When people feel happy, β-endorphin, dopamine, oxytocin and serotonin are secreted in their brains.
β-endorphin activates brains, strengthens immune systems, prevents from various diseases and enhances memories.
Dopamine makes people feel pleasures.
Oxytocin enhances memories.
Serotonin gives us mental stabilization.
Making a habit of exercising is the best way, to always be secreting these pleasure substances in our brains.

On the other hand, stress substances which are cortisol and noradrenaline are secreted in our brains when we have negative feelings like anger, jealousy, fear and anxiety.
Cortisol is a fundamental hormone for living bodies. However, if it is secreted too much, hippocampus which plays a central role in our memory circuits, atrophies.
Noradrenaline is a substance which causes living bodies to fight or escape from enemies. To let them get ready for battle, it raises blood pressure, supplies blood all over the body and increases blood glucose levels, so that muscles are used immediately.
Noradrenaline is also a fundamental substance. But if it is secreted too much, there is a possibility that it will increase the risks of high-blood pressure, diabetes and brain haemorrhage etc. because it has the effect of raising blood sugar.
