Maintaining the fine balance of our circadian cycles can often be somewhat delicate, and it can be disrupted or modified quickly, although normally it is able to reset itself within a few days, if the disruption doesn't persist for too long of a period of time. As an example, if you take a long plane flight, you may temporarily experience jet lag because the time change causes a sudden disruption of your internal body clock. Likely, you will only suffer from the effects of jet lag for a couple of days before your cycles reset themselves and the jet lag goes away.
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 a large number of 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 serves a primary role in controlling the circadian cycle, and helps to keep it in sync. When our rhythms are out of sync, often times the pineal gland just isn't making enough melatonin for normal functioning. 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 at bedtime, but then find themselves waking regularly throughout the night, and, many times, simply are 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 sufficient levels for the remainder of the night, they rapidly drop to levels which usually occur during waking hours. If this is happening to you and you wake up during the night, you may find that you have insufficient melatonin levels to allow 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 its 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.
