Insomnia is one of the most common sleep disorders, affecting millions of people worldwide. It can make it difficult to fall asleep, stay asleep, or wake up feeling refreshed. While occasional sleeplessness is normal, persistent insomnia can impact your physical health, emotional well-being, and daily performance.
Understanding the causes, symptoms, and available treatment options can help individuals take the right steps toward improving their sleep and overall quality of life.

Insomnia is a sleep disorder characterized by difficulty falling asleep, staying asleep, or waking up too early and being unable to return to sleep. It may be short-term (acute) or long-term (chronic), depending on how long the symptoms persist.
- Acute Insomnia: Lasts from a few days to several weeks and is often triggered by stress or life events.
- Chronic Insomnia: Occurs at least three nights a week for three months or longer and may require professional evaluation and treatment.

Medical Conditions
Certain health conditions such as chronic pain, asthma, acid reflux, thyroid disorders, and neurological conditions can contribute to insomnia.

Depression, anxiety disorders, and other mental health conditions are commonly associated with sleep difficulties.
Medications
