Improve Your Lymphatic System for Overall Health & Appearance

Episode 252 Oct 27, 2025 1h 40m 10 insights
Here I explain the lymphatic system, a crucial bodily network for overall health and appearance. I explain how the lymphatic system works to remove cellular waste and fluid from your organs and combat infections. I provide science-based tools that support your lymphatic system for the sake of health and appearance, including: how to reduce fluid retention in your limbs, trunk or face, how to eliminate 'bags' under your eyes and brain fog, and how to improve cardiac health and longevity. Because your lymphatic system lacks a central pump, it needs the mechanical forces generated by specific types of bodily movement, breathing and pressure to circulate your lymph properly, and I explain how you can activate these. I also explain how to support optimal functioning of your glymphatic system, a brain- and spinal cord waste-clearing system active during sleep that is crucial for brain functioning and longevity, including to prevent dementia.

Actionable Insights

1. Daily Movement for Lymphatic Health

Ensure you move enough each day, aiming for at least 7,000 steps, as low-level muscular contractions from walking and other daily activities are essential to passively move lymphatic fluid through the one-way vessels and prevent sluggishness.

2. Consistent Hydration for Lymph Flow

Hydrate well throughout the day to support lymphatic flow and drainage, drinking 16-32 ounces of water upon waking and 8-16 ounces every one to two hours thereafter to maintain proper blood volume and lymphatic function.

3. Diaphragmatic Breathing for Lymph Drainage

Practice diaphragmatic breathing (inhaling deeply with belly moving out) a few times a day to create a pressure differential that encourages the movement of lymph fluid from the cisterna kylia back into the blood supply, especially when sedentary.

4. Side Sleeping for Brain Lymphatics

Sleep on your side to encourage optimal glymphatic drainage from the brain, which clears waste products and reduces brain fog and facial puffiness. Consider elevating your feet 5-10 degrees and ensuring your head is slightly tilted up with a pillow.

5. Regular Cardiovascular Exercise

Engage in regular cardiovascular exercise (e.g., 150-200 minutes of Zone 2 cardio per week) to promote the growth and remodeling of lymphatic vessels in the heart and brain, which helps clear waste products and mitigate inflammation.

6. Gentle Lymphatic Massage Technique

When performing lymphatic massage, use light touch and gentle rubbing or shearing of the skin, potentially followed by light tapping or padding, especially around the clavicles and cisterna kylia, and moving from limbs inward, avoiding firm pressure on vessels or lymph nodes.

7. Bouncing/Shaking for Lymphatic Flow

Engage in activities like rebounding (bouncing on a small trampoline) or shaking your body to encourage lymphatic fluid movement, as these movements leverage the one-way nature of lymphatic vessels to push fluid towards the heart.

8. Treading Water or Swimming

Tread water or swim in a pool to create lymphatic drainage, as the physics of water interacting with superficial skin vessels and the shearing of skin during movement helps squeeze lymphatic capillaries.

9. Post-Exercise Lymphatic Clearance

After intense lower body exercise, engage in light swimming or treading water, or use compression boots, to help clear lymphatic fluid buildup and reduce soreness and heaviness in the limbs.

10. Long Wavelength Light Exposure

Expose your skin to long wavelength light (red, near infrared, infrared) from devices or low solar angle sunlight (e.g., 10-30 minutes in late afternoon/evening) to reduce inflammation, improve skin appearance, and enhance lymphatic function.
