The final 20 minutes of the power-down hour should be devoted to relaxation practices such as meditation, prayer, warm compresses, breathing exercises, warm feet, audiobooks, aromatherapy, or light journaling.

The 4-7-8 breathing technique (proposed by Dr. Bruce) can lower heart rate and support relaxation during the power-down hour.

Stopping exercise 4 hours before bed prevents core body temperature elevation, which would delay the cooling process needed for sleep onset.

Stopping fluid intake 3 hours before bed prevents nighttime bladder filling and sleep disruption from bathroom visits.

Aromatherapy using lavender scents can promote relaxation before sleep, and should be delivered via diffuser rather than candles for safety.

Light journaling of thoughts and daily activities during the power-down hour can support relaxation and sleep onset.

During the first 20 minutes of the power-down hour, complete outstanding tasks like phone calls, emails, or texts to clear the mind before attempting sleep.

Caffeine blocks adenosine receptors and prevents the sleepy feeling from fully setting in, even when a person does not consciously feel more alert.

Alcohol destroys stage 3 (slow-wave or deep) sleep, which is the physically restorative sleep stage that becomes increasingly important with age.

The second 20-minute phase of the power-down hour should be dedicated to hygiene (brushing teeth, showering) and preemptive bathroom use to clear excess fluids from the system.

Warm compresses applied over the eyes for 5-10 minutes while lying in bed can promote relaxation and facilitate sleep onset.

Patience with the sleep improvement process and commitment to building the recommended strategies into sustainable habits are prerequisites for experiencing meaningful results.

Small light dinners focused on salads with protein or soups are recommended to facilitate faster gastric emptying before the pre-bedtime fasting window.

Listening to audiobooks or podcasts with non-stimulating content can support relaxation and sleep onset during the power-down hour.

Waking up in the middle of the night and feeling tired in the mornings is frustrating and a common complaint in sleep medicine practice.

Alcohol should be stopped 3 hours before bed and limited to a maximum of 2 drinks per day (with zero alcohol being optimal).

Drinking water between alcoholic drinks helps mitigate alcohol's sleep-disrupting effects.

Melatonin should be dosed between 0.5 and 1 milligram and taken approximately 90 minutes before lights out.

Melatonin lowers nighttime cortisol and stress levels, preventing stress-induced sudden awakenings.

Melatonin has anti-inflammatory and antioxidant benefits that reduce discomfort-related awakenings by mitigating tissue inflammation.
