Rewards can help you start a healthy habit, but the wrong ones can backfire: food rewards that undo your effort, big prizes that make the habit feel like a chore, or all-or-nothing goals that collapse after one miss. Good rewards are small, immediate, matched to the behaviour you control, and gradually replaced by the satisfaction of the habit itself. Here is how to design them.
Why rewards help, and how they backfire
New habits often feel like effort with no payoff. The benefits of more walking or better sleep build slowly, but the cost (time, effort, giving up something easier) is felt right away. A reward bridges that gap by giving you something good now.
There is some evidence this works. A 2015 meta-analysis of 34 trials found that personal financial incentives increased health behaviour change in areas such as eating, physical activity and smoking, with effects lasting up to 18 months and for a few months after the incentives stopped. The authors also noted that the overall impact on disease may be limited.
Rewards can backfire in several common ways:
- The reward works against the goal. A large dessert for a week of healthy eating, or a “cheat day” that becomes a binge.
- The reward is too far away. A holiday in six months does little to get you off the couch tonight.
- The reward is tied to outcomes you cannot control. Rewarding a number on the scale can lead to frustration when water weight shifts, or to unhealthy shortcuts.
- The reward replaces your own reasons. If the only reason you walk is to earn a prize, the habit can fade when the prize ends.
Rule 1: Reward the behaviour, not the result
You control your actions. You do not fully control your weight, your step count on a rainy week or how well you sleep on a given night. Reward the things you do:
| Instead of rewarding | Reward |
|---|---|
| Losing 2 kg | Packing lunch 4 days this week |
| Hitting 10,000 steps | Taking your planned after-dinner walk |
| A perfect sleep score | Screens off at your set time 5 nights |
| A smaller clothing size | Completing 8 strength sessions this month |
Outcome goals still have a place for direction. Just keep the rewards on the actions.
Rule 2: Make rewards immediate and small
The closer a reward is to the behaviour, the more it helps. Small, frequent rewards usually beat one large distant one.
Immediate rewards (right after the habit)
- Checking off a box or adding a sticker to a calendar
- Listening to a favourite podcast or audiobook only during walks
- A warm shower and comfortable clothes after a workout
- A few minutes of quiet time with a cup of herbal tea
Short-term rewards (end of the week)
- A new book, magazine or puzzle
- Time for a hobby you enjoy
- A trip to a park, beach or trail you like
- Putting a set amount into a “habit jar” toward something you want
Milestone rewards (after a month or more)
- New walking shoes or workout gear
- A class, lesson or experience
- A day trip
Rule 3: Keep rewards aligned with the goal
A reward should support the person you are trying to become, not undo the work. Avoid using food, especially large treats, as a regular reward for eating well or exercising. It links “healthy” with “deprived” and “treat” with “earned,” which can make eating feel like a constant trade. Enjoy treats on their own terms, not as payment.
Rewards that add to your health or wellbeing, such as better gear, time outdoors or something that makes the habit more pleasant, tend to work best.
Rule 4: Build your own reasons alongside rewards
Long-term, external rewards matter less than your own motivation. A systematic review of 66 studies on exercise motivation found consistent support for a link between more self-driven forms of motivation and exercise, with intrinsic motivation (enjoying the activity itself) more predictive of long-term adherence. Feeling capable also predicted participation.
Ways to build that alongside rewards:
- Choose activities you enjoy. If you dislike running, do not reward yourself for running. Find movement you look forward to.
- Notice how you feel. After a walk or a good night’s sleep, take a moment to name the benefit: more energy, a clearer head, a better mood.
- Track progress in skills. Lifting a little more, walking farther or cooking a new recipe builds a sense of competence.
- Write down your reasons. Keep a short list of why these habits matter to you and read it when motivation dips.
Rule 5: Avoid all-or-nothing reward rules
“If I work out every day this month, I get new shoes” sounds motivating until you miss day six. Then the reward is gone, and so is the reason to keep going. Build in flexibility:
- Use targets like “4 out of 7 days” instead of “every day.”
- Count points across the week so one missed day does not end the streak.
- Allow a “never miss twice” rule: one miss is fine, just get back on the next day.
Rule 6: Fade rewards over time
Once a habit feels automatic, you can reduce the rewards. Move from daily to weekly rewards, then to monthly milestones, then let the habit carry itself. Keep celebrating meaningful milestones, though. Our article on celebration design has ideas for marking wins in a way that strengthens your identity as someone who takes care of their health.
A simple reward plan template
- Habit: What specific action are you rewarding?
- Target: How often, with built-in flexibility?
- Immediate reward: What happens right after?
- Weekly reward: What do you get for meeting the target?
- Your reason: Why does this habit matter to you?
- Review date: When will you check whether the reward still helps?
Shared rewards and accountability
Some people find rewards work better with others involved. A friend, partner or family member can share a goal and a reward, such as a weekend hike once you have both met your walking target. Keep the same rules: reward actions, keep targets flexible and choose rewards that support health. Our article on the habit buddy system covers how to set this up without it turning into pressure.
Quick takeaways
- Reward actions you control, not outcomes like weight.
- Use small, immediate rewards plus occasional larger milestones.
- Choose rewards that support your goals, and avoid using food as payment.
- Build your own reasons so the habit lasts after rewards fade.
- Use flexible targets so one missed day does not end the plan.
FAQ
Are rewards childish for adults?
No. Most adults respond well to clear, small rewards, especially early in a new habit. The key is choosing ones that fit your goals.
What if I stop doing the habit when the rewards end?
Fade rewards gradually and focus on what you enjoy about the habit. If it still stops, the habit may need adjusting to suit you better.
