Overview

Insomnia: Check these three things first

  • Insomnia refers to a recurring state where you have the opportunity to sleep but find it difficult to fall asleep, wake up frequently, or wake up too early, making it difficult to function the following day.
  • distinguish it from a lack of sleep due to insufficient time to sleep sleep deprivationand identify factors that interfere with sleep, such as sleep apnea, restless legs, mood changes, or medications.
  • Do not just estimate the time you fell asleep; record the wake-up time, nighttime awakenings, naps, caffeine intake, and next-day functioning sleep diaryin your records.

Meaning and Distinctions

What is insomnia?

Insomnia is a state where you have the opportunity to sleep but find it difficult to fall asleep, wake up frequently, or wake up too early, causing your concentration, mood, and work performance to suffer the next day. Rather than looking only at the time it takes to fall asleep, record nighttime awakenings, final wake-up time, daytime sleepiness, and fatigue. Reduce the time spent staring at the clock and focus on restoring a consistent wake-up time and daytime concentration. If you experience loud snoring, sleep apnea, drowsy driving, an elevated mood where you do not feel tired despite lack of sleep, or thoughts of self-harm, please seek the appropriate medical evaluation first.

Easily confused terms
Unlike sleep deprivation, which is a lack of time to sleep, insomnia is characterized by the difficulty of sleeping even when the time and environment for sleep are available.
Why this is checked during medical evaluation
First, distinguish the effects of sleep apnea, restless legs, mood disorders, and medications. When insomnia persists after that evaluation, Korean herbal medicine treatment focuses on relieving tension, digestive issues, and body heat that persist through the night and improving next-day recovery, rather than simply forcing sleep. Pattern Identificationdoes.
What to write down for your visit
Use a sleep diary to see how habits such as lying down too early, oversleeping, napping, checking the clock, and using sleeping pills correlate with nighttime anxiety. Provide your current diagnosis, test results, psychotherapy stage, and a complete list of medications including prescriptions, over-the-counter drugs, and supplements. We prescribe treatment by examining which symptoms actually change along with your sleep, such as throbbing after worrying, nighttime heat sensations, chest tightness, or decreased appetite and energy. Please write this information down with the dates and show it during your consultation.

Connecting insomnia to your symptoms

Record nighttime hours and next-day functioning together

Record the time you lay in bed, the time you believe you fell asleep, the number of times you woke up, and the final wake-up time, as well as your next-day sleepiness, concentration, and mood. Note whether habits like lying down too early, oversleeping, napping, and checking the clock are recurring. These records are used to find which habits increase nighttime anxiety rather than to calculate perfect sleep hours.

Distinguish other conditions that may look like insomnia

Loud snoring and sleep apnea, leg discomfort, nighttime pain, or awakenings after changing medication may require separate evaluation. In particular, if you do not feel tired despite almost no sleep and your speech, activity, and spending increase significantly more than usual, do not simply adjust sleeping pills for simple insomnia Hypomaniabut promptly check for the possibility of hypomania or mania.

Frequently Asked Questions

Frequently asked questions about insomnia

How few hours of sleep constitute insomnia?

It is not determined by sleep duration alone. We consider whether there was an opportunity to sleep, whether difficulties in falling asleep, maintaining sleep, or early awakening are recurring, and the impact on the following day's life.

Can I take more sleeping pills if I cannot sleep?

Do not arbitrarily increase the dose or mix them with other sedatives. You must record the time of intake, the effects, and any next-day sleepiness or memory issues to safely adjust the dosage with your prescribing healthcare provider.

Key Points

  • Definition of insomnia: Insomnia is a state where, despite having the opportunity to sleep, you have difficulty falling asleep, wake up frequently, or wake up too early, leading to impaired concentration, mood, and work performance the following day.

  • Difference from similar terms: Unlike sleep deprivation, where there is a lack of time to sleep, insomnia is identified by the fact that sleep is difficult even when the time and environment for sleep are available.
  • Reason for checking during medical evaluation: We first distinguish the effects of sleep apnea, restless legs syndrome, mood disorders, and medications. When insomnia persists after that evaluation, Korean herbal medicine treatment focuses on pattern identification (Byeonjeung) of tension, digestion, and body heat that remain unresolved at night, as well as recovery for the following day, rather than simply aiming to force sleep.
