Sleep Success: Build Better Sleep Habits in 40 Minutes

Discover how sleep resets the body and mind, recharging performance as brain activity, heart rate, and hormones shift. See how sleep consolidates memories and boosts well-being and cognition.

Learn your optimal sleep duration, using seven hours as a baseline and considering age and lifestyle. Discover science-based tools to improve sleep quality via light and temperature cues.

Align your light exposure to regulate your circadian rhythm and internal clock, stabilizing your sleep-wake cycle and improving sleep quality and daytime alertness by maintaining a consistent routine.

Expose yourself to the morning sun within 30-60 minutes of waking for 5-30 minutes outdoors to activate circadian rhythm and cortisol. Avoid glass and sunglasses, and aim for 80% days.

Expose your eyes to afternoon and evening sunlight to optimize sleep and protect your nervous system from artificial light, with 5–10 minutes on clear days and 20–30 minutes when cloudy.

Avoid bright artificial lights at night by dimming after sunset, using low lighting, moonlight or candlelight, and blue blockers to protect your internal clock.

Expose your mornings to cold temperatures to signal wakefulness and evenings to warm temperatures to wind down, synchronizing your circadian rhythm for better sleep and wake patterns.

Practice science-based cold water immersion for 1–3 minutes each morning with cold showers or ice bags to boost adrenaline, dopamine, alertness, and focus, supporting sleep and fat loss.

Learn to use hot baths or saunas for 10 to 20 minutes in the afternoon at 80 to 100 C to raise body temperature and trigger a sleep-ready cool-down.

Lower your bedroom temperature about three degrees Fahrenheit to help your body cool and fall asleep. Go barefoot and allow a foot outside the blanket to regulate heat.

Build a science-based personalized sleep plan to achieve seven hours, set bed and wake times, and follow morning sunlight, afternoon light management, and dim lights, plus cold exposure and sauna.

Congratulations on completing the course and implementing your plan to improve sleep and wake refreshed each morning. Apply these easy sleep protocols to transform your sleep and performance.
