First of all, it should be clear that the baby’s cold hands and feet are mainly caused by the reduction of activities, the baby outdoor activities, activities at home is also very little, often playing electronic devices, there is no certain activity space, so cause the baby blood circulation is not enough. Mothers and fathers bring their babies home from the cold outdoors and find that cold hands and feet do not allow them to move and come back first with hot water, which is not the right approach, the correct approach should be to take the baby to move around the room or climb the stairs, so that its heart and lungs exercise, so that the baby’s cardiac output and lung capacity can increase. You can also run more, do games, etc., because more games that move the limbs can promote blood circulation. This is also true outdoors, where running up and moving often does not occur. The cold hands and feet of babies are mainly caused by insufficient cardiac output and lung capacity, so they should be properly exercised. If you can do more movement, cold hands and feet will be very good solution, if the above methods are used after the baby still cold hands and feet, then you should go to the hospital for pulse diagnosis, do a routine check to see if there is weakness, consume some qi-supplementing herbs for conditioning, this problem can be solved.
