What is Insomnia?
Insomnia is a long-term disorder that disrupts an individual's sleep cycle. It makes it very hard for a person to fall asleep. They face major trouble focusing on anything, as they tend to wake up early, feel unrefreshed after sleep or experience daytime fatigue.
Hence, it should be treated as early as possible. If insomnia is not treated on time, it can affect a person's mental well-being.
What are the Types of Insomnia?
Insomnia can be classified into the following types:
-
Acute Insomnia
It refers to a sleep disorder that lasts for a few days or weeks. It can be triggered by stress, anxiety, illness, travel, or major life events. Symptoms usually improve once the cause is resolved.
-
Chronic Insomnia
It is a long-term condition in which a person has trouble sleeping for at least 3 nights a week for 3 months or longer. It may be linked to medical conditions, mental health disorders, poor sleep habits, or lifestyle factors and needs proper treatment.
Note: Insomnia can be classified into several other types based on duration, causes, and sleeping patterns. However, acute insomnia and chronic insomnia are the two most widely recognised types.

Insomnia During Pregnancy

Hormonal changes, physical discomfort, frequent urination, anxiety, and body aches during pregnancy can make it difficult to fall asleep or stay asleep.

Here's what a pregnant woman must follow if diagnosed with insomnia:
