I’m writing this with a heavy heart. Last week, I lost a neighbor to suicide, and it’s reminded me how critical it is that we talk about depression, especially now, as winter sets in.
Suicide rates increase during the holidays and winter months. While many assume it’s purely emotional, loneliness, holiday stress, and seasonal sadness, there is often a biological component that goes unrecognized.
The Winter Factor
Shorter days mean less sunlight, which affects our body’s production of serotonin and vitamin D, both crucial for mood regulation. For those at higher altitudes or in northern climates, this effect intensifies. Add in the cold, keeping people indoors and isolated, and you have a perfect storm for biochemical depression.
For some people, genetic variants make them especially vulnerable to these seasonal shifts. Their bodies may struggle to produce enough mood-regulating neurotransmitters or process the nutrients needed for balanced brain chemistry.
This isn’t a weakness. It’s biochemistry.
Looking Out for Each Other
Depression often hides behind “I’m fine.” Please check on people who seem withdrawn, those who have struggled before, or anyone going through major life changes. Sometimes just showing up, bringing coffee, sending a text, sitting together in silence, makes all the difference.
There Is Help
If you’re struggling with depression, please know that understanding the genetic and biochemical factors can be life-changing. It removes shame, points toward effective support, and offers real hope.
