Heart disease is a major problem throughout the world. Being one of the top killers globally, doctors often urge people to understand the symptoms and early signs of heart issues. While there are many emergency treatments people go for when a health situation like a heart attack, stroke, or blockage arises, it is best to take preventative measures as the results are better when you catch the issue early.

When one says heart issues, people often picture a person feeling chest pains and heavy breathing. While there is one sign of deteriorating heart health, there are other more subtle signs as well. Here are some overlooked signs of heart health, according to the British Heart Foundation

Swollen Ankles Can Signal Heart Trouble

Swollen ankles or feet can be a quiet but important sign that your heart isn't working as well as it should. If your heart isn't pumping efficiently, blood can build up in other parts of your body, causing fluid to collect. While swelling can also happen from standing a lot or other health issues, ongoing or unexplained swelling, especially with breathlessness or tiredness, might mean heart failure or circulation problems. If swelling continues or gets worse, it's vital to get medical advice.

Stomach Pain: More Than Just Indigestion?

Sometimes, stomach pain can be a sign of heart issues, even though it's often mistaken for indigestion. Because these symptoms can feel like common stomach problems, they're often overlooked. If your stomach pain won't go away, happens when you exert yourself, or comes with breathlessness, tiredness, or sweating, it's important to see a doctor to rule out more serious concerns.

Unexpected Sweating Can Be a Red Flag

Sweating a lot without a clear reason, like heat or exercise, can be an early warning sign of heart problems. If you start to feel hot and clammy along with chest pains, you should get urgent medical help right away.

Arm and Leg Pain

Leg pain or cramps in your calves could signal peripheral artery disease (PAD), where blood vessels in your legs are narrowed or blocked. This type of pain, especially during activity, means less blood is flowing to your muscles. Having PAD can increase your risk of heart disease or stroke. If you have ongoing leg pain or cramping during activity, talk to a healthcare professional.

Arm pain can also be a key warning sign of a heart attack, often feeling like pain spreading from your chest to your arms. This can come with other symptoms like chest pain or shortness of breath. If you have unexplained arm pain with these signs, get medical help immediately.

Persistent Tiredness: A Sign Your Heart Needs Checking

Constant fatigue, especially when you've had enough sleep and haven't overdone it, can be an early sign of poor heart health. If your heart isn't pumping well, your muscles and tissues get less oxygen-rich blood, making you feel constantly tired or weak. This is often noticeable during everyday activities that used to be easy, like climbing stairs. If you're unusually drained or have low energy often, consider a heart health check. There are even home tests available that can help you understand your heart age and risk factors.

Palpitations and High Blood Pressure: Key Indicators

Frequent or severe palpitations (feeling like your heart is racing or fluttering) can sometimes be harmless, but they might point to an underlying heart condition or an abnormal heart rhythm. One common abnormal rhythm, called atrial fibrillation, can increase your risk of a stroke. Pay attention to these feelings, especially if they come with dizziness, chest pain, or shortness of breath, and seek medical advice to manage your heart health.

High blood pressure is one of the most important risk factors for heart disease. If your blood pressure is too high, it can damage your arteries. You can often get free blood pressure checks at pharmacies to help assess your heart health

Diet may seem like a secondary issue for many of us, but for athletes, it plays a very important role. The food they eat today could change the course of their game the next day. Athletes like tennis superstar Novak Djokovic have special diets that help them perform their best. Sharing the juices he drinks every morning in an interview; we get a glimpse of what goes into being a professional player.

Why Does A Diet Play An Important Role

Different sports require different types of diet, for example John Hopkins Medicine explains that a runner athlete must go for a carbohydrate rich diet as they must expend a lot of energy in an extended period of time, meaning they must sustain a uniform strain of energy to make sure they complete their run. On the other hand, judo or wrestler athletes must focus on a protein-based diet that will help them build muscles and strength.

For elite athletes, every little detail matters – from what they eat to how they train and recover. It can all make the difference between winning and losing. When it comes to fueling the body for success, Novak Djokovic stands out. With an astonishing 24 Grand Slam titles, he's the most successful male player in history, surpassing even legends like Rafael Nadal and Roger Federer, and he's still competing at the highest level.

What Does Novak Djokovic Eat?

Recently, in a TikTok clip with sports journalist Graham Bensinger, Djokovic revealed a surprising part of his daily morning routine. When asked about a typical day, he shared: "When I rise from bed, I start with warm water and lemon so I can help my body to detoxify and then I would have celery juice on an empty stomach." While this might sound a bit unusual to most people, Djokovic's drink choices are actually supported by some interesting science.

Science Behind the Sips

Warm lemon water is a fantastic natural source of Vitamin C. This vitamin is crucial for many bodily functions and significantly boosts your immune system. It's also a powerful antioxidant, helping to fight off harmful molecules called free radicals and keeping your cells healthy.

Drinking this first thing in the morning, as Djokovic does, can also be great for your digestive system. The Cleveland Clinic explains that it also helps us stay hydrated and is a great remedy for kidney stones, weight loss friendly, as well as filled with antioxidants like vitamin C, protecting your body from diseases.

Adding celery juice to the mix offers similar benefits. It's also rich in Vitamin C, along with Vitamins A and K, and essential nutrients like potassium, folate, and magnesium. For a tennis player like Djokovic, Vitamin K is especially important for strong bones, while the other nutrients help with muscle recovery and healthy blood flow.

Beyond the scientific benefits, Djokovic himself says these drinks give him mental clarity and a general feeling of energy, setting him up for a positive start to his day.

Even if you're not planning to follow the exact routine of a world-class athlete, staying hydrated is always a good idea. The NHS recommends drinking six to eight cups or glasses of fluid throughout the day.

Do We Need Detoxifying Juices?

As an addition to your diet, these can be helpful, however many people go on juice cleanses, relying solely on the juice for sustenance, which is not healthy for your body. A big selling point for juice cleansers is their supposed ability to "detoxify" your system. It's true that drinking more fluids can help your kidneys work better, and some nutrients can assist your body in getting rid of waste.

However, there isn't enough scientific evidence to show that juice cleanses or other "detox" diets actually improve your body's natural ability to remove toxins. Your liver and kidneys are incredibly efficient at detoxifying your body on their own, without the need for special juice regimens.

Back in 2023, a 64-year-old man experienced something weird. He had green hair growing on his tongue. Initially he was prescribed antifungal medicine, however, the treatment did not work on him. What he had was called a hairy tongue.

A Visit To Doc

The patient's tongue turned green about two weeks before he paid a visit to the doctor. This was shortly after he had completed a course of antibiotics from a gum infection.

What initially happened was a discoloration and doctors thought that it was a case of oral thrush, which is a fungal infection. As a result, he was prescribed antifungal treatment, however, this did not do anything. Rather, there was moss-like growths.

When doctors had a closer look, they realized that the man's filiform papillae, which are the tiny, cone-shaped bumps that cover the surface of the tongue and give its rough texture were longer than from a healthy tongue. Though there were no signs of injury or change in taste reported from the patient.

What The Case Report Said?

The case report was published in the New England Journal of Medicine, where physicians wrote, "A diagnosis of hairy tongue was made."

What is hairy tongue? Hairy tongue or lingua villosa is a benign condition that causes hair-like growths of various colors to sprout on top of the tongue, said the report.

These growths are filiform papillae that haven’t shed as they normally do through regular friction — such as from brushing with a toothbrush, using a tongue scraper, or eating solid, textured foods. Under typical conditions, these tiny projections grow to about 1 millimeter before falling off naturally, in a process called desquamation, similar to how skin sheds, according to the Cleveland Clinic.

When this natural shedding doesn’t occur, the papillae can continue growing—reaching lengths of up to 0.7 inches (18 millimeters)—which can result in a condition known as hairy tongue. According to the American Academy of Oral Medicine, it affects roughly 13% of people at some point in their lives, most commonly in men and individuals over the age of 65.

As these bumps elongate into hair-like strands, they begin to trap food particles, bacteria, dead skin cells, and other debris—leading to the discolored, furry appearance of a hairy tongue. According to the American Academy of Oral Medicine, the tongue may appear brown, white, green, or even pink, depending on the underlying cause and factors like mouthwash use or certain candies.

What Causes Hairy Tongue—And Why It Sometimes Turns Black or Green

In many cases, hairy tongue takes on a jet-black appearance, a condition medically known as lingua villosa nigra, or black hairy tongue, according to a recent case report.

Several factors can increase the risk of developing a hairy tongue—regardless of its color. These include consuming a soft-food diet, drinking excessive amounts of coffee, tea, or alcohol, smoking, dehydration, poor oral hygiene, and taking certain oral medications that alter the mouth’s microbial balance. Regularly brushing the tongue is one of the most effective ways to prevent the papillae from becoming elongated and discolored.

In the case report, doctors treated a patient who presented with a green-colored tongue. They advised him to gently scrub his tongue with a toothbrush four times a day and to stop smoking. At a six-month follow-up, the patient’s tongue had returned to a normal appearance—even though he continued to smoke, the report noted.

Aging is not a linear process as many people think it is. While your chronological age may say a certain number, the way you live could cause you to be biologically older. Our chronological age is based on the number of years we have lived; however, our biological age could be higher or lower, based on how healthy our lifestyle choices are.

As we know, till a certain age, our body keeps growing and then comes to a halt. Studies like the 2013 study published in the Neuropsychiatric Disease and Treatment journal explain that our brain’s development is not complete until the age of 25, especially the prefrontal cortex. Like every living being, if we are developing, we will eventually deteriorate as well. However, at what age does this deterioration begin?

A groundbreaking study published in Nature Medicine found that a simple blood test can reliably estimate a person's age by analyzing the levels of hundreds of proteins. This "proteomic clock" offers a fascinating insight: biological aging isn't a smooth, linear process. Instead, it appears to accelerate in distinct phases.

Key Ages of Accelerated Aging

The study identified three significant periods when aging seems to speed up, on average: around ages 34, 60, and 78. Notably, the research suggests that the average person begins to show signs of physical deterioration as early as 34 years old. Based on these findings, "adulthood" was categorized as 34 to 60 years, "late maturity" from 60 to 78 years, and "old age" from 78 years onward.

To build this "proteomic clock," the scientists collected blood plasma (the liquid part of blood) from over 4,200 healthy people, ranging in age from 18 to 95. They used the information from more than half of these people to create their "clock." This clock was then able to correctly guess the age of the remaining people in the study. What's even more impressive is that they could make accurate age guesses using just 373 of the almost 3,000 proteins they first looked at. They even found that they could get a decent guess with as few as nine key proteins!

The study also showed that people whose blood proteins made them seem biologically younger than their actual age also did better on tests that measured how well their brain and body worked.

What This Means for Our Future

These findings have significant implications. This research suggests the potential for a blood test that could identify individuals who are biologically aging faster than their chronological age. Such individuals might be at a higher risk for age-related health issues like cardiovascular problems, Alzheimer's disease, and osteoarthritis earlier in life.

Furthermore, this research offers hope for developing interventions that could potentially slow down this "proteomic clock," keeping people biologically younger for longer. While it may sound like science fiction, the same research team has previously shown that it's possible to rejuvenate an older mouse by infusing it with blood from a younger mouse, hinting at future anti-aging treatments.

The discovery that the first burst of accelerated aging occurs in early mid-life, around age 34, is particularly intriguing, as it's well before the typical onset of noticeable aging signs and related health problems.
