Sleep Optimisation Protocol: Science-Backed Strategies for Restful Nights
Why Prioritizing Sleep Matters
Sleep is essential for cognitive function, emotional regulation, physical recovery, and long-term health. Chronic sleep deprivation is linked to anxiety, depression, weakened immune function, and metabolic issues. Implementing evidence-based strategies can help improve sleep quality and overall well-being.
Morning: Set Your Circadian Rhythm for the Day
Get Sunlight Exposure Within 30-60 Minutes of Waking
Aim for 10 minutes of natural sunlight if it’s bright out, and 30 minutes if it’s overcast.
If you wake up before sunrise, use bright indoor lights and get outdoor sunlight as soon as possible.
Avoid Caffeine for the First 90 Minutes After Waking
This prevents a cortisol crash and supports sustained energy throughout the day.
If consuming caffeine, limit intake after 2 PM to avoid disrupting sleep.
Engage in Light Physical Movement
A 5-10 minute walk or gentle stretching helps stimulate the nervous system and regulate your body clock.
Afternoon: Optimize Energy & Minimize Sleep Disruptors
Take a Non-Sleep Deep Rest (NSDR) or Yoga Nidra Break
A 10-20 minute NSDR session in the early afternoon enhances focus and promotes relaxation.
Guided NSDR scripts or Yoga Nidra apps can help with this.
Manage Caffeine & Food Timing
Stop caffeine at least 8-10 hours before bedtime.
Avoid large meals 2-3 hours before sleep to prevent digestive disruptions.
Exercise Early for Better Sleep Quality
Engage in moderate-to-intense workouts at least 4 hours before bedtime to avoid sleep disturbances.
Evening workouts? Opt for light resistance training or walking rather than high-intensity exercise.
Evening: Prepare the Body & Mind for Sleep
Limit Artificial Light Exposure After Sunset
Reduce overhead bright lights and use warm, dim lighting.
Avoid screen exposure (blue light from phones, laptops, TVs) 1-2 hours before bed. Use blue-light filters or night-mode settings if necessary.
Use Heat & Cold Strategically
A warm shower or bath 90 minutes before bed can help lower core body temperature and signal sleep onset.
Keeping your room cool (around 18-20°C or 65-68°F) supports deep sleep.
Avoid Alcohol & Late-Night Eating
Alcohol reduces deep sleep quality and disrupts REM sleep.
Eating late can increase body temperature and impact sleep latency.
Night: Fall Asleep & Stay Asleep
Create a Sleep-Inducing Environment
Total darkness: Use blackout curtains or a sleep mask.
Quiet space: White noise machines or earplugs can help if noise is an issue.
Comfortable bedding: Invest in a high-quality mattress and pillows.
Use a Wind-Down Routine
30-60 minutes before bed, engage in low-stimulation activities:
Reading (physical books, not screens)
Light stretching or breathing exercises
Journaling or reflection
Guided meditation (NSDR or Yoga Nidra)
Try Magnesium, Theanine, or Glycine for Sleep Support
Magnesium L-Threonate or Glycinate (300-400 mg) can promote relaxation.
L-Theanine (100-200 mg) helps reduce stress without sedative effects.
Glycine (2-5 g) may aid deep sleep and body temperature regulation.
(Always consult with a healthcare provider before taking supplements.)
Bonus: Dealing With Sleep Issues?
Waking Up in the Middle of the Night?
Avoid checking your phone or exposing yourself to bright light.
Use deep breathing techniques, progressive muscle relaxation, or NSDR to return to sleep.
Struggling With Falling Asleep?
Try slow-paced breathing (e.g., 4-7-8 breathing: Inhale for 4s, hold for 7s, exhale for 8s).
Engage in cognitive behavioral therapy for insomnia (CBT-I) techniques, like reducing sleep anxiety.
Sleep Debt Recovery
Don’t oversleep; instead, take a 20-30 minute NSDR nap during the day.
Maintain consistent wake-up times even after poor sleep.
