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.

A tiny sore in your mouth might not seem like a big deal until it starts to sting every time you eat, drink, or even breathe. Mouth ulcers are more common than we give them credit for. Usually, they’re nothing to worry about. But if they’re showing up a bit too often or staying longer than usual, it’s time to pay attention.

Here’s a look at when to shrug it off, when to switch to soup, and when to book that appointment with your dentist or GP.

Ulcers Happen But Not All Should Be Ignored

Normally, ulcers usually clear up within two weeks and are often linked to being run down or low on certain vitamins. But if that ulcer refuses to budge after three weeks, it’s not something to ignore. Cancer Research UK recommends seeing a doctor or dentist if an ulcer or a red or white patch is still hanging around after three weeks. It could be harmless, but it could also be your body waving a little red flag.

DIY Healing

Most mouth ulcers don’t need a lot to treat. The NHS says they’ll usually heal with time and a little TLC. That said, you can speed things up by not doing things that make them worse.

Skip the spicy curries, salty snacks, acidic foods, and crunchy culprits like toast or crisps. Basically, if it hurts to eat it, you shouldn’t be eating it. Hot and acidic drinks like fruit juice are also a no-go. As for toothpaste, check the label, avoid ones with sodium lauryl sulphate, a foaming agent that can irritate ulcers.

Instead, go soft and soothing. Stick to cool drinks, go for gentle foods, and switch to a soft-bristled toothbrush that won’t scratch or poke at sensitive areas. Regular dental check-ups and a balanced diet also go a long way in keeping your mouth happy.

Not All Ulcers Are Created Equal

Most of the time, ulcers are just that: temporary sores. But if you’re dealing with one that refuses to heal, is especially large or painful, or comes with other symptoms like swelling, difficulty eating, or a lump in the neck, don’t play the waiting game. It might be something more serious, like an infection or in rare cases, something that requires more thorough investigation.

Prevention

If you’ve had your fair share of ulcers and want to avoid the next round, the answer lies in prevention. Aside from dodging the usual food triggers, it helps to manage stress, get enough sleep, and eat a diet rich in iron, folate, and B vitamins. Also, drink plenty of water and make sure your mouth stays clean.

Regular dental visits help your dentist spot the early signs of anything unusual and give you personalised tips on how to avoid recurring ulcers.

Don’t Panic, But Don’t Ignore

Mouth ulcers are rarely serious. Still, it’s better to be safe than sorry. If your ulcer overstays, refuses to heal, or comes with other odd symptoms, get it checked. And while you wait it out, treat your mouth gently. Avoid fiery foods, switch to a soothing routine, and try not to poke at it with your tongue.

If you’ve ever felt your heart rate spike just because your phone buzzed during dinner, you’re not alone. In our hyper-connected lives, notifications can set off a full-blown biological alarm. But what’s happening inside you isn’t just “in your head”; it’s ancient biology meeting modern tech, and the result is often anxiety, chronic stress and, eventually, burnout.

Here’s why you panic every time that screen lights up and how to stop spiralling into stress over a simple message.

Your brain may be rational, but your hormones have other ideas. According to reports, the moment a message lands, especially one that feels urgent or work-related, your body launches into ‘fight or flight’ mode.

Cortisol, the stress hormone, floods your system and primes you to react. And if the ping is from your boss or an emotionally charged source, the cortisol surge can be even more intense.

To make things worse, adrenaline often tags along. This amps up alertness, raises your heart rate and makes it nearly impossible to relax. Your brain is preparing you to flee from danger even if the only threat is an email with the subject line “quick update”.

The Dopamine Trap

Just to complicate things, dopamine, the pleasure chemical, also plays a part. Every time you check your phone and respond, your brain rewards you with a little shot of satisfaction. That’s why it’s so easy to get hooked and why you keep checking even though it stresses you out.

When Oxytocin Gets Triggered

Normally, messages from loved ones trigger oxytocin, the hormone that helps us bond and feel safe. But when the messages are draining, demanding or tied to work, that warm fuzzy feeling gets pushed out by stress chemicals. Over time, this can disrupt your ability to be present and genuinely connect with others, leading to burnout.

Melatonin Meltdown

And if you’re checking those pings before bed, you should stop. Reports warn that notifications late at night reduce the production of melatonin, the hormone responsible for quality sleep. Without it, you may struggle to nod off, stay asleep or feel rested, fuelling a cycle of fatigue, brain fog and even more stress.

The Long-Term Fallout

If this sounds like an exhausting loop, it is. Consistent cortisol spikes and dopamine hits can wreak havoc on your health. Think weight gain, insomnia, poor focus and a fried nervous system. In fact, studies show that 76 per cent of millennials and 40 per cent of baby boomers admit to feeling anxious the moment their phone lights up.

Here are a few tricks to help you break the cycle.

1. Set Notification Boundaries

Draw a digital line in the sand. Turn off alerts after a set time or batch-check messages every few hours instead of reacting instantly. Use your phone’s ‘Do Not Disturb’ mode to protect time for real life.

2. Mute the Noise

Not every ping is essential. Reports suggest turning off non-urgent app and group chat notifications. Fewer pings mean fewer cortisol spikes and less temptation to fall down the notification rabbit hole.

3. Prioritise In-Person Conversations

Texts are easy to misread, and fast replies aren’t always the best ones. If possible, have real conversations with friends, colleagues or family. Face-to-face talks promote oxytocin, reduce stress and avoid unnecessary misunderstandings.

4. Train Yourself to Pause

Next time your phone buzzes, don’t jump. Take five deep breaths. Count to five. Ask yourself if the message needs an immediate reply. This tiny pause rewires your stress response and reins in that hormone cascade.

5. Keep Work Messages in Their Lane

When work bleeds into personal time, stress seeps in. It is recommended to have a chat with your manager or team about boundaries. Set a window for work-related conversations and stick to it. Your wellbeing shouldn’t be a casualty of always being “available”.

The interesting thing about people is how unique everyone’s perspectives are. Everyone has their way of thinking, their own way of doing things as well as their own unique memories. These aspects make us human and set us apart from everyone. Can you imagine losing all of these because of a disease that robs you of your cognitive abilities? Dementia is not as uncommon as we think it is. Affecting millions, we are yet to find a cure for this disease. While researchers have identified risk factors, does changing them make any difference?

A new study asked an important question: Can making specific changes to our daily lives actually improve or protect our thinking skills as we get older, especially for those who might be at risk of memory problems or dementia?

Organized Efforts Work Better

This study involved over 2,100 older adults who faced a higher chance of their thinking skills declining. We compared two different groups over two years. One group followed a well-organized plan for healthy living. This plan included regular moderate to intense exercise, sticking to a special "MIND diet," doing activities that challenge the brain and encourage spending time with others, and regular checks on heart health. The other group got a less organized plan that they had to follow more on their own.

This was a big study where neither the participants nor the initial assessors knew which group someone was in. It took place in 5 different medical centers across the U.S. from 2019 to 2023. We included 2,111 people between 60 and 79 years old who weren't very active and didn't eat the best diet. To make sure we studied people truly at risk, they also had to have at least two other risk factors, like a family history of memory issues, heart problems, or just being older.

• Structured Group, who received a detailed, ongoing plan for exercise, diet, brain-challenging activities, social time, and heart health checks. They had more guidance and were regularly checked on.
• Self-Guided Group, who got general advice on the same healthy lifestyle areas but had less structure and fewer regular check-ins.

The main goal was to see how much a person's overall thinking ability changed each year over the two-year study. We used a combined score that looked at different brain skills like planning, remembering things, and how quickly their brain worked.

Results of the Study

Out of all the people who started, almost 90% finished the two-year assessment. Both groups showed some improvement in their thinking scores over time. However, the structured group's improvement was clearly bigger than the self-guided group's.

Interestingly, the benefits of the structured program were helpful whether or not a person carried a specific gene (APOE 4) linked to Alzheimer's risk. But, the structured program seemed to help those who had lower thinking abilities at the beginning of the study even more.

We also kept track of any problems or side effects. The structured group actually reported fewer serious and non-serious problems compared to the self-guided group. The most common health issue overall was getting COVID-19.

What This Means for You

The results clearly showed that the organized group had a noticeably better improvement in their overall thinking abilities. Their brain scores went up more each year compared to the group that followed the less organized plan. This means that having a structured approach made a bigger positive difference for their brains.

The findings suggest that if you're an older adult at risk of memory problems, a structured, more involved healthy lifestyle plan is more helpful for your thinking skills than trying to do it all on your own with less guidance. We still need more research to see how much these brain improvements affect daily life and if they last for many years.

It's really important to find ways to slow down or prevent memory loss that can lead to dementia. Things we can do in our daily lives, like changing our habits, are promising because they are usually affordable, easy to access, and safe. They offer a good way to protect our brains without relying on medicines alone.
