Flinching in his sleep.

I'm going to watch Indra... 😴

Suddenly dreaming of walking down a pipe or falling off a building!

And then the legs twitched. "Bang!" Kick up, heart pounding!

Who was it? Is it a ghost pushing or a spirit leaving the body? 👻

Calm down, sir...This condition, called "Hypnic Jerk," is common to everyone (especially people who are stressed or sleep-deprived).

The most popular reason scientists assume is: "The brain misunderstands you as dying!" 💀

📉 vital signs go down when we're going to sleep...The body goes into energy-saving mode, the muscles loosen, the heart rate slows down, and the body temperature drops rapidly.

🧠, the brain is awake, the brain controls instinct, misinterprets this "flare"! It says, "Hey! Low pulse! Muscle weakness! Are we dying or falling from a tree?" (Ancestral monkey instinct) 🐒

⚡ emergency heart pump, so the brain immediately sends a "high voltage" to stimulate the muscles to keep us awake! As a result, we twitch like a shock to make sure we're alive and clinging to a tight branch!

The conclusion is that the brain is hopeful (but a little shocked), so wake us up to check the name. 😂

The human body has an amazing complex defense system to unravel brain secrets at the post-degree Siriraj.

Who often "falls into the abyss" on nights, notice if they're stressful or have too much coffee? 👇

... Read moreหลายคนอาจเคยประสบกับอาการตกใจสะดุ้งขึ้นมาระหว่างที่กำลังหลับหรือตกลงจากที่สูงในความฝัน สาเหตุที่แท้จริงของอาการนี้เรียกว่า Hypnic Jerk หรือ Myoclonus เป็นปรากฏการณ์ที่เกิดขึ้นในช่วงเปลี่ยนผ่านระหว่างตื่นกับหลับลึก ซึ่งสมองจะตีความผิดว่าสัญญาณชีพของร่างกายลดต่ำลงและเข้าใจว่าร่างกายกำลังตกอยู่ในอันตราย เช่นเดียวกับบรรพบุรุษที่อาศัยอยู่บนต้นไม้ จึงเกิดการกระตุกแบบฉับพลันเพื่อป้องกันตนเองไม่ให้ตกลงมา จากประสบการณ์ส่วนตัว พบว่าอาการสะดุ้งนี้จะเกิดขึ้นบ่อยขึ้นเมื่อมีความเครียดสะสมหรือการนอนที่ผิดเวลาทำให้ร่างกายพักผ่อนไม่เพียงพอ รวมทั้งคาเฟอีนจากกาแฟและเครื่องดื่มที่มีสารกระตุ้นอื่น ๆ ก็เป็นปัจจัยที่ทำให้อาการหนักขึ้น นอกจากนี้การออกกำลังกายหนักก่อนนอนยังอาจทำให้ระบบประสาทตื่นตัวเกินไปและส่งผลให้อาการเกิดง่ายขึ้น เพื่อบรรเทาอาการนี้ แนะนำให้ปรับพฤติกรรมการนอนให้เป็นเวลา ลดการบริโภคคาเฟอีนในช่วงบ่ายถึงเย็น และปฏิบัติการผ่อนคลายก่อนนอนเช่น การทำสมาธิหรือฟังเพลงที่สงบ เพียงเท่านี้ก็ช่วยลดโอกาสการสะดุ้งกลางดึกได้อย่างมีประสิทธิภาพ การเข้าใจธรรมชาติของ Hypnic Jerk ช่วยให้เราไม่ต้องวิตกกังวลมากนักเพราะเป็นปฏิกิริยาปกติของร่างกายที่มีวิวัฒนาการมานานเพื่อช่วยปกป้องตัวเอง แต่หากอาการเกิดบ่อยจนส่งผลกระทบต่อการนอนและความเหนื่อยล้าในชีวิตประจำวัน ควรปรึกษาแพทย์หรือนักนอนหลับเพื่อรับคำแนะนำที่เหมาะสมและตรวจหาสาเหตุที่ลึกลงไปเพิ่มเติม

Why you pull away from his touch 🫶✨
Your body remembers what your heart tried to forgive. He hurt you. Now your nervous system treats his hands like a threat. That flinch isn’t “drama.” It’s your body saying never again. You don’t owe him access to you just because he said sorry. Healing means honoring that flinch
