The immune system is a complex network of cells, tissues, and organs that work together to defend the body against harmful invaders, such as pathogens (disease-causing microorganisms), abnormal cells, and foreign substances. Its primary function is to protect the body from infections and diseases. Weak immunity presents some evident issues that one shouldn’t ignore. Here is an overview of the signs and what can be done to manage low immunity.

1. Frequent infections and fatigue
Individuals with weakened immunity are always at risk of recurrent infections like colds and sinusitis caused by respiratory viruses, as well as urinary tract and skin infections. Their healing is compromised as common wounds like cuts, bruises, and injuries take longer to heal than usual. All this leads to persistent tiredness that significantly affects a person’s quality of life.

2. Allergies and autoimmune responses
An overactive or dysfunctional immune system triggers allergies that manifest as allergic rhinitis, asthma, or skin reactions. Frequent mouth or genital ulcers also indicate an underlying concern that shouldn’t be ignored. The immune system can also mistakenly attack healthy cells and tissues, leading to the development of autoimmune diseases like rheumatoid arthritis, lupus, and multiple sclerosis. Further, chronic gastrointestinal issues like diarrhea, bloating, or frequent infections in the gut can be linked to a compromised immune system.

3. Skin rashes and chronic conditions
Persistent or recurring skin rashes, eczema, or psoriasis can be associated with immune system dysfunction. Weak immunity further increases susceptibility to fungal infections like thrush (oral or genital candidiasis) or athlete’s foot. A compromised immune system may have difficulty detecting and destroying cancerous cells, increasing the risk of cancer development. Any other illnesses that persist longer than expected, even minor infections, may indicate a weakened immune response.

Maintaining a strong immune system is crucial for overall health and resilience against illnesses. Here are some expert suggestions for improving immunity:

1. Balanced nutrition
Nutritionists advise eating well-balanced meals with fruits, vegetables, whole grains, lean proteins, and healthy fats. These foods provide essential vitamins, minerals, and antioxidants that support immune function. Also, it’s important to drink plenty of water to keep the body hydrated, support circulation, and boost the immune system. Further, consider incorporating probiotic-rich foods like yogurt, kefir, sauerkraut, and kimchi to support a healthy gut microbiome, which plays a role in immune function.

2. Regular physical activity and ample rest
Engage in regular physical activity, as it can help boost the immune system by promoting good circulation and reducing inflammation. Exercise also promotes endorphins that help keep one’s mood in check. Further, doctors recommend getting at least 7-9 hours of quality sleep per night. Sleep is essential for immune system recovery and function. Note that chronic stress can also weaken the immune system. To overcome stress, practice stress-reduction techniques like meditation, yoga, deep breathing exercises, or mindfulness.

3. Good general and food hygiene
Washing hands frequently with soap and water and practicing good hygiene to prevent spreading infections are essential. One must stay up-to-date with recommended vaccinations that protect against various diseases and strengthen the natural immune response. Also, it is vital to practice safe food handling and cooking to prevent foodborne illnesses from invading and weakening the immune system.
