There are taboos in safe foot soaking

1. The foot soaking time should not be too long, preferably 15-30 minutes.

When soaking your feet, blood will flow to your lower limbs, which may lead to insufficient blood supply to the brain. If patients with cardiovascular and cerebrovascular diseases and the elderly feel chest tightness or dizziness, they should temporarily stop soaking their feet and take a rest. Diabetic patients have poor peripheral sensory ability, so family members should test the water temperature first to prevent burns.

2. It is not advisable to soak your feet within 1 hour after a meal.

After eating, most of the blood in the body flows to the digestive tract. If you soak your feet in hot water immediately after the meal, the blood that should have flowed to the digestive system will flow to the lower limbs instead. Over time, it will affect digestion and absorption and lead to Nutritional deficiencies. Therefore, it is best to soak your feet one hour after a meal.

3. It is best to use a wooden basin for foot soaking with traditional Chinese medicine.

The chemical components in metal basins such as copper basins are unstable and can easily react with the tannic acid in traditional Chinese medicine to produce iron tannate and other harmful substances, which greatly reduces the efficacy of the medicine.

4. Children should not soak their feet in overheated water for a long time.

Because the arch of the foot begins to form in childhood, attention should be paid to protecting it from an early age. If children's feet are often washed with hot water, the ligaments on the soles of the feet will become loose, which is not conducive to the formation and maintenance of the arch of the foot and may easily lead to flat feet.

5. Women should not use traditional Chinese medicine to soak their feet during menstruation.

Women’s menstrual problems are more complicated. If you can’t identify the cause, you will use traditional Chinese medicine to soak your feet. Not only will it not have a soothing effect, it may also aggravate symptoms such as dysmenorrhea. Therefore, if women want to use traditional Chinese medicine to soak their feet to treat menstrual health problems such as dysmenorrhea, it is best to consult a doctor and take appropriate medication according to their own conditions.
