**Importance of physical activity**

 **The London Bus Study**



In 1953, *The Lancet* published a groundbreaking study by Dr. Morris, an esteemed epidemiologist. This research provided fascinating insights into the health disparities among London transport workers. Dr. Morris meticulously analyzed the health records of many conductors and drivers employed by the city's iconic double-decker buses.


His investigation revealed a striking contrast between the two groups, particularly concerning cardiovascular disease. Conductors, who were required to ascend and descend the bus stairs throughout their shifts, climbed an impressive total of over 700 steps daily. This significant level of physical activity was linked to a dramatic reduction in the risk of cardiovascular issues. In fact, the study found that conductors experienced a 50 percent lower risk of heart disease than their fellow workers in the driver's seat.


This pivotal study rapidly gained prominence in the West, sparking a broader public awareness of the essential role of exercise in maintaining overall health. The findings underscored the immediate benefits of physical activity and its protective qualities against various metabolic diseases. As a result, people began to embrace the importance of regular exercise as a fundamental component of a healthy lifestyle.

Educates vs Obesity

  To the educated ones in the family (yes, you!) You’ve cracked exams, earned degrees, mastered tech, maybe even figured out how to invest in mutual funds… but when it comes to your own health — what happened?! 😅 Let’s be real. Even with all this education, we’re still reaching out for that extra spoon of sugar in chai, frying everything in oceans of oil, and treating exercise like it’s some optional subject we dropped in college. And yes, I get it — our education system never taught us the most important subject of all: FOOD . No one ever taught us how to read a food label — how to spot the hidden sugars , the sneaky salts, or the overload of oils and fats . No one explained what those complicated, chemical-sounding ingredients really mean. And definitely, no one showed us how to tell the difference between what’s nourishing our body… and what’s quietly harming it. But guess what? Now we do have access to this information — and as educated people, it’s our responsibility ...

"You eat healthy, you workout hard. But Do you "SLEEP" enough?"

  The One Thing You're Ignoring That's Wrecking Your Health – SLEEP Let’s be honest. We’re living in a world that treats sleep like a waste of time . Late-night work. One more episode. A few more reels. And just like that — 2 a.m. becomes our new normal. We do everything to stay healthy — eat clean, drink detox teas, join gyms… But we skip the one thing our body literally begs for every night . That one thing? SLEEP. 🧠 Your Brain Needs Sleep — Not Just Coffee Every night when you sleep, your brain goes into clean-up mode — flushing out all the waste and toxins from the day. No sleep? No clean-up. Result? You wake up feeling tired, foggy, forgetful, and cranky. Long-term? It can lead to anxiety, depression, and even memory loss. Sleep is not laziness. It’s maintenance . ❤️ Your Heart Breaks Without Sleep You may not feel it, but your heart works overtime when you don’t sleep enough. Your blood pressure stays high. Your stress hormones shoot up. Your body ent...
