When you are dancing, your body is fully in that moment, focused on the music and your surroundings. Being around friends or that someone special to enjoy dancing to your favorite music can help you focus on strictly the moment you are in and aid in reducing the amount of cortisol your brain produces (the hormone that is associated with stress), lowering your stress and tension levels.
Disclaimer: As a professional dancer, you need to prioritize discipline and consistency in your training. Do take care of your body through proper warm-ups, stretching, and conditioning, because longevity in dance depends on maintaining strength and preventing injuries. Do stay versatile by exploring different styles, since adaptability opens more opportunities and keeps your artistry fresh.
