What Causes ‘Mood Swings’ in People?

Sometimes people go from happy to sad or angry really quickly. This happens because of hormones and chemicals in the brain, like serotonin and dopamine. Imagine your brain is like a seesaw: when one side goes up, the other goes down. That’s what makes mood swings happen. A little stress, tiredness, or even a change in weather can tip the seesaw!
