Are you addicted to ‘chai'? It might be helping your heart only if you follow this rule
If your day doesn't truly begin until you've had that first steamy cup of chai and ends the same way, then you're not alone. For millions of Indians, tea is more than just a drink; it's a ritual, a mood, and sometimes even therapy in a cup.
But here's some garam-garam news: A new study says that having up to two cups of unsweetened tea a day could protect your heart and lower your risk of stroke and heart failure. But there's a little twist in the news: the health benefits vanish as soon as you add sugar or artificial sweeteners, meaning your favourite sweet, milky masala chai, the one that hits just right, isn't quite what the doctor ordered. So if you're serious about heart health, you may want to sip smarter.
According to the research study published in the
National Library of Medicine
on 'The role of tea in managing cardiovascular risk factors: potential benefits, mechanisms, and interventional strategies' and the study by Nantong University published in the
International Journal of Cardiology: Cardiovascular Risk and Prevention
, both studies shed focus on the benefits of drinking tea, but with a rule.
Tea: More than a drink? Stick to the daily cup cap for heart health
Tea is beyond just a beverage because of its chemical composition; it's a natural powerhouse packed with antioxidants, polyphenols, and unique plant compounds.
These include catechins and theaflavins that support heart health, reduce inflammation, and fight free radicals. Plus, tea polysaccharides help manage blood sugar and boost immunity. Whether green or black, every cup offers a gentle, science-backed health boost, especially when enjoyed without sugar.
Why unsweetened tea brings sweet success
If you love your daily cup of chai, here's something to steep on: keeping it unsweetened might protect your heart.
A large-scale study by Nantong University, published in the International Journal of Cardiology: Cardiovascular Risk and Prevention, followed over 177,000 adults in the UK for nearly 13 years. The findings? Those who drank up to two cups of unsweetened tea daily saw a
21% lower risk of heart failure
14% lower risk of stroke
7% lower risk of coronary heart disease
But there's a twist. These heart-health benefits were only found in tea drinkers who avoided sugar and artificial sweeteners. Once sugar was added, the protective effects disappeared.
Benefits of drinking tea, bitter
Tea has long been praised for its health benefits, and one of the most important is its ability to support healthy lipid (fat and cholesterol) levels in the body (NLM).
Lowers bad cholesterol (LDL)
: Compounds like catechins in green tea and theaflavins in black tea have been shown to reduce LDL cholesterol levels. They work by lowering cholesterol absorption in the gut and helping the body eliminate fats more efficiently through bile acid excretion.
Improves fat metabolism
: Tea enhances the body's natural fat-burning processes. It activates antioxidant enzymes that reduce oxidative stress and helps manage triglycerides and total cholesterol when paired with supplements like ginger or fish oil.
Greater benefits for women
: Some studies show that women aged 20 to 48 may get even more benefit from tea's antioxidants compared to those from vitamins when it comes to reducing fat-related damage in the body.
Works better with support
: While tea alone can help, combining it with other interventions—like healthy eating, supplements, or medication—can lead to stronger improvements in blood lipid levels.
Helps lower high blood pressure
: Hypertension (high blood pressure) is a major risk factor for heart disease. Studies have shown that long-term tea consumption, especially in moderate amounts, can help reduce both systolic and diastolic blood pressure by 2–3 mmHg, particularly in older adults.
Prevents hypertension over time
: A large study in Taiwan found that people who drank just 120 mL of tea daily for over a year had a significantly lower risk of developing high blood pressure. This suggests that even small, consistent amounts of tea can be beneficial.
Improves blood vessel function
: Tea is rich in antioxidants and polyphenols, which improve blood vessel flexibility (vasodilation), lower inflammation, and reduce oxidative stress—all of which contribute to healthier blood pressure levels over time.

Why are young, active adults facing fatal heart issues? The silent cardiac crisis striking healthy youth
It used to be rare—almost unthinkable. A 25-year-old collapsing in the gym, a 30-something IT professional dying in his sleep, a teenage athlete suffering cardiac arrest mid-game. But today, these stories are no longer shocking. They're becoming heartbreakingly routine. A wave of sudden cardiac deaths among young adults is sweeping across India and the world—and the big question is: Why? Explore courses from Top Institutes in Select a Course Category others CXO PGDM Project Management Design Thinking Public Policy Leadership Management Digital Marketing Degree Cybersecurity Healthcare Data Analytics healthcare MBA Artificial Intelligence Product Management Technology MCA Data Science Others Data Science Operations Management Skills you'll gain: Duration: 16 Weeks Indian School of Business CERT - ISB Cybersecurity for Leaders Program India Starts on undefined Get Details Skills you'll gain: Duration: 16 Weeks Indian School of Business CERT - ISB Cybersecurity for Leaders Program India Starts on undefined Get Details Experts are ringing alarm bells, and it's time we all listened. The Startling Shift: From Rare Tragedies to Daily Headlines According to a report from Times of India citing Dr. Girish B Navasundi, Senior Consultant in Interventional Cardiology at Apollo Hospitals , 'We're seeing people who appear healthy—students, professionals, even athletes—suddenly dying of cardiac arrest. It wasn't this common earlier.' So what changed? Why are people under 40—who should be in the prime of their lives—suffering fatal heart events? You Might Also Like: Shefali Jariwala's shocking death at 42: Apollo doctor explains why younger Indians are vulnerable to heart attacks and reveals silent symptoms The answer lies in a perfect storm of genetics, lifestyle stressors, and post-COVID complications—all converging to make young hearts more vulnerable than ever before. Cardiac Arrest ≠ Heart Attack: Know the Difference First, let's clear the confusion: A heart attack happens when blood flow to the heart is blocked—often due to clogged arteries. A cardiac arrest is electrical—your heart suddenly stops beating, and death can occur within minutes. While a heart attack might show signs like chest pain or discomfort, cardiac arrest often strikes without warning, leaving victims with little to no time to react. You Might Also Like: How being in love can actually boost your heart health, according to cardiologists The Silent Risks Lurking in Young Bodies Behind many cases of sudden cardiac death are undiagnosed conditions. Hypertrophic Cardiomyopathy (HCM): A thickening of the heart muscle that often goes unnoticed. Arrhythmogenic Right Ventricular Cardiomyopathy (ARVC): A rare genetic disorder affecting heart rhythm. Congenital Heart Defects: Present from birth but may only show symptoms later in life. According to the Cleveland Clinic, such heart abnormalities are now surfacing in people as young as 15. But there's more: COVID-19 has left behind a trail of cardiovascular complications. Even asymptomatic or mildly affected young people have reported myocarditis (inflammation of the heart muscle), which can lead to fatal arrhythmias. A Heart Under Constant Attack Poor diet and sedentary habits Overconsumption of processed foods and energy drinks Late-night work, screen time, and poor sleep Extreme or unsupervised workouts without rest Supplements and steroids used for quick fitness gains Add to this the invisible burden of chronic stress. As Dr. Navasundi explained: 'Mental and emotional stress raises blood pressure, disrupts sleep, inflames the body. The heart doesn't get rest—it's always in fight mode.' Stress has become so normalized among the youth that palpitations, anxiety, and fatigue are often ignored until it's too late. The Symptoms That Shouldn't Be Dismissed Cardiac arrests may be sudden—but the body often whispers before it screams. Watch out for: Shortness of breath Dizziness or blackouts Unexplained fatigue Chest pain or tightness Heart palpitations These symptoms are often misattributed to 'overwork,' 'gym soreness,' or 'just stress.' But in reality, they could be your heart crying for help. According to the Journal of the American Heart Association, the survival rate for out-of-hospital cardiac arrests is just 10%. That's why bystander CPR can double or triple survival chances. Sadly, India ranks low in CPR awareness. Knowing how to respond in those critical first minutes—before an ambulance arrives—can mean the difference between life and death.

Health facilities to display "Sugar and Oil" warning boards
New Delhi: Taking a leaf from schools and workplaces that have recently started displaying warning signs about high sugar and oil content in street food, the central government is planning to install these so-called 'oil and sugar boards' in hospitals, medical colleges and healthcare centres. The National Health Mission's (NHM) plan is part of a playbook to combat obesity and curtail unhealthy eating habits. An alarming recent report in the Lancet predicted obesity in India could jump from 180 million individuals in 2021 to 449 million by 2050, making it the country with the highest obesity burden globally after the US and China. Another Lancet study from 2022 revealed that India had 12.5 million obese children in 2022, a significant increase from 0.4 million in 1990. The Centre has asked the Indian Council of Medical Research (ICMR) to come up with an ideal nutrition diet for Indians and roll out a nationwide screening programme for measuring obesity among school children. 'Our nation is experiencing a rapid rise in obesity and associated lifestyle disorders, particularly in urban areas and among children. There is an urgent need to combat obesity and non-communicable diseases (NCD) through healthier habits and reduction in oil and sugar consumption," said a health ministry official in a letter to States/UTs, seen by Mint. "In view of this, States/UTs are requested to take proactive measures to ensure prominent display of 'oil and sugar boards' in health facilities such as Ayushman Arogya Mandir (Health and Wellness Centres), Primary Health Centres (PHCs), Community Health Centres (CHCs), District Health Centres (DHCs) and sub-divisional and district offices and medical colleges,' the letter added. Beyond the new warning boards, the health ministry is implementing a multi-pronged approach to combat unhealthy eating, focusing heavily on sensitization and education at the community and school levels. The ministry has specifically called for school teachers and children to be educated on healthy diets and reduced sugar and oil intake. This will be integrated into existing health screening and counseling activities. The initiative extends to adolescents, with a directive to sensitize peer educators and healthcare providers at 'Adolescent Friendly Health Clinics (AFHCs)'. To amplify this message at the grassroots level, the government plans to leverage community engagement platforms under the National Health Mission (NHM). This includes utilizing women's groups, other civilian groups, and community platforms to conduct discussions and practical demonstrations on healthy cooking and dietary habits. This 'comprehensive strategy' aims to embed awareness about healthy eating into various facets of daily life, from schools to community gatherings. The ministry is also asking for more cooperation with the education and women and child development departments to take this initiative even further. Dr Rajeev R. Jayadevan, public health expert and past president of Indian Medical Association (IMA), Cochin, said that hospital canteen signboards currently are no different from those at a restaurant, simply listing items and prices. But the government is now rolling out a significant behaviour change strategy to change that. These new boards won't ban popular cultural foods; instead, they will highlight the hidden sugar and fat within them. The next crucial steps, according to Jayadevan, is to expand this initiative nationwide, integrate healthier food options and could lead to substantial long-term health benefits. 'Increased awareness about the dangers of excessive sugar and salt intake will significantly reduce the disease burden in the coming decades.' Queries sent to the health ministry spokesperson remained unanswered.

Why Drinking Copper-Infused Water Every Morning May Benefit Your Health
Long before copper bottles became fashionable wellness accessories, Indian households understood their quiet power. In Ayurveda, copper holds a revered place, not just as a metal, but as a purifier, healer, and metabolic regulator. The tradition of storing water overnight in a copper vessel and consuming it in the morning is woven deep into our cultural fabric. Ayurvedic consultant Dr Poorvi Bhat highlights Tamra Jal's role in internal cleansing and recommends that "it should be consumed first thing in the morning." Diabetologist Dr Roshani Gadge adds that this copper-charged ritual can support digestion, immunity, heart health, and even skin repair. Here's how you can adopt this simple yet powerful practice safely. Health Benefits Of Drinking Tamra Jal Every Morning: 1. Detoxification And Gut Cleansing: Copper-infused water activates digestive enzymes, supports liver and kidney function, and promotes regular bowel movement. According to Ayurveda, this morning ritual, known as ushapan, helps flush toxins and prepares the gut for the day ahead. 2. Supports Heart Health: Tamra Jal may increase HDL (good cholesterol) and reduce LDL (bad cholesterol), thereby lowering the risk of blockages and regulating blood pressure. A simple copper glass might just become a heart-friendly habit over time. 3. Antibacterial Protection: A study published in the National Library of Medicine found that copper can destroy harmful bacteria like E. coli and Salmonella when water is stored in copper vessels for 8-10 hours. Tamra Jal is a natural purifier, especially useful in regions with inconsistent water quality. 4. Aids Diabetes Management: Dr Gadge explains that while copper doesn't directly regulate sugar levels, deficiency in the mineral can worsen symptoms like fatigue, poor healing, and inflammation. Tamra Jal may help support metabolic and cellular health when used consistently, though she advises against making changes without expert guidance. 5. Radiant Skin And Hair: Copper supports the production of melanin and collagen, enhancing skin quality, elasticity, and delaying greying. These cosmetic benefits are rooted in copper's role in cellular regeneration and antioxidant protection. How To Practise Tamra Jal Morning Ritual Safely: 1. Use Pure Copper Vessels Only: Choose food-grade copper bottles or tumblers. Avoid brass blends or lacquer-coated alternatives which may not be safe for storing drinking water. 2. Clean Regularly: Copper naturally oxidises, forming a green residue (patina). Dr Bhat recommends cleaning your vessel once a week with lemon and salt. But remember, lemon is strictly for cleaning, not consumption from copper. 3. Avoid Acidic Liquids: Never add lemon, tamarind, or vinegar to copper vessels. Acids react with copper, leading to leaching that may negatively affect digestion and immunity. 4. Practice Moderation: Too much Tamra Jal can cause nausea, abdominal discomfort, or even metal toxicity. Limit your intake to 2-3 glasses daily. The best practice is to check with an expert, especially if introducing Tamra Jal into your wellness routine. 5. Store Fresh Water Daily: Pour clean drinking water into the vessel at night, cover it, and consume it in the morning. Avoid leaving water stagnant beyond 24 hours, as freshness and microbial benefits can diminish. Note Of Caution: Not Substitute For Medication While Tamra Jal supports general well-being, it is not a replacement for prescribed treatment. Individuals with chronic illnesses, especially liver or kidney concerns, should speak to their doctor first. Final Thoughts: Rooted In Heritage, Backed By Insight Whether you are aiming for a gentle detox, better digestion, or radiant skin, Tamra Jal offers benefits that extend well beyond hydration. And in a world brimming with supplements and trends, it is comforting to know that wellness might still begin with something as simple as a copper glass, filled the night before.
