It may vary from person to person but normal sleep is typically 7 to 9 hours. That already will give any one a good quality sleep and makes you feel alert during the day. And if you don’t have those sleeping hours then probably you might have a problem and its called insomnia.
Insomnia comes in four major types. Difficulty in falling sleep would be the first type. The second one would be about not having problem falling asleep but have problems staying asleep. Then there is waking up too early and sleep state misperception.
What causes insomnia? Many things but it is important to understand that insomnia is not a disorder but a complaint and the goal is not to find the underlying problem causing the complaint. Sleep disorders like sleep apnea, restless legs, circadian disorders are just some that present themselves as insomnia.
Some causes for insomnia would be medications, herbs and caffeine. Anxiety is also a cause but not really the underlying cause. Mental problems can also be listed a cause.
But no matter what maybe the cause, there is no insomnia that modern alternative medicine like hyperbaric oxygen treatment can not cure. Hyperbaric oxygen treatment with its pressurized 100% oxygen has already been proven to cure insomnia. And what’s more better about it is that you can buy or rent your own hyperbaric chamber so there would be no need to go to a hospital to get the treatment.
Hyperbaric chambers are also easy to operate making it a very product friendly. So while your still thinking about what causes your insomnia, there is no more need to think on what can cure it.
