CARDIO BENEFITS: UC Research Shows Wearing Tefillin…is Good for the Heart

Research from the University of Cincinnati shows people who wear tefillin may receive cardiovascular health benefits, UC News reports.

The study suggests those benefits are the result of ischemic or reduced blood flow preconditioning which produces protection from the damage caused by heart attacks.

The research was published in the journal PLOS ONE and expands on similar research by Rubinstein from 2018.

“Tefillin is used for morning prayers for Jewish men over the age of 13 on an almost daily basis,” says Jack Rubinstein, MD, of the Division of Cardiovascular Health in the UC College of Medicine. “It is placed on the nondominant arm around the bicep and the forearm in a fairly tight manner. It is never worn in a fashion as to occlude the blood flow. This is traditionally worn for about 30 minutes continuously during prayers which involve sitting and standing resulting in occasional retightening of the strap around your arm.”

Rubinstein says the binding of the arm and the discomfort users often report may serve as a form of preconditioning and offer a substantial degree of protection against the damage that occurs when someone suffers a sudden loss of blood flow (acute ischemia) or after the blood supply is restored to a tissue or organ after an ischemic event (reperfusion). Such injuries occur during a heart attack when a section of the heart is deprived of oxygen and then damaged further when blood flow is reestablished.

Rubinstein says the researchers measured baseline information on all participants for 10 minutes in the morning, and then another round of data was obtained during and after 30 minutes of wearing the tefillin. The 30 participants, all healthy individuals between the ages of 18 to 40, had their heart rate measured before, during and after the wearing of tefillin.

“What we found is that wearing tefillin in both male and females caused changes to the heart rate associated with lowering of the metabolism as measured via heart rate variability,” says Rubinstein who explains that heart rate variability is how much variability there is between one heartbeat and the next heartbeat. “We can measure all kinds of different things from heart rate variability including probably the most important which is parasympathetic tone. Does it relax you and does it cause your metabolism [to] come down?”

Rubinstein says this study shows there is a measurable effect during and after wearing tefillin.

“It means that if we can have people wearing tefillin or a similar device, and they can get themselves to be preconditioned every day, we expect that those people should be protected or should have a decreased amount of damage if they should get a heart attack during the time they are protected,” he explains. “This is a low-intensity way of protecting people from heart attacks.”
