Your heart works tirelessly every second of the day, but some everyday habits may be silently increasing your risk of heart disease. While many people focus on diet and exercise, several lesser-known lifestyle factors can also have a significant impact on cardiovascular health. Dr Sanjay Bhojraj, MD, Integrative Cardiologist, in his July 20 Instagram video, shared a list of habits that your heart would rather you give up sooner rather than later. Here’s what he recommends.

1. Nicotine (smoking, vaping, pouches)
According to Dr Bhojraj, all forms of nicotine, including cigarettes, vapes and nicotine pouches, can damage blood vessels, raise blood pressure and increase the risk of heart disease.
2. High blood pressure (Your heart is not a pressure cooker)
Uncontrolled high blood pressure forces your heart to work harder than it should, increasing the risk of heart attack, stroke and heart failure. Regular monitoring and lifestyle changes can help keep it in check.
3. Untreated sleep apnea
Ignoring sleep apnea doesn’t just affect your sleep quality. The condition can repeatedly reduce oxygen levels during the night, putting extra strain on the heart and increasing cardiovascular risk.
4. Insulin resistance/high blood sugar
Persistently high blood sugar can damage blood vessels over time and significantly raise the risk of heart disease, even before diabetes is diagnosed.
5. Ultra-processed foods
Highly processed foods are often loaded with excess salt, unhealthy fats and added sugars, all of which can negatively affect cholesterol levels, blood pressure and overall heart health.
6. Sitting all day (Ditch couch cardio this week)
A sedentary lifestyle has been linked to poor cardiovascular health. Dr Bhojraj encourages people to move more throughout the day instead of relying on prolonged sitting.
7. Less than 7 hours of sleep
Consistently getting too little sleep can increase inflammation, blood pressure and stress hormones, all of which may harm the heart over time.
8. Living in constant ‘fight-or-flight’ (Cortisol needs PTO)
Chronic stress keeps cortisol levels elevated, placing continuous strain on the cardiovascular system. Finding ways to relax and recover is just as important as regular exercise.
9. High ApoB/LDL particle burden
Elevated levels of ApoB and LDL particles can contribute to plaque buildup inside arteries, increasing the risk of heart attacks and other cardiovascular diseases.
10. Skipping strength training
Strength training isn’t just for building muscle. It also supports heart health by improving blood sugar control, metabolism and body composition.
11. Not eating enough fiber (Your gut ghosted your arteries)
A fiber-rich diet helps lower cholesterol, improves gut health and supports healthier blood vessels. Fruits, vegetables, legumes and whole grains are excellent sources.
12. Visceral belly fat
Unlike fat just beneath the skin, visceral fat surrounds internal organs and is strongly linked to heart disease, Type 2 diabetes and chronic inflammation.
13. Moderate to heavy alcohol use
Regular or excessive alcohol consumption can raise blood pressure, trigger abnormal heart rhythms and contribute to long-term heart damage.
14. Mouth breathing while you sleep (Your nose feels underappreciated)
Dr Bhojraj notes that habitual mouth breathing during sleep may be a sign of underlying breathing or sleep disorders that deserve medical attention.
15. Never taking recovery days (Even engines need maintenance)
Rest is an essential part of a healthy lifestyle. Constantly pushing your body without allowing adequate recovery may increase stress on the cardiovascular system and hinder long-term health.
While these habits are linked to heart health, not everyone will have the same risk factors. If you have concerns about your cardiovascular health or existing medical conditions, consult your healthcare provider for personalised advice and screening.
