Are you sleepy during the day? 
Do you feel generally tired and irritable? 
Do you have problems concentrating or remembering? 

If you answered yes then you may be suffering from insomnia.

Insomnia is a symptom, not a disease. It means that you are having trouble with how much or how well you sleep. This may be caused by difficulties in either falling or staying asleep. Self-reported sleeping problems, dissatisfaction with sleep quality and daytime tiredness are the only defining characteristics of insomnia because it is such an individual experience.

The concept of ‘a good sleep' differs widely from person to person. While the average night's sleep for an adult is around seven or eight hours, some people only need four, while others like up to 10 hours or more. What seems like insomnia to one person might be considered a good sleep by another.

A lack of quality sleep can cause more than just sleepiness. It can cause accidents, affect your relationships, health, weight and mental ability and can make you feel generally "disconnected" from the world.

Over one-third of people experience insomnia from time to time, but only around five per cent need treatment for the condition.

If your sleeplessness is caused by such things as stress, jet lag, a change in sleeping environments, some acute medical illnesses and stimulant medications, you might not have trouble getting your sleep back on track after the event is over. However, if you have trouble sleeping on a regular basis, these tips to managing sleepnessness can help you be well on your way to experiencing healthy, restorative sleep.
