The Science Behind: Broken Heart Season

Weather affects mood through your brain chemistry. Here's how.


The light-serotonin connection:

Sunlight triggers serotonin production in the brain. Serotonin is often called the "happiness chemical"—it regulates mood, sleep, appetite.

Less light = less serotonin = lower mood.

This isn't metaphor. It's neuroscience.


The melatonin factor:

Darkness (or gray skies) increases melatonin, the sleep hormone. Too much melatonin = daytime drowsiness, lethargy, desire to hibernate.

Rainy season's constant low light keeps melatonin higher than it should be during the day.


Evidence-based helps:

Light therapy: Bright light boxes (10,000 lux) for 20-30 minutes in morning can help

Vitamin D: Supplementation may help if levels are low from reduced sunlight

Exercise: Physical movement boosts serotonin even without light

Morning light exposure: Get outside when you can, even if cloudy


Your rainy season sadness isn't weakness. It's chemistry responding to environment. You can work with it.
