There was a time when being in your 20s automatically meant you were healthy. Like, you didn’t even have to try. You could eat roadside momos at 11 pm, sleep at 2 am, skip breakfast, and still wake up feeling normal. Or at least that’s what we thought.
But now? I keep hearing about people in their early 20s having fatty liver, PCOS, high blood pressure, even borderline diabetes. And not just random cases. It’s becoming common. Almost boringly common. Scroll through Instagram and you’ll see reels about “gut health”, “cortisol face”, “insulin resistance” and what not. When did health issues become a Gen Z trend?
Honestly, I don’t think it’s one big dramatic reason. It’s small daily habits stacking up quietly. Like interest on a credit card bill. You don’t notice it at first, but suddenly the amount looks scary.
Our Bodies Are Moving Less Than Ever
Let’s be real. Most of us don’t move much anymore.
School used to mean actual playground time. Now it’s coaching classes, online lectures, assignments, and then Netflix. Even jobs are mostly laptop-based. Eight to ten hours sitting. Then we “relax” by lying down and scrolling.
I read somewhere that sitting for long hours can slow metabolism significantly, even if you work out for one hour. I’m not sure about the exact stat, but the idea makes sense. If your body is designed to move and you keep it parked like a car in a basement, obviously things will start rusting.
And no, going to the gym three times a week doesn’t cancel out a completely sedentary life. It’s like brushing your teeth once and then eating sweets all day thinking it balances out. Doesn’t really work that way.
Stress Is Not Just For 40-Year-Old CEOs Anymore
This one hits hard.
Our parents had stress too, obviously. But I feel like today’s stress is more constant. It’s not just about exams or jobs. It’s about comparison. Every single day.
You open social media and someone your age is earning in dollars, someone is getting married, someone is getting abs, someone is traveling to Bali. Even if you’re doing fine, your brain keeps whispering, “You’re behind.”
Chronic stress increases cortisol. Cortisol affects sleep, weight gain, blood sugar, even hormones. That’s why so many young people are dealing with PCOS, thyroid imbalances, anxiety-related digestion issues. It’s all connected.
I have a friend who eats clean and works out but still struggles with high BP. Doctor said stress is a major factor. He just laughed and said, “So I need to uninstall LinkedIn?” Maybe he’s not wrong.
Food Is Convenient But Not Always Real
Let’s talk about food. Because this one is obvious but we still ignore it.
Food delivery apps are a blessing and a curse. You’re bored, you order. You’re sad, you definitely order.
Processed food is everywhere. High sugar, high salt, low fiber. And the scary part is it doesn’t feel unhealthy. A cold coffee from a café feels harmless, but it can have more sugar than a chocolate bar. Protein bars are marketed as healthy but some are basically candy in disguise.
There’s also this trend of extreme dieting. One week keto, next week intermittent fasting, then detox juices. Our bodies are not experimental labs. They get confused. Hormones get disrupted.
Lesser-known fact, India is becoming one of the diabetes capitals of the world, and not just among older adults. Urban youth are increasingly being diagnosed with prediabetes. That should honestly scare us more than it does.
Sleep Is Treated Like It’s Optional
If I’m being honest, I’ve sacrificed sleep more times than I can count. “I’ll sleep tomorrow” is such a common line.
But sleep is not a luxury. It’s repair time for the body. When you sleep less than six hours regularly, it affects insulin sensitivity, appetite hormones, mood regulation. Basically everything.
And it’s not just about hours. It’s about quality. Scrolling till 1 am and then sleeping with your brain still overstimulated is not real rest.
There’s also blue light, late-night binge watching, gaming till sunrise. I saw a tweet saying, “We are the most sleep-deprived generation but also the most caffeinated.” It’s funny but also painfully true.
Alcohol, Smoking and the ‘Chill’ Culture
Earlier, unhealthy habits were kind of hidden. Now they’re normalized. Party culture, weekend drinking, even casual smoking or vaping is seen as cool or stress-relief.
But these things don’t care about aesthetics. Alcohol affects liver health, metabolism, hormones. Smoking impacts heart and lung health. And starting these habits in your early 20s means longer exposure over time.
What worries me is how early it’s starting. College students talking casually about liver detox supplements. That shouldn’t be normal at 19.
We Think We’re Too Young To Worry
Maybe the biggest reason lifestyle diseases are increasing among youth is simple denial.
We assume serious health problems are for “later”. For 40-plus people. So we ignore warning signs. Irregular periods, constant fatigue, weight gain around the belly, hair thinning, anxiety, digestive issues. We call it normal.
But the body always gives hints before a full-blown disease happens. We just scroll past them like we scroll past ads.
And honestly, our healthcare approach is more reactive than preventive. We go to the doctor when something is already wrong. Rarely for routine check-ups. But prevention is cheaper. Think of it like servicing your bike before it breaks down in the middle of the road.
So What Now?
I’m not saying everyone needs to become a fitness influencer or eat boiled vegetables forever. That’s unrealistic.
But maybe small boring habits matter more than dramatic transformations. Walking daily. Sleeping on time at least most days. Eating home food more often than takeout. Managing stress in some way, even if it’s just journaling or talking to someone.
Youth should be the strongest phase of life, not the starting point of chronic illness.
Sometimes I feel we upgraded our phones, our internet speed, our careers. But we forgot to upgrade our relationship with our own body.
And the body keeps the score. Always.
