    The self-care industry: a $6.8 trillion market versus the evidence

    The Global Wellness Institute estimates the wellness economy reached US$6.8 trillion in 2024, with "mental wellness" spending of US$268 billion among its fastest-growing parts.[1][2] The self-care steps with the best evidence, such as exercise, sleep and social connection, cost little, while popular paid categories like meditation products rest on weaker research and light regulation.[3][4][5]

    Self-care is now a large consumer market.[1] This analysis compares where the money goes with where the evidence is, and explains why regulators rarely test wellness claims. It does not rate individual products; for that, see the sleep and mood tracker guide and the meditation apps buyer’s guide. It is general information, not medical advice; talk to a clinician about your own health.

    How big the market is

    The Global Wellness Institute (GWI), an industry research nonprofit, estimated the global wellness economy at US$6.8 trillion in 2024, up 7.9% on 2023.[1] It put “mental wellness” at US$268 billion and named it the second-fastest-growing sector, with the US market alone worth US$125 billion.[2] The fastest-growing mental wellness segments over five years were cannabis products, meditation and mindfulness, and sleep.[6] Workplace wellness was the one sector without significant growth.[7]

    GWI forecasts growth of about 7.6% a year, to roughly US$9.8 trillion in 2029.[8] This is an industry body’s projection, and GWI’s definitions are broad, covering sectors such as wellness real estate and spas alongside mental wellness.[9]

    Where the evidence is

    The best-tested self-care steps are inexpensive. A 2024 BMJ review of 218 trials found exercise an effective treatment for depression, though with low or very low certainty because of trial quality.[3][10] A meta-analysis of 65 trials found that improving sleep improved mental health, with medium-sized effects.[11] Stronger social relationships were linked with 50% better odds of survival in a meta-analysis of 148 observational studies.[12]

    For meditation and mindfulness, among the fastest-growing paid segments, the NIH’s National Center for Complementary and Integrative Health says much of the research has been preliminary or not scientifically rigorous.[4] It also reports a review in which about 8% of participants had a negative effect.[13]

    The mismatch is not that paid products never work; some are delivery methods for habits with evidence behind them. It is that the categories growing fastest in spending are not the ones with the strongest trial evidence, and marketing rarely says how strong the evidence is. Readers can ask of any product: what was it tested against, in whom, and who paid for the study?

    How lightly it is regulated

    In the US, the FDA treats claims about relaxation or stress management and about tracking sleep trends as “general wellness” claims, outside its medical device oversight.[5] Its guidance even gives an example of an acceptable claim that a product tracking sleep, work and exercise “may help living well with anxiety”.[14] A revision issued in January 2026 loosened oversight further: MedTech Dive reported it means blood pressure estimates used for wellness need not be regulated as medical devices.[15]

    A dispute with the wearable maker WHOOP spans the change. In July 2025 the FDA warned the company that its Blood Pressure Insights feature was marketed without clearance; in June 2026, after the new guidance, it closed the letter once WHOOP had modified the feature.[16][17]

    Privacy is a separate gap. A 2019 study of 36 top-ranked depression and smoking-cessation apps found 33 sent data to third parties, often to Google or Facebook, and frequently without saying so in their policies.[18]

    Light regulation keeps prices down and lets useful tools reach people quickly. The trade-off is that the burden of judging claims and privacy falls on consumers, who often lack the information to do so.

    What may change

    With GWI projecting continued growth and the FDA’s January 2026 policy favouring lighter oversight, more wellness features that estimate body signals are likely to reach the market without device review. Whether regulators respond with stronger privacy rules for health data, rather than device rules, is an open question. Spending on services will remain the larger determinant of mental health outcomes: WHO reports median government mental health spending of 2% of health budgets, unchanged since 2017.[19]

    Competing views

    The market meets real demand

    Growth reflects genuine need: WHO counts 1.2 billion people with mental disorders and most lack effective care, so low-cost apps, trackers and programmes can widen access to habits with evidence behind them, such as exercise and better sleep.[20][21][3][11]

    Marketing outruns the evidence

    Fast-growing categories such as meditation and mindfulness products lean on research NIH's NCCIH calls largely preliminary, while FDA's wellness policy lets products make stress and sleep claims without proving them as medical devices.[6][4][5][14]

    Self-care cannot replace care systems

    Public-health bodies stress that the biggest gaps are in services: median government mental health spending is 2% of health budgets, and employers' workplace wellness spending is the one sector GWI found stagnant.[19][7][22]

    Questions readers ask

    How big is the wellness industry?

    The Global Wellness Institute, an industry research nonprofit, estimated the global wellness economy at US$6.8 trillion in 2024, up 7.9% on 2023, and forecast about US$9.8 trillion by 2029.[1][8]

    What is the "mental wellness" market?

    GWI put the mental wellness segment at US$268 billion in 2024, with the US market at US$125 billion; its fastest-growing parts were cannabis products, meditation and mindfulness, and sleep.[2][6]

    Are wellness apps and trackers regulated by the FDA?

    Mostly not as medical devices. Under FDA's general wellness policy, claims about stress management or tracking sleep trends are treated as general wellness claims, and a January 2026 revision loosened oversight further.[5][15]

    Which self-care habits have the best evidence for mental health?

    Exercise and improving sleep have the most randomised-trial evidence; a BMJ review found exercise effective for depression, and a meta-analysis of 65 trials found better sleep improved mental health.[3][11]
