Top Tips for Better Sleep and Circadian Health

We interviewed Daniel White – a self-described “reformed sleep saboteur” – of Sleep Better, Live Better about his top tips for better sleep and circadian health. You can watch the replay below. Please note that you will be asked to provide your email address at the 30-minute mark to continue viewing the replay.

What Is Circadian Rhythm and How Does It Affect Sleep?

The term circadian rhythm generally refers to the sleep-wake cycle that occurs within a 24-hour period. It is affected by exposure to sunlight as well as artificial light. A preponderance of research within the past decade (see Sources & References, below) shows that, in particular, the blue spectrum of artificial light given off by devices such as LED lights, computers, smartphones, tablets, TVs and electronic billboards can inhibit the production of melatonin, the hormone that helps us fall asleep. Because of the proliferation of these devices, more people than ever before – even children and teenagers – are having problems sleeping and feeling rested.

In This Webinar

Daniel White is an internationally renowned sleep expert who experienced his own sleep and health problems. After spending many years researching his health conditions, he concluded that sleep is enormously important to health and made it his life’s mission to help other’s experience better health and potential through better sleep. In this webinar, he’ll help us answer the following questions:

• What is circadian rhythm?
• How does circadian rhythm affect the ability to sleep?
• What happens when circadian rhythm is out of sync with the sun’s cycle?
• Which health conditions are associated with an out-of-sync circadian rhythm?
• What negatively affects circadian rhythm?
• How can circadian rhythm be resynced?

Daniel’s Key Steps for Optimal Light Exposure

• Get unfiltered sunlight exposure as close to sunrise as possible
• Get periodic exposure to unfiltered natural light throughout the day
• Get unfiltered exposure to natural light before/during sunset
• Mimic darkness at night
• Filter artificaial blue/green light after sunset

Daniel’s Key Steps for Addressing Nutrition

• Allow enough time for digestion before bed
• Consider practicing time-restricted eating so that all food is consumed within an 8-12 hour window
• Keep blood sugar levels optimized
• Supplement with magnesium glycinate (100mg per 10kg bodyweight)

Key Discussions

The Influence of Light on Circadian Rhythms

Natural-light exposure, especially in the morning, is essential for setting our circadian rhythms, while artificial light at night can disrupt melatonin production and negatively impact sleep. Managing light exposure can improve overall sleep quality and circadian health.

Chrono-Nutrition and the Timing of Eating

The timing of food intake (chrono-nutrition) significantly impacts metabolic health and circadian rhythms. Consuming food within a restricted eating window of 8-12 hours, avoiding late-night meals, and optimizing blood-sugar levels are crucial for better sleep and overall well-being.

The Role of Melatonin and Cortisol

Melatonin and cortisol are pivotal circadian hormones that follow natural release patterns influenced by light exposure and stress. Proper balance and timing of these hormones are crucial for optimal sleep quality and health, with light being a major regulator (“zeitgeber”).

The Impact of Modern Lifestyle on Sleep

Modern lifestyle factors such as indoor living, technology use, and artificial lighting have disrupted traditional sleep patterns and circadian rhythms, leading to various health issues. Making small lifestyle adjustments, such as managing light and screen exposure, can significantly improve sleep efficiency and health.

Educational and Practical Strategies for Better Sleep

Educating individuals about sleep hygiene, effective interventions such as blue-light blocking glasses, and practical measures like using circadian-friendly lighting are critical for improving sleep quality. There is an urgent need for disseminating research findings and implementing sleep education programs, especially for adolescents and caregivers.
