Insomnia is one of the most common sleep disorders, but it is often confused with the idea of having difficulty sleeping.
However, insomnia is a condition that affects not only night-time sleep but can also affect daytime performance. This is because insomnia can affect an individual’s energy levels, concentration, and emotional balance.
Insomnia is characterised by an inability to fall asleep, an inability to stay asleep, and waking up too early. This condition affects an individual even if they have enough time and the right environment to sleep. This condition may affect an individual’s physical and emotional health. Insomnia is a very common condition in the UK.
Studies have shown that up to 1 out of every 3 UK adults suffer from insomnia. In addition, about 10 to 14% may be suffering from chronic insomnia.
Having knowledge about what insomnia is, the various insomnia symptoms, and the causes of insomnia is important and one of the key steps towards improving sleep and restoring it.
