Sun, a graduate of the MA Industrial Design programme at London's Central Saint Martins, developed the toolkit as a way to show that our emotional health is equally as important as our physical state.
"In spite of culture, background, wealth – everybody suffers the same emotional ups and downs of life," said the designer. "What if we treated emotional health equally to psychical health? This kit is designed for very different emotional scenarios."
Each of the five products developed by Sun are intended to provide a different comfort.
The Purple Breathing Mask emits calming scents when the user inhales, allowing them to think clearly in intense situations.
The Indigo Third Eyeglasses have three lenses to remind the user to use their "third eye" and look at things from a different perspective, while the Blue Stress Buster is a portable speaker that visualises sound with blue ink.
Should the user get involved in an argument, the Green Meditating Stethoscope helps them tune into their breath and meditate, and a Yellow Confidence Booster is a super-light padded jacket that helps people who "lack the confidence to solve dilemmas or address a situation".
Mental health is becoming an increasingly explored topic in the design industry, particularly among graduates.
At this year's Design Academy Eindhoven graduate show, designer Nicolette Bodewes presented a tactile toolkit designed to be used in psychotherapy sessions, while Yi-Fei Chen channelled her personal struggle with speaking her mind into a gun that fires her tears.
The Central Saint Martins graduate exhibition takes place until 25 June. Other projects on show include a virtual-reality sex-toy kit intended to help rehabilitate those with "extreme sexual fantasies", and a group of misbehaving robots designed purely to annoy you.
