Frequently Asked Questions
Our team continues to share evidence-based stories that promote the establishment of healthy routines.
Why do we emphasize this point?
Firstly, habits like maintaining a balanced diet, engaging in daily physical activity, managing stress, and prioritizing sleep have all been shown to reduce the risk of age-related illnesses and increase the likelihood of a long and healthy life.
An example of this is our article on Seven Easy Habits to Stop Dementia. We discussed a significant study that revealed how certain lifestyle choices could potentially cut the risk of dementia by almost half! Impressive, right?
However, forming positive habits and breaking negative ones can be a challenge for everyone. That's why we've delved into the science of habits and will provide practical tips to help you turn your intentions into actions.
Is it true that it takes 21 days to develop a habit?
You might have heard that it takes 21 days to form a habit. But where did this idea originate? Some attribute it to a book called "Psycho-Cybernetics" by Maxwell Maltz, published in 1960.
As with many myths, there is some truth that has been misinterpreted.
Maltz mentioned: “These, and many other commonly observed phenomena, tend to show that it requires a minimum of about 21 days for an old mental image to dissolve and a new one to gel.”
And so, the 21-day myth was born.
Fortunately, researchers were skeptical. A study in 2009 found that it takes anywhere from 18 to 254 days for a new habit to form. On average, it takes about 66 days for a behavior to become automatic.1
Fast forward to 2023, and researchers are still exploring the concept of habits. Social scientists at the California Institute of Technology determined that there is no set time frame for habit formation.2
"You may have heard that it takes about 21 days to form a habit, but that estimate was not based on any science," stated co-author Dr. Colin Camerer. "Our work indicates that the speed of habit development varies depending on the behavior and other factors."
Evidently, there is no universal timeline for adopting healthy behaviors. But why is it so challenging? It appears that our approach may be flawed.
Often, we make unrealistic resolutions to start exercising or losing weight without setting ourselves up for success.
Tara Parker-Pope explored this topic in an article for the New York Times.3 The author provides research-supported tips to enhance your chances of success.
Experts recommend connecting a new habit to an existing one. Identify daily routines and find a way to integrate a new habit. For instance, if you have a morning coffee ritual, consider adding a one-minute meditation session. Or, while brushing your teeth, incorporate a few squats or practice balancing on one foot.
Interested in exercising more? Begin with small steps. Instead of aiming for a marathon, commit to a brief daily walk. The same principle applies to eating well; opt for fruits and vegetables with each meal rather than diving into a restrictive diet.
Rewards play a crucial role in habit formation. However, the benefits of healthy habits, like improved health or fitness, may not be immediate. To help establish a habit, it's beneficial to include immediate rewards. Parker-Pope suggests listening to audiobooks while exercising or watching a favorite cooking show while on the treadmill to reinforce the habit. Additionally, scheduling a workout with a friend can be motivating.
My suggestion?
The initial step is often the most challenging, but cultivating healthy habits leads to further positive changes. For example, once a daily walk becomes a routine, you may find it easier to nourish your body with nutritious foods.
With time, commitment, and repetition, healthy habits will gradually form. It's important to be patient and anticipate obstacles along the way. Dr. Susan Czajkowski, an expert in behavioral change from the National Institutes of Health, acknowledges that setbacks can be discouraging.
“The encouraging news is that years of research demonstrate that change is achievable, and there are effective strategies to help you set yourself up for success,” notes the doctor.4
Establishing positive habits is a long-term endeavor. Nevertheless, making healthy choices can significantly reduce the risk of health issues such as heart disease, stroke, cancer, type-2 diabetes, and obesity.
