Smile for your Wellbeing

Smiling has a myriad of benefits, and the smile doesn't even have to be real. Egao is a mobile app that helps you reap those benefits to live a healthier and happier life.

Benefits of smiling

To name a few: smiling, e.g., elevates mood, relieves stress, boosts the immune system, and reduces pain.

Elevate mood

We smile when we are happy. But did you know that we also become happy when we smile? Even fake smiling activates pathways in your brain that put you in an emotionally happy state [1]. This phenomenon is known as the facial feedback effect. A 2019 meta-analysis [2]of 138 studies verified its moderate but significant impact on happiness.

Relieve stress

If there is one thing there is too much of in today’s world - it is stress. Stress influences how we feel, look, and interact with others (mostly not for the better). Taking a short break and putting on a smile helps you decrease stress levels [3]. You and your surrounding will benefit from it.

Boost immune system

Smiling can also strengthen your immune system. Immune functions seem to improve because it relaxes you due to the release of neurotransmitters [4]. A simple smile can contribute to your overall health.

Reduce pain

Smiling releases endorphins, which are our body’s natural painkillers. When smiling, we are better prepared to deal with pain than otherwise [5].
