Tailored Benefits of Infrared Saunas for Athletics

When it comes to excelling on the field and reducing recovery times, athletes are always looking for the next big optimisation – as an approach to physical rehabilitation, it’s why infrared saunas have become central to recovery and athletic performance. Infrared light penetrates far deeper into muscle tissue than conventional forms of radiant light, leading to an incredible range of physiological benefits – backed by a healthy discourse of scientific research. The team at Sun Stream Saunas NZ champions these products, as tools for athletes to speed up recovery and improve overall athletic performance. This article talks about all how the benefits of infrared sauna can support athletes, from improved recovery of muscles to better cardiovascular health.

1. Facilitated Nutrient Delivery and Development of Heat Shock Proteins

When athletes engage in physical activities, their muscles strain, leading to microfibre tears and inflammation, a natural part of the muscle-building process. Infrared saunas emit wavelengths of light that penetrate deep into muscle tissues, delivering a deep, soothing warmth.

This heat increases blood flow to the muscles, which is necessary for carrying nutrients and oxygen that aid in repairing and eliminating metabolic waste such as lactic acid, reducing soreness and increasing recovery speed.

Infrared heat also increases the creation of heat shock proteins, which are essential for cell stress resistance and protein repair. These proteins assist muscle cells to recover from physical stress faster and more efficiently. As a result, athletes recover faster and experience less inflammation, allowing them to return to training sooner.

A study published in Biology of Sport examined the impact of a single infrared sauna session on post-exercise recovery. It revealed increased neuromuscular performance recovery and reduced muscle pain following resistance training.

2. Enhanced Circulation and Oxygenation

The cardiovascular system plays a pivotal role in recovery and performance. Infrared saunas mimic the cardiovascular stress of a light workout through a natural body response called thermoregulation—where the body works to cool itself, resulting in increased heart rate and circulation. This increased blood flow is particularly beneficial after workouts as it helps transport oxygen-rich blood to depleted muscles, facilitating faster recovery and reducing fatigue.

Furthermore, the sauna’s heat causes vasodilation, in which blood vessels enlarge, boosting overall blood flow and allowing more nutrients and oxygen to reach tissues throughout the body. This mechanism speeds up tissue healing and helps remove carbon dioxide and other waste materials.

A study in Evidence-Based Complementary and Alternative Medicine (2018) explains how such thermal therapies boost cardiovascular health, which is critical for sports performance and recuperation.

3. Greater Range of Motion

Infrared saunas help to increase flexibility and range of motion through the deep heat they emit, which affects collagen fibres in tendons and ligaments. Collagen, a key protein in connective tissues, becomes more pliable under sustained heat. This thermal effect reduces the viscosity of joint fluids, making joints more flexible and less prone to stiffness.

This helps after workouts when muscles and joints stiffen. Heat relieves muscle tension, improving flexibility. Warm muscles from infrared rays stretch more, reducing the risk of strains and sprains during exercise. Thus, infrared saunas assist athletes in maintaining and improving their flexibility and range of motion, which is essential for optimum performance and injury prevention.

4. Pain Relief and Stress Reduction

Infrared saunas provide pain relief by promoting the release of endorphins, the body’s natural painkillers. Heat dilates peripheral blood vessels, increasing blood flow, reducing discomfort, and speeding recovery. This speeds up muscle aches, joint pain, and stiffness relief for athletes. Infrared heat penetrates deep muscle tissues and sensitive joints, soothing them more than heating pads.

Sauna heat induces the autonomic nervous system to enter a parasympathetic state, when the body rests and digests, counteracting the stress-induced sympathetic state of ‘fight or flight.’ Stress, cortisol, mood, and well-being improve with this relaxation reaction. Regular sauna sessions can lead to a persistent state of relaxation and reduced anxiety, which is vital for mental health and optimal performance.

A clinical study in the International Journal of Hyperthermia 2021 found that thermal or sauna therapy significantly reduces visual analogue pain, pain behaviours, self-rating despair, and fury.

5. Cardiovascular Benefits

Sitting in an infrared sauna causes the heat to infiltrate your body and elevate your core temperature. This heat action increases your heart rate and dilates your blood vessels, a process known as vasodilation. These responses increase blood flow and improve cardiovascular function. Regular sessions can improve heart rate variability, reduce arterial stiffness, and increase cardiac output.

Furthermore, the heat from the sauna lowers blood pressure over time due to increased blood vessel elasticity. This is crucial for decreasing the burden on the heart and minimising long-term complications associated with high blood pressure.

Finnish Kuopio Ischemic Heart Disease Risk Factor Study discovered that frequent sauna bathing was related to lower chances of sudden cardiac death, coronary heart disease, and cardiovascular disease.


When infrared sauna sessions are incorporated into an athlete’s recovery routine, the result is a scientifically validated benefit for athletes in terms of both physical wellness and performance, with infrared heat penetrating beyond the surface of the skin to soothe aching muscles and hasten recovery, while improving cardiovascular health and neuromuscular recuperation benefits.

The evidence from various scientific studies emphasises that infrared saunas underpin a faster recovery and maintenance of optimum athletic performance. As athletes increasingly seek the most beneficial recovery strategies, it goes without saying that infrared saunas stand out as a compelling, research-backed solution that marries traditional heat therapy with contemporary technology.
