Office stress, poor sleep and junk food: Habits your heart may not like

Cardiovascular risk is often shaped by routines that seem harmless on their own: hours at a desk, irregular sleep, convenience foods, chronic stress and the assumption that feeling well means being healthy. It is difficult to ignore the concern when you look at the numbers.
In 2023, cardiovascular diseases caused 19.2 million deaths globally, becoming the leading cause of death globally according to a 2025 analysis of the Global Burden of Disease data. The World Heart Federation’s 2024 country profile estimates more than 3.1 million cardiovascular deaths in India.

Still, we are increasingly practising certain habits which may not be heart-friendly.

Sitting for long hours

The problem is not with a desk job itself. The problem is that most of the day is spent sitting instead of moving. A 2024 WHO analysis found that 31 percent of adults worldwide, around 1.8 billion people, were not meeting recommended levels of physical activity, with inactivity hitting 45 percent in South Asia.

Bringing work stress home every evening

Heart disease doesn’t happen overnight from a stressful meeting. But chronic stress is a different thing. Long-term stress can affect blood pressure and increase the chances of unhealthy behaviours – overeating, smoking, drinking or inactivity. The 2025 hypertension guideline also identifies stress management as a part of cardiovascular risk reduction.

Scrolling at midnight

Sleep is more than just a time when the body switches off. A 2025 AHA scientific statement identified sleep duration, regularity, timing, continuity and quality relevant to cardiometabolic health. The average adult needs between seven and nine hours of sleep.

Eating ultra-processed food due to its convenience

When work runs late, packaged snacks and ready-to-eat meals can be an easy default. A 2024 BMJ umbrella review of almost 9.9 million participants found an association between higher exposure to ultra-processed foods and cardiovascular mortality, but the researchers rated the quality of evidence for this particular association as very low.

Weekend as a cardiovascular reset

You can’t undo five days of unhealthy routines with two days of overeating, heavy drinking and inactivity. The 2025 AHA/ACC hypertension guideline emphasises that alcohol intake is associated with increased systolic blood pressure, emphasising moderation and consistency rather than a weekend “reset.”

Assuming “I feel fine” equals “my heart is fine”

Perhaps this is the most dangerous assumption of all. Cardiovascular risk factors such as hypertension may be silent for many years. In India, the national NCD programme identified more than 1.11 crore people with diagnosed hypertension in treatment during January–June 2025, highlighting the extent of the condition that is being actively managed through the health system.

Perfection isn't needed for heart health. It requires pattern attention. Keep moving regularly. Guard your sleep. Eat fewer processed foods. Manage chronic stress. Think about alcohol and tobacco consumption.

Most importantly, know your blood pressure, blood sugar, cholesterol and other relevant risk factors – and discuss your individual cardiovascular risk with your doctor.
