Some surprising facts about smiling
Fact 1
Newborn babies can smile as a reflex, but it isn’t until they reach six to eight weeks that they do learn to smile in a social way.
Fact 2
There are 19 different types of smile – but only six are for when we’re happy. The rest happen when we are in pain, embarrassed, uncomfortable or even miserable but want to portray something different.
Fact 3
Smiling can boost your immune system as it helps us to relax. This can release certain neurotransmitters which can help our immune system function better.
Fact 4
Smiling can also help us to destress. Studies show that this is because it can help our heart rate return to normal more quickly than when we have a neutral expression.
