Theta Chamber Side Effects: What to Expect Before Your First Session

Greg Muchnij • September 30, 2025

Most people ask me this question before their first Theta Chamber session: “What are the side effects?”


The answer may surprise you.


When you hear the phrase side effects, you probably think of the long warning labels on prescription bottles or the TV commercials listing dozens of things that can go wrong. It’s natural to wonder if stepping into something as advanced-sounding as a Theta Chamber will have risks attached.


Here’s the good news: Theta Chamber therapy is designed to be safe, non-invasive, and deeply restorative. The “side effects” most people report aren’t dangerous—they’re usually short-lived and part of the healing process. Think of them as signs your body and mind are adjusting to a new level of balance.


At MyChiropractor Health & Wellness in Phoenix, AZ, I’ve guided countless patients through their first session. Many come in with questions, concerns, and even a little hesitation. They leave feeling lighter, calmer, and hopeful.


So let’s break down what you can expect, what the science says, and why my team and I are here to make sure you’re supported every step of the way.

What Is the Theta Chamber?

The Theta Chamber is an advanced neurotechnology tool that helps guide your brain into a state called the theta brainwave state. This is the same restorative state you enter during deep meditation or the early stages of sleep.


In this state, your brain is more open to healing, balance, and resetting old patterns—whether they’re linked to stress, chronic pain, or fatigue.


At our Phoenix clinic, we use the Theta Chamber as part of a comprehensive approach to help with:


  • Anxiety, depression, and mood balance
  • Sleep issues and insomnia
  • Chronic fatigue
  • Pain management
  • Recovery from stress or trauma


It’s not just a “relaxation pod”—it’s a powerful therapy designed to support your nervous system at its core.

The Most Common Theta Chamber Side Effects

While the Theta Chamber is safe and non-invasive, it’s important to know what you might experience, especially during your first few sessions.


Here are the most common side effects patients report:


1. Mild Drowsiness or Grogginess


Similar to waking up from a nap, you may feel a little foggy right after your session. This usually fades within minutes as your brain “reorients.”


2. Temporary Lightheadedness


Because the chamber engages your vestibular system, a small percentage of patients feel slightly lightheaded. This is brief and typically resolves by the time you leave the clinic.


3. Emotional Release


Some people experience unexpected feelings—calmness, joy, or even a gentle release of stored stress. This is a positive sign that your body is letting go.


4. Increased Sleepiness Later That Day


Many patients report the best sleep they’ve had in months after their session. Others may just feel more ready to rest earlier than usual.


5. Heightened Awareness or Clarity


Not exactly a “side effect,” but some describe a new sense of clarity or focus that lasts days after their session.


The key thing to remember is that none of these side effects are harmful. They are part of your body’s natural way of recalibrating and adjusting to the therapy.

How Theta Chamber Side Effects Compare to Traditional Treatments

Here’s where perspective matters.


Medications often come with a long list of risks: nausea, headaches, dependency, organ strain, and more.

Surgery carries the possibility of complications, downtime, and invasive procedures.


Standard pain management may only mask symptoms rather than address the root imbalance in your nervous system.


By contrast, the Theta Chamber is:


  • Drug-free
  • Non-invasive
  • Guided and monitored by trained professionals


At our Phoenix clinic, patients love knowing they’re stepping into something that helps restore balance naturally—without trading one health problem for another.

A Real-Life Example: Elisha Mae’s Story

Sometimes, the best way to understand the safety and benefits of the Theta Chamber is through real people who’ve experienced it.

One of our patients, Elisha Mae, shared this Google review after completing 8 sessions for rheumatoid arthritis, chronic pain, and fatigue:


“I just finished at my quarterly Rheumatoid arthritis appointment and they couldn't figure out why all my bloodwork looked so much better without changing my medication and I had been taking less than they recommended. I am pretty sure it had to do with doing the work with Dr. Greg and listening to my body and what it was telling me to do, to heal at deeper levels and bring my nervous system back into balance... Thank you Dr. Greg, and staff for your amazing support and guidance on this journey.”


Her experience speaks volumes: not only did she experience relief, but even her doctors noticed measurable improvements in her health.
