One side

“you want to make sure that you don't have any stimulants in the system right before you do the blood pressure so you want to avoid any nicotine caffeine or alcohol within a few hours of doing a blood pressure”

Worth discussing with your GP, especially if you take medication or are pregnant. Entrain describes what is publicly taught; it does not prescribe.

Red and infrared light

Red and infrared light support mitochondrial function and skin resilience.

Strong consensus

“the red spectrum of light penetrates into the mitochondria kicks nitric oxide off and then the electrons can flow through”

Infrared light therapy

Infrared light therapy is widely valued for supporting mitochondria and relaxation.

Strong consensus

“infrared light which can penetrate 8cm into the body can help to clear this out of the way so that your mitochondria can carry on making ATP and water”

Infrared exposure

Infrared exposure helps support healthy blood flow and cellular energy production.

Strong consensus

“The main things are sunlight exposure, infrared light, anything that's going to build charge in your body is going to help build the structured water and that’s going to prevent this clotting response.”
