Physical health and wellness play a crucial role in managing depression. Regular exercise releases 'feel-good hormones' or endorphins that can boost your mood. A balanced diet, rich in fruits, vegetables, lean protein, and whole grains, can impact your mood and energy levels. Adequate hydration can prevent feelings of fatigue, and proper sleep hygiene can help manage depression symptoms. Additionally, avoiding alcohol and drugs, practicing relaxation techniques, and getting regular sunlight can contribute to overall mood improvement.
