Ambient Light Dimming
Turn off the overhead light, keeping only warm-toned ambient light (table lamp or floor lamp). Wear blue-light-blocking glasses to send a 'night is coming' signal to the suprachiasmatic nucleus.
Sleep Optimization Protocol
Deep Sleep & Neural Repair--
Waking up early and light, dream-filled sleep in middle age are signals of hormonal and neural tension changes. Through fine-tuning ambient light and heat and circadian rhythm reset, recover lost slow-wave sleep without relying on medication.

Core Body Temperature Trick
Take a warm bath (not extremely hot). When you step out into the cooler air, your core body temperature drops rapidly, which is the key trigger for the biological clock to induce strong sleepiness.

Screen Block & Supplements
Leave your phone outside the bedroom. Take the evening neural calming supplement matrix (magnesium, L-theanine, etc.) and read a physical book under soft light to bring cortical activity to zero.
