  • Female gender affected most; Women tend to be the victims of insomnia more often than their male counterparts. This is partially due to the fact that hormonal changes which are intrinsic to females can bring about this particular condition. These changes may include PMS, menstruation, pregnancy and menopause.

What are the Symptoms of Insomnia?

Insomnia is not defined by the number of hours of sleep a person gets or how long it takes to fall asleep. Individuals vary normally in their need for, and their satisfaction with, sleep. Insomnia may cause problems during the day, such as tiredness, a lack of energy, difficulty concentrating, and irritability.

Insomnia patients generally complain of:

  • Inadequate or poor-quality sleep.
  • Difficulty falling asleep; early wakening, waking frequently during the night, un-refreshing sleep, or a combination of these.
  • Waking up frequently during the night with difficulty returning to sleep.
  • Waking up too early in the morning.
  • Persons without adequate sleep can experience tiredness, lack of energy, and concentration problems.
