Sleeping issues may differ from person to person because everybody needs different hours sleep. Insomnia is defined by the quality of your sleep not the number of hours you sleep. Even if you’re spending eight hours a night in bed and you did not have quality sleep you may still be experiencing insomnia.
Insomnia is the most common sleep complaint, it is not a single sleep disorder. It is more accurate to think of insomnia as a symptom of another problem.
The problem causing the insomnia differs from person to person. It could be something as simple as drinking too much caffeine or a more complex issue like an underlying medical condition, feeling overloaded with responsibilities or maybe caused by stress depression.
The good news is that most cases of insomnia can be resolved.
