Instead of sleeping soundly and then waking up with a head as heavy as lead, he chose the strategy of dozing off after drinking coffee. As soon as his eyes began to clench, he drank a glass of iced black coffee very strongly and dozed off for exactly 10 minutes right at his desk. The secret lies in that: caffeine needs that much time to absorb into the blood. Right when the alarm rang, the coffee had just soaked into the cells, he woke up awake like a computer had just been restarted.
The biggest mistake of a night laborer that he once paid the price for was eating a bowl of tái gầu pho full at 11 pm. Only 15 minutes later, his brain officially "exited" because the blood had to be pumped all down to the stomach for digestion. Wanting to stay up late but his brain still had a chance, he had to eat upside down like a sparrow. A few almonds, an apple, or at most a cup of cereal powder. When the stomach is not too full, the body will maintain a state of survival, helping the mind to be extremely sharp and focused.
There were nights working until 3 am, instead of tiredly looking at the clock, he calmly calculated according to the circadian rhythm. Knowing that the human brain operates every 90 minutes, he set the alarm to exactly 6 am, just right for two cycles. Strangely, when the bell rang, he woke up like a spring. The secret is not to let the alarm interrupt when he is deep in sleep. It is better to sleep less but in the right rhythm than to sleep more but be awakened halfway.
The next morning, he decided to "treat" himself by putting his face in a basin of freezing ice water. The heat shock along with a little sunlight like a natural doping, his brain was immediately awakened to get into work immediately.
Of course, working productively when sleeping less also needs a big enough fear. When deadlines are hanging overhead, he has to practice turning each report into a game to conquer. He understands that the secret is not in panacea, but in discipline and behavior with his own body. However, he still secretly tells himself that on weekends he must allow himself to "land" with a deep sleep, before his body objects and automatically presses the shutdown button right on his desk.
