Touch and embrace.
What happens: To us, humans, social interaction is really important. Various forms of physical support, especially touches and embraces, can speed up a person’s recovery after an illness. If you remove tactile interaction from your life, the brain perceives its absence the way it perceives physical pain: the same brain zones become activated in both instances. This, in turn, triggers the processes that affect your mood and contribute to the development of depression.
Learn, learn, and, once again, learn!
What happens: For the brain, acquiring new knowledge means permanent adaptation to a changing environment. By means of this process, our brain develops, rewarding its own attempts to absorb and process fresh information with dopamine, the hormone of joy. If you want to be happy, don’t be afraid to try something new, to change your surroundings, to learn new things.
