When it comes to boosting longevity, most of us focus on the usual suspects: nutrition, exercise, sleep, and mental well-being. But an often-overlooked player in the body’s symphony of wellness is gaining traction — the vagus nerve. It’s being touted by wellness influencers and researchers alike for its potential to reduce inflammation, support brain and heart health, and even improve life expectancy.
Might tickling your vagus nerve actually extend your lifespan? Here's all you need to know — from the science to the trends and the practical tools that might unlock a longer, healthier life.
The vagus nerve is the body's longest cranial nerve, running from the brainstem down to the abdomen. It is part of the parasympathetic nervous system that controls what's commonly termed as the "rest and digest" response. This strong nerve conveys messages between the brain and the large organs, such as the heart, lungs, gut, and liver.
In essence, the vagus nerve regulates:
Its wide-reaching impact on critical functions makes it a crucial component of homeostasis. With the vagus nerve operating at its best, it promotes an internal equilibrium that mitigates stress, diminishes inflammation, and keeps the body ready to repair — all essential for longevity.
Vagus nerve stimulation (VNS) is not an alternative theory. It's an FDA-approved therapy for a number of conditions, including treatment-resistant depression, epilepsy, cluster headaches, and migraines. Clinically, VNS usually involves an implanted device that sends electrical pulses to the nerve. The Cleveland Clinic and Mayo Clinic report that VNS is also being looked at as a treatment for inflammatory bowel disease and rheumatoid arthritis.
A 2022 review in Clinical Science built on the nerve's wide therapeutic potential, mentioning its effect on systemic inflammation and autonomic control. Both functions, when dysregulated, are commonly precursors to age-related disease — suggesting why VNS could be involved in prolonging both lifespan and healthspan.
The vagus nerve has blown up online over the last few months, with influencers promoting do-it-yourself methods to "reset" the nervous system. These trending techniques are:
Though the methods are being pitched for calmness, is there actually science backing the trend?
In a 2020 study in Scientific Reports, researchers determined that some head and neck massage could reduce stress levels by activating the parasympathetic system. But again, the same study revealed that even typical shoulder massages provided the same benefit, which indicated that relaxation is not necessarily from the activation of the vagus nerve alone.
"The relaxation response probably comes from a combination of mechanisms," explains [Expert Name], a clinical researcher and neurologist. "Deep breathing, touch, and body awareness all regulate the nervous system, not the vagus nerve in isolation."
Although these exercises are usually low-risk, professionals warn against following social media blindly without knowing the complete scenario.
“There’s a risk in assuming these techniques are universally safe,” [Expert Name] warns. “For individuals with certain medical conditions — like cervical spine issues or heart arrhythmias — overstimulation or incorrect technique could do more harm than good.”
If you’re considering vagus nerve exercises, especially as a part of a broader health or stress management strategy, consult your healthcare provider first.
If you’re looking for science-backed ways to engage your parasympathetic nervous system and enjoy the benefits associated with vagus nerve stimulation, here are expert-recommended strategies:
One of the easiest tools at hand is slow, diaphragmatic breathing. Research, including one appearing in Sleep Medicine, supports that slow breathing increases parasympathetic activity. The 4-7-8 technique — breathe in for 4 seconds, hold for 7, breathe out for 8 — promotes a decrease in heart rate and blood pressure, lowering strain on the body's systems with repeated use.
Cold water stimulation, particularly to the face, has been associated with vagus nerve activation. This activates the "diving reflex," which slows heart rate and increases vagal tone, giving a calming physiological reboot.
Since the vagus nerve is linked to the vocal cords, vibration created from humming or chanting can potentially stimulate it. Anecdotal reports and small studies indicate that this may encourage relaxation and emotional regulation.
Exercise is still one of the best, long-term methods to maintain vagal tone. In a European Journal of Applied Physiology study, regular aerobic exercise increases parasympathetic function — not only during the exercise session, but for hours post-exercise. It helps deliver better cardiovascular resilience and emotional health, both of which correlate to increased life expectancy.
Although we’re still in the early stages of research, there’s a growing consensus among scientists that vagal tone — or the strength of vagus nerve activity — plays a central role in predicting health outcomes. Low vagal tone has been associated with:
On the other hand, increased vagal tone is associated with a more effective stress response, improved sleep, decreased inflammation, and increased heart rate variability — all characteristics of a healthy, adaptable system and increased lifespan.
"Stimulating the vagus nerve might not be a magic pill," states [Expert Name], "but when it is part of an integrative health regimen, it can definitely tip the scale in your direction."
In an era of busy schedules and incessant digital white noise, activating the body's natural calming systems may be a longevity game changer. As much as science continues to develop the vagus nerve stimulation space, one thing is certain: activating the parasympathetic nervous system — through breathing, cold showers, or everyday movement — can be a critical component in fine-tuning both physical and mental well-being.
And the more that researchers dig, the sooner we could find out that this humble nerve contains the key not only to relaxation, but to a healthier, longer life.

Every year on March 20, World Oral Health Day is observed to raise awareness about the importance of caring for your mouth at every stage of life. This means starting from birth through later years. However, a visit to dentist is usually the last thing anyone plans when they think of a doctor's visit. Dental visits happen only when extraction or something bigger is involved. More often than not people ignore a follow up or a regular dental checkup to maintain oral health. Why so?
In a previous interview with Health and Me Lt Gen Dr Vimal Arora, the Chief Clinical officer at Clove Dental, who has 40 years of experience as a dentist and also served in the Indian Army explained how oral health is not just about a pretty smile. He explained that many do not plan a regular visit to a dentist because the problems that pertains to oral health do not seem "life threatening".

However, Dr Arora told Health and Me that oral health can in fact be the first way to know if anyone is prone to a chronic disease.
“There is now scientific evidence, published in top medical journals, that shows how oral infections can significantly worsen pre-existing systemic diseases,” says Dr. Arora. This isn’t just a theory — it’s a medically established fact.
Take diabetes, for instance. People with gum infections often find it harder to control their blood sugar levels. “If you're suffering from diabetes and you have a gum infection, your diabetes will not be well controlled. In fact, it may worsen,” he adds. The same applies to heart diseases. Oral infections can increase inflammation in the body, potentially triggering or worsening cardiovascular problems.
This is concerning especially for those people who may already be managing conditions like hypertensions, arthritis, or respiratory illness. Poor oral health can actually sabotage their efforts to stay stable.
“Your tongue is a true mirror of your oral and general health,” says Dr. Arora. The correlation therefore goes beyond just gums and teeth. Dentists are trained to detect early signs of systemic disorders simply by examining the tongue's color, coating and texture.
A pale tongue might indicate iron deficiency, while a coated tongue could be a sign of digestive issues or a viral illness. “Sometimes, we ask patients if they've had their blood work done, based purely on what we see on their tongue,” he adds. In some cases, dentists can even detect undiagnosed diabetes or early signs of nutritional deficiencies.
Dr. Arora also highlights the overlooked risks that pregnant women face when they neglect their dental hygiene. “If you are pregnant and suffer from periodontitis or even gingivitis — essentially poor gum health — you are at risk of having a preterm or low-birth-weight baby,” he says.
This isn’t just theory; it’s a well-documented risk in obstetric dentistry. Pregnant women are encouraged to get dental check-ups not just for themselves, but for the health of their unborn child.
Despite these evidences, oral health remains one of the most neglected aspects of personal healthcare. Dr. Arora believes this is partly due to a lack of awareness and the perception that dental problems are not "serious enough."
“People often wait until they’re in pain before they see a dentist, but by then, the damage might already be affecting other parts of the body,” he says. Preventive check-ups, regular cleaning, and treating gum infections early on can go a long way in improving not just oral health, but overall wellness.

Most people reach for sunscreen when heading to the beach or stepping out for a long day in the sun. But skincare experts say sun protection should not be limited to vacations or outdoor activities. Sunscreen is meant to be part of a daily skincare routine.
This often raises a common question. If you are staying indoors all day, do you still need sunscreen?
Dermatologists say the answer depends on your surroundings and daily habits.
Many people assume that staying inside completely protects their skin from sunlight. But this is not always true.
Dr Khushboo Jha, MBBS, MD, Chief Dermatologist Consultant at Metro Hospital and Founder of One Skin Clinic, explains that sunlight entering through windows can still affect the skin.
“While standard window glass blocks most UVB rays, which cause sunburn, UVA rays can still pass through. These rays penetrate deeper into the skin and are linked to long term concerns such as premature aging, uneven pigmentation and loss of skin elasticity,” she says.
These UVA rays are often overlooked because they do not cause immediate redness or burning like UVB rays. However, over time they can lead to visible signs of skin aging and pigmentation.
Dermatologists say sunscreen indoors is particularly useful for people who spend long hours near windows or in well lit spaces.
Dr Jha notes that individuals who work near windows, sit in sunlit rooms or spend time driving during the day may still be exposed to sunlight. “Even short periods of daily exposure to sunlight over time can contribute to cumulative skin damage,” she explains.
In such situations, applying sunscreen in the morning can offer an added layer of protection. A broad spectrum sunscreen with at least SPF 30 is generally recommended.
This approach is especially relevant for people working in offices with large windows or those who frequently commute during daylight hours.
Experts also say sunscreen use indoors is not always equally necessary for everyone.
If you spend most of the day inside a room with minimal natural light and away from windows, your exposure to ultraviolet radiation becomes much lower.
Dr Jha says that in such cases the urgency of frequent sunscreen reapplication becomes less important. The risk of sun related skin damage is significantly reduced when there is little to no direct daylight entering the space.
This means sunscreen indoors should not be treated as a strict rule but rather as a flexible part of skincare based on lifestyle and environment.
Another topic that often comes up is blue light exposure from digital devices such as phones, laptops and tablets.
Some studies suggest that prolonged exposure to visible light may contribute to pigmentation, especially in individuals with deeper skin tones. However, dermatologists point out that the amount of blue light from electronic screens is much lower than what we receive from natural sunlight.
Dr Jha says the effect of digital screens on the skin is still being studied, but compared to sun exposure, the impact remains minimal.
Dermatologists suggest viewing sunscreen as a preventive skincare habit rather than a rigid rule.
Dr Jha recommends incorporating sunscreen into your morning routine, particularly if your day includes stepping outdoors or spending time in naturally lit environments.
In simple terms, if daylight reaches your workspace or you plan to go outside later in the day, applying sunscreen in the morning is a small step that can help protect your skin over time.

At the age of 28, Courtney Paton realized she could never have children. She was medically infertile. This was after years of repeated surgeries, a total of seven, for 'suspected' endometriosis, due to which Dr Simon Gordon, Melbourne-based gynecologist removed both her ovaries and eventually her uterus.

Her story came to light through an investigation by the Australian Broadcasting Company or ABC's Four Corners, an investigation that looked at the treatment she received from Dr Gordon.
Courtney says she trusted the doctor completely. Now she says that trust has been shattered. “I feel completely betrayed by not only Simon Gordon, but by Epworth, by the healthcare system,” she told the program.
Courtney first had laparoscopic surgery in 2018 with another surgeon, which confirmed she had endometriosis. The condition affects about one in seven Australian women and can cause severe pelvic pain and fertility problems.
Still struggling with pain, she began seeing Gordon in 2019 when she was 21.
Over the next several years she underwent seven surgeries with him. Gordon told her the procedures were necessary to treat severe endometriosis. Courtney and her family paid more than 32,000 Australian dollars for these surgeries alone.
But when investigators asked her to obtain her pathology reports, the results told a very different story. The tissue tests from most of her surgeries showed no evidence of endometriosis.
Despite this, operation reports written by Gordon continued to describe findings consistent with the disease.

In 2021 Gordon removed one of Courtney’s ovaries, saying it was stuck to the pelvic wall. Later he removed the second ovary as well.
Independent specialists who reviewed the pathology for the investigation said the ovary appeared normal and there was no clear justification for removing it. One expert described the treatment as “unbelievable” after reviewing the medical records.
Medical guidelines generally advise caution when removing ovaries from young women who may want children in the future.
Despite losing both ovaries, Courtney continued to experience pelvic pain. Gordon later advised that she should undergo a hysterectomy.
Concerned, she sought a second opinion from another gynecologist who said the procedure was unnecessary and suggested non surgical treatments.
But after years of pain and repeated surgeries, Courtney says she felt desperate for relief and trusted the doctor who had treated her for so long. Her uterus was removed in 2023 when she was just 25.
Again, pathology results found no evidence of endometriosis.
Courtney is now pursuing legal action through a medical negligence claim. The case has also drawn attention from regulators, with investigations underway into Gordon’s conduct.
Australia’s federal health minister Mark Butler described the allegations as “physically sickening”.
For Courtney, the emotional impact remains overwhelming.
“No woman should ever have to endure what I’ve endured,” she said. “I’ve had the opportunity to have a family taken away from me.”
