The Protective Power of Love in Your Brain | Juan Dominguez | TEDxUTAustin

Neuroscience & Addiction - The brain's dopamine system is activated by both naturally rewarding behaviors (like love and social bonding) and drugs of abuse, but drugs create artificial highs that are much stronger than natural rewards [16][17] - Drugs like cocaine can increase dopamine levels by 400-500%, approximately 20 times larger than the 25-35% increase observed with ejaculation, and lead to a prolonged dopamine depletion and a state of apathy [18][19][20] - Oxytocin, often referred to as the "love hormone," plays a crucial role in social bonding and can counteract the effects of stress and reduce cravings for drugs [23] - Stress is a major factor that can trigger relapse or substance use disorder [28] - Love and support from loved ones provide natural levels of dopamine and oxytocin, potentially minimizing the yearning to seek other sources of dopamine, such as illicit drugs [30][31] Social Impact & Protective Factors - Unconditional love and support can act as a protective factor against falling into negative patterns, potentially shaping the brain in ways that protect against certain risk-taking behaviors [3][10] - Oxytocin administration has been shown to reduce response to stressful stimuli, decrease cortisol levels (a marker of stress response), and decrease anxiety during social stress tests [24][25] - Oxytocin can decrease activity in the amygdala, the part of the brain that regulates fear, in the presence of stressful stimuli [26] - Love and support should be used as one mitigating factor in the battle against substance use disorder [32]
