Not Sleeping? Not Sure Why?
Sleep struggles usually come from one of three places: the mind, the body, or breathing. Sometimes it's obvious. Sometimes it's not.
If you're tired of guessing and would like help figuring out where your sleep issues are actually coming from, book a free Sleep Clarity Call:
The other day, I had a discovery call with a 21-year-old woman who was engaged and desperately looking for answers. She originally came to me because of her sleep, but as we spoke, it became clear that sleep was only one piece of a much bigger puzzle.
She was dealing with gastrointestinal issues, frequent migraines, and a growing list of foods that seemed to trigger reactions. Her doctor believed she had MCAS (Mast Cell Activation Syndrome), and from what she described, that explanation seemed to make sense. When your body is producing a wide range of symptoms that don't appear to be connected, finally having a possible explanation can feel like a huge relief.
As a sleep coach, I often explain that sleep issues usually come from one of three places: the mind, the body, or breathing. Sometimes the cause is obvious. Other times, it's a combination of two or even all three interacting with each other. In this young woman's case, it seemed quite possible that the body was playing a significant role in both her health challenges and her sleep difficulties.
If you want to understand this framework more deeply, I wrote about it here:https://www.chevymermelsteinsleepcoach.org/post/are-my-sleep-issues-coming-from-my-mind-or-my-body-understanding-the-mind-body-connection
As we continued talking, she mentioned that she had been doing her own research. Like many people today, she had turned to AI to better understand what was happening. I use AI myself and find it incredibly helpful. It can organize information quickly and point us in directions we might not have considered.
The problem wasn't that she had used AI. The problem was what happened next.
After learning more about MCAS, she was told that people with MCAS can also have SIBO. Suddenly, what had started as one possible explanation became two. Now she wasn't only trying to understand MCAS. She was trying to understand SIBO as well.
As I listened, I realized that this is becoming a very common problem. Many people aren't suffering from a lack of information. They are suffering from an overload of it.
Years ago, if you developed a health issue, you might have spoken to your doctor, perhaps gotten a second opinion, and then decided on a plan. Today, before a person even walks into a practitioner's office, they may have spent hours reading articles, watching videos, scrolling through social media, listening to podcasts, and asking AI questions. By the time they arrive, they have collected a dozen different theories, each one sounding convincing.
The challenge is that information and clarity are not the same thing.
In fact, the more information we gather, the harder it can become to identify what actually applies to us.
This is especially true when it comes to sleep.
Over the years, I've found that most sleep struggles can be traced back to three main areas: the mind, the body, and breathing. Understanding which of these is involved is often far more valuable than collecting another theory about what might be wrong.
When Sleep Problems Come From the Mind
This is often the easiest category to recognize.
You get into bed exhausted, but your mind decides it's the perfect time to replay the conversation you had at lunch, worry about tomorrow's meeting, think about your finances, or calculate how many hours of sleep you'll get if you fall asleep right now.
Many of my clients don't struggle because they aren't tired. They struggle because their minds won't let go.
Sometimes it's anxiety. Sometimes it's stress. Sometimes it's the pressure to sleep.
Ironically, the more desperately someone wants sleep, the more difficult it can become.
They start watching the clock, monitoring every sensation in their body, and evaluating whether they're falling asleep fast enough.
The mind becomes so focused on sleep that it accidentally keeps itself awake.
When Sleep Problems Come From the Body
This is the category I thought about most during my conversation with that young woman.
Sometimes the body is sending signals that interfere with sleep, regardless of how calm a person's mind may be.
Digestive issues can play a role. Hormonal changes can play a role. Blood sugar imbalances, nutrient deficiencies, inflammation, melatonin production, and cortisol patterns can all affect sleep.
For women, sleep can change throughout different phases of the menstrual cycle. Pregnancy, postpartum recovery, perimenopause, and menopause can all create significant changes in sleep quality.
The body has its own language, and sleep is often one of the first places where that language shows up.
When Sleep Problems Come From Breathing
This is the category that surprises people the most.
Many people spend eight hours in bed and still wake up exhausted. They assume they're sleeping because they were in bed all night.
But sleep quality matters.
Snoring, mouth breathing, sleep apnea, and other breathing disruptions can prevent the body from getting the deep, restorative sleep it needs.
A person may have no memory of waking up during the night, yet their body is working overtime.
You wake up tired, foggy, irritable, and wonder why.
The answer isn't always stress. Sometimes it's breathing.
What stayed with me after that call wasn't whether she had MCAS or SIBO.
It was how quickly one answer became two, and how two could easily become four.
Information is powerful. I use AI. I read. I research. But every piece of information has to pass one simple test:
Is this getting me closer to my goal, or further away from it?
Because when it comes to sleep issues, too much information can sometimes become the very thing that keeps people stuck.
