8 common signs of a weak immune system

The immune system is a natural defense mechanism of the human body that protects against harmful microorganisms such as bacteria and viruses. Although it functions well in healthy individuals, it may fail to work at times, making them more vulnerable to infections and illnesses. Additionally, an overactive immune system can result in autoimmune conditions like psoriasis and multiple sclerosis. Therefore, one must look for signs of a weak immune system to ensure necessary treatment.

Common signs of a weak immune system
High-stress levels
According to American Psychological Association, when an individual goes through long periods of stress, it can adversely affect their immune system. This is because, as stress levels in the body increase, it leads to a simultaneous decrease in lymphocytes – white blood cells ( WBC) that aid in the fight against infections.

Although this may seem harmless, this decrease in WBCs can cause one to be at an increased risk for virus or bacteria-related issues such as the common cold.

Besides this, chronic stress or frequent episodes of stress can worsen autoimmune conditions like ulcerative colitis and rheumatoid arthritis.

Persistent colds
Most people can be affected by the common cold 2-3 times a year. In such cases, these individuals may bounce back to normalcy in a week or a maximum of 10 days.

A person’s immune system is critical for their survival. People tend to have longer and healthier lives when their immunity is consistently strong. Good, nutritious food is important in maintaining one’s immune system’s strength. On the other hand, certain foods can have a detrimental effect on one’s immunity. Sugar is one such food element that weakens the immune system. Here are some signs of a poor immune system due to excessive sugar intake: High-stress levels Stress has always been associated with weakened immunity in people. That is why, after a particularly stressful day at work, people are more likely than not to call in sick the following morning. Stress results from weakened immune responses caused due to illness or other bodily conditions. Stress tends to decrease the count of the body’s lymphocytes, the white blood cells responsible for battling infection. Sugar consumption causes a stress response in one’s body. Anxiety and stress are closely linked with a person’s blood sugar rising or falling. Blood sugar triggers various mental health issues, such as depression, insomnia, a lack of focus, memory issues, a constant feeling of being overwhelmed, inflammation, and other issues. A reason for these problems is that sugar suppresses the hypothalamic-pituitary-adrenal (HPA) axis in a person’s brain.

These spots are the result of bleeding under the skin’s surface. In leukemia, the bone marrow produces abnormal white blood cells, which can interfere with normal blood clotting. This can lead to the development of petechiae, as the tiny blood vessels under the skin become more fragile and can break more easily. These spots can appear on various parts of the body, such as the arms and legs, and may be painless. Fatigue and weakness Individuals with leukemia may experience persistent fatigue and weakness, even after a full night’s sleep of about 7 to 8 hours.
