Infrared Sauna:

Blood Flow
Far-infrared heat increases blood flow and reduces muscle and joint pain

Heating of one area of the body produces reflex-modulated vasodilatations in distant-body
areas, even in the absence of a change in core body temperature’ i.e. heat one extremity and
the contra lateral extremity also dilates; heat a forearm and both lower extremities dilate; heat
the front of the trunk and the hand dilates. Heating of muscles produces an increased blood
flow level similar to that seen during exercise.

Infrared heat assists in resolution of inflammatory infiltrates, edema and exudates: The
increased peripheral circulation provides the transport needed to help evacuate the edema
which can help end inflammation, decrease pain and help speed healing.

Purpose of Study
To determine whether Infrared Sauna therapy improves blood vessel function (endothelial) in
patients with risk factors such as high cholesterol, high blood pressure, diabetes and smoking.
This dysfunction represents an early stage of arteriosclerosis (hardening of the arteries).

How did they do it?
Studied 25 men with at least 1 risk factor. Patients were treated in an Infrared Sauna for 15
minutes once a day for 2 weeks.

Results: Infrared Sauna Treatment

  • Significantly lowered blood pressure
  • Significant weight loss
  • Significantly lowered blood sugar
  • Significantly increased blood flow
  • Lowered cholesterol
  • Lowered triglycerides

Repeated Infrared Sauna treatment improves impaired blood vessel functions in patients with
high blood pressure, diabetes, smoking and high cholesterol. This suggests a preventive role
for sauna use for arteriosclerosis.
