Under any circumstances, it is always best to laugh. Study reveals that smile, even insincere, "deceives" the brain to make us happier.

Happiness is a nap - Brief naps improve your sense of well-being
Surely you have heard someone tell you to smile.
Depending on the mood at the moment, this is not the best advice.
But there is a reason to smile.
And even forcing the contraction of the facial muscles.
Science has shown that mere act can lift the mood, reduce stress and improve the body's defenses.
And it can even make you live longer.
But if happiness makes us smile, does the opposite also happen?
In fact, smiling triggers chemical reactions in the brain by releasing hormones like dopamine and serotonin.
Low levels of these hormones are associated with depression.
In other words, smiling can trick the brain into believing you are happy.
Which may eventually come true.
And it doesn't end there.
Depressive states weaken the immune system.
But as we smile, the brain "sees" the muscle activity in the face and understands that happiness has come.
In fact, a study of people who applied botox found that because they can't frown, they are happier.
The research was done by the University of Cardiff (Wales).
