When temperatures climb and your body feels overheated, cooling breathwork techniques offer a natural way to lower your internal temperature, calm your nervous system, and restore mental clarity. Sheetali and Sitkari are two classical pranayama practices specifically designed to cool the body, and they have been used by yogis for centuries to manage heat, reduce irritability, and bring the mind into a state of calm focus.
Unlike heating breathwork techniques such as Kapalabhati and Surya Bhedana, which stoke internal fire and energize the system, Sheetali and Sitkari work by drawing air across the moist surfaces of the tongue and mouth, creating an evaporative cooling effect before the breath reaches the lungs. The result is a noticeable drop in perceived body temperature within just a few rounds.
In this guide, you will learn the precise technique for both Sheetali and Sitkari pranayama, understand the science behind why they work, discover when and how to incorporate them into your daily routine, and explore complementary practices that amplify the cooling effect.
The Science of Cooling Breathwork
Your body regulates temperature through a combination of sweating, vasodilation, and behavioral changes like seeking shade. Breathwork adds another layer to this system by directly influencing the autonomic nervous system. When you practice slow, controlled inhalation through a curled tongue or clenched teeth, the incoming air passes over moisture on the oral surfaces, cooling it through evaporation before it enters the respiratory tract. This cooled air stimulates the vagus nerve, which in turn activates the parasympathetic (rest-and-digest) branch of the nervous system.
The parasympathetic activation lowers heart rate, reduces blood pressure, and decreases the production of stress hormones like cortisol. These physiological changes collectively create a sensation of coolness and calm that goes beyond simple temperature regulation. Studies on pranayama have shown that even short sessions of controlled breathing can measurably reduce oral temperature and decrease sympathetic nervous system activity.
Sheetali Pranayama: The Cooling Breath
Sheetali (sometimes spelled Shitali) comes from the Sanskrit root “sheetal,” meaning cool or soothing. This technique involves inhaling through a curled tongue, which acts as a natural cooling channel for the incoming air.
How to Practice Sheetali
Sit in a comfortable position with your spine tall. You can sit cross-legged on the floor, on a cushion, or in a chair. Close your eyes and take a few natural breaths to settle in. When you are ready, open your mouth slightly and curl the sides of your tongue upward to form a tube or straw shape. If you cannot curl your tongue (this is a genetic trait and approximately 35 percent of people cannot do it), you will use Sitkari instead, which is described in the next section.
Inhale slowly and deeply through the curled tongue, drawing the air in as if you are sipping through a straw. Feel the coolness of the air on your tongue and the roof of your mouth. At the top of the inhalation, close your mouth, bring your tongue to the roof of your mouth, and exhale slowly and completely through your nose. That is one round. Practice eight to twelve rounds, gradually lengthening both the inhalation and exhalation as you become more comfortable.
Key Points for Sheetali
Keep the inhalation smooth and steady rather than gasping. The cooling effect comes from the slow, controlled passage of air, not from volume or speed. If you feel dizzy at any point, return to normal breathing for a few cycles before resuming. Practice on an empty stomach or at least two hours after a meal for the best results. Sheetali is most effective when practiced during the hottest part of the day or immediately after physical activity.
Sitkari Pranayama: The Hissing Breath
Sitkari is the companion technique to Sheetali and produces a similar cooling effect through a slightly different mechanism. Instead of curling the tongue, you draw air through the gaps in your clenched teeth, producing a soft hissing sound. This makes Sitkari accessible to everyone, regardless of whether they can curl their tongue.
How to Practice Sitkari
Sit comfortably with your spine erect and your shoulders relaxed. Bring your upper and lower teeth together gently, then part your lips to expose the teeth. Inhale slowly through the gaps between your teeth, allowing the air to pass over the wet surfaces of your tongue and gums. You will hear a gentle hissing or sipping sound, which gives this technique its name. Once your lungs are full, close your mouth, place your tongue on the roof of your mouth, and exhale slowly through your nose. Repeat for eight to twelve rounds.
Key Points for Sitkari
If you have sensitive teeth, the cool air passing over them may cause discomfort. In this case, try placing the tip of your tongue just behind your upper front teeth to partially shield them while still allowing air to flow over the sides of the tongue. Like Sheetali, Sitkari should be practiced with a slow, controlled inhalation. The exhale through the nose allows the body to retain some warmth in the nasal passages, creating a balanced cooling effect rather than an extreme one.
When to Use Cooling Breathwork
Cooling pranayama is most beneficial in the following situations. During hot weather, practicing five to ten minutes of Sheetali or Sitkari can provide noticeable relief from heat-related discomfort. After vigorous exercise or a heating yoga practice like Ashtanga or Power Vinyasa, a few rounds of cooling breath help the body transition from exertion to recovery. When you feel emotionally heated, whether from anger, frustration, or anxiety, these techniques work remarkably well to downregulate the stress response. If you are looking for more anxiety management tools, our yoga for anxiety guide offers complementary sequences.
Cooling breathwork is also helpful before bed on warm nights. When combined with the relaxation techniques from our breathwork for sleep guide, Sheetali or Sitkari can help lower your core temperature enough to facilitate the onset of sleep. Research shows that a slight drop in body temperature is one of the primary triggers for melatonin production and sleep initiation.
When to Avoid Cooling Breathwork
There are a few situations where cooling pranayama is not recommended. During cold weather or if you already feel chilled, these techniques can lower body temperature too much. People with respiratory conditions like asthma or chronic bronchitis should approach with caution, as the cool air may trigger bronchospasm in sensitive individuals. If you have low blood pressure, the parasympathetic activation from extended cooling breathwork could cause lightheadedness. In these cases, gentler techniques like Yoga Nidra may be a better choice for relaxation without the cooling component.
A Complete Cooling Breathwork Session
Here is a ten-minute cooling breathwork practice you can use whenever you need to lower your temperature or calm your mind. Begin by sitting comfortably and closing your eyes. Spend the first two minutes simply observing your natural breath without changing it. Notice the temperature of the air as it enters and exits your nostrils.
For the next three minutes, practice Sheetali (or Sitkari if you cannot curl your tongue). Inhale for a count of four through the curled tongue, then exhale for a count of six through the nose. Gradually extend the counts as you feel comfortable, perhaps reaching an inhale of six and an exhale of eight.
After three minutes of Sheetali or Sitkari, transition to Nadi Shodhana (alternate nostril breathing) for three minutes. This balancing technique helps integrate the cooling effect and creates equilibrium between the left and right energy channels. Inhale through the left nostril for four counts, hold for four counts, and exhale through the right nostril for six counts. Then inhale through the right nostril, hold, and exhale through the left.
Finish with two minutes of natural breathing, eyes still closed. Notice how your body feels compared to when you started. Most practitioners report a noticeable sense of coolness in the mouth, throat, and chest, along with a quiet, settled quality to the mind. This practice pairs beautifully with the seated meditation techniques found in our restorative yoga guide.Integrating Cooling Breathwork Into Your Yoga Practice
Cooling breathwork fits naturally at the end of a yoga asana session, especially after a vigorous or heating practice. After your final pose and before Savasana, sit for three to five minutes of Sheetali or Sitkari to bring your body temperature and heart rate down. This transition helps deepen the relaxation response during Savasana and makes the entire practice feel more complete.
You can also use cooling breathwork as a standalone practice, separate from asana. On particularly hot days, or during stressful periods when you need a quick reset, even two to three minutes of Sheetali or Sitkari at your desk or in your car (while parked) can make a meaningful difference. For another quick office-friendly practice, check out our 5-minute desk yoga guide.
By adding Sheetali and Sitkari to your pranayama toolkit, you gain a simple, portable, and effective way to manage heat, stress, and emotional intensity. These ancient techniques require no equipment, no special setting, and no more than a few minutes of your time, yet they deliver profound shifts in how your body and mind feel.
