Bisphenol-A (BPA) is a synthetic compound used in plastics and containers
Bisphenol-A (BPA) is a synthetic compound with a carbon base, commonly used in the manufacturing of polycarbonate plastics, epoxy resins, and food and beverage containers. It is a known endocrine disruptor, exerting a wide range of metabolic effects on the human body. BPA exposure has been linked to reproductive and thyroid hormone dysregulation, weight gain, glucose intolerance, insulin resistance, type 2 diabetes, metabolic syndrome, cardiovascular disease, and fatty liver disease.
Recent studies have also explored the relationship between BPA levels and sleep adequacy in adults, suggesting a potential link between BPA exposure and sleep duration, as well as sleep problems and disorders.
While the specific mention of BPA in sleeping bags is scarce, there is growing concern about the presence of BPA in clothing and fabrics. BPA has been detected in polyester-based clothing, including athletic wear and socks made for infants. This is concerning because BPA can be absorbed through the skin and enter the bloodstream. When individuals sweat in these garments, the BPA-laced perspiration can be absorbed back into the skin, increasing exposure.
However, some sleeping bag options explicitly advertise themselves as BPA-free. For example, Wildkin offers sleeping bags for children that are made from a blend of cotton and polyester materials and are marketed as BPA-free. This suggests that there may be a growing awareness in the industry about the potential presence of BPA in sleeping bags and a subsequent effort to create BPA-free alternatives.

BPA is an endocrine disruptor with estrogenic activity, impacting metabolism and reproduction
Bisphenol-A (BPA) is a synthetic compound that has been used since the 1950s in the manufacturing of polycarbonate plastics and epoxy resins, food packaging, industrial materials, dental sealants, and personal hygiene products. Due to its widespread use, human exposure to BPA occurs through skin contact, inhalation, and the digestive system. BPA is particularly concerning because it is an endocrine disruptor with estrogenic activity, which means it can interfere with the body's hormones and have a range of metabolic and reproductive impacts.
As an endocrine disruptor, BPA can bind to estrogen receptors in the body, such as ERα and ERβ, and mimic or block the action of endogenous sex hormones. This interference with the body's natural hormone balance can lead to a variety of health issues. For example, studies have suggested a link between BPA exposure and reproductive issues, including testicular dysgenesis syndrome, cryptorchidism, cancers, and decreased fertility in males, as well as follicle loss in females. BPA exposure has also been associated with an increased risk of hormone-related cancers, such as ovarian, breast, prostate, and colon cancer.
In addition to its impact on reproduction, BPA can also affect metabolism and contribute to weight gain, glucose intolerance, insulin resistance, type 2 diabetes, metabolic syndrome, cardiovascular disease, and fatty liver disease. The complex relationship between BPA exposure and health outcomes is an active area of research, with emerging evidence suggesting that BPA may have negative health effects beyond those already identified.
While this information highlights the potential dangers of BPA exposure, it is important to note that the specific context of sleeping bags in relation to BPA was not directly addressed in the sources. However, given that BPA is commonly found in polycarbonate plastics and epoxy resins, it is possible that some sleeping bags could contain these materials, leading to potential exposure during sleep. Nonetheless, further investigation would be needed to determine the specific presence of BPA in sleeping bags and the associated health risks, if any.

Studies show BPA can be absorbed through the skin and enter the bloodstream
Bisphenol-A (BPA) is a carbon-based synthetic compound used in the manufacturing of polycarbonate plastics, epoxy resins, and food and beverage containers. It is a ubiquitous endocrine disruptor with estrogenic activity and is known to exert a wide variety of metabolic effects. Recent literature reviews have pointed out the heterogeneity of epidemiologic evidence linking BPA exposure to various health outcomes.
A study by Frederick vom Saal of the University of Missouri-Columbia, along with Annette M. Hormann and colleagues, found that large amounts of BPA can be transferred to your hands and then to the food you eat, and can also be absorbed through the skin. The study found that in the presence of chemical hand sanitizers, there was an increased absorption of BPA into circulation.
Another study published in PubMed measured and characterized skin absorption for BPA through ex vivo human skin using flow-through diffusion cells. The study found that BPA can migrate onto the skin and be absorbed when handling thermal papers, such as cash register receipts, labels, and tickets. The study also found that BPA was absorbed more than its alternatives, such as Bisphenol S (BPS), D-8, and Pergafast 201® (PF201).
These studies suggest that BPA can be absorbed through the skin and enter the bloodstream, with potential negative health effects. While the primary route of exposure to BPA is through oral intake, it is important to consider other potential sources of exposure, such as dermal contact and the handling of receipt paper.

Wiggy's sleeping bags are PFAS/PFCs-free, flame retardant-free, and made in America
Bisphenol-A (BPA) is a carbon-based synthetic compound used in the manufacturing of polycarbonate plastics, epoxy resins, and food and beverage containers. Although BPA has been linked to various health issues, there is little research on its effects as an endocrine disruptor on sleep. A study evaluating the relationship between BPA levels and sleep adequacy in US adults hypothesized that BPA levels are inversely related to sleep duration and negatively impact sleep problems and disorders.
PFAS/PFCs (polyfluoroalkyl substances/perfluorinated chemicals) are fluorinated compounds known as "forever chemicals" due to their persistence in the environment. They are commonly used in durable water repellent (DWR) coatings on fabrics, including some sleeping bags. However, PFAS/PFCs have been phased out by some companies due to health and environmental concerns.
Flame retardants are another chemical commonly found in sleeping bags. These chemicals are added to fabrics to inhibit the spread of fire, but they can also pose health risks. Wiggy's sleeping bags are naturally free of dangerous sprayed-on fire retardant chemicals, making them a safer option for consumers concerned about the potential health impacts of these substances.
When choosing a sleeping bag, it is important to consider the materials used and their potential impact on your health and the environment. PFAS/PFCs and flame retardants are just two types of chemicals that may be present in sleeping bags, and consumers should research and ask manufacturers about the specific chemicals used in their products.
