[Did you know?] Fun Trivia Quiz About Health

You’re taller in the morning.

A person's height fluctuates depending on the amount of water contained in the intervertebral discs, the cushion-like tissues between the vertebrae. While lying down at night, the discs are not compressed and can absorb water more easily, making you tallest when you wake up in the morning. During the day, the effect of gravity on the body compresses the discs and slightly reduces their water content, so it is said that your height becomes a bit shorter by evening.

about 100,000 to 120,000 times

In general, an adult heart beats about 70 to 75 times per minute. That comes to roughly 4,200 beats per hour, and 4,200 × 24 hours = about 100,800 beats per day. Therefore, it is considered to beat approximately 100,000 to 120,000 times per day.

blood

Tears are produced in a place called the lacrimal glands, using blood as their source. Blood is red, but tears aren’t, because hemoglobin—the substance that gives blood its red color—is removed, making them transparent. I used to think tears had a similar composition to sweat, but they’re actually completely different.

Hold with your right hand

If your left foot hurts, carrying your luggage with your right hand can help you maintain balance. It reduces the load on the left foot and stabilizes your posture while walking, which can alleviate pain and help prevent secondary injuries. Conversely, carrying it with your left hand may increase the burden on your left foot and make you more likely to lose balance. If you carry items with both hands, depending on the weight, it can also be difficult to maintain balance. Therefore, when your left foot hurts, it’s best to carry your luggage with your right hand.

full in both hands

Vegetables are good for your health, so you’ll want to eat as many as possible—but it’s hard to know how much is ideal, right? As a guideline, aim for about two handfuls, roughly 350 grams. If two handfuls feels like a lot, especially if you have a smaller appetite, try cooking the vegetables to reduce their volume and make them easier to eat!

sit up

Eating breakfast kick-starts your body’s energy supply and boosts your metabolism. It provides the energy needed to recover from the overnight fast, raises your body temperature to wake up your body and brain, and helps improve focus and performance.

heart

The calves are called the “second heart” because the contraction of their muscles acts like a pump that pushes venous blood upward. This function promotes circulation throughout the body and helps prevent venous thrombosis. Make a habit of regular massage and similar care!
