Why Most Cats Sleep on Their Left Side—and What It Means for Your Fertility Journey

Ever noticed how your cat curls up on their left side every time they nap? You might have thought it’s just a quirky animal habit, but recent scientific research reveals there’s a fascinating reason behind this feline behavior—and it might just have surprising implications for your own fertility and wellbeing.

A recent article on Gizmodo titled “Most Cats Sleep on Their Left Side, and Scientists Think They Know Why” highlights how cats tend to favor their left side during sleep. Scientists suggest this position keeps the right hemisphere of their brain alert to detect immediate threats. This discovery isn’t just a fun fact; it opens a window into understanding how sleep positions affect brain function and stress levels—two critical factors in human fertility.

So, why should you care about your sleep position when trying to conceive?

Sleep quality plays a huge role in reproductive health. Poor sleep or suboptimal sleeping postures can elevate stress hormones like cortisol, disrupting the delicate hormonal balance needed for ovulation and embryo implantation. Just as cats intuitively shift to protect themselves and stay alert, humans might unconsciously favor certain positions that impact relaxation and blood flow.

The Link Between Sleep Position and Fertility

While the cat’s left-side sleeping habit is tied to brain hemisphere alertness, in humans, sleeping on the left side can benefit circulation, including improving blood flow to the uterus and kidneys. Increased uterine blood flow can enhance oxygen and nutrient delivery critical for sustaining a healthy pregnancy.

Medical studies have shown that pregnant women who sleep on their left side have better outcomes regarding fetal growth and reduced risk of stillbirth. It’s reasonable to extend this advice to those on their fertility journey, aiming to optimize every physical factor that can aid conception.
