Myths about Insomnia and Depression

Myth: Insomnia is why I’m irritable and tired.

Fact: While it is true that lack of sleep can cause irritability and tiredness, insomnia may arise due to other reasons. While trouble sleeping is certainly problematic, irritability is more likely to be an issue noticed by friends, family, and coworkers.

When someone is not sleeping well, they may still feel irritable or tired even if they believe they slept through the night. In other words, long-term irritability and tiredness is linked to a cause underlying the simple inability to sleep soundly. It is important to evaluate if insomnia led to irritability and fatigue or if something else, such as stress, health issues or new medication came first and led to the insomnia. An evaluation for a possible mood disorder should also be part of the doctor’s evaluation.
