Almost anyone can suffer from insomnia at some point in their lives, but statistically speaking, there are certain groups that have more than their share of problem sleep.
Women, older people and those that suffer from depression will have insomnia more frequently.
Today research has found that after a woman has a baby, she automatically develops a more acute sense of sound to her baby, enabling her to wake up quickly if she hears a cry or a disturbing noise.
For most women, even when their children have grown up and moved away, women tend to retain this heightened sensitivity to night time noise.
Clinical studies have shown that women, who have never had children, sleep far better and deeper than women who have.
Added to this sensitivity, the constant hormonal changes that every women experiences on a monthly basis.
Some women who suffer from premenstrual syndrome or PMS, may have even a tougher time getting to sleep as their bodies become over run with changing hormones, menstrual cramps or even lower back pain and of course breast tenderness that may make finding a comfortable sleeping position quite difficult.
Menopausal women have even a harder time sleeping as they often have times when they are drenching in night time sweats.
The good news is that by the time women enter the post menopausal phase of life, when all the hot flashes and hormonal swings are finally over, men tent to only then catch up to them in terms of sleeplessness.
In fact, most post menopausal women who don't have insomnia will usually find themselves sleeping longer and better than men of the same age who don't have insomnia.
