But happiness isn’t just the outcome of achieving these goals; it’s also a catalyst for them. When we actively work to optimize our happiness, we improve our resilience, strengthen our relationships, and enhance our overall well-being, creating a positive ripple effect throughout all areas of life.
The good news? Science shows that happiness isn’t entirely out of our control. In fact, by adopting specific habits, you can make happiness a regular part of your life! Ready to lay a strong foundation for a fulfilling and joyful year ahead? Here are 10 research-backed ways to optimize your happiness in 2025.

10 Science-Backed Ways to Optimize Your Happiness
#1 Start Your Day With Gratitude
Though seemingly simple, research shows that practicing gratitude can significantly boost happiness. In fact, it can even help you live longer! Try writing down three things you’re grateful for each morning to shift your focus to positivity and train your brain to look for the good in your life. You could also keep a gratitude journal by your bed and jot down the best parts of your day before drifting off to sleep.
#2 Move Your Body Daily
Regular movement is a powerful mood booster. Exercise has been shown to increase levels of endorphins — your brain’s feel-good chemicals — while reducing cortisol, the hormone associated with stress. The result? A happier, healthier you! And, you don’t have to commit to intense workouts to gain the benefits. Even gentle movements like walking, yoga, or pilates can improve your mood, energy levels, and overall happiness! The key is staying consistent. Experiment with different workouts until you find something that works for you, then keep at it!

#3 Give Back to Others
Acts of kindness don’t just benefit the recipient — they also boost the giver’s happiness. Whether it’s volunteering, helping a neighbor, or surprising a friend or loved one with a thoughtful gesture, giving is one of the best ways to optimize your happiness and boost positivity. Challenge yourself to commit to one random act of kindness each week. It will change your life, and someone else’s!
#4 Prioritize Quality Sleep
Sleep is the foundation of nearly all processes in the body, including mental and emotional well-being. Thus, its impact on happiness is profound. Poor sleep doesn’t just leave you feeling tired — it can affect your mood, cognitive function, and ability to handle stress. In fact, research shows that consistent, high-quality sleep is directly linked to greater emotional resilience and overall happiness, while sleep deprivation can increase symptoms of anxiety, depression, and fatigue.
With this in mind, try to establish a relaxing nighttime routine and aim for 7–9 hours of sleep per night. Here are some ideas:
- Create a sleep-friendly environment by keeping your bedroom cool, dark, and quiet.
- Avoid screens at least an hour before bedtime.
- Wind down with sleep-supporting activities like reading or meditation.

#5 Minimize Screen Time
From email and Zoom to Instagram and TikTok, we’re constantly connected and on our phones. Unfortunately, excessive screen time can lead to increased anxiety, insomnia, and burnout, all of which zap joy from our lives. The good news is that studies link reduced screen time with higher levels of happiness, less loneliness, and increased mindfulness — a huge reason to put down the phone and set healthy boundaries! As best you can, try to build intentional “phone-free” hours into your day, especially before bedtime. You could even designate one day a week to go tech-free!
#6 Plan Mini Adventures
You don’t need a big vacation to experience joy — mini adventures can provide the same boost. Breaking out of your daily routine with small, spontaneous activities like exploring a new hiking trail or restaurant, hitting the road for a day trip, or trying an unusual dish creates a sense of excitement that stimulates the brain and helps you feel happier. Try to incorporate this happiness tip by planning or trying something new, even if it’s local.
#7 Think of Laughter as Medicine
Laughter isn’t just a reaction to joy — it’s also a tool for creating it. When you laugh, your brain releases endorphins and dopamine, the chemicals responsible for feelings of happiness. Plus, it helps to reduce cortisol, our stress hormone, which can help you feel more grounded and at ease. And sharing a laugh with others strengthens social bonds, a major key to long-term happiness! Even if things feel heavy, make time for humor. Maybe you watch a comedy clip, listen to a funny podcast, or share a laugh with friends. It’s one of the simplest ways to optimize your happiness.
#8 Use The “5-Minute Rule” For Tough Tasks
Overwhelming tasks can cause stress, which detracts from happiness. However, there’s a way to maintain happiness while staying productive — the 5-minute rule! It’s as simple as committing to a task for just five minutes, like tidying your space or responding to an email. Often, starting is the hardest part, and you’ll end up doing more than planned. Win-win.
#9 Get Comfortable With Saying “No”
Saying “yes” to everything can lead to overwhelm, burnout, and resentment — none of which support happiness. Learning to say “no” to obligations, events, or requests that don’t align with your values or priorities allows you to protect your energy and focus on what truly matters.
While it can feel uncomfortable at first, practice makes perfect. It could be something as simple as, “I appreciate the offer, but I don’t have the capacity right now.” Or, “Thank you for thinking of me, but I’m not able to commit right now.” Those who love and respect you will understand!

#10 Limit Exposure to Negative News
While staying informed is important, sometimes excessive news consumption is just too much for our nervous system. In fact, it can lead to stress and anxiety, and even harm our sleep! However, research shows that intentionally limiting exposure to stressful media can protect your mental health. So, do your best to limit your exposure, and avoid consuming it right before bed.
The Takeaway
Happiness isn’t just a feeling; it’s a practice. By incorporating intentional habits like moving your body daily, minimizing screen time, and setting boundaries, you can actively optimize your happiness this year. These science-backed strategies remind us that joy isn’t something we wait for — it’s something we cultivate through our choices and lifestyle.
