The average human gets around three billion heartbeats in their lifetime. That’s all the more reason to care for your ticker. Plant-based diets filled with veggies, sipping tea, and practicing yoga are among some of the smart ways to prevent heart disease.
You probably already heard that the human body is made up of mostly water (55 to 60 per cent for adult women and men, respectively). What you might be surprised to find out is that fluid isn’t just in your skin, muscles, and organs, but your skeleton, too. In fact, water makes up nearly one-third of your bone mass.
If you claim to be afraid of bacteria, better think again. A 2016 study found that a man weighing 70-kilos has about 38 trillion bacteria, which is roughly the same amount of human cells, the researchers say. What’s more, the bacteria weigh nearly 250 grams in total.
There was a long-standing stat that a sneeze travels 161 km/h, but newer research found it’s not even close. Still, that achoo is rather impressive. A 2013 study in PLOS One found that a sneeze moves at the rate of about 16 km/h. Still, cover your mouth and nose to safeguard others from germs – and read this if you’re tempted to hold in a sneeze.
Pass the deodorant please: You have two to four million sweat glands all over your body, points out the International Hyperhidrosis Society. Most of these are the non-stinky kind located on the soles of your feet, your palms, and forehead and cheeks.
People are born with five million hair follicles, 100,000 of which are located on your scalp, notes the American Academy of Dermatology. And while many women might want long locks, hair grows faster in men than women.
The human body is mostly made up of four elements: oxygen, carbon, hydrogen, and nitrogen, accounting for 96.2 per cent of you. (Calcium and phosphorus are the other big players.) It’s amazing how those elements come together to help create a body that does truly impressive things each day, from fighting cancer to forming 20,000 thoughts.
You inhale and exhale without even thinking about it – to the tune of 17,280 to 23,040 breaths per day. And while it’s an automatic habit, it can bring big benefits.
Speaking of inhaling and exhaling, your lungs have a tough job – and maybe that’s why they’re so large. Depending on the source, experts estimate that the surface volume of your lungs can cover a badminton court or half a tennis court (some even say an entire tennis court). That’s a lot of lung!
You exhale more than hot air: Exhaling is one way water leaves your body. And the amount that comes out quadruples when you exercise. When you’re getting sweaty, you exhale about 60 to 70 millilitres per hour, research points out. Time to take an H20 break.
You probably don’t think much about your dribble, but you produce on average 640 millilitres of saliva a day. That’s a good thing since saliva plays an important role in washing away the nasties in your mouth. People with low saliva levels are more vulnerable to cavities and oral infections.
Give it up for your noggin. There are at least 100 trillion neural connections in the human brain, Discover magazine reports. Keep them all firing by following these brain-boosting habits. Whether you tutor others or learn to play an instrument, you can protect against cognitive decline and stay sharp for the long haul.
Plus, make sure you’re not falling for any of these human body myths, which could damage your health.
Ever wonder why you need to clip your toenails less often than your fingers? It’s because they grow at a snail’s pace. While fingernails grow 0.1 millimetres per day, toenails only grow one millimetre a month, according to the American Academy of Dermatology.
Magnifying mirrors are the worst for revealing every imperfection on your face, but even they can’t see just how many pores dot your features. Adults have about 20,000 pores on their face, per L’Oreal Paris.
Blood vessels are tiny, but line them all up and you’ve got something really big – really big. Your body boasts a network of 96,560 kilometres of blood vessels, notes the National Institutes of Health. One way to keep them healthy is by eating right.
For men wanting to know if they measure up, the average penis is 12.7 to 17.7 centimetres when erect, according to the Kinsey Institute. They also note that the average circumference is 10.16 to 15.24 centimetres. If you have diabetes, your risk for erectile dysfunction is three times higher compared to healthy males.
Salty, sweet, bitter, sour, and savory: Your tongue boasts 2,000 to 8,000 taste buds, and each has 50 to 100 taste receptor cells. (The number and location of these taste buds varies widely in each person.) That’s a huge opportunity to love every bite of food you eat.
Women are born with one to two million eggs in their ovaries. But you won’t continue making them throughout your life: A woman’s supply decreases throughout her years until menopause. As many as 500 mature throughout the reproductive years, with the rest being simply destroyed by the body.
As big as your brain is, it’s a mystery why you’re losing your keys all the time. The average human brain weighs in at about 230 grams. And it can do some pretty impressive things – even the average person can train themselves to remember hundreds of words or numbers – here’s how.
