We all have our moments where bad habits creep in—it’s just human nature. You’re fully aware that some behaviors can be harmful, but giving them up can be a challenge. Whether it’s indulging in late-night snacks, missing out on precious sleep, or enjoying that ‘innocent’ evening glass of wine, some habits can steadily undermine your health.
Not all vices carry the same weight in terms of risk, but certain habits pose significant threats to your well-being—especially as you enter your forties and beyond.
Four Habits That Drastically Affect Your Lifespan, According to a Cardiologist
Dr. Jeremy London, a board-certified cardiologist with over 25 years on the frontlines of heart health, recently shared his insights on TikTok about the top habits to ditch after you turn 40. Drawing on years of clinical expertise, he emphasizes that making these changes can lead to longer and healthier living.
1. Cut Back on Alcohol
While drinking may be a popular way to unwind, Dr. London strongly recommends significantly reducing or even eliminating alcohol. Regular consumption raises the risks of hypertension, liver issues, and heart complications, especially as you age and your metabolism declines. Minimizing—or cutting out—alcohol can greatly boost your heart and brain health.
2. Smoking and Vaping are No-nos
This point should be pretty obvious. “No vaping, no smoking,” advises Dr. London. Engaging in either activity significantly increases your chances of developing lung cancer, heart attacks, and strokes. Even vaping, frequently branded as a ‘safer’ alternative, harms blood vessels and raises inflammation levels. Quitting nicotine entirely is one of the best choices you can make for your longevity.
3. Don’t Neglect Your Sleep
When you’re youthful, it may seem fine to skimp on sleep to squeeze in work or social activities, but chronic sleep deprivation can be damaging over time. “Don’t sacrifice sleep for anything else,” Dr. London warns, admitting that he struggles with this issue too. Lack of sleep can lead to obesity, diabetes, and cardiovascular issues, and it negatively impacts your memory and mood.
4. Steer Clear of Toxic Relationships
Your social circle plays a bigger role in your health than you might guess. “Stay away from toxic people,” Dr. London advises. Negative or stressful relationships can raise cortisol levels—your body’s primary stress hormone—causing inflammation and deteriorating immune function. Instead, foster healthy connections with those who uplift and inspire you.
Dr. London’s approach is all about balance. He emphasizes making small but meaningful changes that protect your mind and body. “Surround yourself with loved ones, keep active, eat healthy, and prioritize good sleep,” he stresses. These straightforward, foundational actions might seem basic, but they are essential for enjoying a longer, healthier, and happier life.
