WBCs, or white blood cells, play a crucial role in your immune system. To naturally boost their levels, focus on a balanced diet rich in fruits, vegetables, whole grains, and lean proteins. Regular exercise, adequate sleep, and managing stress are also beneficial. Signs of low white blood cell counts can include frequent infections, fatigue, and fever. Various factors, such as certain medical conditions or medications, can affect your WBC count. If you have concerns, I recommend consulting a physician for personalized advice and thorough evaluation. They can provide guidance tailored to your specific health needs.
