Get a younger heart with 5 everyday habits that fit easily in your lifestyle
is a natural process that affects every organ in the body, including the heart. As people grow older, the heart often becomes less efficient, increasing the risk of
cardiovascular disease
. However, recent research suggests that this decline may not be entirely unavoidable. A new study has found that certain lifestyle choices, combined with new scientific understanding, could play a role in keeping the heart biologically younger for longer.
In a study published in Nature Materials, researchers from the Mechanobiology Institute in Singapore have uncovered a surprising factor in heart ageing: the extracellular matrix (ECM). This structural network of proteins and molecules surrounds heart muscle cells (cardiomyocytes) and helps maintain tissue integrity, transmit signals, and support cell repair.
Over time, the ECM becomes stiffer and loses elasticity, which can negatively affect heart cell function. Until now, most heart ageing research focused on what happens inside the cells. This study shifts attention to the ECM and how its condition may drive cellular ageing from the outside.

Reversing Heart Ageing Through Cellular Environment
To test the relationship between heart cells and the ECM, researchers created a lab model known as DECIPHER. This system allowed them to grow heart cells within environments that mimicked either young or old ECM.
The results were significant. Young heart cells placed in an aged ECM environment began to behave like old cells, showing reduced performance and flexibility. Meanwhile, older cells placed in a young ECM environment regained many functions typically seen in younger cells. These findings suggest that the environment around heart cells plays a more critical role in ageing than previously believed.
Assistant Professor Jennifer Young, who led the research, noted that while most studies focus on internal cellular changes, their work highlights the importance of what lies outside the cells. This could open new possibilities for treatments that target the ECM to slow or even reverse heart ageing.
5 Lifestyle Habits That Support a Younger Heart
While treatments based on ECM research are still being developed, there are practical steps individuals can take now to support heart health. These habits not only promote a healthy ECM but also reduce the risk of age-related cardiovascular decline:
Stay Physically Active
Engaging in at least 150 minutes of moderate aerobic exercise each week helps keep blood vessels flexible and supports ECM function. Activities like walking, cycling, or swimming, combined with strength training, are especially beneficial.
Get Sufficient Sleep
Aim for 7 to 9 hours of restful sleep every night. Poor sleep is linked to increased blood pressure, inflammation, and heart dysfunction—all of which contribute to cardiovascular ageing.
Avoid Tobacco and Limit Alcohol
Smoking and heavy alcohol consumption have a direct negative effect on heart health and ECM integrity. Steering clear of both can significantly reduce cardiovascular risks.
Manage Stress Effectively
Chronic stress can lead to hormonal imbalances and inflammation that affect both heart cells and their environment. Mindfulness practices, outdoor time, and relaxation techniques are valuable tools for stress reduction.
Eat a Heart-Friendly Diet
Nutritional patterns such as the Mediterranean or DASH diet, rich in vegetables, fruits, whole grains, and lean proteins, have been linked to reduced inflammation and better heart health. It's advisable to limit processed foods and sugary beverages.

Top US doctor warns of common habits that are silently harming the gut
Harvard-trained gastroenterologist Dr. Saurabh Sethi highlights common habits silently harming gut health. Eating too fast triggers bloating, while artificial sweeteners disrupt the gut microbiome. Skipping meals leads to insulin spikes, and sleep deprivation weakens the gut lining. Excessive painkiller use damages the digestive tract. Dr. At a time when we are constantly bombarded by food vloggers glorifying midnight junk food cravings and online wellness influencers pushing the so-called gut-detox drinks, a Harvard doctor is urging people to hit pause and pay closer attention to their everyday habits. Dr. Saurabh Sethi, a California-based gastroenterologist trained at Harvard and Stanford, has shared a list of common habits that are silently destroying gut health. The gut doctor said that these common habits could be wreaking havoc on your digestive system. Let's take a look. Eating too fast Life has gotten so busy that many people barely take the time to sit down and enjoy a meal. Rushing through meals has become more common. Though many won't understand the danger behind it, Dr. Sethi warned that this habit can affect gut health. He noted that eating too fast can trigger bloating and acid reflux. When you eat too quickly, you often fail to chew your food properly. This forces the stomach to work harder to break down food, which can lead to discomfort and strain on the digestive system. The fix? Take your time. Give yourself at least 20 minutes per meal to improve digestion and reduce symptoms. Turning to artificial sweeteners Dr. Sethi has warned against using too many artificial sweeteners. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Нов таблет с Android Pro 14 Murreice Купете сега Undo Artificial sweeteners like sucralose and aspartame, found in many diet sodas and sugar-free products, may seem harmless, but can disrupt gut health. These sweeteners can alter the gut microbiome and potentially cause inflammation and digestive issues. Limiting artificial sweeteners and opting for natural alternatives, such as honey, if your health condition permits it, would be a better option. Skipping meals and later overeating Irregular eating habits can cause more harm than you think. Amidst work deadlines and personal duties, people tend to skip meals throughout the day, and then overeat at night. The gastroenterologist has warned that this habit may lead to insulin spikes and also put undue stress on the digestive system. This irregular pattern of eating can also lead to weight gain and gut inflammation over time. Focus on eating balanced meals at consistent times, do not starve your body, or overwhelm it with excess food. Balance is the key. Not getting enough sleep (Pic courtesy: iStock) Among the many things people tend to sacrifice to squeeze in their personal or career goals is their sleep. However, sleep deprivation can wreak havoc on your health, especially the gut. A restful sleep provides the gut time to rest for the next day. Chronic sleep deprivation disrupts this process. Lack of sleep can weaken the gut lining and increase the risk of issues like leaky gut syndrome. Remember, sleep is non-negotiable. Aim for at least seven to eight hours of quality sleep nightly. Excess use of painkillers Most of us have the habit of popping painkillers every now and then. But it may be doing more harm than good. Dr. Sethi has stressed that excessive use of NSAIDs (Nonsteroidal Anti-inflammatory Drugs) can damage the gut lining. NSAIDs like ibuprofen, aspirin, naproxen, and diclofenac can cause irritation, ulcers, or even bleeding in the digestive tract over time. Remember, NSAIDs are helpful but should be used sparingly.

Top US doctor says one does not need liver detox, eating these vegetables daily does the job
Dr. Joseph Salhab highlights the importance of diet for liver health, recommending cruciferous vegetables like broccoli and leafy greens such as collard greens. These vegetables naturally boost Phase II detox enzymes, aiding the liver's detoxification process. Incorporating these foods, along with regular exercise, supports optimal liver function without needing detox supplements. The liver is not just the largest organ in the human body, it performs over 500 vital functions, including the digestion of proteins, mineral storage, bile production, and blood filtration. The liver really keeps your body running smoothly behind the scenes, and yet most of us barely give it a second thought until something goes wrong. Liver disease is on the rise, with many being diagnosed with non-alcoholic fatty liver disease (NAFLD). But taking care of liver health does not really require fancy supplements or extreme detox. What you eat can significantly impact your liver health. Dr. Joseph Salhab, a Florida-based gastroenterologist, has now shared a list of vegetables he eats to keep his liver in the best shape possible. 'You don't need a 'liver detox' or cleanse,' Dr. Salhab said in a video shared on Instagram. He shared a list of vegetables he eats and added, 'These veggies naturally boost Phase II detox enzymes within your liver. Your liver already detoxifies your body, and good nutrition helps it work at its best. It's because they're high in compounds like sulforaphane, which help induce Phase II enzymes' Cruciferous vegetables Cruciferous vegetables such as broccoli, broccoli sprouts, Brussels sprouts, kale, and cabbage can help improve liver function. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Upto 15% Discount for Salaried Individuals ICICI Pru Life Insurance Plan Get Quote Undo These vegetables contain sulforaphane, a compound that boosts Phase II enzymes. This compound has anti-cancer and anti-inflammatory properties. Eating these vegetables can provide a protective effect on the liver. A 2007 study also confirmed that consuming Brassica vegetables like cabbage increased the activity of phase II detoxification enzymes in the liver. You can incorporate these veggies several times a week for maximum benefit. Leafy greens (All Images Courtesy: istock) Eat your greens, especially leafy greens, if you want to boost liver health naturally. The gastroenterologist noted that leafy greens like collard greens, mustard greens, and turnip greens are excellent choices to improve liver function. These greens contain detox-active compounds that enhance liver efficiency. Swiss chard, which is lower in sulforaphane, however, contains other detox-supporting nutrients. He also suggests adding arugula and watercress, which can contribute to liver health by supporting enzyme activity. You can add watercress in salads, smoothies, or even eat it lightly sautéed. You can eat most of these vegetables raw or lightly cook them to preserve their nutrients. Avoid overcooking. You can add healthy fats like olive oil for better nutrient absorption. Along with a balanced diet, regular exercise has also been shown to improve liver function.

RDI scheme: Government aims to 'jumpstart India's R&D ecosystem'; offer low-interest funding for startups
This is an AI-generated image, used for representational purposes only. India's newly approved Research Development and Innovation (RDI) scheme, with a massive Rs 1 lakh crore corpus, is set to provide a major boost to private sector R&D and deep-tech startups by making long-term, affordable financing accessible for high-impact innovation projects, a senior government official said. The scheme, approved by the Union cabinet on July 1, is designed to ease funding constraints and foster a robust domestic innovation ecosystem. A senior government official cited by news agency PTI said that the RDI scheme is structured to help companies access long-term, low or nil-interest financing for high-risk, high-tech research projects. The initiative will also support equity-based funding for startups and facilitate the creation of a deep-tech Fund of Funds. The corpus will be managed through a Special Purpose Fund under the Anusandhan National Research Foundation (ANRF), with Rs 20,000 crore already allocated in the Union Budget for FY26. The government will provide a 50-year interest-free loan to the fund, which will further allocate capital to second-level fund managers, including AIFs, NBFCs, and Focused Research Organisations. The official further said that the aim is to help India "jumpstart its R&D ecosystem" by creating a mechanism where ministries can propose relevant technologies for inclusion under the scheme. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Secure Your Child's Future with Strong English Fluency Planet Spark Learn More Undo 'Any ministry that wants a technology included under the scheme can send a proposal to the department of science and technology,' the official added. The department of science and technology will act as the nodal agency for implementation and will issue detailed operational guidelines. These will include provisions to ensure effective capital recycling so that private sector RDI efforts continue to receive support over time. India currently spends just 0.65% of its GDP on R&D, significantly below the global average of 2.7%, and far lower than countries like Israel (6.3%) and South Korea (5%). According to officials, one of the key objectives is to change the perception in the private sector that R&D is a cost rather than an investment. Union minister Ashwini Vaishnaw said the scheme will also fund transformative, higher technology readiness projects, and assist in acquiring critical or strategically significant technologies. 'By addressing the critical need of the private sector for long-term, affordable financing, the RDI Scheme fosters self-reliance and global competitiveness,' he stated. The scheme will be overseen by multiple layers of governance. The governing board of ANRF, chaired by the Prime Minister, will provide strategic direction. An Executive Council under ANRF will approve project scopes and second-level fund managers. Meanwhile, an empowered group of secretaries headed by the cabinet secretary will periodically review the scheme's performance and recommend changes. Officials stressed that selected fund managers will include experts from industry, academia, finance, and technology sectors, ensuring that project evaluations remain independent and effective. Launched under the broader umbrella of Startup India , the RDI scheme adds another critical layer to India's ambition to become a global innovation powerhouse by 2047.
