There are several ways of natural sleep aids to help fall asleep. All depend on the person to do or not to do.
A helpful technique is to relax your body one part at a time. So you could relax your feet, your lower legs, upper legs, moving up from your lower belly up to your chest. In other words, do some sort of stretching up and inhale and exhale exercises.Of course, guided relaxation methods can help, imagining yourself in the country, the beach, or whatever is most soothing to you.If you have annoying thoughts or personal issues that run through your mind when you are trying to sleep, you might have to deal with those issues first. You might want to talk to a counselor or therapist about that. I suggest avoiding prescription sleeping pills unless nothing else helps.
There are herbs that are helpful for sleep, eg, valerian root, kava kava, chamomile, hops, passion flower, skullcap. If you get the real herbs, you can make teas out of them. Otherwise get the herbs in capsule form. You can try a single herb or herbal combinations. Probably, valerian root and kava kava are the best.You can also try trytophan, 5-HTP and melatonin (1-2 mg). I would not take melatonin for over a month. It is a hormone produced by the pineal gland. If you take too much, your pineal gland might get "lazy" and produce less melatonin naturally. Life Extension and TwinLabs are probably the best brands, in that order.
The last but not least the use of Valerian, homoeopathic remedy Ignatia, Bachs Remedy all available in health food stores also best for natural sleep aids to help fall asleep.
Cheers.
