Sometimes It helps us to find out the cause for our insomnia - Is it psychological or physiological? If it is physiological, it may be because of a medical condition or just over-exhaustion. They have to be handled accordingly. Most of the times, however, it is psychological. It may be some item of worry or the habit of the constantly chattering mind. If we embark on short-term and long-term remedies to solve this problem, then sooner or later we will succeed. That way a stable base would be laid and the problem cleared forever.
Short-term Remedies: You can try the following. (You may also discover some on your own).
(1) Lie down flat on your back with no pillow for the head. Have some loose cloth below your neck just to give it gentle support so that it is not strained. Have some pillows and loose cloth to support your legs slightly above the level of your back. The forearms may also be supported so that the elbow angle is about 120 deg. Feel absolutely comfortable. In this position, sleep would embrace you within 10 min. However, you cannot sleep in this posture too long. When you wake up, you may go to sleep without much difficulty in your usual bed. Quite often, the above method overcomes even a worried mind. Keep experimenting with it and don’t give up too soon!
(2) Take a cool or warm bath (as appropriate). Do pranayama (breathing exercise) for about 5 to 10 min. (If you are not familiar with it, you may have to approach a teacher.) Then, go to bed. You are likely to go to sleep soon.
(3) Lie down the usual way. Mentally go through the day’s activity in the reverse way – that is, from the latest in the day to the one in the morning. This mental movement should be done without verbalizing. By the time you have gone half way down the line, sleep is likely to have overtaken you. This is because the mind is unaccustomed to going the reverse way.
Long-term Remedies: (1) Consider the insomnia problem as a blessing in disguise. That is, it has come to make you apply yourself to a problem and solve it completely. That application and the going beyond give you trust and confidence in yourself. With that confidence, you are in a better position to solve other problems in life and grow even deeper in your confidence.
(2) Do some research on self-awareness. The chattering mind can give way to a calm and quiet mind. A good read would be the book ‘Stillness Speaks’ by Eckhart Tolle.
(3) Practice Yoga
