If you find yourself catching colds or infections more frequently than before, it could be a sign that your immune system is weakening.
The immune system is not only responsible for fighting infections but also plays a role in wound healing. If your wounds take longer to heal than usual, it may indicate a decline in immune function.
Persistent fatigue and lack of energy might be your body's way of telling you that it is struggling with infections or that your immune system is not strong enough.
The immune system is closely related to digestive system health. Frequent diarrhea, constipation, or stomach discomfort could be signs of a weakened immune system.
Stress and mood swings can affect immune system function. If you find it hard to cope with stress or experience mental health issues, it might be related to a decline in immunity.
