Causes of sleep problems in EDS and HSD
Most people with EDS or HSD have chronic pain. Pain and other symptoms may make it difficult to get comfortable enough to fall asleep. People with EDS or HSD may also wake up during the night due to pain, joint instability, and other symptoms. Arousals and awakenings during the night can interfere with the sleep cycle and prevent a person from getting deep sleep. This means that a person may not feel well-rested even after sleeping for an appropriate amount of time.
People with EDS or HSD may also experience chronic fatigue. Chronic fatigue prevents a person from feeling well-rested which can disrupt healthy activity and sleeping patterns. Fatigue can also worsen pain and other symptoms that contribute to poor sleep.
Many people with EDS or HSD have other related health conditions, such as a type of dysautonomia or mast cell activation syndrome. EDS and HSD are also associated with higher rates of psychiatric disorders, including anxiety disorders, mood disorders, and attention-deficit/hyperactivity disorder (ADHD). These conditions can have their own effects on sleeping patterns. Medications taken to treat the symptoms of EDS, HSD, and related conditions can also affect sleep and may contribute to daytime tiredness.
Some people with EDS or HSD have breathing issues during sleep, known as sleep-disordered breathing (SDB). There are different types of SDB which cause symptoms such as:
- Snoring
- Unrefreshing sleep
- Daytime tiredness
Some studies show higher rates of obstructive sleep apnea (OSA) in people with certain types of EDS. Obstructive sleep apnea is a type of SDB in which breathing stops repeatedly during sleep due to a partial or complete blockage of the airway. More research is needed to better understand the relationship between SDB and EDS. Currently, SDB has only been studied in people with hypermobile EDS, classical EDS, and vascular EDS.
