Have you ever wondered why stepping outside instantly increases your mood? The answer lies in serotonin, dopamine and endorphins. Our brain’s chemistry determines how we feel, and these neurotransmitters all work together to regulate mood, reduce stress and improve overall well-being.
Often referred to as the “feel-good” neurotransmitter, serotonin contributes to feelings of happiness. When we are exposed to sunlight, serotonin production is stimulated. Ultraviolet (UV) rays trigger the release of vitamin D, which helps to increase serotonin levels. Those frequently exposed to the sun have higher serotonin levels, making them feel calmer and more focused. Seasonal Affective Disorder (SAD), the winter blues that so many of us experience, is much more common in the winter when sunlight is rare.
Dopamine is a neurotransmitter connected to your reward and motivation system. When doing something enjoyable, a large amount of dopamine is released. Having the right balance helps you feel motivated, happy, alert and focused. Dopamine is released when you try new things, accomplish goals or exercise. Being outside and experiencing nature is a great way to increase your dopamine levels because it provides countless opportunities for excitement, like going on a scenic hike, watching a vibrant sunset or playing in the snow.
Endorphins are created in the brain and carry signals across your nervous system, essentially blocking pain. They are natural pain relievers that help you feel better and put you in a positive state of mind. Endorphins are released during physical activity such as running, swimming or biking, as well as listening to music and engaging in other activities that you enjoy. If you want to increase your endorphins even more, exercising outdoors gives an extra boost because sunlight triggers the release of endorphins.
Incorporating more time spent outdoors into your daily routine is an easy yet impactful way to improve your mental and physical health. Not only does spending time outside improve your mood, but it also benefits your body. Sunlight is a natural source of vitamin D, which is essential for bone and muscle health, immune function and strength. Nature gives a boost to serotonin, dopamine and endorphins, keeping us happy.
“It is important to remember that, in psychology, no single study proves anything rather, it is when studies are replicated with similar results, and a pattern of similar findings on related topics is found that we can say there may well be at least a correlation between time in nature and reduced stress in some form,” said IB psychology teacher Craig Hausman.
Hausman also added that he likes to exercise, which is known to boost neurotransmitters as a way to improve mood.
Ultimately, by spending more time outdoors and engaging in physical activity, we can naturally enhance our well-being, reduce stress and maintain a happier, healthier lifestyle.
