Steps to Battle Insomnia
Sometimes I have difficulty in sleeping right away. There are just times when I feel so sleepy and I really wanted to sleep yet I just can’t seem to fall asleep. This problem of not falling asleep is what people call insomia. Insomia as defined on wikipedia.com is a sleeping disorder characterized by persistent difficulty falling asleep or staying asleep despite the opportunity. It is typically followed by functional impairment while awake. Insomniacs have been known to complain about being unable to close their eyes or "rest their mind" for more than a few minutes at a time. Both organic and non-organic insomnia constitute a sleep disorder.
So, here are some tips I got from yahoo on how to battle insomnia and get a good night sleep.
* Acknowledge your stressors. Consider transferring that list of items swirling around in your head at night onto a sheet of paper. This will help you feel as if you’ve gotten started with your tasks and let you get some rest.
* Exercise regularly. It may seem counterintuitive, but upping your level of activity during the evening, when you think you’re wiped out, will help you to gain a second wind and probably to sleep better when you do retire.
* Avoid caffeine after mid-day. Be wary, too, of sodas and teas, which often contain caffeine as well.
* Go to bed when you’re tired. Don’t spend time staring at the ceiling and worrying about how you simply must get some sleep. Get up, do something relaxing in another room, and return to bed when you’re ready.
* Learn relaxation techniques. Consciously attend to your breathing; imagine being in your favorite place (think: "Calgon, take me away!"); relax your muscles, scanning your body from head to toe – Pilates and yoga classes often teach these skills.
* Maintain a routine. Changing your sleep schedule dramatically on Friday and Saturday nights can lead to a shift in your circadian rhythm that carries into the following week.
* Consider melatonin. This hormone is a natural sleep aid. It appears to work particularly well for those who have trouble staying asleep, even though they may easily fall asleep. A dose of 0.3 mg nightly is recommended.
I have not yet tested these ways but I think these would really work. Hope it helps those insomniatic people out there struggling from this disorder. Fortunately for me, I just experience it once in a while.
