Simple Pleasures of Life #11

Sleep.

Sleep seems to be the most contradicting thing in my life. So often I wish I didn’t have to sleep so I could do more in my day, yet I fucking LOVE sleep. I’d sleep centuries if I could. There’s something nice about the thought that every day, you just switch off for a little while (except for dreams which are awesome in their own right). Plus, I find the subject of sleep absolutely fascinating, as you probably gathered from my pile of ARK posts

Caffeine

Coffee is a magical drink that can make a busy person’s morning. Coffee’s stimulant effect is due to the substance called caffeine. Caffeine can make the mind more alert and drives away sleepiness for about 3~4 hours. This is why students studying for an exam or people working late love to drink coffee.
There are many students who say they do not like coffee and drink energy drinks instead. These drinks tend to advertise that the substances guarana and taurine give energy, but an interesting fact is that guarana is just a plant where caffeine is extracted from. Taurine has many beneficial actions in the body, but has no effect as a stimulant. Therefore, an energy drink is simply made of caffeine and sugar and holds no advantage over coffee.

Although caffeine is beneficial in moderate amounts, excessive consumption leads to adverse effects. A normal adult can handle up to about 400mg of caffeine. Any more and they could suffer from anxiety, insomnia, headaches, dehydration, increased urination, fever, rising heart rate, stomach pain, nausea and many other symptoms. As everyone’s rate of caffeine metabolism is different, only they know how much caffeine they can consume. Furthermore, the more coffee or tea you drink, you build a tolerance towards caffeine and can consume much more without adverse effects.

The following is a list of the caffeine content in common drinks and foods:

  • Drip coffee(200ml): 150mg
  • Espresso(50ml): 100mg (this is because the cups are small, the concentration is about 3 times that of drip coffee)
  • Caffeine tablet: 100mg
  • Energy drink(250ml): 80mg
  • Coca-cola(600ml): 60mg
  • Chocolate(250g): 60mg
  • Black tea(170ml): 50mg
  • Green tea(170ml): 30mg
  • Decaffeinated coffee(200ml): 10mg

However, the best method to drive away sleepiness is by sleeping. If you are tired, the only way to recover is by taking a 30 minute to 2 hour nap, especially if you will be driving or have a night shift.

Shrew

A shrew is a small rodent, similar in size to a rat, that has many fascinating characteristics.

Funnily enough, this animal has a notorious name in history. Ancient Egyptians considered shrews the spirits of darkness and the English believed that if a shrew ran over a lying animal, the animal would suffer great pain. The name shrew comes from the Middle Age English word shrewe, which meant “evil” or “scolding person”.
This is probably attributable to the putrid smell a shrew makes when threatened, and its poisonous bite.

Despite its tiny figure, the shrew has the greatest surface-area-to-weight ratio out of any mammal on the face of the Earth. Because of this, they also have a high heat expenditure, meaning they have to eat constantly to replenish the energy. This means that they sometimes die from starvation during prolonged naps.
Also, they have an extremely high heart rate, averaging about 700 beats per minute. When they are frightened, the heart rate can spike leading to cardiac arrest. For example, shrews are known to die from being frightened by the sound of thunder.

An animal that dies if it naps too much or when thunder strikes – the shrew is a very sad animal.

Dali Nap

The famous surrealist artist Salvador Dalí had a strange habit. When he could not solve a problem or had difficulty coming up with an idea, he chose to nap. However, he did not nap “normally” to say – he used a unique method.

First, find a comfortable sofa or armchair, a spoon and a large plate or pan. Sit in a comfortable way, flip the plate over and place it on the ground, then hold the spoon directly above it with only your thumb and index finger. While thinking about the problem you want to solve, fall asleep.

As soon as you enter REM sleep, all of your muscles will relax and so the spoon will fall onto the plate, making a loud clatter. As soon as you get woken up by this, you will not only feel well rested, but also discover the solution or idea you were looking for.
