Insomnia
Insomnia is difficulty falling asleep or staying asleep. Insomnia can cause one to feel fatigued during the day or have trouble focusing on tasks. Many factors can contribute to insomnia, such as stress, poor sleep hygiene, stimulants, alcohol, and shift work. Insomnia can also be a side effect of other underlying disorders such as depression or psychiatric problems, breathing disorders, leg kicks during sleep, or even gastroesophageal reflux. Insomnia can be treated with a variety of behavioural changes, relaxation techniques, or even short-term sleeping medication. Any underlying sleep disorder should be eliminated as a potential cause of the insomnia.
