"Ruled by Mars, planet of action, Aries always have an abundance of energy and love to go, go, go," Kyle Thomas, Resident Astrologer at Love by Luna, tells POPSUGAR. "This leads many Aries to have difficulty sleeping because they're always ready for their next conquest." Restless sleeping patterns can happen often for this fiery sign if they don't channel their energy productively, rather than letting it fester within and keep them up at night.
