Introduction
Walking into a heated yoga studio for the first time is a sensory experience unlike any other. The wall of warmth hits you immediately, promising a practice that is as much a mental challenge as it is a physical one. You might find yourself wondering, as you wipe away the first beads of sweat, where this tradition actually began. Was it an ancient practice passed down through centuries in the heat of India, or is it a modern innovation designed for the fitness-focused world?
At Yoga Design Lab, we believe that understanding the "why" and "where" behind your practice deepens your connection to the mat. In this article, we will explore the 1970s origins of hot yoga, the cultural shifts that brought it to the West, and how it has evolved into the diverse styles we see today. From the original 26-pose sequence to modern, artful flows, we are here to guide you through the steamy history of this impactful practice.

Quick Answer: Modern hot yoga was invented in the early 1970s by Bikram Choudhury while he was teaching in Japan. He began using heaters to replicate the humid climate of India, eventually bringing the concept to the United States in 1971.
The Birth of the Heated Studio: Japan in the 1970s
While yoga itself is thousands of years old, the specific practice of "hot yoga" in a climate-controlled room is a relatively recent development. The story begins in Japan during the early 1970s. A teacher named Bikram Choudhury was leading classes and noticed a curious habit among his Japanese students. Many would visit saunas during their lunch breaks before or after their yoga sessions.
Intrigued by the relationship between heat and physical performance, he began experimenting with space heaters in his yoga room. Initially, the temperatures were modest, set to about 82 degrees Fahrenheit (28 degrees Celsius). He wanted to recreate the natural humidity and warmth of his hometown, Calcutta, India. He observed that his students were able to stretch more deeply and felt a greater sense of physical exertion when the room was warm.
As he saw the positive feedback from his students, the temperature began to climb. He noticed that the sweat produced by the heat made the practice feel more intense and rewarding. By the time he moved his operations to the United States, the concept of a "hot" room was becoming central to his methodology.

The Move to the United States
In 1971, the practice made its way to Los Angeles, California. This was a pivotal moment in yoga history. The United States was experiencing a burgeoning interest in Eastern philosophy and alternative health. Opening the Bikram Yoga College of India, the founder introduced a very specific, rigid system.
This original style consisted of exactly 26 asanas (poses) and two pranayama (breathing exercises). Each class lasted 90 minutes and took place in a room heated to 105 degrees Fahrenheit with 40% humidity. The consistency of this format—often called the "McDonald’s of yoga"—meant that a student could walk into a studio in Los Angeles or London and receive the exact same instruction.
By the 1980s and 90s, hot yoga had become a Hollywood phenomenon. High-profile celebrities and athletes flocked to these steamy rooms, drawn by the promise of intense physical conditioning and flexibility. This era cemented hot yoga's place in the global fitness landscape, moving it from a niche interest to a mainstream powerhouse.
Historical Precedents: Heat in Ancient India
While the modern "studio" version of hot yoga is only about 50 years old, the use of heat as a spiritual and physical tool has ancient roots. In India, yogis have long used the environment to test their discipline and willpower. One extreme example is a practice called panchagni tapas (five fire heat).
In this ritual, an ascetic—someone who renounces worldly involvement for spiritual exploration—sits surrounded by four fires under the heat of the midday sun. The heat is considered a "fire sacrifice" intended to strengthen resolve and transcend physical suffering. This is an extreme form of tapas, a Sanskrit term often translated as "heat," "discipline," or "burning effort."
Beyond these intense ascetic practices, traditional Ayurvedic medicine—India’s ancient system of natural healing—has used steam baths for centuries. These baths were used to induce sweating for health maintenance and to support the body’s natural recovery processes. While these traditions are not "hot yoga" in the modern sense, they highlight a long-standing human belief in the transformative power of heat.
The Influence of Bishnu Ghosh
To understand the specific poses used in early hot yoga, we must look at Bishnu Ghosh. He was the younger brother of Paramahansa Yogananda, the famous author of Autobiography of a Yogi. Ghosh was a well-known physical culturist and weightlifter in Calcutta who operated a school focused on physical development through yoga.
Ghosh’s approach was unique because it blended traditional Hatha yoga (a system of physical poses and breathing) with bodybuilding and therapeutic exercises. He developed sequences designed to heal the body from injuries and chronic ailments. Many of the 26 poses found in the original hot yoga sequence were directly adapted from Ghosh’s teachings. This lineage emphasizes the idea that yoga is a tool for physical restoration and structural alignment.
The Evolution of Diverse Styles
For several decades, the term "hot yoga" was synonymous with one specific brand and sequence. However, as the practice grew, other teachers began to innovate. They wanted to combine the benefits of a heated room with different styles of movement, such as Vinyasa (a style where movements are synchronized with breath to form a "flow").
Power Yoga and Vinyasa
Teachers like Baron Baptiste and Bryan Kest were instrumental in the 1990s in creating "Power Yoga." These classes were often heated, but they moved away from the rigid 26-pose sequence. Instead, they focused on a more athletic, varied flow that kept the heart rate up and challenged the body in new ways. You can also compare different temperature ranges in our guide to hot yoga studio temperatures.
Forrest Yoga
Developed by Ana Forrest in the early 1980s, this style is practiced in a room heated to about 85 degrees. It focuses on long-held poses, core strength, and emotional release. It was one of the first major deviations from the original hot yoga format to gain widespread popularity.
Modo and CorePower
In the early 2000s, new franchises like Modo Yoga (founded in Canada) and CorePower Yoga began to emerge. These studios emphasized community, sustainability, and accessibility. They offered various heat levels and sequences, allowing students to choose the intensity that suited them best.
Key Takeaway: While "Bikram Yoga" refers to a specific 26-pose sequence and a 105-degree room, "Hot Yoga" is now a broad category that includes many different styles, temperatures, and philosophies.
Why the Heat Matters: The Science of Sweat
The primary reason practitioners seek out heated rooms is the impact on the physical body. When you practice in a hot environment, several physiological changes occur:
- Vasodilation: The heat causes your blood vessels to widen. This increases blood flow to the muscles, delivering more oxygen and helping the body move with greater ease.
- Muscle Elasticity: Heat allows your muscles and connective tissues to become more pliable. This can support a deeper range of motion and help you feel less "stiff" during your practice.
- Cardiovascular Challenge: Your heart has to work harder to cool the body down. This turns a relatively static yoga practice into a more intense cardiovascular workout.
- Hyperthermic Conditioning: Regular exposure to heat can help the body become more efficient at cooling itself. Some research suggests this can improve endurance and support the production of heat shock proteins, which aid in muscle repair.
It is important to address a common myth: the idea that sweating "detoxifies" the body. While it feels incredibly refreshing, sweat is primarily made of water, salt, and minerals. Your liver and kidneys are the organs responsible for filtering toxins. However, sweating is an excellent cooling system, and the increased circulation from a hot class can certainly make you feel revitalized.

Navigating the Challenges of Hot Yoga
Hot yoga is not without its hurdles. The most common issue practitioners face is slipping. In a standard yoga class, a regular mat might suffice. But in a 100-degree room, your mat can quickly turn into a "slip-and-slide" as sweat pools on the surface.
This exact challenge is what led our founder, Chad Turner, to create the signature Combo Mat. While practicing in a humid studio in Ubud, Bali, he noticed everyone struggling with bunching towels and slippery surfaces. He envisioned a better way: a premium natural rubber base bonded to a soft, absorbent recycled PET microfiber top.
This design functions as a mat and towel in one. The grip is moisture-activated, meaning the more you sweat, the better you stick. This innovation allows you to focus on your Drishti (focused gaze) and alignment rather than worrying about your hands sliding in Adho Mukha Svanasana (Downward-Facing Dog).
Essential Gear for the Heat
If you are planning to join the millions of people who practice hot yoga, having the right equipment is essential for safety and comfort.
- The Right Mat: Look for a mat specifically designed for high-sweat environments. Our Combo Mat or the Travel Combo Mat (at a thinner 1.5mm) are favorites for hot yoga because they eliminate the need for a separate towel.
- Hydration: This is non-negotiable. You should drink water throughout the day before your class, not just during it.
- Towel: Even with a high-grip mat, a small hand towel is helpful for wiping sweat from your eyes. Explore the all-towel collection for additional options.
- Breathable Clothing: Opt for moisture-wicking fabrics that won't feel heavy when wet. Avoid heavy cotton, as it absorbs sweat and becomes cumbersome.
Safety Precautions for a Hot Practice
Because of the intensity of the heat, certain individuals should take extra care or avoid hot yoga altogether.
- Pregnancy: The increased core body temperature can be risky for fetal development. Most experts recommend avoiding hot rooms during pregnancy and opting for prenatal-specific classes at room temperature.
- Heart Conditions: The cardiovascular strain of a 105-degree room can be significant. Always consult a doctor if you have a history of heart issues or high blood pressure.
- Dehydration and Heat Stroke: If you feel dizzy, nauseous, or lightheaded during class, it is crucial to listen to your body. Sit down in Balasana (Child’s Pose) or step out of the room to cool down. There is no shame in taking a break.
Sustainability and the Future of Hot Yoga
As the practice of hot yoga continues to grow, so does our responsibility to the planet. Many early yoga mats were made from cheap, toxic materials like PVC, which do not biodegrade and can off-gas harmful chemicals in a heated room.
We believe that the gear you use should be as pure as your intentions. This is why our mats are made from natural tree rubber and recycled plastic bottles. Our printing process uses water-based inks, ensuring that no toxic smells are released when the room gets hot. Sustainable choices allow us to protect the environments that inspire our nature-inspired designs, from the lush forests of Bali to the vibrant sunsets of the Pacific. Learn more about our sustainability commitment.
Bottom line: Modern hot yoga was born from a desire to replicate the heat of India in a modern studio setting. It has evolved from a rigid 26-pose system into a diverse global movement that prizes flexibility, endurance, and mental grit.

FAQ
When exactly was the first hot yoga class taught?
The first instances of using heaters in a yoga studio occurred in Japan in the early 1970s. By 1971, the concept was formally introduced to the United States with the opening of a dedicated school in Los Angeles.
Is hot yoga the same as Bikram yoga?
Not exactly. Bikram yoga is the original form of hot yoga and follows a strict 26-pose sequence in a 105-degree room. "Hot yoga" is now used as a broad term for any style of yoga—including Vinyasa, Yin, or Power yoga—performed in a heated environment.
Why do people practice yoga in the heat?
Practitioners use heat to increase muscle elasticity, which allows for deeper stretching and a reduced risk of certain types of strain. The heat also creates a cardiovascular challenge and induces heavy sweating, which many find mentally and physically refreshing.
How much water should I drink for a hot yoga class?
Hydration should begin hours before your class starts. Aim to drink at least 16 to 20 ounces of water two hours before practice, sip water during class as needed, and replenish with electrolytes afterward to replace what was lost through sweat.
