Infrared saunas heat the body using infrared radiation at lower air temperatures than traditional saunas. The resulting rise in core temperature produces several measurable physiological responses. The following points reflect what research currently supports.
1. Raises Heart Rate and Improves Circulation
Infrared heat causes blood vessels to dilate and heart rate to increase, similar to the cardiovascular response of light-to-moderate exercise. This improves blood flow throughout the body during and shortly after a session.
2. Provides a Mild Cardiovascular Stimulus
The increase in heart rate and vascular dilation gives the cardiovascular system a gentle workout. Large observational studies of frequent traditional sauna use have linked higher session frequency with lower rates of cardiovascular events; far-infrared “Waon” therapy trials have also shown short-term improvements in symptoms and function in people with heart failure. These findings do not automatically apply to all commercial infrared saunas or healthy users.
3. May Temporarily Reduce Muscle Soreness and Joint Stiffness
Heat increases blood flow to muscles and connective tissue, which can ease feelings of soreness and stiffness after exercise or with everyday joint discomfort. Small studies, including some using far-infrared protocols, have reported reduced pain and improved comfort in conditions such as fibromyalgia and certain forms of arthritis.
4. Supports Relaxation and May Improve Sleep for Some People
The combination of heat and a quiet environment promotes a relaxation response. Many users report lower perceived stress and easier sleep after sessions, consistent with shifts toward greater parasympathetic activity. High-quality trials measuring objective sleep or cortisol changes remain limited.
5. Creates a Temporary “Glow” Through Increased Blood Flow
Greater circulation brings more blood closer to the skin surface, producing a short-term flushed appearance. Sweating can also help clear surface debris from pores. These effects are temporary and do not constitute proven long-term skin rejuvenation.
6. Offers a Passive Form of Heat Therapy That Complements Active Recovery
Because the body responds to the heat stress with increased circulation and mild cardiovascular demand, infrared sauna sessions are sometimes used after workouts. This is best viewed as a supportive recovery practice rather than a replacement for active recovery methods or proper training.
7. Produces Measurable Physiological Changes Without High Air Temperatures
Infrared units typically operate at lower ambient temperatures than traditional saunas while still elevating core body temperature enough to trigger sweating, heart-rate increases, and vasodilation. This makes the experience more tolerable for some people while delivering the same core heat-related responses.
Notes on use
Start with shorter sessions, stay hydrated, and stop if you feel lightheaded or overheated. People with cardiovascular conditions, pregnancy, or heat intolerance should consult a clinician before regular use. Effects vary by individual, session length, temperature, and frequency; most research is short-term or observational.
What to Expect From an Infrared Sauna Session in Watkinsville
An infrared sauna session at Thrive takes place in a private suite at our Watkinsville office. Our team explains how the session works, answers your questions, and reviews preparation and aftercare with you.
Before your visit, drink water and tell our team about any health concerns or medications you would like to discuss. During the session, you can relax while the sauna warms. If you feel lightheaded, uncomfortable, or overheated, end the session and let a team member know.
Session length and scheduling can be discussed when you book. Contact our Watkinsville office for current availability and pricing.
