Cold extremities can negatively affect immune response and metabolism. “Onkatsu” (body warming) focuses on lifting baseline temperature through mindful bathing habits and dietary choices.
Diet-Based Body Warming
Ginger, leeks, and root vegetables (carrots, burdock) are known as warming foods. A warm soup or tea in the morning wakes up your digestive organs, stimulating circulation throughout the day.
Effective Bathing Methods
Choose a 38-40°C half-body bath lasting 15-20 minutes rather than a quick shower. Warm water dilates blood vessels, improving circulation throughout the body. Add ginger bath powder or Epsom salts to enhance the warming effect and promote deeper relaxation.
Daily Cold-Proofing Tips
Keep your abdomen, ankles, and wrists covered to prevent heat loss. During desk work, stand up and walk every hour to stimulate blood flow. Wear leg warmers or a belly wrap while sleeping to maintain warmth throughout the night.
Conclusion
Onkatsu (body warming) is simple to practice through diet, bathing, and daily habits. Since cold sensitivity can undermine overall health, adopting warming routines boosts immunity, metabolism, and daily comfort.
