Insomnia
Insomnia is a most common sleep disorder that makes it difficult for a person to fall asleep, stay asleep, or cause to wake up too early and be unable to sleep again. One can feel exhaustion inspite of a full night's sleep. Insomnia can lead to depletion of your energy, health, attitude, work performance, and overall quality of living.
Sleep problems can be intermittent or persistent.
- A short-term sleep problem is often associated with short-term stress, such as stressful life events(accidents, loss of family members, divorce), jet lag, and changes in sleeping environments. This type of short-term insomnia can last for several days or weeks. It usually improves within a month.
- A chronic sleep problem is persistent. It is known as chronic insomnia. It is frequently a symptom of another medical condition, such as depression or chronic pain. Chronic insomnia is comparatively less common than short-term sleep problems.

Causes of insomnia
- We all have different sleeping patterns. A healthy individual requires 7 to 8 hours of sleep. People can have acute insomnia due to certain lifestyle modifications or medications. The condition can be treated easily with the help of doctors.
- If the insomnia is not going away even after months, then it is probably due to chronic disorders. It can be due to stress or stress-related life issues.
- Different types of medications, alcohol abuse, and smoking are the leading causes of insomnia.
Although there are many conditions responsible for insomnia, it is yet treatable. Simple alterations in the routine can be beneficial.

The diagnosis of insomnia may include the following:

- Sleep study(Polysomnography)- If the cause of your insomnia is unknown, or you are having other sleep problems such as restless legs syndrome or sleep apnea, you might need to spend the night at a sleep center.
