5 dangerous habits that make your body age faster, says cardiologist

Smoking and vaping

Cardiac surgeon and medical doctor Jeremy London says smoking and vaping are among the fastest ways to age the body. Toxic metabolites from these habits increase oxidative stress and damage DNA.

Oxidative stress means that cells suffer more damage. Over time, this can affect vital organs and overall health.

Quitting smoking can be difficult, but it is the best thing you can do for your heart. Key recommendations include:

• Identify your triggers — keep a journal for a few days to note when nicotine cravings are strongest
• Seek medical support — nicotine replacement therapy such as patches, gum, or prescription medications can ease withdrawal symptoms
• Build a support system — tell friends and family about your plan so they can help you avoid triggers

Sedentary lifestyle

According to the doctor, more frequent movement can help maintain physical activity capacity with age, reducing the risk of frailty. However, a sedentary lifestyle can have negative consequences over time.

In particular, the body’s ability to deliver nutrients decreases, and mitochondrial function (energy production in your cells) declines — both of which can accelerate aging.

Small changes can make a big difference:

• Movement breaks — set a timer every 45 minutes to stand up, stretch, or walk for just two minutes
• Change your habits — link physical activity to things you already do, such as short morning walks while listening to a podcast
• Rethink your commute — park farther from store entrances or take the stairs instead of the elevator

Ignoring chronic stress

When stress is not managed, it affects not only mood but can also have long-term effects on the body at the cellular level, making stress management essential for heart and overall health.

Persistent, uncontrolled stress can accelerate aging. It increases inflammation, alters DNA regulation, and shortens telomeres (protective caps at the ends of chromosomes associated with aging).

Stress management requires intentional effort and practice:

• Deep breathing — inhale for four seconds, hold for four seconds, exhale for four seconds
• Limit gadgets — take breaks from news and social media in the evening to give your mind rest

Lack of sleep

Prioritizing healthy sleep habits helps the body recover each night, supporting everything from energy levels to long-term heart health.

It is important to maintain a consistent sleep schedule — going to bed and waking up at the same time every day, even on weekends.

Keep the bedroom cool, dark, and quiet. Read a paper book or listen to calming music for an hour before bedtime.

Poor diet

Poor dietary habits and excess weight can increase inflammation, insulin resistance, and metabolic dysfunction.

Focus on a balanced diet for a sustainable and enjoyable approach to heart protection.

How to eat for heart health:

• Prioritize protein and fiber — they help you feel full. Include beans, lentils, lean meats, vegetables, whole grains, or nuts in every meal
• Practice mindful eating — slow down and focus on taste. Eating without TV or phone distractions can help improve satiety
