3 Reasons Your Insomnia May Not Be "Insomnia"
Blame apnea, mood, circadian rhythms, lifestyle, or diet:
1. Up to 67% of Insomnia Patients have Sleep Apnea
Research has found that over 67% of Obstructive Sleep Apnea patients also have insomnia. Other studies have found that between 29% and 67% of insomnia patients also have apnea. In other words, there is a lot of overlap between apnea and insomnia. If you only address the insomnia, and the apnea remains untreated, then your sleep quality will be sub-optimal. So, if you really want to tackle insomnia, you have to ask the question of whether apnea may be an issue.
2. About 85% of Chronic Insomnia Patients Have an Underlying Issue
In the scientific sleep community, it is well-known that insomnia often co-occurs with other issues. For example, about 85% of people with chronic insomnia also have mood, circadian rhythm, or other medical issues. It's a bit of a chicken-and-egg situation (i.e., did the insomnia cause the depression, or vice versa?), but the consensus is that the relationship may be bi-directional, meaning each influences the other. This is a very big topic and beyond the scope of this article, but the takeaway here is that there are many factors that can influence insomnia.
