What are the effects of sunspots on humans?

Answer:
There are no direct effects of sunspots on people.

Indirectly, there are a variety of effects, mostly minor. High sunspot numbers correspond with increased probability of solar activity, which may result in increased solar wind or coronal mass ejection (CME) activity. High solar activity and CMEs can result in disruption of electromagnetic communications such as radio and TV, and very high CME activity can damage satellites. In one spectacularly intensive solar storm, the induced voltage in telegraph wires in the 1860's caused fires in telegraph offices.
