Blog Post: Insomnia in the Middle Ages: A Historical Analysis
Insomnia is a common sleep disorder that affects millions of people around the world. But did you know that this condition has been around for centuries, even during the Middle Ages? In this blog post, we will take a closer look at how insomnia was perceived and treated during this period in history.
Insomnia in the Middle Ages was not simply seen as a sleep disorder, but rather as a symptom of a larger issue. It was believed that insomnia was caused by an imbalance in the body’s humors, or bodily fluids. This theory came from the ancient Greek physician Hippocrates and was widely accepted during the Middle Ages.
One of the main causes of insomnia during this time was believed to be an excess of black bile, one of the four humors. Black bile was thought to be responsible for melancholy and was associated with insomnia, among other conditions. This belief led to treatments that focused on restoring balance to the humors, such as bloodletting, purging, and herbal remedies.
Another factor that contributed to insomnia in the Middle Ages was the environment in which people lived. Many people during this time lived in crowded and unsanitary conditions, which could lead to discomfort and disrupted sleep. Additionally, the use of candles and oil lamps for light during the night may have also contributed to sleep disturbances.
Insomnia was also linked to spiritual and religious beliefs during the Middle Ages. It was believed that if someone was unable to sleep, it was a sign of their sins and the need for repentance. This belief led to the practice of praying for sleep or seeking forgiveness from a religious figure.

Interestingly, some of the treatments for insomnia during the Middle Ages are still used today. For example, herbal remedies such as chamomile and valerian were commonly used to promote relaxation and sleep. However, other treatments, such as bloodletting and purging, have been proven to be ineffective and even harmful.
In addition to physical and spiritual causes, insomnia in the Middle Ages was also attributed to psychological factors. Mental disorders were often linked to sleep disturbances, and people who suffered from insomnia were thought to have an imbalance in their minds. This belief led to the use of various treatments, including prayer, exorcism, and even torture, to try and cure insomnia.
Women, in particular, were thought to be more susceptible to insomnia due to their supposedly weaker physical and mental constitution. This led to the belief that women needed more sleep than men and that a lack of sleep could lead to hysteria or other mental disorders.
Despite the various beliefs and treatments surrounding insomnia in the Middle Ages, there were also some early understandings of the importance of sleep. The 12th-century physician, Hildegard of Bingen, wrote about the importance of sleep for maintaining good health and even recommended certain foods and herbs to improve sleep.
In addition to the cultural and medical beliefs surrounding insomnia, there were also societal implications for those who suffered from this condition. In a time when productivity and efficiency were highly valued, individuals with insomnia were seen as lazy or weak. They were often shunned and faced discrimination from their peers.
In summary, insomnia in the Middle Ages was perceived and treated differently than it is today. It was seen as a symptom of a larger issue and was linked to a variety of physical, spiritual, and psychological causes. While some treatments were effective and still used today, others were based on false beliefs and could be harmful. The societal implications for those who suffered from insomnia also added to the already burdensome condition.
Despite the advancements in our understanding and treatment of insomnia, the impact of this condition on individuals and society remains significant. It is important to continue researching and finding effective treatments for this sleep disorder in order to improve the quality of life for those who suffer from it.
