Longevity is about more than adding years to life; it's about adding life to your years. With an average life expectancy in the U.S. now standing at 77.5 years, medical and living conditions have so dramatically altered what we think we know about aging. But though genetics do have a part to play, they only account for 25% of lifespan variation. Lifestyle choices are where the real game changers are.

This article explores science-backed habits that transcend survival into helping you thrive. It discusses nutrition, mental health, and more to unravel the secrets of a longer, healthier, and fulfilling life.

Balance of Genetics and Lifestyle

Longevity simply put means living a long life. Life expectancy has dramatically improved over the years, from an average of 47 years in 1900 to over 77 years today. However, there is a catch- it is not only about living long but also living those years well.

According to research, only one-fourth of our lifetime is genetically determined, whereas the remaining part is created by our environment, diet, exercise, and lifestyle. This fact brings home a strong message- most of our lives are under our control, and so is our ability to have longer and healthier lives.

8 Habits of Highly Long-Lived People

A study that recently was released during a presentation at Nutrition 2023, an annual research conference in Boston, told of eight powerful habits leading to an immense improvement of life longevity. Using more than 700,000 data records on US veterans aged between 40 to 99 years old in its study, researchers reveal that embracing those habits around age 40 adds roughly 23 and 24 years of life among women and men, respectively. Such habits are as follows:

1. Physically activity .

2. Smoke less .

3. Maintaining an appropriate stress level.

4. Maintaining nutrition

5. Limit drinking.

6. Proper sleep hygine.

7. Having a positive social relationship with other people

8. Not using opioid drugs to solve their problems.

Among these, physical inactivity, smoking, and opioid use were the most harmful and increased mortality risk by as much as 45%. Stress, poor diet, excessive alcohol consumption, and lack of sleep followed closely, contributing to a 20%–30% increase in mortality risk.

What is Nutrition' Role in Longevity

What you eat directly influences your body's cells, impacting not only your lifespan but also your healthspan—the years you spend in good health. A diet rich in fruits, vegetables, whole grains, lean proteins, and healthy fats supports immune function, repairs cellular damage, and reduces inflammation.

On the other hand, foods that contain higher sugar and unhealthy fats would compromise the body's body defenses and increase the vulnerability to chronic diseases like diabetes, cardiovascular problems, and obesity.

The Mediterranean diet, emphasizing fresh produce, olive oil, fish, and nuts, has been consistently associated with longer lifespans and risks of chronic illness.

Role of Exercise

Exercise is one of the most effective ways to enhance longevity. Physical activity strengthens the heart, lungs, and muscles, improves balance, and maintains a healthy weight. These benefits collectively reduce the risk of life-threatening conditions such as heart disease, stroke, and diabetes.

Besides the physical benefits of exercise, it also works to improve mental health. Doing yoga, swimming, or even brisk walking boosts mood, reduces stress levels, and helps in enhancing sleep quality, all which contribute to a longer life.

Scientific evidence has shown that even if one engages in 30 minutes of daily movement, it can prolong life span and significantly improve overall wellness.

Stress Management and Social Connections

Stress is part of life; however, chronic stress becomes a silent killer. Chronic stress causes an elevation in cortisol, which triggers inflammation, suppressed immune response, and risk for chronic diseases such as hypertension and diabetes.

The transformation for fighting stress comes through such techniques as mindfulness meditation, deep breathing, and exercise. Equally important, though, are positive social relationships. Consistent evidence from studies indicates that strong social ties have a relation to better mental and physical health outcomes. Through family, friends, or the community, meaningful connections mitigate against stress and loneliness for a longer life.

Sleep

Sleep is the body's healing time. Poor sleep hygiene is known to disrupt hormones, weaken immunity, and compromise cognitive function, accelerating the aging process. Therefore, it is essential for the quality of rest achieved through consistent sleep schedules and the creation of a pre-bedtime routine that leads to a calming effect with little screen time before getting to bed. Experts maintain that adults need 7-9 hours of uninterrupted sleep per night to support optimal health and longevity.

Alcohol and Opioid Use

While moderate alcohol consumption—such as an occasional glass of red wine—may have health benefits, excessive drinking can cause liver disease, addiction, and premature death. Opioid misuse is still a major public health crisis with far-reaching implications for individual health and societal well-being.

The bottom line? Moderation is the key, and seeking professional help for substance use disorders can be life-saving.

Why Striving for a Quality Life Matters

Adding years to your life is one thing, but longevity means making sure those years are lively, meaningful, and full of purpose. The habits backed by science listed above form a roadmap to achieve that balance.

From a nutrient-rich diet and being active to managing stress and nurturing relationships, small, consistent changes can yield profound results. Take charge of your health today-not just to live longer, but to live better.

Because every choice you make shapes the legacy of your life.

Eight Modifiable Lifestyle Factors Associated With Increased Life Expectancy Among 719,147 U.S. Veterans. Nutrition. 2023

Atenolol is widely prescribed for conditions such as high blood pressure and irregular heart rhythms. While it is suitable for many adults, some people need to be especially careful before starting the beta-blocker.

NHS guidance highlights that certain medical conditions and life stages mean a doctor should be consulted first. This includes people with low blood pressure, Raynaud’s phenomenon, or asthma, among others.

Who Should Be Careful Before Taking Atenolol?

The NHS advises speaking to a doctor before taking atenolol if you fall into any of the following groups:

• People who are trying to conceive, are already pregnant, or are breastfeeding
• People with Raynaud’s phenomenon, which can cause fingers or toes to tingle, become unusually pale, or turn blue
• People with metabolic acidosis, a condition where there is too much acid in the blood
• People with low blood pressure (hypotension) or a slower than normal heart rate
• People with lung disease or asthma
• People who have previously had an allergic reaction to atenolol or any other medicine

How Atenolol Works?

According to official NHS advice, atenolol works by slowing the heart rate, which helps the heart pump blood around the body more easily. In addition to treating blood pressure and heart rhythm problems, it is sometimes prescribed to help prevent migraines and ease symptoms of anxiety.

The NHS notes: “Atenolol is only available on prescription. It comes as tablets or a liquid that you swallow. It can also be given by injection, but this is usually only done in hospital.”

Atenol: Medicines That May Interact With Atenolol

People who take other medicines should also check with a doctor before starting atenolol, as some drugs can affect how well it works or increase the risk of side effects. This applies not only to prescription medicines but also to herbal remedies, vitamins, and supplements.

You should speak to a doctor if you take:

• Other medicines for high blood pressure, as using them with atenolol can sometimes lower blood pressure too much and cause dizziness or fainting
• Medicines for irregular heartbeats, such as amiodarone or flecainide
• Medicines for asthma or chronic obstructive pulmonary disease (COPD)
• Medicines for diabetes, especially insulin. Atenolol can make it harder to notice the usual warning signs of low blood sugar. If you experience low blood sugar without symptoms, speak to your doctor and monitor your levels carefully, particularly after exercise or before driving
• Medicines for nasal or sinus congestion, or other cold remedies, including those bought over the counter
• Medicines for allergies, such as ephedrine, noradrenaline, or adrenaline

The NHS also states: “There’s not enough information to say that herbal remedies and supplements are safe to take with atenolol. They’re not tested in the same way as pharmacy and prescription medicines, and they’re generally not tested for how they affect other medicines.”

Atenolol Dosage And How Long Can It Be Taken?

The dose of atenolol you need depends on the condition being treated. For high blood pressure, the usual adult dose is between 25mg and 50mg once a day, but you should always follow your doctor’s instructions. Your medication packaging will also provide guidance on how to take it.

How long you stay on atenolol varies as well. For long-term conditions such as high blood pressure, it is often taken for many years and, in some cases, for life.

Furosemide is commonly prescribed in the UK to help manage conditions such as heart failure and high blood pressure. The diuretic medication is used by people of all ages, including children and infants. In 2024 alone, it was dispensed around 11 million times, making it one of the 20 most frequently prescribed medicines in the country.

Although it is widely used, doctors stress that furosemide must be taken carefully and in line with medical advice, as misuse can lead to serious health problems.

Furosemide: Why The NHS Is Warning Furosemide Users About Dehydration

To ensure safe use, the NHS has issued guidance urging certain people to speak to a doctor before taking furosemide. This is particularly important for anyone showing signs of dehydration, which can include feeling unusually thirsty, having a dry mouth, or noticing dark-coloured urine. Because furosemide increases urine output, it can raise the risk of fluid loss if not managed properly.

Who Should Speak To A Doctor Before Taking Furosemide?

The NHS advises the following people to consult a doctor before using furosemide:

• Anyone who has previously had an allergic reaction to furosemide or any other medicine
• Anyone with low blood pressure, also known as hypotension
• Anyone showing signs of dehydration, such as thirst, dry mouth, or dark urine
• Anyone diagnosed with liver disease
• Anyone living with diabetes
• Anyone who has difficulty passing urine
• Anyone diagnosed with Addison’s disease, a rare disorder affecting the adrenal glands
• Anyone diagnosed with gout

Furosemide: When Should Users Contact A Doctor Or Delay Treatment

Beyond these groups, the NHS also says furosemide users should seek medical advice if:

• You are due to have a glucose test
• You are scheduled for a scan or X-ray that involves an iodine-based dye being injected into your blood
• You are preparing for major surgery or a procedure that requires a general anaesthetic

How Furosemide Works And Why It Is Called A ‘Water Tablet’

Official NHS guidance explains that diuretics are often referred to as “water tablets” because they increase how often you urinate. This helps the body remove excess fluid.

“Furosemide is only available on prescription,” the NHS states. “It comes as tablets and a liquid that you swallow. It can also be given by injection, but this is usually only done in hospital.”

Medicines That Can Interfere With Furosemide

The NHS also warns that certain medicines can reduce how well furosemide works or increase the risk of side effects. This includes some commonly used over-the-counter treatments, such as paracetamol, co-codamol, and remedies for heartburn or indigestion.

Common Painkillers And Remedies To Use With Caution

Anyone prescribed furosemide is advised to speak to a doctor before taking:

• Medicines used to treat mental health conditions, including amisulpride, lithium, pimozide, or risperidone
• Medicines used to treat high blood pressure, or drugs that may cause low blood pressure as a side effect
• Sucralfate, a medicine used to treat stomach ulcers. Patients should leave around two hours between taking sucralfate and furosemide
• Non-steroidal anti-inflammatory drugs, known as NSAIDs, such as diclofenac, ibuprofen, or naproxen

Why Potassium Supplements Can Affect Furosemide?

Other medicines can also interfere with how furosemide works, including:

• Potassium supplements, steroids, or other diuretics that affect potassium levels
• Medicines used to treat, or that may cause, irregular heart rhythms, such as amiodarone, digoxin, disopyramide, flecainide, or sotalol
• Soluble paracetamol
• Soluble co-codamol

Certain Treatments For Heartburn And Indigestion

The NHS advises patients to tell their doctor if they are taking potassium supplements, as these can alter potassium levels in the blood and affect how furosemide works.

The health service also cautions against combining furosemide with herbal remedies or supplements. According to NHS guidance, there is not enough evidence to confirm they are safe to take alongside the drug.

Unlike prescription and pharmacy medicines, herbal products are not tested to the same standards and are generally not assessed for how they interact with other medications.

High blood pressure, also known as hypertension, is usually thought of as an adult health issue. But doctors are now raising serious concerns after a study published in The Lancet Child & Adolescent Health in November 2025 showed that rates of high blood pressure among children and teenagers have nearly doubled over the past two decades.

Blood Pressure In UK: The Lancet Study and Why Doctors Are Concerned in the UK

Hypertension has long been associated with people in their 30s and 40s, often linked to work stress and ageing. Today, however, shifts in daily habits and increasingly inactive lifestyles mean the condition is appearing more often in children and adolescents too. For years, young people were largely overlooked in discussions around blood pressure, and routine screening was rarely carried out. As a result, the true scale of the problem remained unclear. UK doctors are now calling for a nationwide testing programme to assess how widespread the issue is and to identify children who may need early support and treatment.

What Is Hypertension?

Hypertension is the clinical term for high blood pressure. It develops when the force of blood pushing through the arteries remains higher than what is considered healthy over time. Arteries are the blood vessels that carry oxygen-rich blood from the heart to the brain and the rest of the body. High blood pressure is often described as a silent killer because it can cause lasting damage without clear warning signs or symptoms.

Blood Pressure: How Is It Diagnosed?

Blood pressure is usually checked using a monitor with an inflatable cuff placed around the upper arm. The reading is shown as two numbers, measured in millimetres of mercury, written as one over the other. The top number, known as systolic pressure, reflects the force of blood when the heart beats and pumps blood around the body. The bottom number, called diastolic pressure, measures the pressure in the arteries when the heart relaxes between beats.

The definition of high blood pressure varies between countries. In the UK, a normal adult reading falls between 90/60 and 119/79. Readings from 120/80 to 139/89 are considered raised, while 140/90 and above is classed as high blood pressure. In the United States, readings between 130/80 and 139/89 are labelled stage 1 hypertension, with stage 2 beginning at 140/90.

Diagnosing hypertension in children is more complex. Blood pressure naturally changes as children grow and depends on age, height, and sex. Rather than fixed numbers, doctors diagnose high blood pressure when a child’s readings fall within the highest five per cent for others of the same age, height, and sex.

Blood Pressure In UK: Who Is At Risk?

High blood pressure is widespread, particularly among older adults. Around one in three adults in the UK and nearly half of adults in the US live with hypertension. Age plays a key role because arteries gradually lose flexibility and become thicker over time. Family history also matters, as genetics can increase risk. People from Black African, Black Caribbean, and South Asian backgrounds are known to face a higher likelihood of developing the condition.

Lifestyle choices also have a strong influence. Diets high in salt, being overweight or obese, lack of regular physical activity, smoking, excessive alcohol intake, and prolonged stress can all contribute to raised blood pressure.

What About Children?

In babies and very young children, high blood pressure is usually linked to underlying medical issues such as heart defects, kidney disease, or genetic and hormonal conditions. This form is known as secondary hypertension. Since the 1990s, however, rates of high blood pressure among children and adolescents have risen more than fourfold, reaching around six per cent. Poor diets, low levels of physical activity, and increasing rates of overweight and obesity are major factors behind this rise.

Why Is Hypertension Harmful?

High blood pressure can quietly harm the body for many years before symptoms appear. Constant strain on the blood vessels can lead to aneurysms, where weakened artery walls bulge and may rupture, sometimes with fatal consequences. The heart is forced to work harder, increasing the risk of heart failure. Damage to the inner lining of arteries can trigger inflammation and the buildup of plaques, making blood vessels narrower and less flexible. This restricts blood flow and raises the risk of chest pain, irregular heartbeats, and heart attacks.

The kidneys are especially sensitive to high blood pressure. Damaged blood vessels can stop them from filtering waste effectively, potentially leading to kidney failure that requires dialysis or a transplant. The eyes can also be affected, as their delicate blood vessels are prone to damage, causing bleeding, blurred vision, or even blindness.

When blood flow to the brain is reduced by narrowed or blocked arteries, it can lead to vascular dementia or mini-strokes. Severe cases may result in major strokes caused by clots or bleeding linked to long-term high blood pressure.

In children, hypertension can harm vital organs such as the heart, kidneys, and eyes at an early age. This makes early detection and treatment crucial to protect long-term health.
