We all must have come across the phase: this is why women live longer than men. These are all over the social media, where men are performing more often than not, some experiments, without gears, just for fun, "in the name of science". The caption reads: this is why women live longer. However, is there really a science to it, other than the fact that women choose to do things more safely?

In the United States, women have a life expectancy of about 80, whereas men have 75. Women outlive men and this holds true regardless of the country women live, the money they make, and other factors. In fact, it is true for most other mammals too.

Dr Dena Dubal, a professor of neurology at the University of California, San Francisco told the New York Times, "It is a very robust phenomenon all over the world, totally conserved in sickness, during famines, during epidemics, even during the times of starvation."

But what are the reasons? These reasons are often more complicated and less established. It is important to note that only because women are outliving men does not mean they are living a better life. In fact, women tend to have shorter health spans, which means the number of healthy years in a person's life is less in women than men, confirmed Bérénice Benayoun, an associate professor at the U.S.C. Leonard Davis School of Gerontology.

As per a 2021 study titled, Sex differences in frailty: Comparisons between humans and preclinical models, found that women are more physically grail than men in old age. They are also more vulnerable, especially after menopause and are at more risk of developing cardiovascular issues and Alzheimer's disease because of age.

The key is in figuring out what makes one sex more resilient or vulnerable.

Genetics

For things which do not find easy explanations, scientists look for their answers in genes. Many research, including a 2020 study titled, The sex with the reduced sex chromosome dies earlier: a comparison across the tree of life, suggests that the XX set of female sex chromosomes may impact longevity. However, there has not been any clarity on how it affects longevity.

Another 2018 study titled, Female XX sex chromosomes increase survival and extend lifespan in aging mice, which was conducted by Dr Dubal's lab, looked at genetically manipulated mice with different combinations of sex chromosomes and reproductive organs. It was found that those with two X chromosomes and ovaries lived longest, followed by mice with two X chromosomes and testes. Mice with XY chromosomes had shorter life spans.

"There was something about the second X chromosome that was protecting the mice from dying earlier in life, even if they had testes. What if there was something on that second X chromosome that was in some ways a sprinkle of the fountain of youth," says Dr Dubal. While scientists have not yet looked at this factor in humans, Dr Dubal suggests that humans have the same hormones and sex chromosomes, and similar reproductive system that could corroborate the similar findings in people.

Hormones

Plenty research has shown that estrogen is responsible for longevity also effect on the immune system. The data also shows that before menopause, the female immune system tends to do better. In fact Dr Benayoun said that males tend to do much worse in response to infection.

Another 2017 study titled, Ages at Menarche and Menopause and Reproductive Lifespan As Predictors of Exceptional Longevity in Women: The Women's Health Initiative, found that women who experienced menopause later in life over the age 50 lived longer than those who experienced it earlier.

Lifestyle and Behavior

There are also disparity in behavioral patterns between men and women. This includes smoking, drinking heavily, which can contribute significantly to mortality. Women also have more "health promoting behavior", believe experts. Women are also more likely to socialize than men and thus it protects them from detrimental effects of social isolation and loneliness. In fact, a 2023 analysis published in Jama Network, titled, Widening Gender Gap in Life Expectancy in the US, 2010-2021, found that women are less likely to die by drug overdose or suicide.

Vaccination has been the most powerful and effective tool in modern medicine that improves the body's immune system and fights off diseases, saving millions of lives annually.

Vaccines reduce the risk of getting a disease by working with your body’s natural defenses to build protection. Vaccines are available to prevent more than 30 life-threatening diseases and infections, helping people of all ages live longer, healthier lives.

According to the World Health Organization (WHO), immunization currently prevents 3.5 million to 5 million deaths every year from diseases like diphtheria, tetanus, pertussis (whooping cough), influenza, and measles.

While vaccines are available for both young and old, former director of AIIMS New Delhi, Dr Randeep Guleria, in a post on social media platform Instagram, urged doctors to recommend these based on people's age and the presence of comorbidities.

“Two very important factors one has to consider when recommending a vaccine for the adult population. One is the age, and if you have a patient over the age of 60 years, vaccination is definitely something you should recommend, or if a patient has associated comorbidities which increase the chance of vaccine-preventable diseases,” said the noted pulmonologist from Medanta Hospitals, Gurugram, in a Doctor's Special Series.

He recommended doctors to prescribe six types of vaccines for adults, namely:

• Influenza Vaccine

“It can be given as a pre-winter vaccine, which is a northern hemisphere vaccine, or it can be given in May or June when it is a southern hemisphere vaccine,” he added.

A flu vaccine typically reduces the risk of influenza infection, prevents severe illness, and complications.

• Pneumococcal Vaccine

“For the pneumococcal vaccine, we now have a conjugate vaccine, which is available as PCV20, which is once in a lifetime, and that has made things much more easier,” Dr. Guleria said.

The PCV20 vaccine guards against 20 strains of pneumococcal bacteria. It also prevents serious pneumonia, invasive infections, and related complications. It is recommended for adults aged over 65 and those with weakened immune systems.

• Shingles Vaccine

The vaccine against shingles prevents the risk of viral infection that causes a painful rash and nerve damage. It also helps prevent long-term nerve pain and prevents serious complications from shingles. The vaccine is safe for adults 50 and older.

• Tdap vaccine

The Tdap vaccine protects against pertussis infection, also known as whooping cough. It guards against tetanus infections and reduces the risk of diphtheria and related complications.

• HPV vaccine

Beyond cervical cancer, the HPV vaccine also protects against anal and throat cancer. It prevents 90 percent of HPV-related cancers, is safe, and effective. It also prevents genital warts.

For most parents, even a slight rise in temperature can feel alarming. The instinct is to act quickly: cooling up the body, layering up, or trying every home remedy possible. But not everything we’ve grown up hearing about fever may actually be correct.

In a post on social media platform Instagram Dr. Ravi Malik, a New Delhi-based Pediatrician shared few simple, and scientific facts that can make managing fever far less stressful and far more effective.

Cold Water Isn’t The Answer

The use of cold water sponging is one of the most frequently used methods against fever. However, it can turn out to be counterproductive. Very cold water may cause discomfort and might even induce shivering, which results in increased body temperature instead of reduced one. Therefore, the safest and most efficient way of cooling the body down gently is by using the water from a normal tap.

Light Clothing Helps The Body Regulate

It may appear to be a good idea to cover a child with fever, but overdressing inhibits the heat from escaping. In fact, the body must be given a chance to release heat, and clothes that are too heavy prevent that. Clothes that are loose and made of fabrics that allow better air circulation facilitate the body's natural temperature regulation.

Don’t Rush To Sponge At 100°F

There are times when a temperature increase should not be considered a problem. Sponging a fever of about 100°F is not necessary and could be painful. Fever is the body's way of fighting infection, and mild fever does not always need the application of strong cooling measures.

Hydration Is Key

Fever makes the body lose fluids at an increased rate which can rapidly lead to dehydration. Therefore, providing fluids is absolutely essential to the care process. It does not matter whether it is water, milk, or any other liquid - giving the child plenty of fluids is the first step towards healing and is also a means of temperature control from the inside.

Sponging Should Be Full-body

When sponging, concentrating only on the forehead is clearly insufficient. Fever is a systemic response, not a localized one. So gentle, full-body sponging especially on areas like arms, legs, and torso will enable more efficient cooling.

Fans And ACs Are Not The Enemy

A player in the span of fever myths is that a fan or air conditioning must be turned off. However, in fact, a well-ventilated, comfortably cool room actually helps the body relax. It is perfectly okay to continue running the fan or AC, as long as the room is not excessively cold.

Not Every Temperature Is A Fever

A temperature of 99°F often causes unnecessary panic, although it is not a real fever. Being aware of this helps prevent overreaction and allows parents to keep their eyes on the actual symptoms rather than just numbers.

The Takeaway

Dr. Ravi Malik, also the Chairman of Radix Healthcare, points out that handling fever isn't about short-term fixes, but rather about understanding and taking care. When the method is correctly followed - mild cooling, enough water intake, and a composed state of mind fever is much less challenging. And quite often, it is as beneficial to know what not to do as knowing what to do.

A Cancer-hit US couple in North Dakota has shared their ‘nightmare’ experience with dual diagnosis of the deadly disease and parenting their three children.

Spencer Eddy, a 39-year-old father of three, suffered from dizzy spells for years. While doctors dismissed the condition as vertigo, it turned out to be a brain tumor, People reported.

MRI scans in April 2024 revealed that he had a tumor the size of a lime in his brain. Further scans and tests at Mayo Clinic in October confirmed medulloblastoma -- a malignant tumor that is located on the part of the brain that controls coordination and movement.

According to the Mayo Clinic, it is most common in children, but can occur in adults.

“When we found out that Spencer had a brain tumor, we were terrified,” said Jolene, his wife. “They said the cancer was blocking the fluid that flows from your vein to your spinal cord. They said they didn't know how he was still walking and talking, and how he hadn't had a stroke."

A week later, Spencer underwent a 10-hour surgery, and doctors were able to remove 85 percent of the tumor. Along with radiation and chemotherapy, he also needed speech and physical therapy to relearn how to walk and talk, People reported.

What came as a double blow to the couple was Jolene’s breast cancer diagnosis in April 2025.

“Whilst we were in the hospital, I noticed a small pea-sized lump under my armpit, but I put it to the back of my mind, because of everything that was going on with Spencer,” she recalled. “Doctors said it was probably just a cyst, but I asked for it to be removed anyway, and when it came back from testing, I found out it was breast cancer. I was absolutely floored.”

The doting parents “were so devastated and scared about what would happen to their kids”, if both of them die.

Following her diagnosis, Jolene was given hormone blockers and underwent a double mastectomy while Spencer was still undergoing chemotherapy.

Jolene struggled after the surgery and was vomiting and passing out frequently. She ultimately needed a blood transfusion and was able to recover.

It was hard for Jolene to take care of the family as Spencer could not walk well or drive.

"We're living most people's nightmare, but we're feeling optimistic about the future,” she said. “We have a long life, and we're going to fight for it; we're not going to give up.”

Spencer completed treatment in April 2025 and now has no evidence of cancer. Jolene also has no evidence of cancer. The couple now goes to appointments with their oncologists together as they hope to ensure their tumors don't grow back, the report said

Can A Brain Tumor Cause Dizziness?

While dizziness by itself is not a common symptom of a brain tumor, some tumors can trigger headaches and bouts of nausea and vomiting that may be associated with a dizzy feeling.

Dizziness, also called vertigo, is however, associated with tumors that develop in the cerebellum—the part of the brain that controls movement.

Medulloblastoma, a type of brain tumor, forms when cells in the cerebellum develop changes in their DNA. These changes cause the cells to grow and multiply quickly, as per the Mayo Clinic.

Common signs and symptoms of medulloblastoma may include:

• Dizziness.
• Double vision or other vision changes.
• Headaches, which are often worse in the morning.
• Nausea or vomiting.
• Poor coordination.
• Tiredness.
• Difficulty with balance or an unsteady walk.
