The COVID-19 pandemic may be over, but our immune systems are still feeling the impact. After years of battling constant viral threats, from COVID-19 to seasonal flu and other infections, our body’s defense system is exhausted. Many people continue to experience lingering inflammation, frequent illnesses, and slower recovery times. This extended state of immune stress has compromised us further to chronic illness, including autoimmune diseases and even neurodegenerative diseases such as Parkinson's. So why is our immune system still in trouble? And how do we give it its power back? Understanding immune exhaustion is the beginning of rebuilding our body's natural immunity.

A weakened immune system makes people more susceptible to disease, mental illnesses, and even sleep disorders. Now, new research indicates that immune system depletion may play an important role in the onset of Parkinson's disease, a degenerative neurologic disorder that compromises movement and cognition.

Role of Inflammation in Parkinson's Disease

Dysfunctional immune response is a leading cause of long-standing inflammation within the body, that has been found to contribute towards a multitude of conditions, including cardiovascular conditions, diabetes, depression, and neurodegenerative diseases such as Alzheimer's.

As people age, their immune system naturally becomes less effective. This deterioration, referred to as immune exhaustion, may be a key contributor to the onset and progression of Parkinson’s disease. Rebecca Wallings, a Parkinson’s Foundation Launch Award grant recipient and senior postdoctoral fellow at the University of Florida, believes that an accumulation of exhausted immune cells could be driving neurodegeneration in Parkinson’s patients.

How a Tired Immune System Might Affect Parkinson's?

Parkinson's disease is most commonly linked with the degeneration and loss of dopaminergic neurons—motor nerve cells that produce dopamine, an essential neurotransmitter for movement. While researchers have long suspected inflammation is involved in this neurodegeneration, the mechanisms are not yet well understood.

Wallings' study is on immune cell exhaustion, a process by which aging immune cells fail to control immune responses effectively. Her research indicates that instead of dampening inflammation in Parkinson's patients, attempts should be made to rejuvenate the immune system to regain its functionality.

Energy Deficiency in Immune Cells

One of the major findings of Wallings' work is the function of mitochondrial impairment in immune cell exhaustion. Mitochondria are commonly called the powerhouses of cells, as they are vital for generating energy. As mitochondria age and become inefficient, immune cells fail to function well, potentially accelerating neurodegeneration in Parkinson's disease.

Wallings has found that mutations in the LRRK2 gene, a recognized genetic risk factor for Parkinson's disease, are linked with defective mitochondrial function and immune cell exhaustion. Her current work includes testing various therapeutic approaches to restore mitochondrial function in immune cells with the potential to enhance the immune system and potentially prevent or treat Parkinson's disease.

Will Rejuvenating the Immune System Help in Treatment?

For decades, the standard practice in treating Parkinson's has been to suppress brain inflammation. Yet Wallings' work indicates that instead of slowing down immune responses, restoring the immune system could be a more successful strategy. By addressing mitochondrial impairment and immune resilience, researchers can potentially reverse or slow down Parkinson's disease.

Wallings is now looking into how to rejuvenate immune cells by fixing mitochondria. She studies immune cells from patients with Parkinson's as well as from healthy subjects and performs experiments on animal models to determine if rejuvenation of the immune system could result in improved disease outcomes.

Lifestyle Factors That May Affect Parkinson's Risk

While there is no cure for Parkinson's disease, some lifestyle adjustments may decrease the chances of developing the illness. Since neurodegenerative diseases are associated with chronic inflammation and immune dysfunction, developing habits that enhance immune function might prove helpful.

Diet: There is evidence to suggest that eating in accordance with the Mediterranean or MIND diets, both high in antioxidants, healthy fats, and anti-inflammatory foods, can encourage brain wellness and reduce Parkinson's risk.

Avoiding Dangerous Substances: Restricting alcohol and nicotine use can maintain a robust immune system and suppress inflammation.

Reducing Stress: Chronic stress weakens immune function, so methods such as meditation, exercise, and sufficient sleep can lead to improved overall well-being.

Women, are you planning a pregnancy? Do you wish to fulfil the dream of motherhood? Did you know it is possible to improve embryo quality for successful conception? Do not worry—we have you covered. This article highlights how appropriate lifestyle choices, proper nutrition, and timely medical care can play a key role in improving embryo quality. Hence, it is essential to follow the guidelines given below.

Why is infertility a common concern now?

Dr Jyoti Gupta, Senior IVF Consultant, Motherhood Hospitals, Gurgaon, in an interview with Health and Me, shared some simple tips for couples. These can go a long way in improving embryo quality and may even enhance the chances of conception.

Currently, many couples are battling infertility and undergoing in vitro fertilisation (IVF). Embryo quality is one of the most important factors influencing the success of pregnancy, especially in couples who have opted for IVF. Good-quality embryos have a higher likelihood of implantation, resulting in a healthy and successful pregnancy. Even though some factors, such as age and genetics, cannot be changed, there are several ways to support and improve embryo quality both naturally and medically.

Embryo quality is based on the health of both the egg and sperm. As women age, egg quality tends to decline, which can affect embryo development. Moreover, sperm health also plays a vital role. Lifestyle, diet, and stress can negatively impact egg and sperm quality and, in turn, embryo quality.

Tips to improve embryo quality

It is necessary for couples to focus on their diet to improve embryo quality. Including foods rich in antioxidants, such as fresh fruits, vegetables, nuts, and seeds, can help protect eggs and sperm from damage. Nutrients such as folic acid, omega-3 fatty acids, vitamin D, and iron are important for reproductive health. It is also important to stay well hydrated and cut down on processed foods, excess sugar, and caffeine. Seek expert guidance when it comes to diet, and avoid following extreme diets independently, as mindful eating is essential.

1. Maintaining a healthy weight is also important. Both underweight and overweight individuals may experience hormonal imbalances, which can affect fertility. Ensure you exercise regularly—walking, yoga, or light workouts can help improve blood flow and support reproductive health without placing excessive stress on the body.
2. Quitting smoking, alcohol, and illicit drug use, and avoiding exposure to environmental toxins can also improve egg and sperm quality.
3. Managing stress through relaxation techniques such as meditation, deep breathing, or counselling can help regulate hormones and improve overall well-being.

Consulting a doctor to identify underlying issues, such as hormonal imbalances, thyroid disorders, or conditions like PCOS or endometriosis, is essential. Following personalised treatment plans, including supplements and medications as prescribed by a doctor, can help enhance embryo quality.

In today’s fast-paced digital world, convenience often comes at the cost of physical activity. Long working hours at desks, increased screen time, and reduced outdoor movement have led to a dramatic rise in sedentary lifestyles. While the immediate effects, such as weight gain and fatigue, are widely recognised, the long-term impact on bone and joint health is often underestimated.

Medical experts specialising in orthopaedics in Delhi NCR are increasingly observing a surge in younger patients presenting with joint pain, stiffness, and early signs of musculoskeletal disorders. What was once considered age-related is now becoming common among individuals in their 20s and 30s, largely due to inactivity.

Understanding a Sedentary Lifestyle

A sedentary lifestyle refers to a pattern of behaviour that involves prolonged periods of sitting or inactivity with minimal physical movement. Activities such as working on a computer, watching television, or using mobile devices for extended durations contribute to this condition.

When the body remains inactive for long periods, it leads to reduced muscle engagement, poor circulation, and decreased joint mobility. Over time, this inactivity begins to affect the structural integrity of bones and joints.

Impact on Bone Health

Bone health is highly dependent on regular movement and physical activity to maintain strength and density. A sedentary lifestyle can gradually weaken bones, increasing the risk of fractures and long-term skeletal issues.

1. Reduced Bone Density

Bones require regular stress and movement to maintain their strength. Physical activities such as walking, running, or resistance training stimulate bone formation and improve density.

A sedentary lifestyle, however, deprives bones of this essential stimulation, leading to reduced bone mineral density. Over time, this increases the risk of conditions such as osteoporosis, even at a relatively young age.

2. Increased Risk of Fractures

Weak bones are more prone to fractures, even with minor injuries. Individuals who lead inactive lives often have lower bone strength, making them vulnerable to accidental falls or trauma.

Impact on Joint Health

Joint health depends on regular movement to maintain lubrication and flexibility. A sedentary lifestyle can lead to stiffness, reduced mobility, and a higher risk of joint degeneration over time.

1. Early Joint Degeneration

Joints rely on movement to stay lubricated and functional. Synovial fluid, which reduces friction between joint surfaces, is produced more effectively when joints are in motion.

In a sedentary lifestyle, lack of movement leads to stiffness and reduced lubrication, accelerating joint degeneration. This can result in early onset of osteoarthritis, particularly in weight-bearing joints such as the knees and hips.

2. Muscle Weakness and Joint Instability

Muscles play a crucial role in supporting and stabilising joints. When physical activity is limited, muscles weaken, placing additional stress on joints.

This imbalance increases the likelihood of joint injuries, ligament strain, and chronic pain.

Obesity and its Impact on Bones and Joints

One of the most significant consequences of a sedentary lifestyle is weight gain. Obesity places excessive stress on bones and joints, particularly in the lower body.

1. Increased Load on Joints

Every extra kilogram of body weight adds significant pressure on the knees and hips. Over time, this leads to cartilage wear and tear, increasing the risk of osteoarthritis.

2. Inflammation and Pain

Obesity is associated with chronic low-grade inflammation, which can worsen joint pain and stiffness. This further reduces mobility, creating a vicious cycle of inactivity and worsening symptoms.

Rise of Musculoskeletal Disorders

Healthcare providers specialising in orthopaedics in Delhi NCR report a growing number of cases related to sedentary habits, including:

Chronic back pain

Neck stiffness and cervical spondylosis

Frozen shoulder

Repetitive strain injuries

Carpal tunnel syndrome

These conditions are often linked to poor posture, prolonged sitting, and lack of ergonomic awareness.

Role of Poor Posture

Posture plays a critical role in maintaining musculoskeletal health. Sitting for long hours with improper alignment, such as slouching or leaning forward, places undue stress on the spine and surrounding muscles.

Common Postural Issues

Forward head posture

Rounded shoulders

Lower back strain

Over time, these habits can lead to chronic pain and structural imbalances, requiring medical intervention.

Preventive Measures for Better Bone and Joint Health

While the effects of a sedentary lifestyle can be serious, they are largely preventable with conscious effort and lifestyle modifications.

1. Regular Physical Activity

Engaging in regular exercise is one of the most effective ways to maintain bone and joint health.

Recommended activities include:

Walking or jogging for at least 30 minutes daily

Strength training to build muscle support

Flexibility exercises, such as yoga or stretching

Low-impact activities like swimming or cycling

These activities help improve bone density, enhance joint mobility, and strengthen muscles.

2. Maintain a Healthy Weight

Weight management is crucial in reducing stress on joints. A balanced diet combined with regular exercise helps prevent obesity and its associated complications.

3. Posture Correction

Being mindful of posture can significantly reduce the risk of musculoskeletal problems.

Tips for better posture:

Keep your back straight and shoulders relaxed

Ensure your screen is at eye level

Avoid slouching while sitting or standing

Use lumbar support for the lower back

4. Ergonomic Work Setup

With the rise of remote work, having an ergonomic workstation is essential.

Key ergonomic practices include:

Adjustable chair with proper back support

Desk height aligned with elbow level

Feet flat on the floor or on a footrest

Keyboard and mouse positioned comfortably

Taking short breaks every 30–60 minutes to stretch and move is equally important.

5. Stay Active Throughout the Day

Even small changes can make a big difference:

Use stairs instead of elevators

Take short walking breaks

Stand or walk while taking phone calls

Incorporate movement into daily routines

6. Early Medical Intervention

Ignoring early signs of discomfort can lead to more serious conditions. Symptoms such as persistent pain, stiffness, or reduced mobility should not be overlooked.

Consulting specialists in Orthopaedics in Delhi NCR at an early stage can help diagnose underlying issues and prevent further deterioration. Early intervention often reduces the need for invasive treatments.

Conclusion

A sedentary lifestyle is one of the most significant yet preventable risk factors affecting bone and joint health today. From reduced bone density and early joint degeneration to obesity-related stress and musculoskeletal disorders, the consequences are far-reaching.

The increasing demand for Orthopaedics in Delhi NCR reflects a growing need to address these issues proactively. By incorporating regular physical activity, maintaining proper posture, adopting ergonomic practices, and seeking timely medical advice, individuals can protect their musculoskeletal health and improve overall well-being.

Many people do not realise just how closely mental health and liver health are connected—especially when alcohol becomes a go-to coping strategy for stress, anxiety, or emotional overwhelm. What may seem like temporary relief can quietly evolve into a pattern that affects both the mind and the body in significant ways. Dhara Ghuntla, Psychologist affiliated with Sujay Hospital, 7 Hills Hospital, Criticare Hospital, in an interaction with Health and Me, spoke about the impact of stress, alcohol use and emotional eating on the liver.

In today’s fast-paced, high-pressure lifestyle, it is common for individuals to turn to alcohol to unwind or escape difficult emotions. In the short term, alcohol can create a sense of relaxation or numbness. However, over time, this reliance can shift into a habitual coping mechanism and eventually into dependence. While the psychological impact is often discussed, the physical consequences—particularly on the liver—are just as important.

The liver plays a critical role in detoxifying the body. Regular alcohol consumption places it under constant strain, impairing its ability to function effectively. Over time, this can lead to conditions such as fatty liver, inflammation, and even long-term liver damage. What makes this especially concerning is that early-stage liver issues often present with little to no obvious symptoms, allowing damage to progress unnoticed.

At the same time, liver health has a direct influence on mental well-being. When the liver is compromised, it can affect energy levels, mood regulation, and cognitive function. People may experience increased fatigue, irritability, anxiety, low mood, or emotional instability. This happens because the liver plays an indirect but essential role in brain health through metabolism and toxin clearance.

The Vicious Cycle

This creates a self-perpetuating loop. A person feeling stressed, low, or anxious may turn to alcohol for relief. While it may help temporarily, it simultaneously places stress on the liver. As liver function declines, mental health symptoms—such as fatigue, irritability, anxiety, or low mood—can worsen. This often leads the individual to consume more alcohol, reinforcing the cycle.

Adding another layer, many individuals who rely on alcohol are often dealing with underlying issues such as depression, anxiety, sleep disturbances, or chronic life stressors. Alcohol is frequently used as a form of self-medication. However, instead of addressing these root concerns, it masks them temporarily while deepening both psychological and physical harm. Over time, this pattern increases dependency and makes recovery more complex.

The Gut–Liver–Brain Connection

Liver health is also closely tied to gut function and brain health. When the liver is under stress, digestion can be affected, nutrient absorption may decline, and energy levels can drop. This interconnected system—the gut, liver, and brain—plays a key role in emotional regulation and overall well-being. Disruptions in one area can ripple across the others, influencing how a person thinks, feels, and functions daily.

Breaking the Pattern

Recognising this connection is the first step towards change. Instead of turning to alcohol, healthier coping strategies can help regulate stress and support both mental and physical health. Practices such as yoga, meditation, regular exercise, journalling, and maintaining a balanced diet can significantly improve resilience and emotional stability.

Prioritising mental well-being, addressing underlying psychological concerns, and protecting liver health are not separate goals—they are deeply interconnected. Seeking timely support, whether through therapy, lifestyle changes, or medical guidance, can help break the cycle.

Reducing or eliminating alcohol use is not just about avoiding physical harm; it is about creating space to heal the underlying causes of stress and emotional distress. Supporting the liver, nurturing the gut, and caring for mental health together can lead to more sustainable and meaningful well-being.
