As I mentioned in a previous newsletter, the role of dopamine in mental fitness is crucial for motivation, focus, and goal setting. Since then, in Assembly I have discussed other important chemicals in our brain, Oxytocin, Serotonin, and Endorphins, each contributing in their own way to our overall wellbeing. These chemicals, often referred to as "feel-good" hormones, have significant impacts on how we feel, think, and interact with others.

The level of these chemicals are activated in different ways. Oxytocin helps build trust and connection between people (and pets) and is activated by touch such as handshakes, high fives, playing with a dog, meaningful conversations, or working as part of a team. Serotonin plays a key role in regulating our mood and having balanced serotonin levels is linked to feelings of happiness. Physical activity, particularly outdoor exercise, helps stimulate serotonin production.

Endorphins are the body's natural painkillers, and they're responsible for the euphoric feelings we experience after exercise, laughter, or even eating certain foods. Engaging in physical activity is one of the best ways to release endorphins.

The literature around mental health in adolescents makes links to screens and online activities as a main contributing factor to wellbeing issues. The combination of less human connection, less physical activity and less time outside all reduce the production of these hormones. I ended last assembly by asking students to reflect on the types of activities they do in their free time and consider if they should make changes to their routines.
