Scientific explanation about insomnia

Answer 1

Insomnia is a sleep disorder characterized by difficulty falling asleep, staying asleep, or waking up too early, leading to daytime impairment. It can be caused by various factors, including stress, anxiety, medical conditions, and certain medications. Physiologically, insomnia can disrupt the body's circadian rhythms and affect the production of sleep-regulating hormones like melatonin. Chronic insomnia may also impact cognitive function and emotional well-being, creating a cycle that perpetuates sleep disturbances.
