Section 1.1: Consistent Wake-Up Time

To enhance our circadian rhythms, consistency is key. Our overall health flourishes when these natural clocks are well-regulated. The first step in this process is to wake up at the same time daily, regardless of whether it's a weekday or weekend.

Our hormones and metabolic functions rely on a predictable schedule, but modern lifestyles often disrupt this balance. In our ancestral past, we typically woke with the sunrise and maintained a regular schedule for eating and activities, going to bed shortly after dusk. The chaos of late-night work parties or irregular shifts can throw our bodies out of sync, adversely affecting our health.

Section 1.2: Importance of Daylight Exposure

I’ve always appreciated the outdoors, but only recently have I recognized its vital role in our health. Morning sunlight serves as one of the most powerful signals for regulating our circadian rhythms. Ideally, aim to bask in bright light (preferably sunlight) within the first 20 minutes of waking up to help optimize these rhythms.

Continuous exposure to natural light throughout the day is also essential, while minimizing artificial light exposure. Aim for at least an hour of bright daylight daily, targeting around 1000 lux of light. A helpful tool is the free MyLux app, which can measure light levels. Whenever possible, spend time outside, and if you’re indoors, keep curtains open and sit near windows.

Section 1.3: The Importance of Regular Movement

In our sedentary society, frequent movement is crucial yet often neglected. Many of us find ourselves sitting for extended periods—whether commuting, working at a desk, or relaxing at home. The saying "sitting is the new smoking" holds true, as prolonged sitting is associated with various health issues, including heart disease, diabetes, and even early mortality, alongside mental health concerns.

To promote health, we must prioritize regular movement—not necessarily through structured exercise, but simply by moving more. I personally aim for at least 6,000 steps a day and strive to move for at least five minutes every hour. While this may sound straightforward, it can be quite challenging.

Utilize reminders if necessary. Keep a kettlebell nearby for quick workouts, or have a yoga mat out for stretches. Here are some practical strategies to incorporate more movement into your day:

• Walking: Opt for walking instead of driving when possible. Park farther from store entrances and explore all aisles while shopping.
• Stair Climbing: Choose stairs over elevators or escalators.
• Chores: Engage in household tasks like vacuuming or sweeping—they need to be done anyway!
• Standing: Consider using a standing desk, or simply stand while waiting or during TV commercial breaks.
