Traits of People Who Fall Asleep Fast

People who fall asleep quickly seem to possess a special ability. However, in most cases, it is not a special ability but a difference in biological clocks and lifestyle habits.

Many people search for ways to sleep quickly. But sleep is not an action created by willpower. Rather, it is close to a phenomenon that arrives naturally when the body completes its preparation to sleep.

Traits of People Who Fall Asleep Fast

1. The Biological Clock is Consistent

Our bodies possess an internal biological clock. A person who falls asleep and wakes up at similar times every day maintains a stable biological clock.

Conversely, if wake-up times between weekdays and weekends differ significantly, night owl tendencies are frequent, or bedtime changes often, the biological clock can experience confusion. Sleep research indicates that regular bedtime and wake-up times can assist in stable sleep. The more consistent the biological clock is maintained, the easier it becomes for the body to predict when to fall asleep and when to wake up.

2. Sufficient Sleep Pressure has Accumulated

Sleep does not come simply because it is night. The longer you stay awake during the day, the more pressure to sleep accumulates. This is called sleep pressure.

Taking long afternoon naps or lying down all day can prevent sufficient sleep pressure from building up. As a result, you may find it difficult to fall asleep at night.

In sleep science, it is known that the longer you remain awake, the more a substance called Adenosine accumulates, inducing sleepiness. When sufficient adenosine accumulates, the body naturally wants sleep. Conversely, late naps or excessive rest can disrupt this process.

3. They Do Not Try to Fall Asleep

Interestingly, the harder you try to sleep, the more sleep eludes you.

"I need to sleep quickly"
"I have to wake up early tomorrow"
"What if I can't sleep again?"

Such thoughts can actually place the brain in a state of alertness. Sleep is not obtained through effort, but is close to a state the body naturally accepts.

Scientific Evidence

Sleep research explains that excessive worry and pressure about sleep can increase alertness. This is referred to as Psychological Arousal. The body is tired, but the head remains awake. Now, try saying this to yourself:

4. They Do Not Use Phones for Long Before Bed

Many people use mobile phones before sleeping. However, the strong light from phone screens can send a signal to the brain that it is still daytime. Consequently, the body delays its preparation for sleep.

Scientific Evidence

Indeed, the 2017 Nobel Prize in Physiology or Medicine was awarded for research on the genes that build the biological clock. Researchers discovered through experiments on fruit flies that an internal biological clock of approximately 24 hours exists in living organisms. The biological clock reacts very sensitively to light. In particular, strong light at night can push the biological clock back, delaying bedtime. Therefore, using smartphones before bed can have a larger impact on sleep than expected.
