Certainly, your struggle with maintaining body heat likely points to an imbalance in your doshas, specifically a vata imbalance which is known for its cold, dry, and light qualities. An underlying reason could indeed be linked to agni, or digestive fire, that influences warmth throughout the body. Here, practical steps combining dietary adjustments and lifestyle practices can make a real difference.
First, focus on warming and nourishing foods. Introducing warm, cooked meals enriched with spices that boost your internal heat can be very helpful. Spices like ginger, cinnamon, and turmeric have warming properties—consider adding them to your meals and drinks. Soups, stews, and broths especially during colder months support your metabolism, assisting in regulating body heat. Limit raw, cold, and icy foods as they intensify vata’s cooling effect.
Additionally, ghee and other healthy fats are essential to add to your diet. They lubricate the body internally, helping in maintaining warmth and nourishing the tissues or dhatus, specifically rasa and rakta (blood and plasma). Moderate amounts of ghee in your cooking can serve this purpose.
Consider your meal timing too. Eating consistent meals at regular intervals helps maintain digestive fire. Avoid skipping meals as this contributes to vata imbalance.
Digestive health plays a critical role, and it sounds like your gut could need attention. Herbal teas like cumin, coriander, and fennel can support digestion. Prepare a tea by boiling equal parts (about a teaspoon each) of these seeds in water and drinking it warm after meals.
Additionally, incorporate daily practices that keep vata in check like oil massage or abhyanga with sesame oil followed by a warm shower. This not only provides external warmth but also nourishes the skin and calms vata-related issues.
If these practices don’t improve your condition, or if you experience persistent symptoms, seeking personalized advice from a qualified Siddha-Ayurvedic practitioner is important to rule out any serious underlying concerns.
