Bad habits are hard to kick. Once they are in your routine, they seem as natural as brushing your teeth. But research has found that there are reliable ways that can help loosen their hold. Many are easier than you might think. Here are nine common bad habits people have and the science-backed ways to break them.

Smoking – Use if-then planning

Quitting smoking is one of the most difficult habits to break. This is because nicotine creates very powerful cravings. Most of the time, sheer willpower is not enough to overcome these. Which is why experts recommend “if-then” planning. For instance: “If I get the urge to smoke after lunch, then I’ll chew gum instead.” This provides your brain with a pre-made response.
Social media addiction – Try a dopamine detox

Ever notice how simple it is to lose yourself in scrolling? Hours pass, and then you feel anxious. That is your brain adapting to regular dopamine hits from social media. A dopamine detox is a method of hitting the brakes.
It doesn’t mean no fun, only less stimulation. Even a pause of an afternoon can aid your brain to recalibrate. Many people who try it say they feel more centered, and able to focus on what truly matters.
Overeating junk food – Change your environment

We are all creatures of habit. Most of us will eat what is in front of us first. The bag of chips is staring you down? You will grab it without thinking. Research has shown that one of the easiest ways to combat this is to change your surroundings. Keep fruit visible. Put snacks on a high shelf or simply don’t buy them at all. These small changes can be the difference between giving in and moving on.
Excessive drinking – Use habit stacking

Many drinking habits are tied to routine—you come home from work, grab a drink, and it becomes automatic. Habit stacking offers a way out. You simply replace that slot with a healthier ritual. For example, “After work, I’ll pour tea instead of alcohol” or “When I feel like drinking, I’ll go for a short walk.” By attaching the new behavior to something you already do daily, you build consistency and weaken the old drinking cue.
Nail-biting – Decoupling technique

Lots of people bite their nails when they’re stressed or bored. But this habit can seriously damage both teeth and nails. You may think quitting is a test of willpower alone. But experts say try decoupling instead. It means substituting a different motion, like clenching a stress ball or rubbing your fingers. The new habit breaks the automatic pattern and reconditions your brain to respond. Eventually, the new response will become your default.
Overspending / Shopping addiction – Use visual reminders

Impulse buying can feel exhilarating but is often followed by guilt. An evidence-based strategy is to use visual reminders to stop yourself in your tracks. For example, write on your card “Do I really need this?” or post your savings goal where you can see it. Research shows that the simple act of seeing these cues helps you think before you buy.
Sedentary lifestyle – Competing response trick

Hours spent sitting at your desk or in front of the television can silently damage your health. Counteract this pattern by using a competing response. Stand up and stretch whenever you begin to feel restless, or set an hourly alarm that reminds you to walk. Training movement to be your automatic response to long stretches of sitting will balance out the negative impact.
Negative self-talk – Practice self-compassion

Making mistakes is human nature, but beating yourself up gets in the way of bouncing back. Self-compassion is one of the best ways to break the cycle of negative thinking. So how do you treat yourself when things go wrong? Try speaking to yourself with patience and kindness as you would with a friend.
Research shows that self-kindness after failure actually helps people recover more quickly. Plus, it seems to be linked with healthier habits and better stress management.
Procrastination – Gamify your tasks

Everyone procrastinates. It often begins with small tasks, until one day you can’t avoid it anymore. A more enjoyable way to combat it is to gamify your tasks. You can think of finishing small goals like adding points to your score, or create streaks and micro-challenges to reward yourself and keep going. Studies suggest gamifying work increases interest. Even something as simple as checking things off a list can create progress.
