What is insomnia

Insomnia is a persistent and distressing sleep disorder affecting a third of the UK population. Women are up to 2 times more likely to be affected by insomnia, but the occurrence increases in both men and women with age.

Insomnia that lasts between 1-3 weeks is referred to as being ‘mild’, ‘short- term’ or ‘transient’. If persistent- lasting for more than 4 weeks, it is referred to as ‘chronic Insomnia’. Chronic insomnia is less common but affects a staggering 10% of the population.

Insomnia may also be referred to as being ‘primary’ or ‘secondary’. Primary insomnia has no obvious cause. Secondary (or co-morbid) insomnia is caused by or associated with another medical or psychiatric health condition, or an environmental factor and accounts for 15-20% of chronic insomnia.
