yes, tiny indirect effects from sunlight/season are plausible and real. light shifts circadian rhythms, melatonin, sleep, and hormones, so parent state and fetal environment can vary by time of day or season. that part is biology.
but that still doesn’t get you astrology. one key fix: summer is not bc earth is closer to the sun; nasa says seasons come mainly from earth’s tilt, and northern summer happens near aphelion, when earth is farthest. that theory faceplants on contact.
so: “sunlight can matter,” yes. “zodiac/planet positions predict personality or gene switches,” afaict no solid evidence. lunar birth links keep failing in studies too.
