Why it matters
The mood and energy difference between summer and winter is partly explained by light — more daylight means more morning light exposure, better circadian rhythm regulation, more vitamin D synthesis, and more time outdoors moving. But how much the seasonal change affects you specifically is individual. Some people experience significant seasonal depression and fatigue. Others barely notice. If your winter is consistently much harder than your summer, the light and movement change is almost certainly the mechanism — but Normal helps you confirm which specific factors are driving it for your body.
When Normal helps
Normal tracks your mood and energy across seasons and finds the specific environmental and lifestyle factors that are driving your seasonal differences. It helps you identify which interventions — light therapy, movement, vitamin D, social time outdoors — make the most difference for your body.
How Normal finds it
Tell Normal how you're feeling every day across seasons. Over several months it builds a picture of your seasonal pattern and the specific factors most associated with your seasonal wellbeing changes.
