Your first scenario

The fastest way to learn the lab is to model a typical day for yourself and see how the chart responds.

Step-by-step

• Add a sleep block (e.g., 11pm–7am)
• Add a morning coffee (e.g., 8am, 200 mg caffeine)
• Add breakfast (e.g., 8:30am, oatmeal + eggs)
• Add a workout (e.g., 5pm, 45-min cardio)
• Watch the chart update as you add each item
• Drag the playhead through the day to see signal values
• Toggle different signals (cortisol, glucose, dopamine) to find what changes

What to notice

• Caffeine pushing cortisol up + adenosine down
• Breakfast spiking glucose then insulin
• Exercise raising heart rate proxy + dopamine
• Melatonin rising before bed
