How to stay healthier in your 70s by starting in your 30s

By the time you reach your eighth decade of life, the chances are that you’ll probably be feeling weaker, stiffer, and perhaps a little less cognitively sharp than in your younger years. Your sleep patterns might have changed so that you feel drowsier in the evenings and then wake earlier. Most concerningly, going by population averages, it’s likely that you will be dealing with at least one chronic health condition.

Yet researchers, now more than ever, are convinced that this is not an inevitability. “Based on what we now know, most people could expect to live to 90 or even 95 in good health if they were to optimise their lifestyle,” says Eric Verdin, president and chief executive of the Buck Institute for Research on Ageing in California. “And that’s very far from where we are, where most people live to 65 or 70 in good health, and then become ill and suffer all the indignities of old age.”

While Verdin says that it’s never too late to improve your health at any age through making positive lifestyle adjustments, whether that’s exercising more, eating better or cutting back on alcohol, you will likely fare best if you start sooner. In particular, researchers have highlighted your 30s as a key decade when a number of physiological systems, whether that’s muscle mass and strength, bone density or metabolic regulation, begin to show the first subtle age-related changes.

“It does highlight this period as an important opportunity to reinforce behaviours that build long-term resilience,” says João Passos, a professor of physiology at the Mayo Clinic’s Kogod Center on Ageing, based in Minnesota.

To understand what might be possible, researchers studying the ageing process like to focus on groups of people who buck the ordinary trends. One example is masters athletes, individuals aged over 35 who still compete regularly in sporting competitions, whether that’s running, cycling or other sports, often continuing into their 60s and beyond.

Paul Morgan, a senior lecturer in nutrition and metabolism at Manchester Metropolitan University, notes that many of these athletes display a very different ageing trajectory to the rest of us, characterised by a higher peak in cardiovascular function and muscle strength and function, followed by a delayed decline. As a result, he says that many of them manage to avoid loss of mobility and independence for much longer in later life. “They have this additional reserve which acts as a protective barrier through the middle stages of life,” says Morgan.

We can all learn from this. To give us the best chance of ageing well, Morgan says that we should aim to hit the highest peak that we can in our 30s, particularly when it comes to aerobic capacity (the maximum amount of oxygen your body can use during exercise), flexibility, and muscle strength.

One of the biggest risks for anyone over the age of 70 is tripping and falling, which is linked to a loss of agility and a decreased range of motion in the joints. “I always see the muscle groups in the lower limbs that are responsible for locomotion as having the biggest role to play in maintaining independence, and with that, good health in later life,” says Morgan. “So that’s especially important to focus on.”

Playing sport is an excellent way to achieve this. Research has shown that taking part in racquet sports such as tennis or badminton has a consistent association with extended lifespan, while a 2025 Japanese study highlighted the benefits of cycling, with older adults who cycle regularly being less likely to need long-term care or die prematurely.

Running for more than 75 minutes per week has also been found to slow certain aspects of the ageing process, but you might want to think again when it comes to running marathons. There is some evidence that pushing your body to extremes can actually accelerate some aspects of biological ageing, although this remains less well understood.

On the other hand, one study found that as little as five minutes of moderate to vigorous physical activity per day can help slow brain ageing, and according to Aditi Gurkar, an assistant professor of medicine at the University of Pittsburgh in the US, we can all get some of the healthy ageing benefits through following relatively simple steps. “Even a brisk 15-minute walk after a meal can make a meaningful difference,” she says.

Building your brain’s reserve

Just as we can protect and strengthen our muscles and cardiovascular system in our 30s, we can also do the same for our brain. Maintaining good dental health through regular checkups, a good brushing routine, not smoking, and limiting intake of sugary foods can make a surprising difference.

This is based on numerous studies which have repeatedly linked the development of periodontal disease, a gum condition characterised by elevated inflammation, with a heightened risk of cognitive decline in later life. This is thought to be due to the chronic impacts of systemic inflammation on the brain.

Your 30s could also be the decade to begin reducing your alcohol consumption. Drinking alcohol is linked to changes in gene expression in the body which accelerate ageing. Alcohol is also a key disruptor of sleep, and Verdin highlights consistent sleeping patterns as being key for avoiding age-related brain shrinkage and lowering dementia risk in decades to come. This includes making sure you go to sleep and wake up at the same time every day, known as sleep regularity. Not only does sleep allow the body to focus on repairing cells, it also gives people the energy and motivation to pursue a healthy lifestyle.

“Even if you’re lacking sleep for one night, your metabolism changes, and your willpower to do all the things that are keeping you healthy goes away,” he says.

Because of the importance of maintaining a regular sleeping pattern, Verdin says he now uses an alarm clock each night – not to wake himself up, but to remind him to go to bed. “The reason for this is we’re circadian beings,” he says. “Our whole biology, from gene expression to metabolism is in synchrony with the 24-hour cycle, and so I tell people, going to bed at the same time each day helps your body to stay really well synchronised to all of this.” A good night’s sleep may not always be possible, however, as anyone raising young children in their 30s will know.

Finally, your 30s is probably a good time to begin taking nutrition a little more seriously. Verdin says that one of the best things we can do is to give our bodies more time during the day when we’re not actually eating, for example through intermittent fasting.

While many proponents of intermittent fasting recommend a so-called 16:8 split, where you fast for 16 hours of the day and compress your eating into an eight-hour window, Verdin says that we can achieve plenty of benefits through a more manageable 12:12 split. “Essentially when you’re fasting, that allows your body to focus not on digesting but on repairing,” he says. “I tell people, when you are eating, you are building. When you’re fasting, you are repairing.”

Consuming more fruit and vegetables at the expense of ultra-processed foods could also make a difference. Gurkar points to work that she and others have carried out showing that people who ingest higher amounts of dietary carotenoids – plant chemicals found in vegetables such as sweet potatoes and carrots, and fruits like mango and apricots – age more slowly, possibly because these chemicals can play a role in protecting our cells from a form of damage called oxidative stress.

Overall, Passos is convinced that the choices we make in early adulthood can have a lasting impact on how we age. He points to large studies which have tracked tens of thousands of people in the US for decades, such as the Framingham Heart Study and the Nurses’ Health Study, which reveal that people who maintain healthier lifestyles in midlife have lower risks of cardiovascular disease, cognitive decline and frailty – even decades later.

“By maintaining healthier behaviours in our 30s, we may prevent or delay subtle molecular and cellular changes that, if left unchecked, accumulate over time and contribute to functional decline in our 70s,” says Passos. “While I don’t believe that by doing this we can stop ageing, we can certainly shape its trajectory.”

While you may still feel somewhat invincible in your 30s, the steady tick of the ageing clock ultimately impacts us all. But if you cut out excessive alcohol, find a sport which you can keep playing into your latter years, set a regular sleeping pattern and give your body more breaks from constant eating, your heart, muscles, joints, and brain will all thank you in years to come.

Beyond Uniforms and Lunchboxes: Is Your Child Healthy and Ready for School?

By Dr. Mamata Bothra, Specialist Pediatrician and Neonatologist, International Modern Hospital, Dubai

With schools reopening on August 25, parents across the UAE are busy preparing uniforms, books, shoes and lunchboxes. But before the school bag is packed, it is worth asking one more important question: Is my child healthy and ready for the new academic year?

As a pediatrician and neonatologist, I encourage parents to use the remaining days before school as an opportunity for a simple health review. This does not mean carrying out a long list of unnecessary medical tests. Instead, it is about identifying any health concerns that could affect a child’s learning, energy, development or overall well-being.

Start with vaccinations and medical needs

Begin by checking your child’s vaccination record. Make sure all routine vaccinations are up to date and that no recommended doses have been missed. Parents should also speak with their child’s doctor about the seasonal influenza vaccine.

If your child has a chronic medical condition or requires regular medication, ensure prescriptions are current and that the school has the necessary medical information, medicines and emergency action plan.

A routine pediatric check-up can also be valuable, particularly if your child has not been assessed recently. During the appointment, the pediatrician can evaluate growth, height, weight, blood pressure, physical development, nutrition and general health.

It is also an opportunity to discuss concerns that may have been postponed during the holidays, including recurrent headaches or abdominal pain, constipation, frequent infections, breathing difficulties, snoring, fatigue, poor appetite or unexplained changes in behaviour and school performance.

Preventive pediatric visits should not focus solely on vaccinations. They also provide an opportunity to discuss a child’s learning, behaviour, development, emotional health and any age-appropriate screening needs.

Does your child need tests for iron or vitamin deficiencies?

Iron deficiency deserves particular attention because it can affect a child’s energy, concentration and neurodevelopment. However, this does not mean that every healthy school-aged child needs to undergo a large “vitamin panel” before returning to school.

The decision to perform blood tests should be based on the child’s age, diet, growth, symptoms and individual risk factors.

Children who follow restrictive, vegetarian or vegan diets, have poor nutrition, consume excessive amounts of milk, have a chronic illness or are not growing as expected may require further assessment. Persistent tiredness, pale skin, weakness and difficulty concentrating can also indicate the need for medical evaluation.

When testing for possible iron deficiency is clinically indicated, particularly in adolescents, a complete blood count and serum ferritin test may be useful.

Similarly, testing for vitamin D, vitamin B12 or other nutritional deficiencies should be guided by the child’s medical history, diet, symptoms and clinical examination—not performed routinely for every child.

Do not overlook vision and hearing

A child who cannot see the board or hear the teacher clearly may appear inattentive when the real problem is sensory.

Possible signs of a vision problem include squinting, sitting very close to screens, rubbing the eyes, experiencing frequent headaches, holding books unusually close, struggling to read, turning the head to one side or showing an unexplained decline in school performance.

For hearing, parents should watch for frequent use of the word “What?”, increasing the television volume, difficulty following instructions, failing to respond when called or a history of recurrent ear infections.

Not every concentration problem is an attention disorder. Before labelling a child as inattentive, we should first make sure the child can see clearly, hear properly and sleep well.

Dental health affects learning too

A dental check-up is worthwhile if your child has not visited a dentist recently, particularly if there is toothache, sensitivity, bleeding gums, persistent bad breath or visible tooth decay.

Dental pain can interfere with eating, sleeping, concentration and school attendance.

Parents should also remember that a school lunchbox does not need to become a travelling sweet shop. Encourage children to brush regularly with fluoride toothpaste and limit frequent sugary snacks and drinks.

Reset the body clock before school begins

If your child’s bedtime has gradually moved towards midnight during the holidays, do not expect them to fall asleep at 9pm on the night before school.

Start adjusting bedtime and wake-up time gradually before classes begin. School-aged children generally require nine to 12 hours of sleep each night, while teenagers usually need eight to 10 hours.

Insufficient sleep does not always appear simply as tiredness. In some children, it may cause irritability, hyperactivity, poor concentration, mood changes or behavioural difficulties.

Prioritise balanced food and hydration

A nutritious breakfast and balanced diet can help children begin the school day with energy and concentration. Aim to include a variety of protein, whole grains, fruits and vegetables while reducing highly processed food and sugary drinks.

Hydration is especially important in the UAE’s climate. Send your child to school with a water bottle and encourage regular drinking throughout the day rather than waiting until they feel very thirsty. Water should remain the main drink.

A practical back-to-school health checklist

Before August 25, parents should consider the following questions:

Vaccinations: Are all routine vaccinations up to date?
Growth: Is my child’s height and weight progressing appropriately?
Iron and nutrition: Is there a dietary risk or unexplained fatigue that requires assessment?
Vision: Can my child see the board and read comfortably?
Hearing: Can my child hear clearly and follow instructions?
Dental health: Is there any pain, sensitivity or untreated dental problem?
Sleep: Has my child’s routine returned to school timings?
Food and water: Is my child eating a balanced diet and drinking enough water?
Chronic conditions: Are medicines, prescriptions and school action plans updated?
Development and behaviour: Have there been changes in learning, concentration, mood or behaviour that require attention?

Parents do not need to panic or turn the back-to-school season into a medical examination marathon. The objective is not to find a problem in every child. It is to ensure that an existing concern does not go unnoticed.

A new uniform may prepare a child for the classroom, but adequate sleep, balanced nutrition, clear vision, good hearing, healthy teeth and timely medical care prepare that child to learn.

This year, before asking, “Have you packed your school bag?”, perhaps ask one more question:

“Are you healthy, rested and ready for the year ahead?”

Back to the Heat: Why Returning to the UAE Can Leave Holidaymakers Feeling Exhausted

Returning to the UAE after spending several weeks in a cooler destination can leave some travellers feeling unusually tired, sluggish or generally out of sorts. According to a family medicine specialist, this is often part of the body’s natural process of readjusting to extreme heat and humidity.

Dr. Renuka Ramasamy, Specialist in Family Medicine at International Modern Hospital Dubai, explains that spending time away from a hot environment can temporarily reduce some of the body’s heat adaptations.

“When someone spends a couple of weeks in a much cooler climate, some of the body’s adaptation to extreme heat can begin to diminish,” she says. “Heat acclimatisation influences how efficiently we sweat, regulate our core temperature and manage the cardiovascular strain caused by hot weather.”

These adaptations can start declining within days or weeks when a person is no longer regularly exposed to high temperatures. When they return suddenly to the UAE’s summer conditions, their body must work harder to maintain a safe and stable core temperature.

More blood is directed towards the skin to release heat, sweating increases and the cardiovascular system must compensate for the additional strain. As a result, some people may initially feel unusually tired, physically heavy, less energetic or generally unwell.

“It is essentially a period of re-acclimatisation,” Dr. Ramasamy explains. “Fortunately, someone who was previously accustomed to the UAE climate will generally readjust more quickly than a person experiencing this level of heat for the first time.”

Heat, dehydration and disrupted routines

The sudden change in temperature is rarely the only reason people feel unwell after returning from holiday. Heat, humidity, dehydration, poor sleep and changes to daily routines can combine to make the transition more difficult.

In hot and humid conditions, sweating and fluid loss increase. At the same time, high humidity makes it harder for sweat to evaporate from the skin, reducing the body’s ability to cool itself efficiently.

Even relatively mild dehydration can contribute to fatigue, headaches, dizziness and difficulty concentrating.

“Travel may also disrupt sleep, meal times, exercise habits and normal daily routines,” Dr. Ramasamy says. “People can arrive home already tired or inadequately hydrated and then immediately expose their bodies to considerable heat stress.”

Certain groups are more vulnerable to the effects of high temperatures. These include older adults, young children, pregnant women, outdoor workers and people undertaking strenuous outdoor exercise. Individuals with chronic medical conditions and those taking medications that affect hydration, sweating or temperature regulation should also be particularly cautious.

Give the body time to readjust

During the first few days back in the UAE, people should allow their bodies to gradually readjust instead of immediately returning to a demanding routine.

Drinking water regularly throughout the day is important, rather than waiting until intense thirst develops. People who are sweating heavily may also need to replace electrolytes. However, those with heart or kidney conditions, or who have been advised to restrict their fluid intake, should follow their doctor’s individual recommendations.

Restoring a regular sleep and meal schedule as soon as possible can also support recovery. Fruits, vegetables and other water-rich foods may help maintain hydration, while excessive alcohol consumption should be avoided because it can worsen dehydration.

Exercise should initially be lighter, particularly when performed outdoors. Strenuous physical activity should be avoided during the hottest part of the day, and both the intensity of exercise and the amount of time spent outdoors should be increased gradually as heat tolerance returns.

“The body needs time to readjust,” Dr. Ramasamy says. “People who are not fully acclimatised should reduce the intensity and duration of outdoor exercise during their first week back in a hot environment.”

When symptoms require medical attention

Although mild tiredness and reduced energy may be part of normal re-acclimatisation, people should not automatically dismiss more serious symptoms as a consequence of returning from holiday.

Significant dizziness, fainting, confusion, persistent vomiting, severe weakness or other concerning symptoms may indicate heat-related illness and require prompt medical assessment.

“It is important to distinguish normal readjustment from possible heat illness,” Dr. Ramasamy warns. “Severe or persistent symptoms should not simply be attributed to coming back from holiday.”

For most healthy people, careful hydration, adequate sleep, lighter exercise and gradual exposure to outdoor heat can make the transition back to the UAE climate safer and more comfortable.

NMC Speciality Hospital, Al Nahda successfully treats Rare case of Guillain – Barré Syndrome in an 11 – Month old Infant

Dubai, UAE – A multidisciplinary medical team at NMC Specialty Hospital, Al Nahda has successfully treated an 11-month-old infant diagnosed with Guillain–Barré syndrome (GBS), specifically acute motor axonal neuropathy (AMAN), variant, enabling the infant to make a complete recovery.

The infant, who was previously healthy, was brought to NMC Specialty Hospital after developing severe irritability and an inability to bear weight following a recent viral illness. Recognising that these symptoms could indicate a serious underlying neurological condition, specialists initiated a comprehensive assessment, leading to the diagnosis of acute motor axonal neuropathy (AMAN), a rare variant of Guillain–Barré syndrome.

Guillain–Barré syndrome is an autoimmune neurological disorder in which the body’s immune system mistakenly attacks the peripheral nervous system. While it can affect individuals of all ages, it is rarely reported in infants younger than one year often making diagnosis particularly challenging.

The case was led by Dr. Krupa Torne, Paediatric Neurologist, and involved close collaboration among experts from Paediatrics, Neuroradiology, Neurophysiology, Physiotherapy and Nursing. The coordinated efforts of the multidisciplinary team enabled a prompt diagnosis and immediate initiation of treatment with intravenous immunoglobulin (IVIG) therapy, which is considered one of the most effective interventions for Guillain–Barré syndrome when administered early.

“The rarity of Guillain–Barré syndrome in infants can make diagnosis difficult, as symptoms may initially be mistaken for more common childhood illnesses,” said Dr. Krupa Torne. “In this case, the early recognition of neurological symptoms, combined with rapid multidisciplinary assessment and treatment, played a crucial role in achieving an excellent outcome. It highlights the importance of maintaining a high index of suspicion for neurological conditions even in very young children.”

Following treatment, the infant was closely monitored and underwent physiotherapy to support recovery and mobility. Over the following weeks, the infant demonstrated steady neurological improvement, regaining strength and motor function.

At the eight-week follow-up appointment, the infant was able to walk independently and showed a completely normal neurological examination, marking a full recovery.

The successful outcome underscores the importance of access to specialist paediatric neurological expertise and integrated multidisciplinary care in managing complex and rare childhood conditions.

“This case reflects the strength of collaborative care and the advanced capabilities available at NMC Specialty Hospital, Al Nahda,” said Dr. Torne. “When specialists across disciplines work together seamlessly, we can deliver timely, evidence-based treatment that significantly improves outcomes for our youngest and most vulnerable patients.”

The infant’s parents expressed their heartfelt gratitude to the entire medical team, acknowledging the compassionate care, clinical expertise and unwavering support that helped their infant make a full recovery.

NMC Specialty Hospital, Al Nahda continues to provide comprehensive paediatric care supported by advanced diagnostic capabilities and specialised clinical expertise, helping patients with both common and complex conditions achieve the best possible outcomes.
