We all know that healthy habits—like exercising regularly, eating nutritious foods, staying hydrated, and taking care of our teeth—are essential for long-term well-being. But making these behaviours stick can be challenging. You may have heard that it takes just 21 days to form a habit, but research shows the process is far more complex and varies from person to person.
How Long Does It Really Take to Form a Habit?
A review of 20 studies involving 2,601 participants looked at different health-related behaviours, including exercise, reducing screen time, drinking more water, eating healthier, and flossing. The results showed that it takes between 59 and 66 days to form a habit, but the timeline can range anywhere from 4 to 335 days, depending on the behaviour and individual.
Several key factors influence how quickly and effectively a habit is formed:
The Three Stages of Habit Formation
Habit formation doesn’t happen overnight—it typically follows three key stages:
1. Deciding to Take Action
The first step is to make a conscious decision to start a new habit. This could be as simple as drinking more water each day or exercising three times a week. Research shows that when people choose habits that align with their personal goals, they are more likely to stick with them.
2. Repeating the Behaviour
Consistency is key. The more often you repeat a behaviour in a stable context, the more natural it becomes. Early repetitions have the biggest impact on making an action feel automatic, so sticking with it—especially in the first few weeks—is essential.
3. Making the Behaviour Automatic
The final stage is when the behaviour becomes second nature—you do it without even thinking. Enjoyment, planning, and small preparations (like setting out workout clothes the night before) help make the habit feel effortless. While some habits take longer to solidify than others, the key is persistence.
Making Habit Formation Easier
Forming a habit takes effort, but there are ways to make it easier:
The process of building a habit is different for everyone. Some people may develop new habits quickly, while others need more time. But with patience, repetition, and the right approach, healthy behaviours can become an effortless part of your daily life.
