2. Slow healing

We all cut ourselves while cooking or scratch our knees while getting around the furniture, and the healing process should not take longer than the usual 2 to 3 days. If your wounds take longer than normal to heal, it could be a sign that your immune system is failing to do its job properly.

None of us has superpowers to heal wounds within a couple of hours, but when you cut yourself a little one week ago and the wound still bleeds if deranged, then your immune system is not capable of healing it. Sometimes it is also about bacteria or viruses that are more serious than a small scratch. When your body is dealing with bacteria, it needs to be capable of taking it out.
