🌗 Seasonal Biology

How light, hormones, digestion, energy, and motivation shift across the year

Seasonal biology explains why the body feels different at different times of the year—even when routines, responsibilities, and environments stay the same. These shifts are not psychological quirks or motivational flaws. They are biological responses to changes in light exposure, temperature, and environmental signaling that directly affect hormones, metabolism, nervous system tone, and cognitive-emotional energy.

The body does not simply react to seasons—it anticipates them.
