Your stomach has a pulse — a slow electrical wave every ~20 seconds, even when it's empty.

In a 2025 Nature Mental Health study, researchers at Aarhus University recorded that stomach rhythm (electrogastrography) while scanning the brains of 243 adults. The surprise: people whose brain activity was most tightly synced to their stomach — especially in attention and control networks — reported more anxiety, depression, stress and fatigue, and lower well-being.

It's correlational, in a young non-clinical sample, and no treatment has been tested yet. But it points to something many people feel: anxiety that lives in the gut may reflect a brain that's listening too hard. Swipe for the mechanism, the honest limits, a 7-step protocol and a self-check (with red flags that need prompt care).

If stress hits your stomach first, book your functional neurology evaluation online at drleiladoolittle.com to find out what's really driving your stress-stomach loop — from vagal and nervous-system patterns to gut, hormone and nutrient drivers — and get a personalized plan to help your gut and brain stop sounding the alarm.

Five hundred years ago, an artist dissecting hearts sketched swirling spirals of blood just behind the aortic valve. Modern imaging has since confirmed those vortices are real.

The spiral is written into the heart from the very beginning. In the embryo, the heart starts as a simple straight tube, then bends and loops on itself within weeks, folding into the chambers it will keep for life.

A few more things worth knowing:

Heart disease is the leading cause of death in women, and warning signs often look different: unusual fatigue, shortness of breath, nausea, or pain in the jaw, back, or arm.

How fast your heart rate falls in the first minute after exercise is a window into autonomic health. A slow recovery can flag risk long before a standard checkup does.

Your heart muscle cells renew very slowly across a lifetime, which is why protecting them early matters so much.

In my practice, heart health means more than a lab number. It means rhythm, flexibility, flow, and a nervous system that lets the heart do its work.

How quickly does your heart settle after a hard climb?

The placebo effect isn't "all in your head." It's a circuit in your head — and scientists just traced it.

In a 2024 Nature study, researchers at UNC, Stanford and the Allen Institute found that when mice expected pain relief, neurons in the rostral anterior cingulate cortex fired more strongly into the pontine nucleus, a brainstem relay to the cerebellum never before linked to pain. Most of those pontine neurons carry opioid receptors. Blocking the pathway erased placebo relief; switching it on relieved pain with no placebo at all.

Humans show the same principle. In a JAMA Psychiatry trial of 151 adults with chronic back pain, 66% were pain-free or nearly pain-free after pain reprocessing therapy, vs 20% with placebo and 10% with usual care. Swipe for the circuit, the honest limits, a 7-step protocol and a self-check (including red flags that need prompt care).

If you live with chronic pain, book your functional neurology evaluation online at drleiladoolittle.com to find out what's really driving it — from nerve, inflammatory and hormonal drivers to sleep and a sensitized nervous system — and get a personalized plan to help your brain turn the volume back down.

Your brain didn't break during pregnancy. It rebuilt itself. 🧠

In 2024, scientists scanned one first-time mother 26 times, from before conception to 2 years after birth. Gray matter thinned across about 80% of the cortex in step with her rising estrogen and progesterone. In 2025, a study of 127 first-time mothers found the same U-shaped pattern: about 4.9% less gray matter by delivery, partly recovered by 6 months. Women who were never pregnant and partners raising the baby showed no such change.

The changes cluster in the networks we use to read other people's needs. "Mom brain" may be the brain specializing, not failing. Swipe for the mechanism, the honest limits, a postpartum brain-support protocol, and the signs that mean it's more than mom brain.

If your postpartum fog, low mood or exhaustion isn't lifting, book your functional neurology evaluation online at drleiladoolittle.com. We'll find out what's driving it, from iron, thyroid and hormone shifts to sleep and nutrient depletion, and build a personalized plan to support your brain's rebuild.

Your hair keeps a diary.

Every strand records what moved through your bloodstream while it grew, which is why hair can be analyzed for certain minerals and metals. At roughly one centimeter a month, the hair at your shoulders reflects your physiology from about a year ago.

A few more things worth knowing before you mix your first blend:

Losing 50 to 100 hairs a day is normal. A sudden jump is a message, and it usually points to something that happened two to three months earlier.

Give any scalp oil at least three months before you judge it. That is about how long a resting follicle needs to return to visible growth.

Peppermint feels cool because menthol activates TRPM8, the same cold receptor that senses winter air. The tingle is a nerve signal, and the flush that follows is blood flow.

Hair is almost entirely keratin, a protein. If breakfast is coffee and a bar, your follicles are working with very little to build from.

Water is the most familiar substance on earth, and one of the strangest.

It is one of very few substances that expands when it freezes, which is why lakes freeze from the top down, protecting the life beneath.

A few more fascinating facts about water and flow:

Your capillaries do not stay open all the time. Tiny muscle rings at their entrances open and close in rhythmic waves, a pattern called vasomotion, directing blood where it is needed most.

Movement recruits capillaries. During exercise, many more open in working muscle, which is part of why a walk can clear a foggy mind.

Cold hands are not always about the weather. They can reflect how your autonomic nervous system is directing blood flow.

A newborn is about 75 percent water by weight. By adulthood, it is closer to 60 percent, and your brain and heart are among the most water rich organs you have.

Some of the ideas in this reel are established, and some, like structured water, are still debated. I share them as an invitation to curiosity, not as settled fact.

Are your hands and feet usually warm or cold?

When people sing together, their heart rates begin to rise and fall together too.

In one study of choir singers, slow, structured singing guided the breath, and with it, the heart rhythms of the singers came into sync. Coherence is not only something that happens inside one body. It can happen between people.

A few more things about your heart and brain:

Heart rate variability naturally declines with age, but it is trainable. Slow breathing, movement, sleep, and connection can all raise it.

Humming and slow exhaling stimulate the vagus nerve, which is one reason a long sigh feels so good.

Your heart rhythm often shifts before you consciously notice an emotion. The body frequently knows first.

Morning HRV is one of the most honest measures you can track at home. A dip after a late night or a hard week is your nervous system asking for recovery.

This is why HRV is part of how I evaluate the nervous system. It gives us a living window into regulation, and a way to watch it improve.

Five hundred years ago, Leonardo da Vinci sketched swirling vortices of blood inside the root of the aorta, just behind the heart valve. He believed those spirals helped the valve close. Leila Doolittle

In 2014, researchers using modern MRI confirmed that those vortices are real.

The spiral seems written into the heart from the very beginning. In the embryo, the heart starts as a simple straight tube. Within weeks it bends and loops on itself, folding into the chambers it will keep for a lifetime. Embryologists call it cardiac looping.

Over an average life, that spiral muscle will beat roughly two and a half billion times, without rest.

Some of the ideas in this reel are well established, like ventricular torsion and vortex flow. Others, like the idea that the heart is more than a pump, are perspectives still being studied and debated. I find the questions they raise profoundly beautiful: what if the heart is not only a machine, but a living rhythm?

In my practice, heart health means more than numbers. It means rhythm, flexibility, flow, and a nervous system that lets the heart do its work.

Painful s*x isn't normal, even if it's common. It often stems from root causes like hormonal shifts leading to vulvar and vaginal atrophy, thinning tissues, and pH changes. This can cause discomfort, tears, and infections. Our body's natural flora, predominantly Lactobacillus species, is crucial for health. A comprehensive approach is key to regeneration and healing.
