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.

The journey of a breast cancer patient does not end when their treatment comes to a conclusion. There is always a risk of recurrence, which makes regular follow-ups and adherence to treatment important.

At the Times Network India Health Summit and Awards 2026 in New Delhi, a panel formed by Dr Priya Parmar, Chief Operating Officer, Indian Cancer Society, Delhi, Dr. Jyoti Wadhwa - Principal Lead of Medical and Precision Oncology, Apollo Athena Women’s Cancer Centres, New Delhi and Apollo Hospital, Gurgaon, Dr. Meenu Walia, Chairman Medical Oncology, Max Healthcare, Dr Pankaj Goyal, Sr Consultant and Unit Head, Medical Oncology, RGCI, and Vaishali Iyer, Country Head, Communications, Patient Advocacy and CSR, Novartis in India, discussed the big picture after breast cancer treatment.

During a panel discussion titled “Take Charge Together: Shaping a Future of Greater Breast Cancer Awareness and Better Outcomes,” experts highlighted the physical, emotional, social and financial challenges that women may continue to face after treatment among many more.

What Comes After Breast Cancer Treatment?

For many women, the period after breast cancer can involve more than medical monitoring. They may face fatigue, menopausal symptoms and changes in body image after undergoing a major physical change, while concerns about intimacy, fertility and relationships can affect emotional and mental well-being.

Dr. Priya Parmar highlighted how losing a breast or hair can affect a woman's sense of identity and femininity. Some survivors also face social stigma related to marriage and fertility, while sexual health and relationship concerns may remain difficult to discuss.

The burden can be greater for women who lack family support or have limited financial resources. These circumstances may affect not only emotional recovery but also their ability to attend follow-up appointments and continue treatment.

The financial strain can become particularly difficult if cancer returns and further investigations or treatment are required.

Dr. Meenu Walia said that treatment for advanced disease can add to the economic burden faced by patients and their families.

Risk Of Recurrence

The risk of breast cancer recurrence is not the same for every patient. It depends on the cancer's stage and subtype, tumour grade, lymph node involvement, response to treatment and whether treatment is timely.

Dr. Jyoti Wadhwa explained that different breast cancer subtypes can follow different recurrence patterns.

Triple-negative breast cancer tends to recur earlier, often within the first two to three years after treatment. Hormone receptor-positive, HER2-negative breast cancer, however, can return even 10 to 20 years later.

She also said that patients who achieve a pathological complete response after treatment given before surgery may have a lower risk of recurrence than those with residual disease.

However, a lower estimated risk does not mean the risk is eliminated. Continued monitoring is important even for patients who have responded well to treatment.

Feeling Better Is Not A Reason To Skip Follow-Ups

One concern raised by the experts was that some patients stop taking prescribed oral hormone therapy or miss appointments after their symptoms improve.

“Your first attempt at treatment is always your best attempt,” Dr. Walia said, underlining the importance of appropriate diagnosis and treatment from the outset.

Follow-up care helps doctors monitor a patient's recovery, assess treatment-related effects and make decisions based on individual clinical circumstances. The appropriate schedule and any further treatment depend on the patient's diagnosis, risk profile and medical history.

Experts also cautioned against allowing the possibility of recurrence to dominate a survivor's life. Understanding individual risk should help patients make informed decisions, rather than leave them in constant fear that cancer will return.

Post-Treatment Care Needs More Than Medical Monitoring

The long-term effects of breast cancer also have implications beyond the individual patient. Vaishali Iyer, Country Head of Communications, Patient Advocacy and CSR at Novartis in India, highlighted an estimated 140 million productive hours lost due to breast cancer care, drawing attention to its wider economic impact.

Dr. Wadhwa emphasised the need to address treatment-related concerns, including menopausal symptoms and bone health, which may require attention even after primary cancer treatment has ended.

Dr. Pankaj Goyal, Senior Consultant and Unit Head of Medical Oncology at RGCI, stressed that doctors must build trust with patients and explain recurrence risks without causing unnecessary alarm. Discussions about care should also account for patients' personal circumstances and financial constraints.

The panel discussion, titled “Take Charge Together: Shaping a Future of Greater Breast Cancer Awareness and Better Outcomes,” took place at the Times Network India Health Summit and Awards 2026.

Padma Bhushan Dr Shiv Kumar Sarin, leading hepatologist, gastroenterologist, and medical educator who also serves as the Senior Professor, Chancellor, and Director of the Institute of Liver and Biliary Sciences (ILBS), recently spoke about the dos and don’ts to maintain a healthy liver at the Times Health Summit 2026.

Held under the theme “The Blueprint for a Future-Ready Healthcare Ecosystem – Innovation. Access. Self-Reliance,” the summit brought together healthcare professionals and industry stakeholders to discuss innovation, access to treatment and policy approaches shaping India's healthcare sector.

Should You Drink Hot Water In The Morning For Bowel Movement?

The doctor addressed the daily morning ritual of drinking hot water in the morning, which a lot of people follow to release bowels.

Dr Sarin said, “Don't use hot water or anything for that matter to make you go to the toilet because it is the connection between the brain and the bowel that is very important.

He also spoke about opting for other drinks like coconut water or lemon water with honey. He said that lemon can help improve iron absorption in your body.

He added, “As per coconut water is concerned, it has potassium which is very good for your bowel health but it should still not be an everyday thing. For nimbu and honey, you should remember that honey has fructose. So if you are consuming honey, you also need to churn that out."

Ideal Time for Breakfast

Many of us do not know what is the right time for breakfast. It is especially important as eating after fasting for eight to ten hours affects your energy and metabolic health throughout the day.

Dr Sarin said, "It's after sunrise. Minimum 12 hours after the last food that you have eaten. Ussay pehle galti nahi kariyega khaanay ki. Let the stomach, and the bacteria and the intestine recover."

He also spoke about whether you should have fruits for breakfast. "Breakfast should be fruits. And, low calories fruits. Avoid carbs."

How Coffee Affects The Liver

There is a lot of information as well as misinformation about coffee consumption and liver health. Dr S K Sarin spoke in its favour and said that it could prevent a lot of liver conditions.

He said, "It does many things. it clears several toxic things including fat, clears the flow of bile, good enzyme inducer, prevents fibrosis of the liver and can decrease cirrhosis and also the development of liver cancer."

He also warned ignoring healthy dietary habits and simply relying on coffee is also not ideal. He added, "Coffee is not medicine, it is something which can help you prevent and not treat."

Is Your Lunch Completely Healthy?

Dr Sarin also warned against eating more amount carbohydrates than the recommended limit. He explained how sitting next to an obese person can make you feel physically lethargic as their breath may emit endogenous alcohol.

When you eat a carbohydrate-heavy meal, your digestive system breaks down carbohydrates into sugars. Certain microorganisms in the gut, including yeasts and some bacteria, can ferment these sugars and produce small amounts of ethanol, or alcohol. This is known as endogenous alcohol production.

Dr Sarin recommends eating low-carb meals for lunch like sprouts, vegetables, yoghurt, buttermilk or low-sugar fruits.

Late-Night Eating Is A Red Flag

Dr Sarin recommends having dinner before sunset. He also said that having late-night dinners could disrupt your sleep.

He added, "Obesity during youth increases the risk of heart disease later in life. After the age of 40, eating one meal a day may have health implications. The total daily calorie intake should not exceed 300–400. Avoid eating late at night. Eating late can also affect your insulin resistance."

Yearly Screening To Keep Liver Health In Check

Dr Sarin also said that thin people can also have unhealthy fat that may cause fatty liver. He recommended yearly screens to keep liver health in check.

He said, "Even thin people can have excess body fat and low muscle mass, which may affect their health. Being thin does not necessarily mean being healthy. Maintaining good muscle mass is important."
