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 consumption of vapes or the practice of vaping has seen a surge among the younger generation. People have often considered vapes to be a substitute for their everyday cigarettes, and therefore, they have replaced their traditional smoking habits. They do not carry the right knowledge about this common practice and fail to take the right measures to cut down on its usage. Research institutions and government bodies are now making collective efforts to establish the facts and make the general populace more aware and healthy.

How Can You Detect The Early Signs Of Oral Cancer?

Oral problems and an increased risk of oral cancer are considered to be the common problems associated with vaping. The presence of harmful chemicals in its formation makes it harmful to the human body. Along with your oral cavity, they can also damage the lining of your mouth. It has been proven that excessive consumption of vapes can lead to an increased risk of oral cancer.

Oral cancer can be prevented with early detection and immediate medical intervention. It can be identified with signs like abnormal bleeding inside the mouth, ulcers that won’t heal, chronic soreness, and red and white patches on the tongue and gums. The common signs are often discarded as an allergy, and people fail to seek the right treatment. Even with the available medical care and support, they are not able to counter this deadly disease.

The Impact of Vaping on Oral Tissues

The risk of vaping is not limited to increased chances of getting oral cancer. It can also impact your overall health. A vape is made with excessive heat and other harmful chemicals, which can damage the tissues of your gums and cause inflammation. It can lead to a condition known as gingivitis. One might also experience a dryness in their mouth, which is caused by reduced saliva production, which is considered to be a defense mechanism against bacterial production.

There can be far-reaching implications of having a constant dry mouth. It can lead to a breeding ground for harmful microbes. It can also increase one’s chances of having tooth decay, foul smell in the mouth, and oral infections.

The presence of flavoring agents and harmful chemicals in vapes makes them more damaging to the enamel of your teeth. In the short run, it might not seem like a major problem, but it can lead to tooth sensitivity if not handled at the right time.

Which Is More Harmful- Smoking or Vaping?

As the practice of vaping does not include combustion, people consider it safer than regular smoking. They often forget that vapes contain a significant amount of nicotine, which promotes survival and rapid growth of cancerous cells.

Vaping can reduce the blood flow to your gums and affect your healing capabilities. It can also increase your probability of periodontal disease. As the younger generation considers vaping to be a safer alternative, it can lead to its more frequent usage. As vaping does not follow any pattern like traditional smoking, it can be consumed at any time during the day, and increases your exposure to harmful chemicals.

The younger generation has reported an increasing number of oral health issues that are linked to vaping. Some of these problems include inflammation of your gums and decay of

your tooth enamel. As these issues seem visibly minor, they can often get ignored, and the person might not seek the required treatment. Consequently, they might develop long-term oral problems.

The younger generation gets influenced by the internet fads and more affordable alternatives to their daily smoking. As they keep increasing their consumption of vapes, they fail to identify the potential side effects.

Conclusion

The ongoing research has proven that vaping can be detrimental to both your oral and overall health. Research has suggested that this problem is more common among the younger generation, who might feel more inclined to replace the traditional forms of smoking. With ease of usage and accessibility, this malpractice has youngsters across the globe under its grip.

If one does not make the right effort to reduce their usage, it can lead to serious complications in the long run. Both the government officials and healthcare professionals need to spread more awareness about its detrimental effects and make efforts to conduct regular oral checkups. In this way, there will be a community-level effort to put a stop to its usage.

Bob Harris, the renowned BBC Radio 2 host, has informed his listeners of being hospitalized again for prostate cancer treatment.

Posting on social media platform Instagram, Harris said he is receiving treatment for an issue that has developed over the past few weeks.

“As many of you know, I suffer from prostate cancer, and every now and again I experience setbacks that need attention. Now is one of these moments,” he wrote, along with a picture of himself lying in a hospital bed while smiling for the camera.

Harris noted that he’s taking short break away from his programs. However, he confirmed that this week’s Country Show is scheduled as planned, and his Sounds of the 70’s episode on 12th April will feature an 80th birthday celebration special he recorded before attending the C2C Festival with Zoe Ball.

Noting that he can’t state the day of his return as the host, he said: “I know that I will come back… and come back stronger”.

“I hate missing programs and I am keen to get back into the studio as soon as I can”.

Calling himself “blessed” for the support he received from friends and family and listeners of his show, Harris said that during his absence, Darius Rucker will guest on Country, while Shaun Keaveny will cover Sounds of the 70’s for a few weeks.

"I am so blessed to have the love of my family and the support of my friends who have rallied round me at what has proved to be an unexpectedly testing time,” Harris said.

Prostate Cancer: The UK’s Most Common Male Cancer

Prostate cancer remains the most common cancer among men in the UK, with around 55,000 cases diagnosed every year. Despite this, there is currently no national screening program because of concerns over the accuracy of PSA tests.

In November 2025, former UK Prime Minister David Cameron revealed his prostate cancer diagnosis and also called for a targeted screening.

In an interview with Times, he said, "You always hope for the best. You have a high PSA score - that is probably nothing. You have an MRI scan with a few black marks on it. You think, ‘Ah, that’s probably OK.’ But when the biopsy comes back, and it says you have got prostate cancer. You always dread hearing those words. And then literally as they’re coming out of the doctor’s mouth you’re thinking, ‘Oh, no, he’s going to say it. He’s going to say it. Oh God, he said it.’"

The former PM, said that he had a prostate-specific antigen (PSA) test for the screening that looks for proteins associated with the form of the disease. His result was high, and a biopsy after that revealed his cancer.

In October 2024, six-time Olympic gold medallist Chris Hoy revealed he had been diagnosed with terminal stage 4 cancer. His prostate cancer had spread to his shoulder, pelvis, hips, ribs and spine.

A woman’s health check-up is not about being paranoid. It's about refusing to treat your body as an afterthought.
