Many disorders can affect the immune system, which is a collection of organs, tissues, and cells that work together to defend the body against infection and disease. Several problems can occur with the immune system, and these may be due to:

  • congenital abnormalities
  • a disease that weakens the immune system, such as HIV
  • an overactive immune system, which may cause allergic reactions
  • a fault that causes the immune system to attack healthy tissue, such as an autoimmune disorder

It is possible to get sick regularly when the immune system is not functioning correctly. The reason for this is that the body is unable to fight off germs, such as bacteria, properly.

If an infection occurs, it can take longer than usual to recover. It is possible to acquire another illness during this time, which may cause a constant feeling of being unwell.

It will be necessary to treat any disease affecting the immune system, and this will usually involve different types of medication.

Many manufacturers make products that they claim can boost the immune system, but it is very difficult to promote its activity. Drinking a particular type of tea or taking supplements will not affect its functioning.

Leading a healthful lifestyle is the best way to support the immune system. Doing this may include:

  • eating a nutritious diet
  • exercising regularly
  • avoiding triggers of stress where possible
  • getting enough sleep
  • avoiding tobacco
  • abstaining from alcohol or drinking it in moderation
  • achieving and maintaining a healthy weight

Anxiety disorders are a group of common mental health conditions that affect about 19.1 percent of adults in the United States each year. There are several types of anxiety disorder, but they share the same primary symptom of a state of excessive worry or panic.

Anxiety disorders can affect the body in several ways that may contribute to recurring sickness. For example, anxiety disorders can cause:

  • fatigue
  • muscle tension
  • difficulty concentrating
  • sweating
  • heart palpitations, or rapid heartbeat
  • trembling
  • shortness of breath
  • irritability

Over extended periods, an anxiety disorder can also lead to physical health complications. For example, people with anxiety disorders have a higher risk of heart disease and early death.

Many different treatments are available for anxiety disorders. Talking therapies, such as CBT, are one option. Antidepressants, beta-blockers, or other medications can help with the symptoms of anxiety too.

Research also shows that engaging in mindfulness meditation or physical activity can benefit people with anxiety disorders.

Frequently becoming sick can have a range of causes, including stress and lack of sleep. Lifestyle changes may be enough to prevent these causes in some cases.

If a person keeps getting sick due to an underlying condition, such as an autoimmune disease or anxiety disorder, treating the condition may reduce the frequency of illness.

Leading a healthful lifestyle that includes exercise, stress management, adequate sleep, and proper nutrition can help prevent a range of factors that cause people to keep getting sick.
