What is insomnia?
Insomnia is when someone is unable to get enough good quality sleep as they are unable to fall asleep or remain asleep.
When someone reacts to a stressor, it is normal to have short-term insomnia for a few weeks or even months but with time sleep quality should improve again. When insomnia goes on longer than this, you may be suffering from chronic insomnia. Studies show that around 1 in 3 adults have insomnia but up to 2 in 3 adults have periods of insomnia during their lifetime.
Ongoing poor sleep can have a negative effect on health. Sleep deprivation can affect your mood making you quick-tempered, irritable, more anxious, or depressed. It can lead to poor concentration and slow reaction times. It can impact hormonal balance which can lead to signals to the brain being disrupted, causing you to eat more as the brain hasn’t recognised that you are full. It can also lead to longer-term physical health problems such as high blood pressure and type 2 diabetes.
