A smile is an expression of happiness, delight, sociability, joy or amusement. Smiles are powerful. Smiling more often, regardless of your mood, can improve your health and even help you live longer.
Smiling is good for health
It alleviates stress
People who smile after a stressful task even if it isn’t an authentic smile have a lower heart rate than those who keep a neutral facial expression. Next time you start to feel your heart rate rise as a result of stress, focus on putting a smile on your face.
It lowers blood pressure
The act of smiling can lead to an immediate increase in heart rate and oxygen consumption, followed by a period of muscle relaxation, decreased heart rate and lower blood pressure.
It boosts the Immune System
It is a natural pain reliever
When you smile the neurons tell your body you are happy and your body releases dopamine, endorphins and serotonin, these neurotransmitters make you feel great.
Endorphins are a natural pain reliever with no side effects.
Try this test: Smile. Smiling can influence your feelings of positivity. Regardless of whether or not your smile is genuine, it still sends the message that "Life is good!" to your brain and, ultimately, the rest of your body.
