As a lifelong Canadian, I’m no stranger to that familiar sinking feeling in my chest as the days get shorter, dimmer and colder. I suffer from seasonal affective disorder (Sad), which also affects about one in 20 people in the US.
“Sad is a type of depression that happens at certain times of the year, usually in the fall and winter when there’s less sunlight,” said Dr Stefanie Mazer, a licensed psychologist and founder of the psychology practice Mindwise, Inc. Changes in sunlight can affect your body’s internal clock and levels of serotonin and melatonin, which influence mood and sleep, Mazer explained. People with Sad often feel low energy, sadness and irritability, with noticeable changes in sleeping or eating.
