How Feelings of Joy Affect
Your Body Physically 1. Your brain. When you're happy, your brain releases dopamine and serotonin into your
central nervous system. This tells your
whole body that you feel good. 2. Your circulatory system. Dr. Diana Samuel, via Healthline Joy isn't the only emotion to affect this system, however. Fear, sadness and
other emotions take their turns as well. 3. Your autonomic
nervous system. This is your bodily system that works without your conscious effort.
Things like breathing and
digestion are handled with this system. It can be affected by joy,
for example, with rapid breathing, salivation, sweating, body
temperature and metabolism.
