Insomnia is a common sleep disorder that affects a significant number of individuals. It is characterized by difficulty falling asleep, staying asleep, or both, leading to inadequate sleep and subsequent daytime fatigue and impairment in daily functioning. Insomnia can be acute, lasting for a short period of time, or chronic, persisting for several weeks or even months.
There are various factors that can contribute to the development of insomnia. One of the primary causes is stress and anxiety. When individuals experience high levels of stress or have racing thoughts, it can interfere with their ability to relax and fall asleep. Additionally, certain medical conditions such as chronic pain, respiratory disorders, or hormonal imbalances can disrupt normal sleep patterns and contribute to insomnia. Other factors include poor sleep hygiene, irregular sleep schedules, excessive consumption of caffeine or alcohol, and certain medications.
