Infrared saunas have gained popularity for their wide range of health benefits, from muscle recovery to detoxification. One of the most impactful yet often overlooked benefits is their ability to significantly improve circulation. But how does this work, and what does the science say? Let’s take a deeper dive into how infrared sauna therapy can enhance blood flow and why it matters for your overall health.
How Infrared Heat Affects Circulation
Unlike traditional saunas, which heat the air around you, infrared saunas use infrared light waves to penetrate the skin and heat the body from within. This deep tissue warming triggers several physiological responses that promote better circulation:
-
Vasodilation (Widening of Blood Vessels)
-
When the body absorbs infrared heat, it naturally responds by expanding blood vessels (a process called vasodilation). This increases blood flow and allows oxygen-rich blood to reach tissues more efficiently.
-
A 2015 study published in the Journal of Complementary & Alternative Medicine found that infrared sauna use led to improved blood vessel function, which is beneficial for people with poor circulation and cardiovascular concerns.
-
-
Enhanced Nitric Oxide Production
-
Nitric oxide is a crucial molecule in the body that helps relax blood vessels and improve circulation. Studies suggest that infrared sauna therapy stimulates nitric oxide production, leading to lower blood pressure and better vascular function.
-
According to research from the American Journal of Cardiology, infrared therapy has been shown to improve endothelial function—the ability of blood vessels to expand and contract effectively.
-
-
Increased Heart Rate Similar to Exercise
-
During an infrared sauna session, the body’s core temperature rises, causing the heart rate to increase similarly to moderate exercise.
-
A study in JAMA Internal Medicine found that regular sauna use mimicked the cardiovascular benefits of physical activity, reducing the risk of hypertension and heart-related diseases.

Why Improved Circulation Matters
Better circulation means that oxygen, nutrients, and immune cells can travel more efficiently throughout the body. This leads to a variety of health benefits, including:
-
Faster Muscle Recovery: Increased blood flow helps deliver oxygen and nutrients to tired muscles, speeding up recovery and reducing soreness after workouts.
-
Pain Relief: Enhanced circulation can help reduce inflammation, making infrared saunas a great option for those suffering from chronic pain conditions like arthritis or fibromyalgia.
-
Better Skin Health: Improved blood flow delivers essential nutrients to skin cells, promoting a healthier, more radiant complexion.
-
Boosted Detoxification: While sweating alone is a great detoxifier, better circulation enhances the body's ability to flush out toxins through the lymphatic system and kidneys.
How to Use Infrared Saunas for Circulatory Benefits
To maximize the circulatory benefits of infrared sauna therapy, follow these guidelines:
-
Session Length: Aim for 15-30 minutes per session, depending on your tolerance.
-
Frequency: For noticeable cardiovascular benefits, 3-4 sessions per week are recommended.
-
Hydration: Drink plenty of water before and after each session to support circulation and prevent dehydration.
-
Temperature: A moderate temperature (45-60°C or 113-140°F) is ideal for gradually increasing circulation without overwhelming the body.
Final Thoughts
If you’re looking to enhance your circulation naturally, infrared sauna therapy offers a scientifically-backed, non-invasive solution. By promoting vasodilation, increasing nitric oxide production, and mimicking the cardiovascular effects of exercise, infrared saunas can be a powerful tool for heart health, muscle recovery, and overall well-being.
Regular use, combined with proper hydration and a healthy lifestyle, can provide long-term circulatory benefits, making it an excellent addition to any wellness routine.
