There is generally a common element which connects the various types of insomnia - our internal body clock (circadian cycle). The circadian rhythm is an automated function of our bodies. If our circadian rhythm gets out of sync, our waking and sleeping cycles will be disrupted.
Our circadian cycles are somewhat delicate and can be disrupted quickly, although normally it will reset within a few days. As an example, if you take a long flight, you feel jetlag because the time change disrupts your internal clock. You will probably only suffer from jetlag for a couple of days before your cycles reset and the jetlag disappears.
However, it is much more difficult to reset the circadian rhythm when it has been out of sync for extended periods of time due to conditions like depression, stress, anxiety, and chronic pain. This can be the root cause of most cases of chronic insomnia. To successfully treat chronic insomnia the circadian rhythm must first be reset.
Our circadian rhythm is regulated by a hormone produced in the pineal gland which is called melatonin. Melatonin controls the circadian cycle helps to keep it in sync. When our rhythms are out of sync, often times the pineal gland isn't making enough melatonin. The pineal gland is very sensitive to changes in our bodies and it can restrict production of melatonin when there are certain changes occurring within the body.
Many find that they can fall asleep readily but then wake regularly throughout the night, often not able to fall back to sleep. This is generally caused by the pineal gland producing just enough melatonin to induce you to fall asleep, but instead of melatonin levels remaining at peak level for the remainder of the night, they rapidly lower to a waking level. If this is happening to you and you wake up during the night, you may find that you have insufficient melatonin levels to induce you to fall back to sleep.
On the other hand some may find it almost impossible to fall asleep and spend the majority of the night tossing and turning, and eventually falling asleep in the early hours of the morning only to have to get up soon afterwards. In this case, the melantonin levels produced by the pineal gland never get to the peak that they should.
The best way to raise your melatonin levels is to stimulate your body to make more of it’s own melatonin. The pineal gland is general sensitive to electromagnetic fields. When an electromagnetic field is placed near the head of the pineal gland it is stimulated and it begins to produce more melatonin. Over a period of a week or so, your body’s melatonin levels should increase to a normal range. Once the body's melatonin levels have reached a normal level, the circadian rhythm begins to reset and insomnia will eventually end.
Many of those who suffer from insomnia could achieve excellent results by using magnets in their pillow at night. Research has shown that magnetic pillow pads can relieve jetlag in crews of long flights and there have been tests done regarding those who suffer from chronic insomnia. The magnetic therapy pillow pad should be placed inside the pillow case permanently in order to help prevent the circadian rhythm from becoming out of sync again.
