The Brain’s 4 Feel-Good Chemicals Explained (with Dr. Bibhas Singla)
Exercise increases all 4 feel-good chemicals.
Recently, we’ve seen a surge in website clicks and phone calls from people seeking natural ways to boost the brain’s 4 feel-good chemicals: dopamine, endorphins, serotonin, and oxytocin. They may not use the exact words, but what people are looking for is neurochemical help to:
- Reduce stress
- Feel genuinely happier
- Stop relying on alcohol, drugs, sugar, or scrolling on screens
- Have more energy
- Restore balance in the brain
- Build better habits that stick
The Brain’s 4 Feel-Good Chemicals Explained
We sat down with Sanford Behavioral Health’s Chief Medical Officer, Dr. Bibhas Singla, MD, MBA, FACHE, CPE, FAPA, to get his take on the brain’s feel-good chemicals. We published an article that went viral called Dopamine Rush: 27 Things to do Instead of Scrolling, but Dr. Singla says it’s more complex than just courting dopamine. (Although putting down your phone and playing with your dog or toddler is good advice.)
Dr. Singla says, “The brain uses several different chemicals to create feelings of well-being, motivation, connection, and emotional balance. The four major players are dopamine, endorphins, serotonin, and oxytocin.” With Dr. Singla’s help, we delve into what each of these brain chemicals does and doesn’t do to enhance your mood.
Dopamine: The “Wanting” Chemical
Dopamine is a neurotransmitter (chemical messenger) in the brain that helps nerve cells communicate with each other. It drives motivation, anticipation, and the desire to seek out rewards. It reinforces behaviors the brain has previously labeled as positive. For example, when you eat an ice cream cone, your brain releases dopamine because it’s rewarding. Especially when shared with a loved one. When dopamine is activated, it is less about enjoying the experience and more about wanting it again. The goal is to be cautious about repeated rapid spikes in dopamine when used as an emotional coping mechanism.
Endorphins: The “Liking” Chemical
Endorphins, “home-grown” opioids, are natural chemicals your body releases to reduce pain and create a feeling of well-being. They are strongly linked to the “liking” side of reward through their role in creating physical pleasure. Examples include the runner’s high, feeling uplifted by music, basking in the sunlight, and engaging in outdoor activities. A belly laugh makes you feel better. Simply put, endorphins are built-in stress and pain buffers. They help you push through the discomfort by blocking pain signals and creating a sense of calm or mild euphoria. Like dopamine, caution is in order when chasing the feelings endorphins create.
Serotonin: The “Mood & Emotion” Chemical
Serotonin is a neurotransmitter that plays a major role in mood regulation. It is involved in the emotional and cognitive aspects of feeling good. Serotonin is the primary neurotransmitter increased by SSRIs, the most common antidepressants. Unlike dopamine, which tends to spike with rewards, serotonin works more like a baseline stabilizer. It helps the brain process negative outcomes and adjust behavior accordingly. Serotonin is supported by exercise, natural light, spending time outdoors, and eating complex carbohydrates. Serotonin is essential for emotional stability, but balance matters. Both deficiency and excessive levels (usually from medication interactions) can cause problems such as depression, anxiety, and sleep disruption.
Oxytocin: The “Connection & Relaxation” Hormone
Oxytocin is a hormone and neurotransmitter that helps create trust, bonding, and emotional connection. Often called the “love” or “cuddle” hormone, it helps create feelings of safety, social connection, and feeling rewarded in social situations. Oxytocin is boosted by physical touch, exercise, emotional safety, and positive social interactions. However, even the cuddle hormone needs to be balanced. Oxytocin strengthens social and emotional bonds, but it can also deepen attachment even when relationships are unhealthy.

The Role of Exercise in Boosting and Balancing Feel-Good Brain Chemicals
According to Dr. Singla, “Exercise is one of the most reliable ways to support the brain’s natural feel-good chemistry because it activates several systems at once. Exercise does not have to be intense. The goal is to meet yourself where you are; being outdoors adds benefit to exercise through sunlight, movement, and sensory stimulation. Most people think of exercise for their body, but I think of exercise of the mind. The physical benefits are the cherry on top, but the mental health benefits are the main course.”
Dr. Singla practices what he preaches. As an avid scuba diver, he activates many of the same systems we talk about in mental health treatment at Sanford Behavioral Health. Scuba diving increases dopamine through exploration, serotonin through rhythmic breathing, endorphins through physical challenge, and oxytocin through the scuba buddy system. Dr. Singla’s exercise of choice is a powerful reminder that the brain thrives in environments that balance novelty with regulation.
Bringing It All Together
Well-being does not come from a single happiness chemical or dopamine dive. It comes from the balance of several brain chemicals working together to support motivation, resilience, calm, and connection. Dr. Singla says, “When we talk about the brain’s feel-good chemicals, the goal is not to chase one of them in isolation. Activities such as exercise, time in nature, meaningful relationships, and even an immersive pursuit like scuba diving support a natural sense of balance. At Sanford Behavioral Health, mental health is not only about reducing symptoms but about supporting the brain’s natural equilibrium.”
