The prevalence of PMS

The myth of quitting

Vaping is often promoted as a tool to help people stop smoking, yet the data tells a different story. Although 85% of e-cigarette users report starting vaping to quit cigarettes, a 2013 study across four countries published in the American Journal of Preventive Medicine found they were no more likely to quit than those who never vaped. In fact, reports show that vaping often reduces the likelihood of quitting altogether, with around 70% of users becoming dual users—continuing to smoke while vaping.

What’s actually in the vapour

A 2017 Harvard study analysing 24 flavoured e-cigarette brands found that every single one contained at least one aldehyde or flavouring chemical listed as “High Priority” by FEMA or classified by the FDA as Harmful or Potentially Harmful. Despite this, these products are inhaled repeatedly every day.

We also don’t fully understand how common ingredients—propylene glycol, vegetable glycerin, flavourings, and other additives—behave when heated and aerosolised, especially when used 20 to 30 times a day beyond their original FDA approval context.

Lung injury and toxic exposure

The risks became highly visible during the 2019 outbreak of vaping-associated lung injuries, which resulted in 2,807 hospitalisations and 68 deaths in under a year. One major contributing factor was vitamin E acetate—an additive whose harmless-sounding name masked its severe effects when inhaled.

Research from Johns Hopkins examining 56 e-cigarette devices found that many produced aerosols containing potentially unsafe levels of lead, chromium, manganese, and nickel. These metals originate from heated metal coils and are linked to lung, liver, immune, cardiovascular, and neurological damage, as well as certain cancers. The danger is amplified by ethyl maltol, a common artificial sweetener shown to facilitate the transport of heavy metals into cells.

‍

Cardiovascular and clotting risks

Vaping also exposes users to high concentrations of ultra-fine particles and toxins at levels comparable to conventional cigarettes. These particles activate platelets, increasing their tendency to clump together—an important contributor to clot formation and cardiovascular disease.

Research from Poland suggests that chemicals such as acrolein and formaldehyde, created during e-liquid heating, accelerate arterial hardening and narrowing by more than 1.6 times. Studies from the University of California, San Francisco found that daily e-cigarette use doubles the risk of heart attack, while dual users face a fivefold increase compared to non-smokers.

‍

Hormones, fertility, and pregnancy

The effects extend beyond the lungs and heart. A 2022 study found that vaping doubles the risk of erectile dysfunction in men aged 20 and over. A separate 2020 study of 1,221 men showed a 34% reduction in total sperm count among e-cigarette users compared to non-users.

E-cigarettes contain endocrine-disrupting compounds capable of interfering with hormonal balance and reproductive function. In women, a large study involving 71,940 participants found that unfavourable birth outcomes increased by 62% among those who used e-cigarettes during pregnancy.

‍

Immune suppression and hidden contaminants

Vaping weakens the body’s ability to fight infections. A 2018 study published in BMJ Thorax showed that e-cigarette vapour damages alveolar macrophages—key immune cells responsible for clearing pathogens, toxins, and allergens from the lungs.

Additional concerns come from contamination: an analysis of the ten top-selling U.S. brands detected endotoxins above the limit of detection in 23% of samples tested, adding another layer of inflammatory risk.

‍

Beyond health: society and the environment

Beyond physiology, there is a broader cost. The argument that vaping benefits society is weak when considering its environmental impact. Each disposable vape contains a lithium-ion battery; in the UK alone, the lithium discarded annually in vapes could produce around 1,200 electric vehicle batteries.

On a social level, vaping increasingly functions as an emotional crutch—an “adult pacifier” that outsources stress regulation and potentially disrupts brain chemistry and hormonal balance rather than addressing underlying causes.

‍

The real experiment

E-cigarette use continues to grow rapidly, while robust long-term research on its health effects remains limited. What we do know already points to serious risks—many of which mirror or compound those of smoking itself.

Don’t be society’s guinea pig. It’s time to confront the dark side of vaping.

Are you currently exposed to phthalates on a regular basis? Were you exposed during early developmental stages—for example, through maternal exposure such as a mother working in a hair salon while pregnant? Have you noticed symptom improvement after reducing phthalate exposure?

Higher phthalate levels have been associated with a two-fold increase in the rate of endometriosis. Phthalates are present in almost anything fragranced and are widely used in soft plastics, vinyl, cleaning products, nail polish, and perfumes. As early as 2002, environmental groups reported that over 70% of personal care products contained phthalates. Today, according to the Environmental Protection Agency, more than 470 million pounds of phthalates are produced each year.

Phthalates are now officially recognised as reproductive toxins throughout both the European Union and the United States. Animal studies show that rats given high doses of certain phthalates stopped ovulating altogether. Phthalates reduce oestrogen production by ovarian follicles—oestrogen being one of the primary drivers of follicle growth and egg development in both animals and humans. Suppression of oestrogen by follicle cells would be expected to impair follicle growth, helping explain why women with endometriosis often exhibit significantly higher phthalate levels than those without the condition.

Potential sources of exposure are extensive. Plastics can leach into food, particularly when food is packaged while hot or stored in plastic for long periods. Personal care products are a major contributor, including cosmetics, hair products, lotions, infant care products, medications, medical devices, nail polish, and perfumes.

Vinyl products are another source, such as shower curtains, flooring, wallpapers, blinds, diaper mats, rain gear, inflatable mattresses, school supplies, car interiors, and yoga mats. Additional exposures may come from air fresheners, electronics, plastic jewellery, sex toys, and children’s toys.

Given their prevalence and biological impact, understanding and minimising phthalate exposure is an important consideration in hormone and reproductive health.

What is the Lymphatic System?

The lymphatic system is becoming increasingly more talked about but is still, in my opinion, one of the least appreciated and under-utilised systems in the restoration of movement dysfunctions and chronic health complaints.

Everybody, including health practitioners and those in the fitness industry, could benefit from understanding and implementing lymphatic techniques. You can consider that a homeostatic balance of the internal environment can be a true measure of health.

Lymphatic techniques can, therefore, aid the body in moving towards more of an internal state of homeostasis.

How does the lymphatic system function?

The lymphatic system is, in essence, the sewage system of the body.

It has the incredible ability to trap nearly all soluble antigens, roughly 99%, with its role in waste removal. This is significantly important for the other body systems to not become overwhelmed and develop issues as well.

The lymphatic system contains the thymus, an endocrine organ which is responsible for the development of T-lymphocytes, immune cells that are involved in fighting infection through the process of cell-mediated immunity.

The spleen plays a key role in the lymphatic system as the largest lymphatic organ, having a vital role in a host of detox processes, such as:

• Filtering blood
• Removing old dead red blood cells
• The maturation of lymphocytes and macrophages to aid in fighting infection

The splenic communication of the tenth cranial nerve, the Vagus nerve, is crucial in reducing inflammatory cytokine production.

The tonsils also form part of the structure of the lymphatic system. With the tonsils formed of lymphatic tissue, housing lymphocytes and macrophages, they protect the digestive system and lungs from pathogens entering through the nose or mouth.

There is also a deep association with the gastrointestinal system through gut associated lymphoid tissues (GALT) known as Peyers Patches, with the role of the gastrointestinal system intrinsically linked to the immune system. Estimates suggest that roughly 70-80% of immune function is beholden to gastrointestinal health.

This amazing system also comprises millions of lymphatic vessels which, if placed end to end in a continuous line, would circle the earth four times! Alongside these vessels there are over seven hundred lymph nodes within the body, with the most populated areas being the neck, skin and the intestines.

This mass of lymphatic vessels works in uniform direction towards the heart, with valves interspersed to prevent any backflow from occurring. This one-way system is aided by the structure of the vessels which allow fluids to flow in the direction of clearance, but with numerous valves preventing backflow. Allowing the system to be cleared, very much how a filtration device on a fish tank would work.

The ability to regulate fluid homeostasis is a key aspect of the lymphatic system. The body contains fifteen litres of lymphatic fluid, predominantly of water, and roughly 10% of proteins, hormones and waste products. Comparing this to the five litres of circulating blood that we have, the body wouldn’t contain three times more lymphatic fluid than blood if it wasn’t a critical component of our survival!

From the five litres of circulating blood, over the course of a day, three litres of plasma leaks out into the interstitial space.

If not appropriately removed through the lymphatic system this can lead to swelling outside of the cellular space due to the increased fluid concentration and alterations in pressure.

‍

Without effective drainage this can create stagnation in the fluids;
Let’s go back to the fish tank analogy above, we know that stagnation of fluids is detrimental to the ecosystem, the same being the case for our health.

In a system with appropriately functioning lymphatics, this plasma is removed from the interstitial space into the lymphatics system and circulated upwards towards the subclavian vein. This is where it flows into the venous system, before returning to the liver, detoxifying and purifying the blood.

Taking a deeper look into the pathway of the lymphatic vessels will give an understanding into the application of treating the lymphatic system.

As a one way system drains into the venous system at the bilateral sites of the subclavian veins, all lymphatic vessels are required to flow in this direction. The right upper quadrant of the body drains through the right lymphatic duct and into the right subclavian vein, whilst the remainder of the body drains through the thoracic duct into the left subclavian vein.

The thoracic duct is responsible for the majority of lymphatic flow and also houses the largest lymph node, the cisterna chyli, which is a major site of drainage for the liver. It’s crucial to keep this node functioning well as between 25-50% of the returning lymphatic fluid through the thoracic duct is returned from the liver.

There is an important bidirectional relationship between the cisterna chyli and the liver, with an overburdened liver that can’t move or function optimally placing more load on the cisterna chyli. Having a lymphatic system that can’t drain well, especially at the cisterna chyli, increases the potential to create stagnation around the liver. A lymphatic vessel that is unable to drain will not be able to receive fresh supply creating this backlog.

A fairly recent discovery reveals that the lymphatic system also continues up into the central nervous system through the glymphatics, more commonly known as the glymphatic system.

The glymphatic system has the same role as the lymphatic system, however it is only situated in the brain. This helps to reduce inflammation and drive the removal of waste products which is essential for overall brain health. Additionally, the protective benefits of this system helps to distribute fuel sources and various other vital components around the brain.
