Introduction
Stepping into a heated yoga studio for the first time is an experience that stays with you. The heavy, humid air and the immediate beads of sweat on your skin signal a practice that is as much about mental endurance as it is about physical movement. While many practitioners are familiar with the intense 90-minute sessions or the vigorous "hot power flow" classes found in cities across the US, the story of where did hot yoga originate is a journey through different continents and eras.
At Hugger Mugger, we have seen yoga trends evolve since we began making props and mats in 1986, yet the popularity of heated practice remains a constant force in the community. Learn more about Hugger Mugger’s yoga heritage as we explore the roots of this steamy discipline, from the humid streets of India to the first heated rooms in Japan and the eventual boom in 1970s California. We will examine the key figures who shaped the practice and how the original method differs from the diverse hot yoga styles we see today.
Quick Answer: Modern hot yoga originated in the early 1970s when Bikram Choudhury moved to the United States. While the 26-posture sequence was developed in Kolkata, India, the practice of heating the room began in Japan to replicate India's tropical climate before being popularized in Los Angeles.
The Roots in Kolkata: Bishnu Charan Ghosh
To understand the origin of hot yoga, we must look further back than the 1970s. The technical foundation of the practice began in the 1920s in Kolkata, India. The central figure in this lineage was Bishnu Charan Ghosh, the younger brother of Paramahansa Yogananda (author of Autobiography of a Yogi).
Ghosh was not a traditional ascetic; he was a physical culturist who believed that yoga could be used as a scientific method for healing and strengthening the physical body. He founded the Ghosh College of Physical Education in Kolkata, where he blended traditional Hatha yoga asanas (postures) with modern physical therapy and weightlifting principles.
Bishnu Ghosh developed specific sequences designed to target internal organs, boost circulation, and rehabilitate injuries. One of his most dedicated students was a young man named Bikram Choudhury. It was under Ghosh’s tutelage that the specific postures used in modern hot yoga were refined. This lineage emphasized "physical culture," focusing on the body’s capacity for transformation through disciplined, repetitive movement.
The Influence of Hatha Yoga
While Ghosh brought a modern fitness perspective, the postures themselves were rooted in classical Hatha yoga. This traditional branch of yoga focuses on balancing opposing forces—the sun (ha) and the moon (tha). In the context of hot yoga, this balance is found in the relationship between exertion and relaxation. Each demanding posture is typically followed by a brief period of stillness, allowing the heart rate to settle and the practitioner to observe the effects of the heat on the body.
The Accidental Invention of the Heated Room
A common misconception is that yoga has always been practiced in rooms heated to 105 degrees Fahrenheit. In reality, the "hot" part of hot yoga was born out of necessity rather than ancient scripture. In India, the natural climate provides the warmth and humidity that makes muscles pliable and encourages sweating. However, as teachers began traveling outside of the tropics, they encountered a problem: cold environments made the body stiff and prone to injury.
In the late 1960s, before moving to the United States, Bikram Choudhury spent time teaching in Japan. During the cold Japanese winters, he noticed that his students’ muscles were too tight to safely perform the deep backbends and stretches inherent in the Ghosh lineage. Legend suggests that he was inspired by the saunas his students visited during their lunch breaks.
He began experimenting with space heaters in his yoga rooms to replicate the 80-to-90-degree climate of his hometown, Kolkata. He observed that the artificial heat not only protected his students from injury but also increased their focus and perceived intensity of the workout. This marked the shift from practicing yoga in a warm climate to intentionally creating a high-heat environment for therapeutic benefit.

The 1970s: The Los Angeles Boom
The formal birth of "Bikram Yoga" as a global brand occurred in 1971 when Choudhury moved to Los Angeles. He opened the Bikram’s Yoga College of India in Beverly Hills, and the timing was impeccable. The 1970s in California was a decade of intense interest in Eastern philosophy, fitness, and alternative wellness.
The practice quickly gained a following among celebrities and athletes. Its rigid structure—the same 26 postures and two breathing exercises performed in the same order for 90 minutes—made it easy to track progress. The heat was increased from the earlier Japanese experiments to a standardized 105 degrees Fahrenheit with 40% humidity.
This specific format became the blueprint for hot yoga studios worldwide. The consistency of the method meant that a practitioner could visit a studio in London, Tokyo, or New York and experience the exact same sequence they practiced at home. This predictability, combined with the "yoga high" produced by the intense heat and endorphin release, helped the style spread rapidly.
Ancient Precedents: The Concept of Tapas
While the modern studio environment is a relatively new invention, the idea of using heat for spiritual and physical transformation is thousands of years old. In Sanskrit, the word tapas refers to "heat," but it also means "discipline," "austerity," or "burning."
Historically, yogis in India practiced tapas to burn away impurities and strengthen the will. One extreme example is panchagni tapas (the five-fire heat), where a practitioner sits in the midday sun surrounded by four fires. This ascetic ritual was a test of mental resolve and a way to transcend physical discomfort.
While modern hot yoga is far more accessible than these ancient austerities, the core philosophy remains similar. The heat serves as a tool to:
- Build mental resilience and discipline
- Focus the mind on the present moment
- Create a sense of "purification" through sweating
- Challenge the practitioner to stay calm in uncomfortable conditions
Key Takeaway: Modern hot yoga is a hybrid of ancient Indian ascetic philosophy (tapas) and 20th-century physical culture, adapted for Western practitioners through the use of artificial heat.
The 26+2 Sequence: A Systematic Approach
The original hot yoga sequence is often referred to as the 26+2. This refers to 26 Hatha yoga postures and two pranayama (breathing) exercises. Each posture is designed to prepare the body for the next, systematically moving fresh, oxygenated blood to every organ, joint, and muscle.
The Standing Series
The first half of a traditional hot yoga class focuses on balance, lung capacity, and warming the spine. Postures like Eagle Pose (Garudasana) and Standing Head-to-Knee Pose (Dandayamana Janushirasana) require immense focus and core stability. The heat helps the muscles stretch safely in these demanding balances, while the heart rate rises significantly.
The Floor Series
The second half of the class moves to the mat. These postures focus on the health of the spine and the internal organs. Many involve "compression," where blood flow is temporarily restricted to certain areas (like the thyroid or the digestive tract) and then "flushed" with fresh blood when the pose is released. This tourniquet effect is a hallmark of the therapeutic claims of the original Ghosh lineage.
The Evolution: Hot Yoga vs. Bikram Yoga
Over the last two decades, the term "hot yoga" has expanded far beyond the original 26+2 sequence. While all Bikram Yoga is hot, not all hot yoga is Bikram. As the practice evolved, teachers began to diversify the movements, heat levels, and atmospheres of their classes.

The Emergence of Vinyasa Flow
In the late 1990s and early 2000s, studios began offering "Hot Power Yoga" or "Hot Vinyasa." Unlike the static, repetitive 26+2 sequence, these classes are dynamic. They link movement with breath in a continuous flow. The temperature in these classes is often slightly lower—typically between 90 and 95 degrees Fahrenheit—to allow for the increased cardiovascular demand of the movement.
Modern Variations and Brands
Several distinct styles have emerged that trace their roots back to the original hot yoga but have added their own philosophy:
- Forrest Yoga: Developed by Ana Forrest, this style emphasizes long holds and core strength in a heated room (around 85 degrees) to heal emotional and physical trauma.
- Baptiste Power Yoga: Founded by Baron Baptiste, this is a vigorous Vinyasa style practiced in a heated environment, focusing on empowerment and "drishi" (focused gaze).
- Modo/Moksha Yoga: Founded in Canada, this style focuses on environmental sustainability and a set sequence of 40 postures, often practiced in a room heated to about 98 degrees.
- CorePower Yoga: A popular American franchise that offers a variety of heated classes, including "Yoga Sculpt," which incorporates weights into the heated environment.

The Science of Practicing in the Heat
The popularity of hot yoga isn't just about tradition; many practitioners swear by the physiological effects of the heat. While some claims—such as the idea that sweating "detoxifies" the liver or kidneys—are not supported by medical science, there are genuine benefits to exercising in a heated room.
Increased Circulation and Flexibility
Heat causes vasodilation, meaning your blood vessels widen. This increases blood flow to the muscles, delivering more oxygen and helping them to relax. This is why many people find they can reach deeper into a stretch in a hot room than in a cool one. For those with tight hamstrings or stiff joints, the heat provides a safer environment to work on range of motion.
Cardiovascular Challenge
Practicing in 105-degree heat increases your heart rate more than practicing at room temperature. The body has to work harder to cool itself down through sweating and increased blood flow to the skin. This turns a relatively low-impact yoga session into a significant cardiovascular workout.
Mental Focus and Resilience
Perhaps the most profound effect of hot yoga is the "mental reset." The intensity of the heat requires total concentration. It is difficult to worry about your to-do list when you are focused on maintaining your balance and breath in a 105-degree room. Many practitioners describe a "yoga buzz" or a feeling of deep calm after class, which researchers attribute to the release of endorphins and the meditative focus required.

Choosing the Right Gear for Hot Yoga
The origin of hot yoga may be in India and Japan, but the gear required for the modern practice is highly specialized. Because you will be sweating profusely, the equipment you choose can make the difference between a focused session and a frustrating one.
When comparing grip, cushioning, and materials, our Yoga Mat Guide can help you evaluate your options.
The Importance of Grip
In a hot yoga class, your mat becomes wet very quickly. A standard mat can become a "slip-and-slide," which is not only distracting but also dangerous for your joints. We recommend choosing a mat with excellent wet-grip capabilities.
Our Para Rubber Yoga Mat is an excellent choice for hot yoga because natural rubber provides a superior grip that actually improves as it gets slightly damp. Alternatively, many practitioners use a Tapas® Original Yoga Mat—the mat that helped build our reputation for reliability—and cover it with a specialized yoga towel to absorb moisture.
Props and Support
Even in a heated room, props are essential for maintaining proper alignment.
- Blocks: Cork blocks are often preferred in hot yoga because they are more stable and less likely to slip when your hands are sweaty compared to foam blocks.
- Straps: A cotton strap can help you maintain reach in poses like Standing Head-to-Knee if your flexibility is still developing.
- Blankets: While you won't need a blanket during the active part of the class, a Mexican or cotton blanket is helpful for staying warm during the final Savasana (Corpse Pose) as your body temperature drops rapidly after the heat is turned off.
Note: Always clean your mat and props immediately after a hot yoga session. The combination of sweat and heat can lead to bacterial growth if the equipment is not disinfected.
Practicing Safely: Listening to Your Body
As with any intense physical activity, hot yoga requires a mindful approach. The origins of the practice were therapeutic, but pushing too hard in the heat can lead to exhaustion.
Hydration is Mandatory
The goal of hot yoga isn't to see how much weight you can lose through sweat; it's to use the heat for flexibility and focus. You must hydrate before, during, and after class. We recommend drinking 16–20 ounces of water with electrolytes about two hours before your session.
Acclimatization
If you are new to heated practice, don't expect to master the full 90 minutes immediately. It can take the body up to two weeks to fully acclimate to exercising in high temperatures. It is perfectly acceptable to sit down on your mat for a few postures if you feel lightheaded or overwhelmed.
Bottom line: The heat should be a tool for your practice, not a source of stress. Always prioritize your breath and your internal signals over the instructions of the teacher.
The Future of the Practice
The landscape of hot yoga continues to shift. While the specific brand of "Bikram Yoga" has faced challenges due to the actions of its founder, the practice itself—the 26+2 sequence and the use of heat—remains a foundational part of global yoga culture. Today, many studios have moved toward more inclusive, trauma-informed, and varied approaches to heated practice.
We see a future where hot yoga continues to integrate with other wellness modalities. From incorporating infrared heat—which warms the body directly rather than just the air—to blending hot yoga with restorative practices, the evolution of heat in yoga is far from over.
Conclusion
The origin of hot yoga is a story of adaptation. It began with the physical culture of Kolkata, was shaped by the freezing winters of Japan, and eventually flourished in the health-conscious culture of Southern California. Whether you practice a strict 26-posture sequence or a flowing hot vinyasa, you are participating in a tradition that uses the element of heat to forge a stronger connection between mind and body.
At Hugger Mugger, we have spent nearly 40 years supporting the yoga community with tools that last. We believe that whether you are practicing in a room that is 70 degrees or 105 degrees, the most important element is your commitment to showing up on the mat. By understanding where these practices come from, we can approach our modern sessions with greater respect and awareness.
