Many people are intrigued by the idea of forming better habits—whether it’s waking up earlier, exercising consistently, or simply finding time to unwind. While the concept of healthy habits is appealing, actually making them stick is where most people struggle. Despite good intentions, daily life often gets in the way, and the gap between what you want to do and what you consistently end up doing instead can feel frustratingly wide.
That’s where habit stacking comes in. This practical, science-backed strategy helps bridge that gap by linking new behaviors to ones you already do without thinking—making habit change feel more natural, more sustainable, and far less overwhelming.
If you are interested in habits, including how long they take to form, how they can be broken, and how to stick to them, as well as the power of habit stacking, plus how to include a soak in your Jacuzzi® Hot Tub as part of a habit stack, this article will guide you through everything you ever wanted to know about habits.
What is habit stacking?
At its core, habit stacking is a simple, science-backed strategy that helps you create new, beneficial routines by attaching them to habits you already do consistently. James Clear popularized the concept in his bestselling book Atomic Habits, where he described habit stacking as a way to make behavior change easier by leveraging the power of existing routines.
Rather than trying to overhaul your life overnight—which often leads to failure—habit stacking helps you build change gradually and sustainably. For example, if you already make a cup of tea each evening, adding 5 minutes of deep breathing right after could be the beginning of a new relaxation ritual.
This approach is especially effective for wellness because it allows you to incorporate supportive practices—like mindfulness, movement, or hydrotherapy—into your day without requiring a total lifestyle makeover.
The science of habit formation: How long does it take to form a habit?
Before getting into the details on how habit stacking can be used to break bad habits and establish healthy new ones, it’s helpful to understand how habits work.
Contrary to the popular belief that it takes 21 days to form a new habit, experts say that it might take some people longer than that, while others may be able to form a habit in even less time. An article titled “How Long Does It Really Take to Form a Habit?” on the Scientific American website states that everyone has a unique habit-building timeline—and no matter how long it is for any individual, repetition is the key to making it work.
This is explained by Phillippa Lally, a senior lecturer in psychology and the co-director of the Habit Application and Theory group at the University of Surrey in England.
Generally, however, the article suggests habit formation can range from a few weeks to a couple of months. Furthermore, it cites a study on habit creation that found habits developed in a range of 18 to 254 days, with the average time being 66 days.
It’s crucial to understand that missing a day here and there won’t entirely derail your process—consistency over time matters more than perfection. So don’t give up if you get slightly off track as you work toward your new habit.
