Physical activity can serve as a powerful tool against signs of depression. Regular exercise increases the production of endorphins and other neurotransmitters that improve mood and reduce stress. Activities like aerobic exercise, strength training, or even walking can elevate self-esteem and provide a sense of achievement. Additionally, engaging in physical activity encourages social interaction, which can further alleviate feelings of isolation. Establishing a routine can lead to significant improvements in mental health, promoting a more positive and resilient mindset.
