If you breathe through your mouth, read this: Image
Mouth breathing has been shown to cause:

· ADHD
· Asthma
· Sleep disorders
· Chronic fatigue
· Allergic reactions
· Facial disfiguration
· Decreased brain activity

What most people don't know is how breathing through the mouth affects the brain. Image
Researchers at the University of Korea found did a study on mouth breathing.

They found that people who breathed through their mouths had decreased function in their brains.

It's been shown that around 50-60% of people are mouth breathers. Image
Why is mouth breathing bad?

Breathing through your mouth you put us in a sympathetic state of "fight or flight".

It can also lead to bacteria in the mouth, shallow chest breathing & disrupted sleep.

For most people, mouth breathing is a hidden handicap. Let's fix that. Image
The mouth was meant for eating & talking. The nose was meant for breathing.

Breathing through your nose is optimal for your health, decreases stress & improves your physical performance.

It was built for one purpose: To support your respiratory system. Image
Benefits of Nasal breathing

· Filters allergens
· Improves your sleep
· Slows down breathing
· Improves lung capacity
· Aids your immune system
· Increases oxygen uptake
· Lowers your risk of snoring & sleep apnea
· Increased moisture & warmer air for lungs Image
Nasal breathing also stimulates the production of nitric oxide.

Nitric oxide (NO) is a molecule that plays role in delivering oxygen into cells.

NO can influence mood, weight, the immune system & sexual function.

Nasal breathing alone can boost nitric oxide by up to 6x. Image
A study tested 10 runners using nasal breathing.

They found that their respiratory rate, breaths per minute & ratio of oxygen intake to carbon dioxide output lowered during nasal breathing.

It allowed for more oxygen to get in the bloodstream.

2 ways to start breathing through the nose

Method #1 - Start with awareness.

Anytime you find yourself breathing through your mouth bring yourself back to nose breathing.

Set alarms for as a reminder to nasal breathe throughout the day.
Method #2 - Tape the mouth

Taping your mouth during the day when you're at your desk doing work or exercise.

Mouth tape forces us to start breathing through the nose & the safest time to do this is to do it when you're awake.

I recommend hostage tape or 3M micropore tape. Image
If you have small obstructions that prevent you from breathing through your nose I would also recommend using Breatheright nasal strips.

Lack of nose breathing can reduce the size of your nostrils making it harder to breathe.

This helps open them up to allow for more air. Image
If you have larger disruptions like a deviated septum then you'll need to see a qualified professional to get that fixed.

If you're not sure if you have one or not then go see a nose specialist to find out.
One thing I'll add is that I'm not perfect at this at all.

I was a mouth breather from the age of 5 until I learned about this at 41.

At times, I find myself breathing from my mouth & that's okay.

I'm willing to work on this for as long as it takes.

Changes take time.
The simplest way to improve the quality of your health is to start breathing through your nose. It costs nothing and the reward is high.

8 health trends that need to die in 2026:

1) Cold plunging.

Good for dopamine but studies show it blunts muscle growth and it doesn't improve recovery in a meaningful way.

For most people it's become a virtue signaling marathon on Instagram rather than an actual health tool.
2) Extreme "clean eating."

The moment you label food "clean" or "dirty" you've started a war with your plate.

I've watched this push people into disordered eating and social isolation.

You can be lean and healthy eating whole foods diet with room for your favorite foods.
3) Obsessive biohacking gadgets.

CGMs when you're not diabetic. 4 wearables on your wrist. Biofeedback devices on your nightstand.

You're turning normal body variation into anxiety.

Steps. Sleep. Weights. Nature. That covers 90% of the game. Stop overcomplicating it.

1 in 3 Americans are insulin resistant and it's silently killing them from the inside.

What most don't realize is you can reverse it in 3 to 6 months without a single medication.

Here's the exact protocol on how to do it (bookmark this): Image
8 Warning Signs of Insulin Resistance

1. Excess belly fat
2. Brain fog
3. Constant hunger
4. Low energy
5. High inflammation
6. High blood pressure
7. High blood sugar
8. High Triglycerides
It's a sign of high glucose and high insulin.

Your cells ignore insulin's signal to absorb glucose thus your body pumps out more insulin to compensate.

The result is fat storage, chronic fatigue, brain fog, and type 2 diabetes.

The good news is this is fixable with the right systems.

If you want to live to 100 or longer track these 6 key metrics:

1. Cardiorespiratory fitness

What to track: VO₂max, one mile run times or 3 mile cycle times.

Your cardio system is one of the best predictors all-cause mortality.
2. Muscle strength and lean mass

What to track: grip strength, FFMI, basic strength standards.

Low strength and muscle mass are hallmarks of frailty and higher death risk as we age.

High strength and muscle mass equal a better quality of life.
3. Autonomic nervous system health

What to track: heart rate variability (HRV) and resting heart rate trends.

These reflect stress resilience and recovery capacity, not just “fitness.”

If you need to get your shit together in 2026, read this:
1. Stop being easily offended. If you’re easily offended you’re easily manipulated.

2. Get your body lean and healthy. Getting in shape is the lead domino that makes your entire life better.
3. Treat food as fuel for the brain and body. Put garbage in and you get garbage back. Put high quality foods in and you’ll improve your energy and mental health.

4. Sleep is your waste removal system. Prioritize it like your life depended on it.

Surprising numbers to track to see how long you'll live:

1. Body fat %
2. Bone density
3. Grip strength
4. 1 mile run time
5. Daily fiber intake
6. Resting heart rate

Here’s why 👇
1. Body Fat

Excess body fat, especially visceral fat, drives insulin resistance, inflammation, and chronic diseases.

Lower, healthy body fat means better hormones, better energy, and a longer healthspan.

Use the chart below to determine a healthy percentage % Image
2. Bone density

Low bone density increases fracture risk, loss of independence, and mortality.

You don’t “feel” bone loss until it’s too late. Strength training protects it early.

Strong bones are your insurance against aging.

After 20+ years of health coaching, here is every fat loss tip I could come up with:

1. Take 5 grams of creatine for the muscles. Take 10-15 grams of creatine for the brain.
2. To build muscle lift weights 3x a week, hitting each muscle at least 2x. Every session, add more reps or weight. Aim for an FFMI of 18.5-22 (men) or 15.5-18.5 (women)

3. To lose weight, eat at a calorie deficit of 500 or slightly higher depending on how much you have to lose.
4. Focus on 2 numbers: Calories and protein. For protein aim 30-60 grams a meal and a total of .7 to 1 gram per lbs of bodyweight.

5. Eat 3 nutrient-dense meals according to your circadian rhythms. No snacking. This improves energy and automates hunger.
