If the indoor temperature is controlled at about 20℃, you can use heating or electric heater, but to avoid the air being too dry, open the window for ventilation or use humidifier in time.
Wear comfortably and keep warm.
Choose cotton or wool clothes, pay attention to protect key parts such as waist, abdomen and feet, and avoid wearing them too tightly or too loosely, which will affect blood circulation and breathing.
