microcurrent stimulation helps maintain immune cell activity across the day-night cycle

Microcurrent stimulation prevented the time-dependent (circadian) decline in macrophage phagocytosis during the dark period when applied during the light period (ZT2), maintaining elevated phagocytic activity across the circadian cycle.

What this means for you

Your immune system naturally dips in activity at certain times of day — that's just biology. This finding suggests microcurrent stimulation may help keep your immune cells more consistently active throughout the day, which could mean more reliable immune readiness rather than peaks and valleys tied to your body clock.
