Establishing a Healthy Sleep Routine

The Concept of Sohan (Season of The Lesser Cold)

Sohan is the 23rd of the 24 solar terms, falling between Dongji (Winter Solstice) and Daehan (The Greater Cold), when the sun reaches a celestial longitude of 285 degrees. It is traditionally considered the coldest time of the year, with the 15-day period from Sohan to Daehan marking the absolute peak of winter chills.

Wisdom from the Dongui Bogam

According to the Dongui Bogam (Principles and Practice of Eastern Medicine), the three months of winter are referred to as Pajang (폐장)—a period of closing and storing. During this time, water freezes, the earth cracks, and the Yang energy remains still and unmoving.

The text advises the following lifestyle practices for winter:

• Sleep Schedule: Go to bed early and wake up late, ensuring you only get out of bed after the sun has risen.

• Mental State: Keep your mind calm and internalize your intentions rather than expressing them frantically to the outside world.

• Body Temperature: Ward off the cold and seek out warmth. Avoid excessive sweating caused by overheating, as it can deplete your body's energy (Qi).

"This is the proper way to nourish your body and attune yourself to the winter season."

Modern Scientific Insights on Winter Sleep

Recent studies support this ancient wisdom, revealing that humans naturally need more sleep during the dark, cold winter months than in the summer. This is due to seasonal shifts in human sleep patterns. If you find yourself sleeping more these days, you can rest assured that your body is perfectly synced with winter.

According to a study conducted in Germany, people experience longer periods of REM sleep and deep sleep during winter compared to summer:

• REM Sleep: The most active stage of sleep, where dreaming occurs and the heart rate increases.

• Deep Sleep: A vital stage where the body repairs muscles and tissues, and consolidates long-term memory.

Establishing a Healthy Sleep Routine

Now, let's explore the lifestyle routines that can help banish insomnia and improve sleep quality during these long winter nights.

1. Planting the "Serotonin Seeds" in the Morning

(The Daytime Secret)

If you want melatonin (the sleep hormone) to flood your system at night, you need to set the stage by producing serotonin (the happiness hormone) exactly 15 hours before bedtime. But here’s the catch: serotonin doesn't just magically appear the moment you open your eyes. Your body needs two strict conditions met to wake this hormone up:

• Condition #1: You ABSOLUTELY need morning sunlight!

  Staying indoors all morning and only stepping out later in the afternoon won't cut it. Why? Because regular indoor lighting is only about 300 to 500 lux—way too dim. To actually stimulate your brainstem and get that serotonin flowing, you need a light intensity of at least 3,000 lux. Luckily, even on a cloudy, rainy, or snowy day, outdoor light hits over 10,000 lux. So, no excuses about the weather! Make it a rule to step outside every single morning and let that natural light hit your eyes.

• Condition #2: Get into a "Rhythmic Movement."

  Don't overthink the word "rhythm"—just think of your heartbeat. That steady thumping is proof that you're alive. Being alive is a beautiful thing, and our bodies are beautifully hardwired to release happiness hormones when we lean into that rhythm. What counts as rhythmic movement? Simple walking! Go for a light stroll, put on some upbeat music, and move your body to the beat to wake your system up.

The Serotonin Formula: Every morning, step outside, get under the sunlight, and move rhythmically (like a brisk walk) for about 30 minutes!

2. Flipping the Switch from Serotonin to Melatonin

(The Nighttime Rule)

Once you’ve built up that serotonin during the day, your body gets ready to convert it into melatonin about 15 hours later. But again, this switch doesn't just flip automatically over time. There is one golden rule you must follow:

• The Golden Rule: Keep light OUT of your eyes!

  We’ve all been there: "Ugh, I can't sleep. Let me just check my phone." The moment you do that, game over! Countless studies prove that the blue light from smartphones intensely jolts your brain awake. The exact millisecond light enters your eyes, your brain hits the STOP button on melatonin production.

• The Fix: Total Blackout!

  You need to block out all light at night. If you can't get your room pitch black, I highly recommend grabbing a soft, lightweight sleep mask. It works wonders.

The Big Picture

If you want to treat yourself to a night of amazing sleep, it all starts in the morning. Step outside when the sun comes up, take a walk, and plant those "serotonin seeds." As long as you plant them early, all you have to do at night is block out the light.

Do that, and your daytime serotonin will seamlessly convert into melatonin—your body's ultimate natural antioxidant—guaranteeing you drift off into a deep, sweet sleep!
