Sometimes the food you eat or the behavior you exhibit can be a sign of a deficiency and condition you may have. It is similar to when your stomach growls, which signifies that you are hungry. Other signs you may not know about are feeling fatigued when you do not drink enough water, and if you are experiencing a headache then you may need to eat etc. These things happen because they are connected in one way or the other, when you body lacks a specific nutrient you need throughout your day, it can manifest in different ways, let’s take iron for example.

Iron is like the delivery truck for oxygen in your body. It helps your red blood cells carry oxygen from your lungs to all your tissues. The Red Cross Blood Donation explains that when you don't have enough iron, your body can't make enough of these oxygen-carrying cells. This is called iron deficiency, and it can lead to anemia. You might feel very tired, look pale, or get dizzy easily. Headaches, cold hands and feet, and weak hair and nails are also common signs. Because iron is so vital for many of your body's functions, a lack of it can really affect your overall health and energy levels. It's important to recognize these signs and get checked by a doctor if you suspect you might have an iron deficiency.

What is Pagophagia and Pica?

Sometimes, your body sends strange signals when it's missing something important. One unusual signal for iron deficiency is wanting to eat ice, which doctors call pagophagia. This is part of a bigger problem called pica, where people crave things that aren't food. Other examples of pica are wanting to eat dirt, clay, or even starch. It's not just these things; some people crave things like coal, chalk, paper, or hair. While kids get pica more often, adults with low iron can have it too, even if they don't have anaemia. This weird craving is your body's way of trying to tell you something's wrong, even if it seems odd.

Eating things that aren't food can be risky. For example, eating dirt could expose you to harmful germs or heavy metals. Eating large amounts of ice might not seem dangerous, but it can sometimes hurt your teeth or gums. Ingesting non-food items can lead to serious problems like poisoning, where harmful substances build up in your body. It can also cause blockages in your intestines, which can be very painful and dangerous. Symptoms like stomach pain, bloating, feeling very tired, nausea, and diarrhea can signal that something is wrong. If you find yourself constantly wanting to eat ice or other non-food items, it's really important to talk to a doctor. They can help figure out why you're having these cravings and make sure you stay safe.

How Can You Make This Better?

If you're craving ice or other non-food items, it's important to see a doctor. They'll ask about your symptoms and might do some blood tests to check your iron levels. It's possible that your cravings are caused by iron deficiency, but they could also be related to other nutritional deficiencies or even emotional problems. Things like stress, obsessive-compulsive disorder, or developmental issues can sometimes cause pica. The doctor will try to figure out the root cause of your cravings. If it's an iron deficiency, they might suggest taking iron supplements or changing your diet. If it's an emotional issue, they might recommend talking to a therapist. Getting the right diagnosis and treatment is important for your health and well-being.

In today's fast-paced world, stress has become an unavoidable part of life. While short-term stress can help us stay alert and respond to challenges, prolonged or chronic stress can have a significant impact on brain health.

On the occasion of World Brain Day, it is important to raise awareness about how unmanaged stress can silently affect memory, concentration, emotional well-being, and overall quality of life.

How Chronic Stress Affects the Brain

When the body is under constant stress, it releases higher levels of cortisol, commonly known as the stress hormone. Persistently elevated cortisol can interfere with the normal functioning of the brain, particularly areas responsible for learning, memory, and decision-making.

Individuals may experience forgetfulness, difficulty concentrating, reduced productivity, irritability, anxiety, and disturbed sleep. If left unaddressed, chronic stress may also increase the risk of depression and other mental health disorders.

How to Protect Your Brain from Stress

The good news is that the brain has an incredible ability to recover when stress is managed effectively. Adopting healthy lifestyle habits such as regular physical activity, adequate sleep, mindfulness practices, balanced nutrition, and maintaining meaningful social connections can significantly reduce stress levels and protect brain function. It is equally important to recognize when stress becomes overwhelming and seek timely professional support.

Prioritize Brain Health

Brain health is just as important as heart health, and taking care of our mental well-being should never be overlooked. This World Brain Day, let us prioritize stress management as an essential part of a healthy lifestyle. By identifying the early signs of chronic stress and making positive lifestyle changes, we can preserve memory, improve focus, enhance emotional resilience, and ensure a healthier brain for years to come.

White sugar is widely known for its harmful effects on health. As a result, many people—especially those with Type 2 diabetes—turn to low- and no-calorie sweeteners such as aspartame, saccharin, and erythritol, believing they are a healthier alternative.

However, a new study published in Neurology, the medical journal of the American Academy of Neurology, has again suggested that higher consumption of certain artificial sweeteners may be associated with faster declines in memory and thinking skills over time.

The researchers stressed that the findings do not prove these sweeteners cause cognitive decline. Instead, they show an association, meaning other factors could also contribute to the observed pattern.

"Low- and no-calorie sweeteners are often seen as a healthy alternative to sugar. However, our findings suggest certain sweeteners may have negative effects on brain health over time," said study author Claudia Kimie Suemoto from the University of São Paulo, Brazil.

What Did the Study Find?

The study followed 12,772 adults in Brazil, with an average age of 52 years, for approximately eight years. Researchers examined the intake of seven commonly used low- and no-calorie sweeteners:

• Aspartame
• Saccharin
• Acesulfame K
• Erythritol
• Xylitol
• Sorbitol
• Tagatose

These sweeteners are commonly found in ultra-processed foods and beverages, including flavored water, soft drinks, energy drinks, yoghurt, desserts, and products marketed as low-calorie. Many are also sold separately for use in coffee, tea, cooking, and baking.

The researchers found that people with the highest total intake of sweeteners experienced a 62% faster decline in overall thinking and memory abilities than those with the lowest intake. This difference was estimated to be comparable to about 1.6 additional years of brain ageing.

Participants in the middle consumption group also showed a 35% faster decline, equivalent to approximately 1.3 additional years of ageing.

The association was especially strong among people with diabetes, who are more likely to use artificial sweeteners as sugar substitutes.

Stronger Link in Adults Under 60

Age also appeared to influence the findings. Among participants younger than 60, those who consumed the highest amounts of sweeteners experienced faster declines in verbal fluency and overall cognitive performance than those with the lowest intake.

Researchers did not observe the same association among participants aged 60 years and older. The study found that aspartame, saccharin, acesulfame K, erythritol, sorbitol, and xylitol were associated with faster declines in overall cognition, particularly memory. Tagatose was the only sweetener not linked to cognitive decline.

"While we found links to cognitive decline for middle-aged people both with and without diabetes, people with diabetes are more likely to use artificial sweeteners as sugar substitutes," Suemoto said. "More research is needed to confirm our findings and to investigate if other refined sugar alternatives, such as applesauce, honey, maple syrup or coconut sugar, may be effective alternatives."

Are There Any Limitations?

The researchers also acknowledged several limitations in study :

• It did not evaluate every artificial sweetener currently used in foods and beverages, so the findings cannot be applied to all sugar substitutes.
• Dietary intake was self-reported, meaning participants may have inaccurately remembered or estimated what they consumed.
• The study was observational, meaning it identified an association but cannot establish that artificial sweeteners directly caused cognitive decline.

Brain disorders are becoming one of India's fastest-growing public health challenges, said health experts ahead of Brain Day on July 22.

The experts highlighted that an ageing population, rising lifestyle diseases and limited access to specialist care are contributing to an increasing burden of conditions such as stroke, epilepsy, Parkinson's disease, dementia and multiple sclerosis.

Access Gap Delays Diagnosis, Treatment

Dr. Madhukar Bhardwaj, Director & Head of Department, Neurology, Aakash Healthcare, said neurological disorders have become one of India's most urgent healthcare concerns.

"Neurological disorders are no longer a concern of a small section of the population—they are one of the most pressing emerging healthcare challenges of our time. In a country as vast and diverse as India, with a rapidly ageing population, this is a matter of urgency. What makes the situation even more worrying is the lack of equitable access to care," he said.

According to the World Health Organization's Global Status Report on Neurological Disorders (2025), India faces a severe shortage of neurologists, with the neurologist-to-patient ratio nearly 80 times worse than in high-income countries, leaving specialist care concentrated in major cities.

Stroke Increasingly Affects Younger Adults

Experts also highlighted a worrying shift in disease patterns, with strokes increasingly affecting younger people. Dr. Bhardwaj said strokes, once considered a disease of older adults, are now being seen more frequently among people in their 30s and 40s, underscoring the need for greater awareness and prevention.

Lifestyle Diseases Driving Brain Disorders

Doctors identified uncontrolled hypertension, diabetes, obesity, smoking, chronic stress, physical inactivity and poor sleep as major contributors to the rising burden of neurological diseases.

Dr. Rajas Deshpande, Consultant and Head of Neurology, Jupiter Hospital, Pune, said many neurological conditions share common lifestyle-related risk factors.

"Controlling hypertension, diabetes, obesity, smoking and physical inactivity can significantly reduce the risk of stroke and vascular dementia. Prevention deserves as much attention as treatment because many neurological disorders share common modifiable risk factors," he said.

Early Diagnosis Can Improve Outcomes

Dr. Bhardwaj stressed that many neurological disorders progress silently, making early diagnosis critical.

"Whether it is stroke, epilepsy, Parkinson's disease or memory disorders, early diagnosis can significantly improve outcomes. Unfortunately, many patients seek specialist care only after the disease has advanced, either because symptoms are ignored or because neurological services are not easily accessible. Greater public awareness and timely referrals are essential," he said.

Brain Health Linked to Women's Reproductive Health

Experts also emphasized that brain health extends beyond cognition. Dr. Hrishikesh Pai, Consultant Gynecologist & IVF Specialist, Lilavati Hospital Mumbai and Fortis Hospitals Delhi & Chandigarh, said the brain plays a central role in regulating women's reproductive health.

"Brain health plays a critical role in women's reproductive health. The hypothalamus and pituitary gland in the brain regulate the hormonal signals that control menstruation, ovulation, and pregnancy," he said.

He added that chronic stress, neurological disorders, pituitary diseases and certain medications can disrupt hormonal balance, leading to irregular menstrual cycles, infertility and pregnancy-related complications.
