Summary
Dr. Stephen Cabral covers several health topics in this Friday review episode, including a discussion of inspiratory muscle strength training (IMST) research from the University of Colorado. The study showed that just 30 inhalations per day using a resistance breathing device reduced systolic blood pressure by 12% after six weeks, potentially taking someone from hypertensive to normal range. Cabral highlights additional benefits for sleep apnea and cognitive function. The episode also features a product review of the TruMedic InstaShiatsu foot massager, which Cabral recommends for parasympathetic nervous system activation through foot reflexology. He discusses IgG food sensitivity testing and how elevated or absent immune responses can indicate gut permeability issues, and wraps up with updates on his seasonal detox protocol and bioregulatory medicine work.
Key Points
- Inspiratory muscle strength training (IMST) involves 30 inhalations per day through a resistance device, taking about 5 minutes
- University of Colorado research showed IMST reduced systolic blood pressure by 12% after six weeks
- IMST has also shown benefits for sleep apnea and cognitive function including memory and reduced brain fog
- Foot reflexology activates the parasympathetic nervous system through proprioceptors in the feet
- IgG food sensitivity testing can reveal gut permeability issues when many foods are elevated or when no immune response is detected at all
- Nine out of ten people are functionally deficient in magnesium based on hair tissue mineral analysis
Key Moments
5-minute breathing workout lowers blood pressure by 12%
Dr. Cabral introduces inspiratory muscle strength training research from the University of Colorado showing that just 30 inhalations per day for five minutes can lower systolic blood pressure by 12% and improve brain function after six weeks.
"inspiratory or inspiratory muscle strength training. And so you're actually not training the muscles as you would think, like your chest and your bi's and your tri's and your glutes. So what you're doing though is strengthening the muscles of respiration or breathing. So what this device does, and it's very unique, it's very interesting, and they've spent a lot of money on this research."
IMST reduces blood pressure enough to eliminate need for medication
Cabral explains that 30 inhalations per day after six weeks reduced systolic blood pressure by 12%, potentially moving someone from 140/90 to 128/78, eliminating the need for blood pressure medication.
"Just 30 inhalations per day. We've seen it help people with sleep apnea, seen it help with also blood pressure. So 30 inhalations about five minutes after six weeks, systolic blood pressure, okay? So basically the top number when you're getting your blood pressure reading dropped by 12%."
IMST device works like breathing through a resistance thermometer
Cabral describes how the IMST device works mechanically, noting it trains inhalation against resistance. He expresses hope for future nasal versions since nose breathing brings in more oxygen than mouth breathing.
"Think about putting that in your mouth and what it does is it's sucking through that, sucking basically in the mouth, the air, and you are sucking back. So you're having to actually work on your breathing, right?"
