Studies have shown many benefits in drinking two cups of coffee every day. According to a study published in the American College of Cardiology magazine in 2022, there was a reduction in heart attack, diabetes and Alzheimer's disease in persons who consumed two cups of coffee. Anything taken in excess amount always comes with hazards.
According to a study published in one of the prestigious magazines of the World Stroke Organization,
people consuming more than four cups of coffee per day has increased risk of stroke
.
One of the largest studies on stroke in the world, the "INTERSTROKE", was conducted from 2007 to 2015. In this study, treatments and results were analyzed by various types of stroke in 26,950 patients across 32 countries in 5 continents.
Based on the results of this study, investigators of the InterStroke study concluded that high caffeine consumption of more than four cups per day was associated with higher risk of ischemic stroke. The problem of clotting in the brain blood vessels was 37 percent higher in patients who consumed more than four cups of coffee per day compared to those who consumed in moderation. However we have a good news here. Stroke risk was lesser in patients who consumed tea regularly.

They had 19% reduced risk of
ischemic stroke
compared to those patients who didn't consume tea. Brain bleeding risk didn't change significantly in all the subgroups. However, coffee addicts had higher BMI (obesity), poor diet and exercise compared to controls.
Coffee addiction
is harmful and may lead to increased risk of ischemic stroke. Tea consumption in various forms as green tea, lemon tea or milk tea is associated with reduced risk of stroke.
However coffee consumption in moderation (2cups or less per day) is associated with reduced risk of heart attack, Alzheimer's disease and diabetes.
Prevention is better than cure. Control your habits and lead a healthy lifestyle so that you can stay away from life threatening illnesses such as stroke.

Think Rs 5 lakh health insurance is enough? Here's why only a Rs 1 crore health customised cover is likely to be sufficient
Getty Images Hiking your insurance cover from Rs 1 lakh to Rs 1 crore does not imply that your premiums are also going to jump up significantly. In India's fast-changing healthcare landscape, medical costs are rising faster than income, inflation, and expectations. While advanced treatments are improving, they also bring growing financial pressure on individuals and families unprepared for emergencies. Most Indian households today are well aware of health risks from lifestyle diseases, the environment, and longer lifespans. Yet, financial preparedness, especially via health insurance, lags. We still treat insurance premiums as a commodity cost. We search for the lowest number, equating affordability with adequacy. In reality, the cheapest policy may be the most expensive mistake. Cracking the premium code in 2025 demands a rethink of what health insurance means, what it should deliver, and how we must align it with the new economics of look at the numbers. Over the past decade, the cost of hospitalisation, advanced procedures, and even routine diagnostics has climbed dramatically. Heart surgeries, cancer treatments, and critical care interventions now routinely cross the Rs.30-40 lakh mark. Cataract surgery, once considered minor, can now cost over 1 lakh in a top hospital. These are indicators of a structural shift in healthcare pricing, driven by better medical technology, global standards of care, and increasing demand. At the same time, medical inflation in India has consistently hovered at 13-14% annually—double the pace of general inflation and far beyond the wage growth for most Indians. Some years, it has surged as high as 20%. This is not a spike; it's a trend. Over the past decade, the cost of major medical procedures has surged. A kidney transplant that cost around Rs.5 lakh in 2013 now exceeds Rs.18 lakh. A heart transplant, in some cases, can cost up to Rs.34 lakh. In this context, insurance covers of Rs.3-5 lakh are no longer adequate; they reflect an outdated cost structure. If we continue to treat premiums as just another line item in our budgets, rather than a bulwark against financial distress, we will continue to be caught unprepared. Rising cost of critical care over the years Therefore, a Rs.1 crore health cover isn't a luxury; it's the new normal. It reflects the real cost of care today and anticipates the increasing complexity of medical interventions tomorrow. It is not just about critical illness. It's about diagnostics, consultations, follow-ups, mental health services, pre- and post-hospitalisation costs, and the growing expectation of quality care across every touchpoint. The comprehensive nature of healthcare today demands comprehensive financial coverage— and a rebalancing of what consumers consider 'adequate.'The good news is that increasing your health cover from Rs.10 lakh to Rs.1 crore doesn't mean your premium will go up 10 times. For a young couple in their mid-30s, a Rs.1 crore plan can cost around Rs.2,000 to Rs.2,500 per month— only about 10-15% more than a Rs.10 lakh policy, but with much stronger protection. The urgency of higher coverage is also reflected in how claim trends are shifting. In 2024-25, heart-related claims made up nearly 20% of total health insurance claims, up from around 10% five years earlier. Also, the average claim size for such cases has surged from Rs.4-5 lakh in 2019-20 to Rs.14-17 lakh today. Interestingly, the industry is evolving to match the shift. Insurers are designing more inclusive products, offering higher coverage limits, cashless treatments across wider hospital networks, and support services that extend well beyond hospitalisation. The market is responding not just to rising claims but to changing consumer alone are not enough. There is a growing responsibility for all stakeholders to reframe the consumers' approach to insurance. Premiums should be viewed as investments in resilience. Higher coverage should be encouraged. The long-term value of insurance must be placed front and centre, not just its annual price also a macroeconomic angle to this conversation. A financially unprepared population facing unpredictable health costs creates downstream effects: reduced productivity, increased household debt, and rising pressure on public health infrastructure. In a country where out-of-pocket healthcare spending still forms a major share of total expenditure, underinsurance is not just a personal risk; it's a systemic one. By helping more people access meaningful protection, we are safeguarding households and reducing the social costs of delayed or inadequate the premium code, then, is not about finding the lowest number. It's about asking the right questions: Will this coverage hold up five years from now? Can this policy support me through a complex medical episode? Does it enable me to act early and decisively when a health issue arises?India is on the cusp of a healthcare transformation, but for it to be inclusive, we must build financial resilience into the very design of that journey. That begins by treating the premium not as a price, but as a promise. The Auhtor is JOINT GROUP CEO, PB FINTECH

Niti brainstorms to prepare national brain health blueprint
New Delhi: Niti Aayog will soon come up with a blueprint on improving quality of brain health and recognising early signs of cognitive disorders and dementia. The move is aimed at preventing the rising cases of neurological disorders like Alzheimer's, Parkinson's, epilepsy and stroke, among others in the country.A senior government official, aware of the deliberations, told ET the work has been going on at the Aayog and concerned ministries for a year and is now in final stages."A meeting will be held on Tuesday to firm up the road map and we hope to submit the report to the government by end of June," the official said. Several rounds of deliberations have been held between the top officials of the Aayog, the Institute of Human Behaviour and Allied Sciences (IBHAS), the National Institute of Mental Health and Neuro Sciences (NIMHANS), the All India Institute of Medical Sciences and psychologists from the private sector. The idea is to develop a service model, on the lines of a brain health clinic, to help professionals identify people who have early cognitive decline and work with them to improve the quality of brain health and reduce their risk of dementia in the future. Besides, the experts will devise strategies to prevent and treat brain diseases by reviewing the gaps in providing treatment and suggest interventions. This is expected to work at all levels-primary, secondary and tertiary per Alzheimer's and Related Disorders Society of India, currently around 7.4% of Indians aged 60 and above are affected by dementia and this is expected to go up by 93% to 17 million by 2036 from the current 8.8 feel any initiative towards mental or brain health is much needed as it has long been ignored and will make a big difference in controlling the rising instances of neurological disorders. "Mental health needs a lot of focus, both on the preventive side as well as interventions. Anything we do either in terms of access, affordability, lifestyle changes or though interventions like digital and physical centres for early diagnosis would be of great significance in improving mental health across all age groups in the country," said Dr Samir Parikh, psychiatrist and director of department of mental health and behavioural sciences at Fortis Healthcare. As per the WHO, the burden of mental health problems in India is 2,443 disability-adjusted life years (DALYs) per 10,000 population and the economic loss due to mental health conditions, between 2012 and 2030, is estimated at $1.03 to the ministry of health and family welfare, 15% of India's adult population experiences mental health issues requiring intervention with urban areas having a higher prevalence of 13.5% compared with 6.9% in rural areas.
