The body language expert added that the expression of sadness serves a purpose and is a non-verbal signalling system “that lets those around us know that we’re not okay”.

“Reaching out and providing comfort or seeking solace and reassurance in others during times of intense grief or sadness is a very human reaction,” she pointed out.

During the service, and in a moment of quiet reflection, Prince Harry and Meghan were seen with “their heads tilted, shoulders slumped forwards, their eyes and head downcast, mouths slightly downturned, both using self-protective gestures”.

“Harry’s hand resting on his torso, Meghan’s hands clasped in front forming a non-verbal protective barrier, suggesting sadness, a level of discomfort and a need for reassurance,” the expert suggested.
