Lymphatic inefficiency, maybe.

Impairment sounds too permanent, when this is often an intermittent, “on average” sort of issue - not a complete freeze.

Yes,

it turns out toxins (environmental, die-off and waste of cells from infection, dietary, lifestyle) are important to everyone,

not just vegans in Sandler movies.

It seems pretty common for people to read "linked to" and interpret that as "caused by". It feels like media had kind of pushed that for a long time.

Stopping back in, because I unironically came across someone's almost-surely AI assisted summary that does a better job than I have summarizing the processes being discussed:

== === Why the Sick Get Sicker Most people think illness progresses because of pathogens, toxins, or genetics — but the deeper truth is that tension, stress, and breathing patterns control the trajectory of health more than anything else.

When the body is stressed, the breath changes.

When the breath changes, the lymph stagnates.

When the lymph stagnates, toxins accumulate.

When toxins accumulate, inflammation accelerates.

And that is how sick becomes sicker.

Here’s the breakdown:

1. Stress Immediately Changes Your Breathing Pattern

When the nervous system senses stress — emotional, physical, mental, or energetic — breathing becomes:

• shallow

• rapid

• high in the chest

• tight in the ribs

• limited in diaphragm expansion

This cuts oxygen supply, raises cortisol, and signals the body to brace.

Bracing = stagnation.

2. Your Breath Controls Your Lymphatic System

The lymphatic system is the body’s drainage system, and it has no pump of its own.

It relies entirely on: • diaphragmatic breathing

• muscle movement

• fascia softness

• a calm nervous system

Shallow breathing = no diaphragm movement.

No diaphragm movement = lymph stagnation.

When lymph stagnates:

• waste can’t drain

• toxins recirculate

• inflammation builds

• swelling increases

• the immune system gets overwhelmed

This is why people in long-term stress decline rapidly.

3. Chronic Tension Physically Constricts Detox Pathways

Tension in the shoulders, neck, jaw, abdomen, and ribs acts like a clamp on the lymphatic system.

Chronic tightness:

• blocks lymph nodes

• stiffens fascia

• shuts down circulation

• compresses nerves

• restricts oxygen

• slows detox

The body becomes a closed loop where waste can’t leave — so it begins leaking into tissues, joints, and organs.

This accelerates aging, pain, brain fog, and inflammation.

4. This Is the Progression From Sick → Sicker

When breath + lymph + fascia are blocked:

Phase 1 — Shallow breathing

Fatigue, anxiety, tight chest, poor digestion.

Phase 2 — Lymph stagnation

Swelling, puffiness, inflammatory symptoms, chronic infections.

Phase 3 — Detox recirculation

Migrating symptoms, rashes, headaches, histamine issues, chemical sensitivity.

Phase 4 — Systemic overload

Autoimmune symptoms, mold sensitivity, debilitating fatigue, hormone disruption.

It appears “mysterious,” but physiologically it is predictable.
