Legal & disclaimer
Information only. Everything on Habitualism is general information. It is not medical or health advice, and using this site does not create a doctor–patient or any other professional relationship.
Reported, not recommended. Routines are summarised from public sources such as podcasts, books, articles and the person’s own posts. They may be out of date, incomplete or inaccurate, and what suits one person may not suit you.
No endorsement. The people featured have not reviewed or endorsed this site or any product on it.
Your own risk. If you follow any routine or part of one, you do so at your own risk. Talk to your doctor before changing your diet, exercise, sleep, supplements or medication. To the extent permitted by law, we accept no liability for any loss, injury or damage arising from use of this site.
In an emergency, contact your local emergency number or go to the nearest emergency department straight away.
Affiliate links. Some links are affiliate links: we may earn a commission at no extra cost to you. This never decides what goes in a routine.
Health information and risks
General information only. Routines here are summaries of what people say they do, taken from interviews, podcasts, posts and their own sites. They have not been checked or verified by medical professionals, and they may be out of date: people change their routines, and sources can be edited or removed.
Talk to a doctor first. Before changing your diet, exercise, sleep, supplements or medication, talk to a doctor and get any tests they recommend, especially if you are pregnant, breastfeeding, taking medication or have a health condition.
Specific risks. Some practices described on this site carry particular risks:
- Breathwork with breath holds can cause fainting. Never do it in or near water, while driving, or standing where a fall could hurt you. Take care if you have heart or lung conditions.
- Cold and heat exposure (cold plunges, cold showers, sauna, cryotherapy) puts strain on the heart and circulation and isn’t suitable for everyone.
- Fasting, skipped meals and restrictive diets (including all-meat diets) can cause side effects and aren’t suitable for everyone, including anyone with a history of disordered eating.
- Supplements can interact with medicines and with each other, and quality varies. We list names only, never doses. What someone takes is not a recommendation for you. Some, such as melatonin, are prescription-only in some countries, and we leave prescription medicines out entirely.
- Skincare actives such as exfoliating acids can irritate skin. Patch-test, and ask a dermatologist if unsure.
- Sun. Morning-light habits never mean looking directly at the sun.
Brands and sponsors. Where we know that someone sells their own products, or is paid by or partnered with a brand they mention, we say so on their page and don’t link that brand. We may not know every relationship.
