Focus on your breath
The way you breathe may help keep you warm, and it’s more than blowing warm air on your hands. There is a Tibetan practice called vase breathing that is thought to raise body temperature, although you might need to put some work into it and also use in combination with visualization and meditation. “Vase breathing is an element of the g-tummo meditation practices of Indo-Tibetan Yogis,” explains Laura Stix, a naturopathic doctor and clinical hypnotherapist in Ontario, Canada. “It is a sacred practice and research to date does support the efficacy of this breathing technique to increase body temperature, though it is not clear how exactly it does this.” She explains that vase breathing includes holding the breath and contracting abdominal and pelvic floor muscles. But there’s a secret to this. The key is to do this in a manner that makes your protruding belly take the shape of a pot-like vase shape. Additionally, she says that it’s also helpful to practice visualization while doing this. Imagine warm energy filling your body. A study shows that without visualization, people can only do “Forceful Breath vase breathing for a limited time, resulting in limited temperature increases in the range of normal body temperature,” according to a 2013 study in PLoS One.

Bundle up the smart way
Layers trap heat and help prevent sweating (which makes you feel colder). The U.S Department of Labor’s Occupational Safety and Health Administration notes the importance of dressing in layers to stay safe in cold weather. They suggest wearing at least three layers of loose-fitting clothes to provide ideal insulation. Specifically, they say to wear an inner layer of wool, silk, or synthetic material. This keeps moisture from the body. Second, wear a middle layer made of wool or synthetic material. This acts as an insulator when wet. Finally, wear an outer wind and rain protection layer for ventilation. Resist the urge to wrap clothes tightly, too. They add doing so reduces blood circulation, which is necessary to keep your extremities warm.
