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.
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.
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.
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.
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.
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.

High blood pressure (BP) has become a public health problem that is driving cardiovascular diseases like heart attacks and strokes globally. While medications are important to keep hypertension under control, lifestyle changes and healthy practices are also crucial.
Several global health guidelines recommend regular physical activity, but adhering to exercise programs daily becomes a challenge for many people. But in the overtly busy schedules, sparing 10 minutes for an exercise regimen can be easier than travelling to the gym.
A large randomized clinical trial, published in the Journal of the American College of Cardiology (JACC), has proved that a traditional Chinese mind-body practice — baduanjin — may help lower blood pressure, that too, without any equipment.
Baduanjin is a slow, structured movement, focused on deep breathing and meditation.
Importantly, the clinical trial proved that the ancient Chinese technique could lower BP as effectively as brisk walking.
In people practicing baduanjin, BP reductions were seen after three months and were sustained for one year.
"Given its simplicity, safety, and ease with which one can maintain long-term adherence, baduanjin can be implemented as an effective, accessible, and scalable lifestyle intervention for individuals trying to reduce their blood pressure," said Jing Li, Director, National Center for Cardiovascular Diseases in Beijing, China.
Baduanjin is a standardized eight-movement sequence that integrates aerobic, isometric, flexibility, and mind-body components.
It has been in practice for centuries and commonly performed in community settings across China. The routine typically takes 10–15 minutes and requires no equipment and only minimal initial instruction.
Because it is low- to moderate-intensity, it is considered safe and accessible for many adults.

A team of Chinese researchers led the first large, multicenter randomized trial to look at the impact of baduanjin on blood pressure.
They followed 216 participants, aged 40 years or older, across seven communities to determine changes in 24-hour systolic BP from baseline to 12 and 52 weeks.
Compared to people indulging in self-directed exercise, practicing baduanjin five days a week reduced
Notably, the benefits were sustained even without ongoing monitoring, a key challenge for many lifestyle interventions that struggle to maintain long-term adherence outside structured programs.
"Baduanjin has been practiced in China for over 800 years, and this study demonstrates how ancient, accessible, low-cost
approaches can be validated through high-quality randomized research," said Harlan M. Krumholz, Editor-in-Chief of JACC and the Harold H. Hines, Jr Professor at the Yale School of Medicine.
"The blood pressure effect size is similar to that seen in landmark drug trials, but achieved without medication, cost, or side effects. This makes it highly scalable for community-based prevention, including in resource-limited settings," they added.

Are you a working professional? Have you been diagnosed with endometriosis? Worried about how this condition can impact your career? Well, don’t panic! We give you vital tips to manage the symptoms of endometriosis without compromising your professional aspirations. Dr. Kanika Gera Thakral, Consultant – Obstetrics & Gynaecology, Motherhood Hospitals, Greater Noida, spoke about the effects of endometriosis on working women and what women can do to not let the pain take a toll on their work life.
Endometriosis happens when tissue similar to the lining of the uterus grows outside the uterus. These tissues commonly develop on the ovaries, fallopian tubes, or the pelvic lining. Endometriosis affects many women and can impact their daily lives, including their ability to work comfortably. Many women continue their professional responsibilities despite experiencing severe discomfort, fatigue, and pain.
Raising awareness about the condition and encouraging supportive workplaces can help women manage both their health and career more effectively. Since it is a progressive disorder, timely intervention remains key to managing it. In many cases, women live with symptoms for several years before receiving the correct diagnosis, which can delay treatment and affect their quality of life.

The workplace challenge
Many working women who are diagnosed with endometriosis tend to experience symptoms such as pelvic pain, cramps, fatigue, nausea, and heavy menstrual cycles. These symptoms can make it difficult to maintain productivity at work, especially during flare-ups. Hence, women will be unable to concentrate on work or finish the tasks. Some may miss deadlines and meetings due to the painful symptoms. Women will have to skip going to work when the symptoms are intense and will have to rest at home. So, women living with endometriosis may face interruptions in their career growth and reduced working hours. But don’t worry, it is possible to manage this condition and give your best at work.

Strategies for managing work and endometriosis
It is necessary for women with endometriosis to go for regular check-ups and follow-ups with the doctor. Women can continue to pursue their professional goals by adopting practical strategies to manage the condition. Open communication with employers when it comes to flexible schedules can help overcome stress and anxiety. Women should have access to remote working to avoid unnecessary travel due to pain.
The work-from-home option can be given to the women when needed by them. Planning demanding tasks during times of higher energy and maintaining a balanced daily routine can also improve productivity at work. Women should make sure to keep essential medications, a heating pad, or comfort aids at their desk to be able to relieve sudden discomfort. Likewise, using ergonomic seating or maintaining good posture while working may reduce pelvic and even back discomfort. Women should also connect to support groups that help to provide emotional reassurance and useful coping strategies that include yoga and meditation.
Lifestyle habits also play an important role. Regular physical activity, adequate sleep, stress-management techniques such as yoga or meditation, and following an anti-inflammatory diet rich in fruits, vegetables, whole grains, and healthy fats may help reduce flare-ups.

Treatment is particularly based on the severity of symptoms. Women will be advised lifestyle modifications such as regular exercise, stress management, and an anti-inflammatory diet. Non-steroidal anti-inflammatory drugs may help reduce discomfort. Hormonal therapies may also be used to control symptoms. Some women will be advised to undergo laparoscopy to remove endometriotic cysts. Minimally invasive surgery can help remove lesions and restore pelvic anatomy, which may also improve fertility in some cases. In advanced cases, surgery can be recommended to women.
With timely care and supportive workplaces, women can pursue their ambitions without letting endometriosis interfere with their careers.

Four years after suffering from a rare neurological condition known as Stiff-Person Syndrome, Céline Dion, known for power ballads like My Heart Will Go On and Because You Loved Me, has announced her return to the stage.
The incurable condition had affected her singing voice and even her ability to walk.
In a message on her Instagram page, the singer announced plans to play a 10-night residency at the 40,000-capacity Paris La Défense Arena in September and October.
Calling her comeback "the best gift of my life", 58-year-old Dion said: "I'm doing great, managing my health, feeling good. I'm singing again, even doing a little bit of dancing.
"I'm so ready to do this. I'm feeling good, I'm strong, I'm feeling excited, obviously, [and] of course, a little nervous," she said, while thanking her fans for the “prayers and support, kindness and love”.
Stiff-Person Syndrome is a neurological disease caused by the signals from the nerves to the muscles not working properly. It affects an estimated 8,000 people worldwide.
It is also an autoimmune is a neurological disease caused by the signals from the nerves to the muscles not working properly. It affects an estimated 8,000 people worldwide.
It is also an autoimmune condition, that is linked to diseases such as type 1 diabetes, thyroiditis, vitiligo, and pernicious anemia.
For some, it can be debilitating. SPS is progressive, meaning it gets worse over time. There is no known cure.
Common symptoms may include:
The condition is also more common among women than men, and affects people between the ages of 20 and 60.
While there is no known cure for SPS, current treatments such as intravenous immunoglobulin (IVIg) can help manage the symptoms.
Dion announced her diagnosed with Stiff Person Syndrome (SPS) in December 2022 in an emotional Instagram video. The condition had affected "every aspect of my daily life", she told her fans.
The best-selling artists of all time began noticing her symptoms, such as feeling "a little spasm" while performing on stage. She found her “voice was struggling", BBC reported.

Even though she experimented with her singing to ease the stress on her vocal cords, her condition worsened. She also began facing difficulties while walking.
"It's like somebody is strangling you. It's like somebody is pushing your larynx [or] pharynx," she told NBC News.
Determined to get back on her feet and sing, worked "all my body and soul, from head to toe, with a medical team", French Vogue magazine reported.
"Five days a week, I undergo athletic, physical, and vocal therapy. I work on my toes, my knees, my calves, my fingers, my singing, my voice."
The intense workouts enabled her to make a comeback at the 2024 Paris Olympics, singing Edith Piaf's classic Hymne à l'Amour from the Eiffel Tower.
