Why did my glucose spike… I didn’t even eat? 🤔🔥
This came up on our call today and it’s an important “aha.” Because your CGM isn’t just tracking food…👉 it’s tracking your physiology 1. Stress = a glucose rise (even without food) When your body perceives stress—(emotional, mental, lack of sleep, rushing, overwhelm) It activates your fight-or-flight response This means: - Cortisol ↑ - Adrenaline ↑ Your body is essentially saying:👉 “We need quick energy to handle this.” So your liver: - releases stored glucose - may even make new glucose 📈 Result: your blood sugar rises… even if you haven’t eaten 2. Heat (sauna / hot shower) can do the same thing 🔥 Heat is actually a controlled stressor When you’re in a sauna or hot shower: - heart rate increases - your body works to cool itself - stress hormones rise temporarily 👉 Same signal: “We need energy” So again: - your liver releases glucose - you may see a temporary bump on your CGM 3. This is NOT a bad thing (context matters) Your body is designed to do this 👇 Short-term:✔️ Helps you respond✔️ Fuels your brain + muscles✔️ Supports adaptation But… If stress is happening all day, every day➡️ glucose can stay elevated more often than we want 4. The key takeaway 👉 Not every glucose rise is about food 👉 Not every spike is “bad” Your CGM is showing you: - stress - recovery - environment - physiology in real time This is a good reminder to shift our mindset to this: “This isn’t good or bad… it’s information.” Your experiment this week 👇 Pay attention to: - stress moments - rushing / multitasking - hot showers / sauna And ask: 👉 “What is my body responding to right now?”
