Smiles are Cheaper than Therapy

They say “ a smile is happiness you find right under your nose”. Let’s explore the fascinating connection between smiling and your overall health. Beyond the aesthetic benefits, a smile can have a profound impact on various aspects of your physical and mental well-being. At Renew Dental Lounge, we love to smile and help you renew your smile, so let’s delve into the science behind the power of smiles.

The Science of Smiling:

  • Release of Endorphins: We flex our face muscles as we smile and this triggers our body to release endorphins. Endorphins can be described as happy hormones. Endorphins can make us feel happy and warm inside. Your body releases endorphins and dopamine when you smile. These neurotransmitters are  happy hormones that can elevate your mood, reduce stress and relax your body.  In other words, smiling can trick your body into believing you are happy which can then spur actual feelings of happiness.
  • Stress Reduction: Smiling increases the release of serotonin which is associated with reduced stress and depression by lowering cortisol and adrenaline.

Smiles and Heart Health:

  • Lower Blood Pressure: Stress can cause an increase in heart rate and raise blood pressure. Smiling can lower blood pressure by increasing mood-enhancing hormones, (endorphins, dopamine & serotonin) whilst decreasing stress-enhancing hormones (adrenaline & cortisol).
  • Heart-Healthy Habits: A positive outlook, often reflected through a smile, can encourage heart-healthy habits. Studies have shown that smiling after a stressful event help the heart rate lower more quickly.

The Immune System Boost:

  • Smiling and Immunity: Studies suggest there is a link between regular smiling and a strengthened immune system, enhancing your body’s ability to fight off illnesses. The release of serotonin helps reduce stress and through this, it is thought to boost your immune system.

Pain Management through Smiles:

  • Natural Painkillers: Smiling may act as a natural painkiller, potentially reducing the perception of pain in various situations and it all down to those endorphins, those happy hormones,  and serotonin released when we smile.

Smiles and Longevity:

  • Longevity Studies:  Studies have shown that a positive outlook, or optimism, which is linked to smiling, is associated with a lower risk of early death from cancer and infection.

The Social Impact of Smiles:

  • Social Connections: When we see someone smiling, it can put us at ease and often leads to increased liking and trusting of that person. Smiles are universally recognised as expressions of joy and happiness.
  • Smiles and Empathy: Smiling is contagious, how often have you heard that a smile has the power to light up a room? A beautiful sentiment but there is truth in it. Your brain automatically notices and interprets other people’s facial expressions and sometimes you may mirror them.

Oral Health and Smiling:

  • Oral-Systemic Link: This is the connection between the health of the mouth and the overall health of the body. Studies have shown that gum disease may be associated with cardiac disease, diabetes, strokes and even dementia. So maintaining good oral health, including regular dental check-ups, can positively influence overall well-being.

Smiling for Mental Health:

  • Smiles and Mental Resilience: Smiling boosts your mood by releasing those feel good hormones, endorphins, serotonin and dopamine. This encourages an emotionally positive state, particularly in the face of stress and challenges.
  • Depression and Smiles: A simple smile can trigger the release of neuropeptides that improve your neural communication. It also causes the release of dopamine and serotonin, which can boost your mood. Think of smiling as a natural antidepressant.

So, let’s spread those smiles and enjoy the positive ripple effect they create!
