Sadhguru's Summer Heat Remedy: What Experts Say About His Cooling Claims

Spiritual leader Sadhguru has sparked widespread discussion online after sharing a simple remedy to reduce “excess body heat” during the summer months, prompting health experts to weigh in on the scientific validity of such claims. In a recent video posted on Instagram, Sadhguru suggested that certain physical sensations, such as a feeling of heat in the eyes or difficulty urinating, may indicate excess heat in the body. He recommended remedies including consuming ash gourd juice, eating green gram, or applying castor oil to the navel or behind the ears, claiming these could cool the system within minutes.

The video quickly gained traction, contributing to Sadhguru trending on search platforms for over 24 hours. His statements, presented as quick and accessible solutions for heat-related discomfort, resonated with many viewers seeking relief during rising summer temperatures. However, the simplicity and immediacy of the suggested remedies also raised questions among medical professionals about their effectiveness and scientific grounding.

To examine these claims, dietitian Amreen Sheikh, chief dietitian at KIMS Hospitals in Thane, clarified that what is commonly referred to as “body heat” is not a medically defined condition. Instead, she explained, such symptoms are often linked to dehydration, acidity, or the body’s natural response to high environmental temperatures. During summer, the body tends to lose fluids and electrolytes more rapidly, leading to fatigue, irritability, and digestive issues, which may be misinterpreted as excess internal heat.

Sheikh acknowledged that certain traditional foods mentioned by Sadhguru, such as ash gourd and green gram, can support hydration and overall nutrition. However, she cautioned against claims of immediate or dramatic cooling effects. According to her, the human body regulates temperature through complex physiological processes, and no topical application—such as castor oil on specific body parts—has proven scientific evidence to support rapid cooling within minutes.

Experts instead emphasize sustainable and evidence-based approaches to managing heat. These include maintaining adequate hydration, consuming water-rich foods like watermelon, cucumber, and coconut water, and opting for lighter meals that are easier to digest. Practices such as drinking buttermilk, lemon water, and eating fresh seasonal fruits can help replenish lost fluids and maintain electrolyte balance, while also supporting digestive health during hot weather.

Health professionals also warn against common misconceptions, such as relying on extremely cold beverages or a single “superfood” to counter heat. Such practices may disrupt digestion or cause discomfort rather than provide relief. Instead, experts advise individuals to listen to their bodies, avoid long gaps between meals, and make consistent, balanced dietary choices. They stress that while traditional remedies can complement a healthy routine, they should not replace scientifically supported methods or professional medical advice.
