What are the benefits and drawbacks of soaking feet in salt water?
My heel is very painful, and I don't know whether I might have bumped or injured it somehow. A friend mentioned that soaking feet in salt water might help, so I wanted to ask, what are the benefits and risks of soaking feet in salt water?

Benefits of soaking feet in salt water:
1. Promotes blood circulation: Warm salt water can dilate blood vessels and improve blood circulation, helping to relieve leg fatigue and muscle tension.
2. Antibacterial and anti-inflammatory: Salt has natural antibacterial properties, which can help cleanse the skin, reduce the risk of bacterial and fungal infections, and may help prevent conditions such as athlete's foot.
3. Relaxes the body and mind: Soaking feet itself can help relax the body and alleviate daily fatigue. The warmth and mild stimulation of salt water can also promote better sleep.
Drawbacks of soaking feet in salt water:
1. Dry skin: Long-term and frequent use of high-concentration salt water for foot soaks may cause excessive skin dehydration, especially for individuals with dry skin, potentially worsening dryness issues.
2. Allergic reactions: Some individuals may be sensitive to salt or certain types of salt, which could lead to allergic symptoms such as redness and itching after use.
3. Caution for patients with cardiovascular diseases: For individuals with heart disease or hypertension, prolonged soaking in excessively hot water may increase the burden on the heart and should be approached with caution.
