The first s.a.d. t-shirt (01) has a sun and cloud design where the sun has been overprinted with black heat sensitive ink. The ink turns transparent at 32 degree centigrade which happens when the wearer is outdoors in sunshine. The other t-shirt (02) has a cloud motif. The words "The sun is nature’s prozac" was screen-printed with yellow heat sensitive ink.
The t-shirt was designed by Keith Hancox who knows someone who has seasonal affective disorder which is also known as winter depression. The seasonal mood variation is linked to the lack of light during the cold months.
