hand over your stomach. Let your circles gradually become bigger and bigger. When your circles reach the outside of your stomach, gradually reduce their size until you are back at your belly button again. Reverse the direction; repeat the whole series with your other hand and do this several times. Doing this with lavender oil can create an even more relaxing experience.
The brain works like a tape player - with one main auditory loop that processes words. If you fill that loop with an interesting book, there's no room for your own worrisome internal narrative. Especially helpful for those who have continuous thoughts running through their heads.
Take a deep breath in then slowly release out - focussing on your breathing causes your mind to get distracted from your worries and focussed on your breathing. Doing this for a few minutes can relax your mind and help you get a more peaceful sleep.
Sleep experts suggest refraining from doing work, watching television, or being on the computer at least an hour before bed time. This allows your brain to start to 'wind down'.
