What does the color of your mucus really mean? 👃🧬

Your mucus isn’t random — it’s your body’s real-time health report.

White = normal protection
Yellow = immune system activating
Green = strong immune response (that green color comes from myeloperoxidase inside white blood cells)
Red = blood / irritation
Brown = old blood, dust, smoke, debris
Black = heavy pollution or environmental exposure

Your nose is your first line of immune defense.
If it can’t filter what you’re breathing, that “crud” goes straight into your lungs.

That’s why nasal hygiene matters:
✔️ Saline spray
✔️ Xylitol spray
✔️ Saline rinses
✔️ Sometimes saline + a drop of baby shampoo

Protect your nose.
Protect your lungs.
Protect your health.

👅 How to Check Tonsils When the View Is Tricky

Sometimes it’s easy to see the back of the throat.
But in kids—or adults—with large tonsils, mouth breathing, tongue-tie, or a narrow palate, the view can be much harder.

Instead of tonsils, all you see is hard palate.
That’s often a Mallampati class 4 view—and it’s an important clue.

A few key tips that can make a big difference:
✔️ Sit upright
✔️ Use the sniffing position (chin neutral, gentle neck extension)
✔️ Avoid chin-tuck or over-extension
✔️ Ask for a gentle tongue extension and “ahhh”
✔️ Try slow mouth breathing to relax the throat

If the tonsils still aren’t visible, that’s not a failure—it’s information.
A crowded throat and limited view often go hand-in-hand with airway restriction.

In those cases, further evaluation—like a CBCT or flexible scope exam—may be helpful to understand what’s happening beyond what you can see.

💬 Parents and providers:
Have you ever struggled to get a clear view of the tonsils?
What techniques have helped—or what questions do you still have?

Mold in the home is a potentially serious health hazard — not just something to wipe away or ignore.

For some individuals, especially those with genetic susceptibility, ongoing mold exposure can contribute to sinus symptoms, airway irritation, fatigue, brain fog, sleep disruption, and chronic inflammation.

So instead of asking “How do I clean it?”
Ask:

➡️ “Where is the moisture coming from?”

Because the rule is simple:

No water → no moisture → no mold.

Certain building features can make mold more likely: flat roofing, inadequate drainage, enclosed bathrooms without ventilation, and slab foundations without v***r barriers. These can all increase moisture retention inside the home.

And beyond design, everyday moisture sources — humidifiers, recurring bathroom steam, under-sink leaks, window condensation, and rain sneaking in under balcony sliders — can also contribute.

A simple place to start is adding a dehumidifier — especially if you live in a coastal or humid region.
Keeping indoor humidity around 40–50% — and below 55% — can make a meaningful difference in preventing mold growth while still protecting airway comfort and sleep.

⸻

🟢 Share this with someone who keeps cleaning mold instead of investigating it.
🟢 And tell me — what have you learned about dealing with mold?

Whether it’s testing, remediation experience, inspector recommendations, or home strategies — your insight could help someone who doesn’t yet know where to begin.
If you have credible resources, professional contacts, or testing tools, drop them below — community knowledge truly matters here.

⚡Could restricted tongue mobility really affect posture, breathing, and even cause numbness in the arms? 🤔👉 Let’s learn from this case study.

Thoracic Outlet Syndrome (TOS) occurs when nerves or blood vessels that pass from the neck into the arms become compressed — often between the collarbone and the first rib. This can lead to tingling, numbness, weakness, or even pain in the arms and shoulders.

Now here’s where it gets interesting. 👇
In patients with hypermobility, the connective tissue is looser and less supportive, which can lead to forward head posture and increased tension through the neck and shoulders.

A tongue-tie adds another layer to that tension. It’s a condition where a band of connective tissue under the tongue restricts its mobility and connects tightly to the floor of the mouth. That restriction can extend through the fascia of the neck and even the diaphragm, influencing posture, breathing, and overall body alignment.

When that restriction is released, the fascia can relax, the head and neck can come back, and compression patterns in the thoracic outlet often improve.
That’s why some patients notice immediate changes in posture, breathing, and arm symptoms after a tongue-tie release.

Many people ask me about the relationship between tongue-tie and hypermobility. The truth is, patients with hypermobility are more sensitive to restrictions. Their connective tissue is already loose, so a tongue-tie stands out more — and releasing it can make a profound difference.

✨ A small change in one area can have a big impact throughout the body.

Have you ever seen something like this in yourself or your patients?

Lingual Frenuloplasty for Posterior Tongue-Tie

This video highlights advances in the surgical technique with a precision-based approach to releasing the restrictive lingual frenulum as well as the repair with sutures and periacryl glue. Key anatomical landmarks and the necessary depth of release are reviewed, along with specific endpoints that ensure the effectiveness of the procedure.

The Breathe Course is coming up next week! We go into all the details of the procedure and much more! It’s available in person, live stream, and on-demand. https://www.breathecourses.com/

Sleep is essential for every age! Here’s a quick guide on how much healthy sleep you should aim for:

- Preschoolers (3-5 years): 10-13 hours per day
- School-Age Children (6-13 years): 9-11 hours per night
- Teenagers (14-17 years): 8-10 hours per night
- Adults (18-64 years): 7-9 hours per night

Adequate sleep plays a crucial role in emotional, cognitive, and physical functioning. For children and teens, sleep supports growth and development, helping them thrive in their daily activities. For adults, quality sleep enhances mental clarity, mood regulation, and overall well-being.

Getting the right amount of rest is key to feeling your best and staying healthy. Too much or too little sleep can be the sign of a problem!

PALATAL FLUTTER SIGN: EXPLAINED CLEARLY!

Palatal flutter is a test to predict the likely results of treatment in patients who snore.

Have the patient attempt to make a snoring sound with their mouth open, then have them perform lingual palatal suction (LPS) and attempt to make the snoring sound again with their tongue held against the palate.

Sign (+) Positive / Quiet: Patient is able to create palatal flutter noise with the mouth slightly open (mouth breathing) but is unable to create the same noise with the mouth closed, tongue up, nasal breathing*. (*=gentle nasal breathing, not strong nasal snorting).

Sign (-) Negative/ Loud: Patient can create the palatal flutter noise with the mouth slightly open (mouth breathing) and is able to create the same noise with the mouth closed, tongue up, nasal breathing*.

If they are QUIET with the tongue-up (POSITIVE SIGN),  they will probably snore much less when they keep their tongue-up!! —Consider mouth taping, myofunctional therapy, nasal hygiene AND/OR nasal, tonsil, soft-palate, tongue-tie (soft tissue) procedures.

If they are still LOUD with the tongue-up (NEGATIVE SIGN), then they will probably need a more thorough evaluation to fully resolve the snoring. ——Consider mouth taping, myofunctional therapy, nasal hygiene AND/OR nasal, tonsil, soft-palate, tongue-tie (soft tissue) procedures.…. as well as possible palate expansion, weight loss, oral appliance therapy, CPAP, jaw surgery.

What if you cannot flutter your palate? —Test does not apply to your case. —Probably do not have excessive soft palate redundancy. —And, if snoring or obstruction is present, may be related to other sites of obstruction: nasal passage, lateral pharyngeal wall, tongue-base, epiglottis.
