Sleep disorders like insomnia, sleep apnea, and restless leg syndrome can negatively impact mental health by disrupting sleep quality and increasing risks of depression, anxiety, and other mood disorders. Insomnia is linked to higher risks of developing depression and anxiety due to difficulties falling or staying asleep. Sleep apnea causes interrupted breathing during sleep, poor quality sleep, and daytime sleepiness which can impact mood and cognition. Restless leg syndrome makes it hard to fall and stay asleep, leading to poor sleep quality and increased risks of depression and anxiety. While the relationship between sleep disorders and mental health is complex, treatment from a psychiatrist can improve sleep through medications, lifestyle changes, and behavioral therapy.
