According to modern science, happiness is caused by brain chemistry, in particular the chemicals Dopamine, Oxytocin, Serotonin and Endorphins. (Each of these links to Wikipedia opens in separate window.) Taking nicotine and alcohol into the body over time reduces the levels of these as well as other 'happy chemicals'.JAS is thus the physical 'origin' or cause of joy. OJAS is the 'stuff' that the body's inner intelligence creates to make 'happy molecules' in our mind-body system.
Stress causes the release of a hormone called cortisol. Giving rats daily injections of corticosterone (rat cortisol) for several weeks kills certain brain cells. Stressing the rats each day for the same amount of time has an identical effect. Cortisol has been shown to damage and kill cells in the hippocampus (the brain area responsible for your episodic memory) and there is robust evidence that chronic stress causes premature brain aging.
