8 Lifestyle Changes That Add Years to Your Life

Genetics account for only about 20% of your health outcomes. The remaining 80% is shaped by lifestyle choices. Our preventive medicine team shares the eight evidence-backed habits that have the greatest impact on longevity and quality of life.

1. Move Every Day

Even 30 minutes of brisk walking daily reduces all-cause mortality by 35%. You do not need a gym — consistent moderate activity is more important than intense occasional exercise.

2. Eat More Plants

A diet rich in vegetables, fruits, legumes, nuts, and whole grains is associated with lower rates of cancer, heart disease, and dementia. Aim for at least 5 servings of fruit and vegetables per day.

3. Sleep 7–9 Hours

Chronic sleep deprivation is linked to obesity, depression, cardiovascular disease, and weakened immunity. Prioritise sleep hygiene: consistent bedtime, dark room, no screens 1 hour before bed.

4. Stay Socially Connected

Loneliness is as damaging to health as smoking 15 cigarettes per day. Strong social relationships reduce the risk of dementia and premature death significantly.

5. Do Not Smoke

Tobacco use causes 8 million deaths per year globally. Quitting at any age has immediate health benefits. Our hospital offers a free smoking cessation programme.

6. Limit Ultra-Processed Foods

Ultra-processed foods (packaged snacks, fast food, sugary drinks) are linked to obesity, Type 2 diabetes, and colorectal cancer. Cook whole ingredients as much as possible.

7. Manage Stress Actively

Chronic stress causes systemic inflammation and accelerated cellular ageing. Mindfulness, yoga, exercise, and hobbies all reduce cortisol and improve mental health.

8. Get Preventive Screenings

Many serious diseases are curable if caught early. Know what screenings are recommended for your age and gender — blood pressure, cholesterol, blood sugar, cancer screening — and stay up to date.
