All the while, your heart beats steadily: 24 hours a day, seven days a week.

Yet how often do we actually think about it?

Consider what your morning might sound like:

Your alarm goes off, you glance at your phone, perhaps rush past breakfast, sit through hours of sitting, settle for a casual takeaway for lunch, work past your bedtime and finally throw yourself on the sofa by nightfall.

Usually, we only think about it when something goes wrong — when a health report brings up high blood pressure, when a doctor warns us about cholesterol, when our parent/guardian/friend has an issue or when we remember that, yes, that was six whole months ago that we resolved to start working out.

World Heart Day — on Sept 29 every year — is a fitting reminder that it can occur in a variety of places.

Not just in the hospital.

But in the kitchen, your office, the sofa, the road and your everyday routine, regardless of how hectic it might be.

Because heart health is a combination of the tiny things you might do or not do throughout the day that add up.

Why think about heart health before something goes wrong?

Cardiovascular diseases are the leading cause of death worldwide, and unhealthy eating, physical inactivity, tobacco use and harmful alcohol use are key behavioural drivers, with high blood pressure, high blood glucose, high cholesterol and overweight/obesity as major associated factors, according to the World Health Organization (WHO).

The challenge?

There are often no symptoms — and you might not even suspect that there is an issue.

For example, high blood pressure rarely presents any obvious symptoms, notes the WHO. The only reliable way to know whether you have it is to have your blood pressure tested.

Which means "I feel fine" is not always a reliable indicator of heart health.

Heart health is not about being morbidly afraid that you're going to die suddenly. It is about being aware of these risks before they get out of hand.

Two people: same routine, different choices

Let's imagine two individuals. Aarav and Rohan are both busy professionals.

They both have a sedentary job.
They both have a stressful life.
They both occasionally order a pizza.
They both lack the time or energy for a two-hour workout session.

In other words: they are fairly typical busy people with a fairly similar daily routine — aside from the fact that one takes care to maintain his heart health while the other does not.

They are both the same, apart from that one detail.

Let's explore what that detail might look like.

Aarav's routine

7:00 AM: Wakes up, has a glass of water.

7:30 AM: Has a healthy breakfast — rather than skipping it altogether.

9:00 AM: Starts working.

11:00 AM: Takes a break to stretch — rather than sitting through the entire day.

1:30 PM: Has a balanced lunch — rather than just highly-processed takeaway.

6:30 PM: Goes out for a walk or a workout.

8:30 PM: Doesn't binge-spend on a heavy meal.

11:00 PM: Goes to sleep — rather than lying awake staring at the ceiling.

Of course, Aarav is far from perfect in his routine.
He sometimes splurges on dessert.
He sometimes skips a workout.
He has stressful work weeks.
But healthy choices are a part of his daily life rather than an occasional detour.

Now, let's meet Rohan.

7:45 AM: Snoozes his alarm.

8:30 AM: Skips breakfast on the way to work.

10:30 AM: Drinks a lot of coffee.

1:30 PM: Eats a heavy lunch — at his desk.

3:00 PM: Drinks more coffee.

7:30 PM: Still sits at his desk.

8:30 PM: Tells himself he'll exercise tomorrow.

10:00 PM: Gets takeaway rather than cooking a healthy meal.

12:30 AM: Browses his phone before bed.

1:00 AM: Finally falls asleep.

Once again, Rohan is not a "bad" person by nature — and he doesn't deliberately set out to damage his health. He has the same busyness, same lifestyle pressures, same occasional pizza nights and same lack of exercise as many of us do.

But the small choices he makes — or fails to make — are the ones telling the bigger story.

Your heart knows what you eat.

You don't have to make every single meal healthy. It is about making your eating patterns overall as healthy as possible.

The WHO warns that diets high in salt, sugar and unhealthy fats are significant cardiovascular disease risk factors, noting healthy dietary patterns as a key strategy in prevention.

So, how can you modify your current eating patterns?

Eat more fruits and vegetables.
Incorporate healthy proteins into your meals.
Eat more minimally processed foods.
Be mindful of excessive salt.
Limit foods high in unhealthy fats.
Avoid highly-processed and high-sugar foods as everyday staples.
Watch your portions when consuming calorie-dense meals.

No, you don't have to give up your biryani or burgers — or even desserts — entirely. But your repeated patterns of eating say more about your heart health than any one meal ever will.

"I'll exercise tomorrow."

You don't have to become a serious athlete to get heart health benefits from working out. But you do have to get moving — and it doesn't always mean going to the gym.

Walking, cycling, swimming, dancing, playing sports and strength-training are all great ways to get active. Even standing up and stretching regularly can help.

According to the WHO, adults need at least 150 minutes of moderate-intensity aerobic physical activity throughout the week, alongside muscle strengthening on two or more days.

But if you're completely new to this, it doesn't mean you have to immediately sign up for a half-marathon. It can start out as simply moving more than you normally do.

Your heart doesn't care if you were busy.

"I didn't have the time" is perhaps one of the easiest reasons to skip exercise. You might have had deadlines, long commutes, family obligations — or you just didn't feel like it.

But the truth is: movement doesn't always require a full one-hour session at the gym.

It can be as simple as walking during a phone call or climbing the stairs when you're short on time. It can mean getting active during your lunch breaks, having a workout session at home or playing active games with your children. It doesn't mean turning every spare moment into a fitness class — merely making sure not to treat it as an excuse to sit.

Smoking is not a "small" habit.

If there's one major risk factor for heart disease that you have to think about quitting, it is tobacco.

Smoking and other tobacco use are major contributors to cardiovascular diseases, and the WHO strongly encourages quitting as a key risk reduction measure.

If you're a smoker, "I'll quit someday" can often become a very distant goal. If you use tobacco and want to quit, it's always a good time to speak to a healthcare professional about evidence-based cessation support.

Remember: quitting smoking is a process, and every step you take matters.

What about alcohol?

Alcohol is often talked about as a "lesser evil" — but it can be incredibly harmful to your heart health.

The WHO highlights harmful alcohol use as a key risk factor and notes its association with numerous health conditions.

So, while there aren't exact "recommended" limits for everyone, it's best to avoid excessive or harmful use, and, if you're considering drinking for heart health reasons, it's best to speak to a healthcare professional than rely on anecdotal evidence.

Stress is good... in moderation.

Stress often manifests in unhealthy ways: eating on the go, sleeping with your phone next to you, thinking about work during family time, never taking a break, constantly feeling as though you're behind and so on.

Managing it doesn't mean eliminating all stress from your life — it means finding ways to relax and unwind.

It can be as simple as going for walks outside without your phone, spending more time with loved ones, practicing relaxation techniques, taking breaks and maintaining hobbies.

Stress alone isn't a heart attack — but it can certainly contribute if left unmanaged.

Sleep is not a waste of time

There's somehow an idea that "only" five hours of sleep is fine, or that you'll "catch up" on the weekends, or that there's just too much work to get anything done.

But a pattern of insufficient sleep can also be counterproductive — and it's best to think of it as one of those things your body needs to function correctly.

Make sure you get enough restful sleep, ideally on a regular basis.
Maintain a healthy sleeping pattern and bedtime.
Limit screen time before bed, if possible.
Avoid using your bed as an office.
Make sure your sleeping environment is conducive to a good night's rest

If you have issues with sleep on a regular basis or experience symptoms such as loud snoring or excessive daytime sleepiness, it's best to speak to a healthcare professional.

Know your numbers.

It's never too early or too late to know your numbers — and what they mean for your heart health.

Depending on your age, family history and risk factors, it's important to know your:

Blood pressure
Blood glucose
Cholesterol
Body weight and waist measurement

High blood pressure rarely presents symptoms, and it's vital to keep track of it — just the same way you would with blood sugar. It can be a silent killer if ignored.

The same applies to cholesterol, so it's best to speak to a healthcare professional about what you should ideally aim for and how frequently you should get these checked.

Heart disease only affects older people.

Age is a risk factor, but it's by no means the deciding factor.

Having a family history of heart disease, engaging in tobacco use, a sedentary lifestyle, unhealthy eating patterns, high blood pressure, high blood sugar, abnormal cholesterol levels and overweight/obesity can all contribute.

This is why it's important to keep heart health in mind regardless of your age and to maintain healthy heart-habits throughout life — because these choices will directly impact your heart health in the long run.

A healthy lifestyle is not a perfect lifestyle

Aarav wasn't perfect in his habits, and neither was Rohan — but it was the patterns of what most of them chose that mattered more in the long run.

One meal out, one skipped workout and one busy week are not going to define your heart health — but a consistent pattern of such behaviours can eventually catch up with you.

A healthier lifestyle is not about being perfect in every choice you make but being better on average in most of them.

What would Aarav and Rohan look like in a year?

Let's go back to our two fictional characters.

Although Aarav did have occasional unhealthy habits, he was far more conscious of maintaining his heart health.

He continued to take those small steps: eating healthily most of the time, exercising moderately on a weekly basis and sleeping well on a nightly basis.

Meanwhile, Rohan continued to slide into an unhealthy pattern — mostly because one unhealthy choice rarely defines a person — but eventually, these habits caught up with him.

Aarav wasn't perfect — but he was far more prepared to take care of himself in the long run.

7 small things you can do for your heart this week

Forget the inspirational "new year, new you" speeches — here's a more realistic approach:

  • Take a walk for 20–30 minutes.
  • Have an additional serving of fruits or vegetables.
  • Check your blood pressure (if it has been a while and it is appropriate for you).
  • Take regular breaks from sitting and move around.
  • Be mindful of the amount of salt in your regular diet.
  • Avoid your phone a little earlier and get some sleep.
  • Think of something you could potentially incorporate next week

The point is not to complete a seven-day challenge — it's to find something you can keep doing as a habit.

Lifestyle habits are an important aspect of heart health — but that does not mean that you should wait around for symptoms.

A heart attack can present with a variety of symptoms, including chest pain or discomfort.

Other symptoms may include pain or discomfort that spreads to the arm, shoulder, jaw or back, nausea, dizziness, sweating or shortness of breath.

If these symptoms arise or if you believe that you or someone else may be having a heart attack, it is essential to seek emergency medical attention rather than trying to determine whether the symptoms will go away on their own.
