As the severe cold wave continues to disrupt life in Delhi, Punjab, and Rajasthan, relying solely on electric heaters isn't always feasible due to power cuts or high bills. Staying warm is actually a biological process of thermoregulation. Here are six natural, low-tech hacks recommended by medical research to keep your core temperature up as we navigate the tail end of winter 2026 .
1. The "Muffler Hack": A significant amount of blood flows through the neck. By wrapping a scarf or muffler around your neck, you protect the carotid arteries. Keeping this area insulated ensures the blood reaching your brain remains warm, tricking the brain into allowing warm blood to flow back to your extremities .
2. Isometric Exercises: When you shiver, your muscles contract to generate heat. You can mimic this intentionally. If you're stuck in a cold office, try tensing and releasing your glutes, thighs, and core for 30 seconds. This "invisible" exercise raises core body temperature without making you sweat (which would later make you colder) .
3. The Layering Sandwich: Avoid one super-thick sweater. The goal is to trap "dead air." Wear a snug synthetic or silk base layer (to wick moisture), a woolen middle layer (for insulation), and a windproof outer shell. This is more effective than any single piece of clothing .
4. Humidity Control: Dry air feels colder than humid air because it accelerates evaporation from your skin. Place a shallow bowl of water near your room heater or use a humidifier. Maintaining 40-50% humidity indoors helps your skin retain its natural oils and keeps the "chilled" feeling away .
5. Core Protection: If your torso is cold, your body pulls blood away from your hands and feet to protect the heart and lungs. Wear a thermal vest or a sleeveless "gudri" (quilted vest) to keep the core safe, and your fingers will naturally feel warmer .
6. Golden Hour Sun: Between 11 AM and 1 PM, step out for 20 minutes. The infrared rays from the sun penetrate the skin and warm tissues directly, providing deep-seated heat that lasts longer than a space heater .
