Cold water swimming can induce positive stress

The tradition of cold water swimming (or taking a cold plunge, or even a cold shower) has been shown to release the same hormones triggered during a stress response. This can have the effect of increasing blood flow, improved mental acuity, and more.

Reduced inflammation from cold plunges lacks scientific support

The cold water triggers immediate cold shock, increasing heart rate and blood pressure, and prolonged exposure can lead to cold-water incapacitation and hypothermia. Plungers are encouraged to enter the water slowly and manage their breathing to reduce the risk of shock. Warm baths post-plunge are discouraged, and exercise is generally better for recovery.

Can microdosing improve mental health?

Animal studies involving microdoses of psilocybin, the psychoactive component in magic mushrooms and ketamine, found it helped to alleviate anxiety and inflammation, an immune response that can cause damage when chronically active. Human studies are ongoing. In at least one double-blind study, where researchers and patients don't know who got a placebo versus the real thing, about half of the participants incorrectly guessed they had been given placebos.

Hippocratic doctors treated severe mental illness with the poisonous plant hellebore

Since symptoms like hallucinations were believed be due to an imbalance of black bile, yellow bile, blood, and phlegm, the treatment at the time was to bring those humors back into balance. That meant standard treatments could include bleeding a patient or using substances like hellebore to induce vomiting or diarrhea.

Some claim breathwork can improve mental health, help process trauma, and more

Research shows people who practice breathing exercises see a decrease in depression and stress levels, and that such exercises are about as effective at treating PTSD as conventional approaches. Even something as simple as extending exhales can slow one's heart rate and activate the parasympathetic nervous system.

The strange endurance of consuming blood for health

Blood's importance to humanity is best summarized this way: without it, we die.

Myokines are molecules that facilitate some of the benefits of exercise

When muscles contract, they release ‘hope molecules’ (myokines) such as IL-6 and irisin. These proteins then travel through the bloodstream to reduce inflammation, improve insulin sensitivity, and even support brain repair. This piece illustrates how movement triggers a systemic healing cascade throughout the human body.

Some data shows cold showers can help with depression

An icy water exposure can lead to the release of norepinephrine, cortisol, dopamine, and other stress hormones that are beneficial, among other potential effects.

Some athletes warm up with equipment from other sports

Baseball superstar Shohei Ohtani uses a cricket bat; his teammate Yoshinobu Yamamoto throws a javelin. Quarterback CJ Stroud shoots free throws. The reasons are partially physical (it's good to exercise different parts of your body) and partially mental (it's nice to take the pressure off with someone else's game).

Medical recognition of strokes stretches back to ancient Greece

Every minute, 750 milliliters of blood flows to the brain, supplying 20% of the body’s oxygen. A sudden disruption—whether from a clot (ischemic stroke) or a bleed (hemorrhagic stroke)—can be life-threatening. From ancient Greek theories to modern CT and MRI scans, here’s how stroke science has evolved over time.

Why CAR-T therapy has become one of the main focus areas for autoimmune diseases

The therapy, originally targeting cancer, involves taking a patient's own T cells, genetically reprogramming them to recognize and attack a specific target and then infusing them back into patients. For autoimmune diseases, the therapy instead programs them to target immune cells that are causing problems, restoring immune system tolerance.

CAR-T is showing promise for treating lupus—previously thought to be incurable

A small number of lupus patients have remained in complete remission for years after undergoing an experimental CAR-T cell therapy that seems to eliminate enough B cells to fuel a "deep reset" of the immune system. CAR-T therapy is also being used experimentally to treat MS, myositis, and other autoimmune disorders. (Some users may experience a paywall.)

Peptide TB-500, promoted for regenerative healing, is not FDA approved

Watch a board-certified sports medicine therapist detail his thinking about this synthetic peptide; he says it's "promising but unproven." He notes that this product is designed to mimic the natural protein thymosin beta-4, found in human and animal tissues, which promotes wound healing. TB-500 is classified as a research peptide for recovery, meaning it's not approved for human use and has not yet undergone rigorous human trials on its safety and efficacy.
