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.

Feeling anxious, unable to perform well, and feeling burnt out at the workplace is a common problem facing employees slogging for over nine hours every day. But now, a study suggests that taking short vacations every two months can help reduce stress accumulation.
In a 2025 research paper titled “Maximizing Recovery: The Superiority of Frequent Vacations”, Selvaraj Giridharan from the Oncology Department at Tawam Hospital in Abu Dhabi suggests that taking short breaks can help improve mental well-being and boost work performance.
The study argued that instead of a long annual vacation, frequent short breaks are often more effective and help people mentally detach from work. This also helps them recover from burnout faster.
Researchers also found that the positive effects of vacations usually fade within a few weeks after returning to work, making regular breaks important for maintaining emotional balance and productivity.
"We emphasize how regular vacations facilitate recovery and enhance well-being, thereby reducing stress and improving performance. We advocate the integration of frequent breaks into workplace culture through practical strategies for both individuals and organizations," wrote study author Selvaraj Giridharan.

Amid discussions around 70-hour work weeks advocated by industrialists like Narayana Murthy, the study comes as a breather.
The researchers, including experts from the National Health Service, stressed that sustained work-related stress causes significant psychobiological strain. This depletes physiological and psychological resources, manifesting as elevated cortisol levels, cognitive fatigue, and emotional exhaustion.
Without periodic recovery, this strain accumulates, increasing the risk of burnout, reduced productivity, and adverse health outcomes. India has seen several recent cases where workplace stress has affected people’s mental health, with some collapsing at work while others resorted to suicide.

The paper cited a meta-analysis of 22 studies that showed that vacations provide substantial psychological, physiological, and cognitive benefits.
It noted post-vacation reductions in exhaustion, improvements in mood, and increases in life satisfaction among employees.
The findings were found consistent with several studies which identified physiological improvements, including reduced cortisol levels, enhanced heart rate variability, and better sleep quality. These outcomes reflect mitigation of the physiological burden of chronic stress and position vacations as vital health interventions.
The researcher stated that vacations are essential for mitigating the psychobiological impacts of contemporary work and providing psychological, physiological, and cognitive advantages.
Although the duration of vacations is significant, frequent and shorter vacations are more effective in maintaining well-being through regular recovery, they said.
"This evidence-based perspective, rooted in effort-recovery theory, advocates strategic vacation planning by organisations and policymakers to prioritise workforce health. Societies should promote vacation policies that emphasise frequency in order to enhance employee well-being and performance,” the paper said.

In India, poor reproductive health awareness remains one of the most overlooked gaps in women’s healthcare. Many women continue to ignore gynecological symptoms, assuming them to be routine, temporary, or too embarrassing to discuss.
Persistent vaginal infections, irregular bleeding, untreated hormonal disorders, chronic pelvic pain, or recurring inflammation are often dismissed until they become severe. In some cases, these untreated or undiagnosed conditions can silently contribute to long-term health risks, including certain cancers.
Today, many women have heard of conditions like PCOS, endometriosis, or fibroids. But awareness is often incomplete. Women may know the name of a condition, yet not know its warning signs, complications, or when medical attention is necessary.
For example, prolonged hormonal imbalance, obesity, irregular periods, and chronic inflammation may increase the risk of certain gynecological cancers over time. Similarly, lack of awareness about HPV, cervical screening, and vaccination continues to delay prevention and early diagnosis of cervical cancer.
Fertility awareness is another important gap. Many women are not familiar with their menstrual cycle, ovulation pattern, or normal reproductive changes. When women do not know what is normal for their own body, it becomes harder to recognize when something is wrong.
Social media has added another layer to this problem. While it has improved access to health information, it has also created confusion. Quick tips, unverified remedies, and incomplete advice can delay proper diagnosis and treatment.
Reproductive literacy is not just about knowing symptoms. It means understanding one’s body, menstrual cycle, sexual health, fertility, contraception, screening options, vaccination, and access to safe healthcare.
Unfortunately, stigma around sexual and reproductive health still prevents many women from seeking timely care. Symptoms such as abnormal discharge, bleeding after intercourse, pelvic pain, or irregular bleeding are often hidden out of fear, shame, or hesitation.
This delay is especially dangerous in cancers such as cervical, uterine, ovarian, and vaginal cancers, where early evaluation can make a major difference.

Actress Lisa Ray was diagnosed with Multiple Myeloma, an incurable but treatable blood cancer, in 2009. She successfully went into remission but experienced a cancer relapse shortly after her wedding in 2012.
During her journey to recovery, she became a prominent advocate for cancer awareness and research. However, it was during this period, at the age of 37, that she also suffered chemo-induced menopause — a topic she brushed aside, not wanting to bring it up out of shame and fear, reflecting the taboo society still associates with the natural end of a woman’s reproductive phase.
In an interaction with HealthandMe, the Oscar-nominated film Water (2005) actress opened up about her experience with chemo-induced menopause.
“I went into chemo-induced menopause at 37. I was given no support. I was completely lost. And even for a subsequent decade after that, I couldn’t find any answers. I didn’t know how to take care of myself. I didn’t know I had options,” she said.
The actress shared that she normalized many of her symptoms and avoided speaking openly about menopause despite being candid about cancer.
“I was so vocal about cancer. I’m actually somebody who prefers to be quite truthful about what I’m going through. I don’t really like to hide things. I’m not secretive by nature. And yet, I carried this burning secret inside me for so many years,” she said.
“When I was being lauded as someone who was breaking through the silence of cancer, I was carrying the silent secret inside me. I couldn’t understand why for many years. And I realized today, I was carrying shame.”
She noted that menopause continues to remain a deeply misunderstood and under-discussed subject, despite affecting all women.
Lisa said conversations around menopause were absent even within families.
“My mother never talked to me about menopause. Of course, we discussed my period when I got it, but menopause was simply like a black box,” she said.
The actress recalled that discussions around perimenopause and menopause only began when many of her close friends started experiencing symptoms themselves.
Calling the silence around menopause “astonishing” and “extremely unjust,” Lisa said women’s hormonal health continues to be severely underfunded and misunderstood globally.
“Menopause impacts all women. Yet it’s treated like a dark secret,” she told HealthandMe.
Lisa added that once she began researching the issue, she became increasingly frustrated by the lack of awareness and medical attention surrounding menopause and hormonal health.
Menopause Not Getting Enough Attention
The actress said that after moving to Dubai, she began openly discussing menopause on social media, despite initially worrying about public reaction.
“Sometimes in social settings, women would almost shut down or turn away and say, ‘Don’t talk about that.’ But when I put it on social media, maybe it permitted a lot of other women to also find a place to have a conversation or a community,” she said.
To bring about change where women can speak freely about the topic and seek treatment early, Lisa has co-founded NuHer, a science-backed health clinic and platform dedicated to midlife care for women. It is designed to support perimenopause and menopause through personalized medical treatments, clinical psychology, and nutritional guidance.
When asked why she chose to focus on menopause and women’s hormonal health, the Four More Shots Please! actress stated, “Menopause is simply not getting the attention that it needs. Women are struggling to get the care that they need and understand their options.”
Lisa explained that while awareness around cancer has steadily improved in India since her multiple myeloma diagnosis in 2009, menopause remains “the next taboo or frontier.”
According to Lisa, NuHer aims to create a safe, science-backed space where women can access support without judgment or dismissal.
“We need a place where women can be heard, where they’re not dismissed, where they’re not gaslit, where they receive all the right science and the options they can choose for this journey,” she told HealthandMe.
She also criticized the tendency to dismiss menopausal symptoms as a “normal” part of aging without offering support or treatment options.
“Women are not broken. Menopause is not a disease like cancer that has to be cured. But women need support. We don’t need to normalize suffering,” Lisa said.
Speaking about aging and post-menopause life, Lisa argued that society often dismisses older women despite what she described as a biologically important phase of life.
“We’ve had terrible PR as aging women. We are dismissed and considered irrelevant when actually we’re stepping into our power age if we know how to take care of ourselves,” the acclaimed actress told HealthandMe.
However, the problem arises when menopause is left unaddressed, and the hormonal changes cause long-term health impacts, including bone health, heart disease risk, and possibly dementia.
“The problem is with the drop in hormones. If you don’t have strategies and lifestyle changes to support yourself post-menopause, you become a frail woman. Your bones suffer. You’re more prone to heart disease and possibly even dementia,” she said, urging more women to seek medical help during menopause and not suffer in silence.
