In individuals with insomnia, about 40% also have a concurrent mental health disorder, compared to a 15% rate in individuals with normal sleep.

Q: How does sleep deprivation affect emotional regulation?

Sleep deprivation impairs the ability to regulate emotions, leading to increased negative interpretation of stimuli and heightened perception of pain. Acute sleep deprivation can also lead to frontal lobe dysfunction and cognitive impairments.

Q: What is the relationship between sleep disturbance and anxiety?
