The Lymphatic System may seem like it functions like the circulatory system by moving fluid through a series of ducts to circulate around the body. However, unlike the circulatory system there is now way for the lymph, whish is the fluid of the system, to pump on its own. The body figured out an ingenious way to circulate the lymph by way of contracting your muscles. By contracting muscles the lymph is able to fight gravity and travel up the ducts to be able to circulate. <\/p>\n\n\n\n
Inactivity, therefore, will slow the rate of drainage allowing metabolic waste and inflammatory molecules to build up. This stagnant state will help contribute to swelling, slower recovery, fatigue, and even cognitive dullness. <\/p>\n\n\n\n
Exercise, especially rhythmic movement like walking, resistance training, and deep diaphragmatic breathing, acts as a mechanical pump that propels lymph fluid through the body\u2019s vessels (Hsu et al., 2021).<\/p>\n\n\n\n

The Glymphatic System: The Brain\u2019s Cleaning Mechanism<\/h2>\n\n\n\n
Until relatively recently, about a decade ago, scientists believed the brain lacked a lymphatic network. A breakthrough occurred at the University of Rochester discovering the Glymphatic System – a glia-dependent clearance pathway that mirrors the lymphatic system within the brain using cerebrospinal fluid (CSF) (Iliff et al., 2012).<\/p>\n\n\n\n
Most of the benefit is derived during deep, slow-wave sleep, because interestingly the neuronal cells constrict slightly allowing for the CSF and interstitial fluid, fluid around the cells, to wash around removing built up waste. This waste can be a variety of molecules, some of which are now widely accepted as toxins like amyloid-\u03b2 and tau (Xie et al., 2013) which are proteins linked to Alzheimer’s and generalized brain fog.<\/p>\n\n\n\n Sleep does not have to be the only time for your brain to clear out this metabolic waste build-up. Emerging research is coming to light on the effect of exercise and its ability to cleanse the CSF. Cardiorespiratory exercise as well as more subtle changes like postural corrections and daytime movement aids the glymphatic system to influence CSF dynamics helping maintain a baseline clearance throughout the day. <\/p>\n\n\n\n (I’ll dive more into why exercise is even more beneficial in a later section)<\/p>\n\n\n\n In Alzheimer\u2019s disease (AD), two key proteins – amyloid-\u03b2 (A\u03b2) and tau – accumulate abnormally and disrupt synaptic communication. Traditional views, known as the Amyloid Cascade Hypothesis<\/em>, propose that A\u03b2 buildup triggers tau pathology, but new research has challenged this one-way model.<\/p>\n\n\n\n A comprehensive 2023 review highlights that soluble oligomeric forms of both A\u03b2 and tau\u2014not their insoluble plaques or tangles\u2014are the most toxic to neurons. These oligomers impair long-term potentiation (LTP), which is the neural process underlying memory formation. Remarkably, both proteins appear to require the amyloid precursor protein (A\u03b2PP) to enter neurons and glia, essentially as a trojan horse, acting through shared pathways that damage synaptic function and memory.<\/p>\n\n\n\n This suggests that A\u03b2 and tau operate in parallel through A\u03b2PP, not in series\u2014creating a feedback loop that amplifies cognitive decline (Frontiers in Molecular Neuroscience, 2023).<\/p>\n\n\n\n Here\u2019s where the glymphatic system becomes essential, inefficient clearance of these soluble proteins increases their interstitial fluid concentration, which accelerates uptake into neurons and worsens toxicity. Thus, a sluggish glymphatic system may indirectly intensify the molecular cascades of AD.<\/p>\n\n\n\n Physical activity is one of the most powerful ways to stimulate both lymphatic and glymphatic flow. Aerobic and resistance training improve vascular pulsatility and arterial compliance, which in turn enhance perivascular pumping of CSF through the brain. Animal and human studies show that regular exercise:<\/p>\n\n\n\n Another fascinating aspect occurs after consistently performing aerobic exercise called lymphangiogenesis. This refers to the formation of lymphatic and glymphatic vessels from pre-existing ones driven by the stimulation of growth factors (as a side note its not fully understood at this time if glymphatic vessels “grow” or simply become enhanced\/remodel). This means as people routinely exercise their baseline levels of this “waste management” system is increased helping to have a higher rate of cleansing throughout the day. <\/p>\n\n\n\n In short, when you move your body, you help your brain “breathe”.<\/p>\n\n\n\n Converging evidence from both human and animal models fully support the proposition that regular physical exercises aids the bodies endogenous system (Lymphatic System) to clear cellular waste and support your immune response. These finding have also recently been found to occur in the brain, termed the glymphatic system, to help your brains ability to function.
