What natural things can i do to increase dopamine?

Pleasurable: Pleasurable activities, foods, exercises, images, drinks (careful, i don t mean necessarily "those"...), even sex. Those things you enjoy the most, increase your dopaminergic activity. Wherever your passion is, like my brother says. That is in general. Now, in presence of a disease (like parkinsons), the whole mechanism lacks enough neurotransmitter to make this ideas effective. Consult your dr.
