Every year, World Brain Day is marked to raise awareness around brain health and neurological conditions that often go undiagnosed or misunderstood. This year’s theme focuses on brain health and early detection, emphasizing how subtle signs—often brushed off as routine stress—may actually be the brain’s way of raising an alarm.

While stress-related fatigue, burnout, and tension headaches are all-too-common in today’s never-resting, always hustling world, experts warn that dismissing persistent or unusual neurological symptoms as “just stress” could delay diagnosis of something more serious, such as a brain tumor.

We spoke with Dr. Mukesh Kumar, Director and Head (Parkinson's Disease Unit), Neurosciences, Neurology, Max Super Speciality Hospital, Saket, to understand the difference between stress symptoms and potential red flags.

Not All Headaches Are Just “Stress Headaches”

Headaches are the most common symptom people link with stress, but not all headaches are created equal.

Dr. Kumar explains, “A worst headache in the morning may be a feature of subarachnoid haemorrhage (SAH), which is a medical emergency. Stress headaches are usually mild to moderate and without vomiting. SAH is usually very severe and comes with nausea or vomiting.”

He adds that if your headache feels significantly different from your usual ones, especially if it’s persistent, worsening over time, or most intense after waking up, it’s worth seeking a neurological opinion.

Brain Fog vs. Brain Tumor-Linked Cognitive Symptoms

Feeling mentally scattered, struggling to focus, or forgetting things easily? It could be burnout, but not always.

“Brain fog due to burnout is usually transient, affecting multiple domains and without any functional disability,” says Dr. Kumar. It’s often tied to sleep issues like delayed sleep initiation or fragmented rest.

On the other hand, “Cognitive disability related to a brain tumor may affect one or more specific cognitive domains, tends to persist, and comes with functional disability,” he adds. You may also notice seizures, limb weakness, or trouble with routine tasks.

Clumsiness and Loss of Balance: When It’s Not Just Fatigue

Occasional clumsiness may seem harmless, especially during hectic workweeks. However, if it progresses to frequent falls, a noticeable decline in coordination, or needing support for routine tasks, don’t ignore it.

Dr. Kumar advises, “See a neurologist if there’s physical disability, frequent falls, need for support in walking, or significant reduction in your day-to-day functional efficiency.”

These may point to disturbances in the brain’s motor control centers, possibly caused by a tumor affecting balance and coordination.

Sudden Mood Swings or Personality Changes? Take Note

Stress does affect mood, but a rapid and unexplained shift in personality could be neurological. “Sudden personality changes, if persistent for a few days to weeks, suggest early features of a brain tumor,” says Dr. Kumar.

So, if someone who’s usually calm becomes irritable, withdrawn, or impulsive with no clear reason—and these changes don’t go away, it’s time for a deeper evaluation.

Vision and Speech Fluctuations

Blurred vision, slurred speech, or trouble finding the right words after a long day might seem like signs of tiredness. But if these symptoms come and go—or worsen—don’t brush them off.

According to Dr. Kumar, watch out for “faster reaction or impulsive behaviour, neck and back pain, early morning back stiffness, fluctuating vision or speech issues, and disturbed sleep patterns.” These are neurological red flags that demand attention.

Listen to Your Brain

The key message this World Brain Day is simple: Don’t ignore what your brain is trying to tell you. While stress is real and widespread, persistent or unusual symptoms—especially if they’re affecting your daily life—deserve a professional checkup.

As Dr. Kumar sums it up, “Early detection can significantly improve outcomes in brain tumors. When in doubt, get it checked out.”

We often think of sleep as just giving rest to the body and mind, but for children, it is anything but passive. Behind closed eyelids, their brains are buzzing with essential activity like building memories, managing emotions, and growing in every sense of the word. On World Brain Day, we turned to experts to know if sleep is really the ultimate secret sauce for a child’s brain and body development.

What Happens in a Child’s Brain While They Sleep?

“Sleep is not merely a time of rest for children,” explains Dr. Puja Kapoor, paediatric neurologist and co-founder of Continua Kids. “It is a critical period during which their brain grows, repairs, and develops.” She says that while it may seem like kids are just recharging, what actually unfolds is a complex neurological process.

When we sleep, our brain processes and stores everything we have done during the day as memory. "If we do not sleep well, our experiences do not consolidate into memory, and children may experience brain fog, irritability, and reduced learning capacity," she explains.

According to her, this reformatting helps the brain function better the next day. “Without this rest, children may become anxious, irritable, and less capable of absorbing new information or coping with day-to-day tasks,” she adds.

Spot the Signs: Is Your Child Getting Enough Sleep?

Dr. Kapoor lists the tell-tale signs of sleep deprivation: poor attention, emotional instability, hyperactivity, and trouble understanding or following instructions. And it is not a one-size-fits-all situation. “Newborns require around 16–18 hours of sleep; toddlers between 10–11 hours plus an afternoon nap; and older children around 8–9 hours of uninterrupted sleep,” she advises. For children under five, afternoon naps are essential for brain development.

Beware the Bright Screens and Late Meals

Modern habits can sabotage this much-needed rest. “Please end the use of TV or mobile phones at least 2 to 3 hours before bedtime,” warns Dr. Kapoor. “The light emitted from screens inhibits melatonin, the hormone responsible for sleep, from being produced, which disrupts sleep cycles.” She recommends creating a soothing bedtime routine with soft lighting, quiet music, cosy bedding, or even a lukewarm foot bath to help kids transition into sleep mode. And yes, dinner matters too. “Going to bed hungry can further interrupt their sleep,” she says.

Sleep and Brain Growth: The Pulmonologist’s Perspective

Echoing these views is Dr. Vikas Mittal, pulmonologist at Wellness Home Clinic and Sleep Centre, Delhi, who adds that the early years are a time of rapid brain development. “During sleep, the brain consolidates memories, processes new information, and strengthens neural connections,” he says. “It also supports emotional regulation and decision-making skills. Growth hormones essential for physical and neurological development are released during this time.”

Dr. Mittal also points to the long-term risks of poor sleep. “Sleep deprivation in children can result in inattention, memory problems, irritability, and hyperactivity symptoms often mistaken for attention-deficit/hyperactivity disorder (ADHD),” he explains. Ongoing lack of sleep could even reshape areas of the brain responsible for emotional control and academic performance.

Look Out for Red Flags

According to Dr. Mittal, warning signs of sleep deprivation include frequent mood swings, difficulty waking up, daytime sleepiness, or even clumsiness. These could point to not just fatigue but also underlying sleep disorders.

His solution? Structure. “Maintain consistent bedtime and wake-up times even on weekends,” he suggests. The sleep environment should be quiet, cool, and dark and definitely screen-free at least an hour before bed. “Encouraging calming activities like reading or listening to soft music can help signal the body that it is time to wind down,” he adds.

Treat Sleep Like a Daily Vitamin

Both Dr. Kapoor and Dr. Mittal agree that sleep is not just important; it is foundational. It impacts memory, learning, mood, physical growth, and even how well children adapt to their world.

Parents, take note: sleep is not optional. It is as essential as food, love, and education. By making bedtime a calm, screen-free, consistent routine, you are not just giving your child rest; you are investing in their future.

We all enjoy a nice, sweet treat every now and then. However, when we start overindulging in these desserts, that’s when it becomes a problem. It is a fact that sugar plays an important role in our daily intake, along with other whole foods that contain fiber, minerals, antioxidants as well as protein. But a big reason why we must consume it in moderation is because too much sugar can easily mess with your bodily functions.

A recent study, according to the Endocrine Society news release, suggests that even small increases in blood sugar, levels that aren't high enough to be considered diabetes, could negatively impact a man's ability to father children and his sexual function. The research indicates that even these minor elevations in blood sugar are linked to problems with how sperm move and with getting or maintaining an erection.

Blood Sugar's Impact Outweighs Age and Hormones

Surprisingly, this research found that these subtle changes in a man's blood sugar might affect his fertility and sexual health more significantly than the natural decline in hormone levels that comes with getting older. For a long time, it was thought that age and hormone levels were the main drivers of a man's declining sexual health. However, this study suggests that these changes are more closely related to small increases in blood sugar and other body changes tied to metabolism.

Lifestyle Choices Can Help

The good news is that men can take active steps to protect or even improve their reproductive health. Making healthy lifestyle choices and getting appropriate medical care can make a big difference. This means that men have the power to help their bodies stay healthy in ways that support their sexual and reproductive well-being. Simple habits like eating a balanced diet, exercising regularly, and losing any extra weight can help keep blood sugar levels in a healthy range.

To understand these effects, researchers followed a group of healthy men over several years. The study started in 2014 with 200 men, ranging in age from 18 to 85, and continued to track them until 2020. By the end of the study period, 117 of these men were still participating. During this time, researchers carefully looked at various aspects of the men's health. They examined changes in their sperm quality, hormone levels, ability to have erections, and indicators of their metabolic health. This included checking things like their body fat levels (measured by BMI) and, importantly, their blood sugar levels.

Key Findings

As the years passed, the men's hormone levels and general sperm characteristics mostly stayed within normal ranges. However, a significant finding emerged: sperm movement and erectile function saw a decline in men whose blood sugar levels went up, even if those levels were still below what's considered the diabetes threshold. This threshold is typically measured by a blood test called hemoglobin A1C, with 6.5% being the point for diabetes. The study also observed that while testosterone levels didn't directly affect a man's ability to get an erection, they did seem to influence his reported sexual desire.

The researchers are hopeful that the information from this study will be valuable for doctors and their patients. They believe it can help create effective plans for men to maintain their sexual health. This research shows that it's within our control to support men's sexual and reproductive well-being, even as they age.

It's worth noting that these findings were first shared at a medical conference. Information presented at such meetings is considered early and should be confirmed through publication in a scientific journal after being reviewed by other experts.

Heartburn is often dismissed as an annoying side effect of a spicy dinner or a late-night snack gone wrong. But here's the thing: not every burning chest sensation is harmless—and sometimes, it’s your body waving a red flag.

For most, heartburn is a fleeting, mild annoyance. For others, however, heartburn can be an indicator of more dangerous diseases such as gastroesophageal reflux disease (GERD), Barrett's esophagus, or even precancerous signs of esophageal cancer. Being able to tell when to brush it off and when to go to the doctor can make all the difference.

What is Heartburn Exactly?

Heartburn—also known as acid reflux—is a burning pain in your chest, typically behind the breastbone. It usually moves up toward the throat and can leave a sour taste. As its name suggests, heartburn does not have anything to do with the heart. It occurs when stomach acid moves backward into the esophagus, which irritates its lining.

This happens due to a weakened lower esophageal sphincter (LES), which is a muscle band that should function as a one-way valve. In case this valve is unable to remain tightly closed, stomach contents such as acid leak upwards, resulting in inflammation and pain.

For most, symptoms occur after big meals, when reclining, or after consuming specific trigger foods. But not all heartburn is a sign of illness. The alarm goes off when it occurs frequently, happens often, or doesn't respond to lifestyle modifications and over-the-counter medicine.

Most Common Causes and Triggers for Heartburn

There is no single culprit for heartburn, but there are some typical suspects:

Diet: Fatty foods, spicy foods, citrus fruits, tomatoes, chocolate, peppermint, onions, and caffeinated beverages such as coffee and soda are frequent triggers.

Medications: Aspirin, NSAIDs such as ibuprofen, certain sedatives, and blood pressure medications can relax or stimulate the LES.

Lifestyle Factors: Smoking, alcohol use, and obesity or pregnancy increase pressure in the abdomen, pushing acid upwards.

Eating Habits: Excessive eating, eating rapidly, or reclining shortly after eating can all be factors.

If you've experienced heartburn more than twice a week for a few weeks, you might be suffering from GERD—a more severe type of acid reflux that requires medical assessment.

When It's More Than Heartburn

One under-talked-about but important chronic heartburn-related condition is Barrett's esophagus. It arises when the esophagus compensates for repeated exposure to acid by altering the cell type lining it. This sounds like the body defending itself, yet it puts one at increased risk for developing adenocarcinoma of the esophagus, a rare but fatal cancer.

The UK's NHS is currently piloting a programme to provide "heartburn health checks" to check for Barrett's esophagus. It is a quick sponge-on-a-string procedure in which the patient swallows a capsule that harvests esophageal cells that are sent to the lab for analysis. It's very non-invasive and potentially a game-changer in cancer detection early on.

As Professor Peter Johnson, national cancer director of the NHS, says: "For the vast majority of people who have long-standing reflux, these simple and fast health checks will give them reassurance. and for those who do discover that they have Barrett's esophagus, follow-up checks will be arranged at regular intervals."

When heartburn persists, don't grab the antacids—see your doctor.

When Chest Pain Is More Than Heartburn

Let’s not ignore the elephant in the room: chest pain could also be a sign of a heart attack. While heartburn and cardiac pain can feel similar, they’re not the same.

Here are some key differences:

If you’re unsure whether it’s heartburn or heart trouble, seek immediate medical help. It’s better to be safe than sorry.

What is GERD?

Gastroesophageal reflux disease (GERD) is what heartburn is when it becomes chronic. If left untreated, GERD itself can cause a number of complications aside from Barrett's esophagus. One complication is esophagitis, where chronic inflammation of the lining of the esophagus wears it down, even causing ulcers or bleeding. Eventually, scar tissue from this wear and tear can cause strictures—narrowing of the esophagus—and make it harder to swallow. GERD may also impact the lungs; when acid flows back into the breathing tubes, it can initiate asthma, chronic cough, or other respiratory symptoms. There's even some new research pointing toward a potential association between GERD and nontuberculous mycobacterial lung infections, but additional studies are necessary to validate such a correlation.

One hypothesis is that individuals with GERD inadvertently breathe in aspirated stomach contents during reflux—particularly if contaminated—and are at risk for developing lung infections. Acid inhaled into the airways can also exacerbate asthma and chronic obstructive pulmonary disease (COPD).

When to See a Doctor?

Don't guess when it comes to your health. It’s time to see a doctor if you’re experiencing heartburn more than twice a week or find yourself relying on antacids or acid reducers daily. Persistent symptoms like difficulty swallowing, the sensation of food being stuck in your throat, or a lingering cough or hoarseness shouldn’t be ignored. Unexplained weight loss and chest pain that doesn’t clearly improve with antacids also warrant medical attention. These might be more than just plain old acid reflux, so don't wait it out—have it checked.

Long-term proton pump inhibitor (PPI) use—popular acid-lowering drugs—can be problematic too, including nutrient malabsorption, fractures, or infections in the gut. If you take PPIs daily, discuss regular checkups and potential alternatives with your doctor.

Home Remedies That Might Actually Help Relieve Heartburn

Although meds are useful, lifestyle adjustments and folk remedies can provide relief as well.

Yogurt: Its smoothness can lubricate the esophagus and soothe irritation. Added bonus: it's a gut friend.

Bananas: Their alkalinity can counteract stomach acid, and they're chock-full of potassium.

Alginates: In some OTC products, alginates create a protective foam cover over stomach contents.

Apple cider vinegar: Some people swear by it (diluted in water), although there's limited research.

Milk or aloe vera juice: Can be temporarily soothing.

Beware, however—what is effective for one individual may cause symptoms in another. Trial and error, under physician guidance, is your safest choice.

Heartburn is prevalent—but not always harmless. Occasional bouts are generally nothing to worry about, but if they occur often, get worse over time, or are accompanied by new warning signs, don't ignore them. Your pain may be your body's way of telling you something serious is going on.
