Second in the increasing mitochondria energy series is improving your circadian rhythm, also known as your sleep-wake cycle, which can have significant benefits for your overall health and well-being.
The Body Clock
The body clock, also known as the circadian clock or circadian rhythm, is a complex system that regulates various physiological processes and behaviors in organisms, including humans. The body clock works through a combination of internal biological mechanisms and external environmental cues to maintain a roughly 24-hour cycle. Here’s how it works:
- Internal Clock Mechanism: At the core of the body clock is a network of biological clocks located in the suprachiasmatic nucleus (SCN) of the hypothalamus in the brain. The SCN serves as the master clock that coordinates and synchronizes circadian rhythms throughout the body.
- Genetic Regulation: The body clock is regulated by a set of genes known as clock genes, which produce proteins that oscillate in a rhythmic pattern over a 24-hour cycle. These clock genes form interlocking feedback loops that drive the cyclical expression of other genes involved in circadian rhythms.
- External Environmental Cues: While the body clock has an inherent rhythm, it is also influenced by external environmental cues, known as zeitgebers, which help synchronize the internal clock with the external world. The most important zeitgeber for the body clock is light-dark cycles, particularly exposure to natural sunlight.
- Light-Dark Cycle: Light is the primary external cue that entrains the body clock to a 24-hour cycle. Photoreceptors in the retina of the eye detect changes in light intensity and transmit signals to the SCN, which adjusts the body’s internal clock accordingly. Exposure to light, particularly natural sunlight, during the day suppresses the production of melatonin, a hormone that promotes sleep, and signals the body to be awake and alert.
- Temperature and Other Cues: In addition to light, other environmental cues such as temperature, mealtimes, social interactions, and physical activity can also influence circadian rhythms to a lesser extent.
- Output Signals: The body clock regulates various physiological processes and behaviors, including sleep-wake cycles, hormone secretion, metabolism, body temperature, and cognitive function. Output signals from the SCN synchronize peripheral clocks located in cells and tissues throughout the body, ensuring that different physiological processes are coordinated and aligned with the internal clock.
- Adaptation and Flexibility: While the body clock maintains a roughly 24-hour cycle, it also has some degree of flexibility and adaptability. It can adjust to changes in environmental conditions, such as shifts in light-dark cycles (e.g., jet lag) or changes in work schedules, through a process called entrainment.
Here are some strategies to help optimize your circadian rhythm:
- Maintain a Consistent Sleep Schedule: Go to bed and wake up at the same time every day, even on weekends. Consistency helps regulate your body’s internal clock and reinforces your circadian rhythm.
- Expose Yourself to Natural Light: Get exposure to natural sunlight during the day, especially in the morning at dawn. Sunlight helps regulate your body’s internal clock and promotes alertness during the day. Spend time outdoors or near windows, particularly in the morning hours.
3. Limit Exposure to Artificial Light at Night: Minimize exposure to artificial light, especially blue light emitted by screens (e.g., smartphones, computers, TVs) in the evening. Blue light can disrupt your circadian rhythm and suppress the production of melatonin, a hormone that regulates sleep-wake cycles. Consider using blue light-blocking glasses or installing apps that reduce blue light emission on your devices.

4.Create a Relaxing Bedtime Routine: Establish a relaxing bedtime routine to signal to your body that it’s time to wind down and prepare for sleep. This may include activities such as reading, listening to calming music, taking a warm bath, or practicing relaxation techniques like deep breathing or meditation.
5.Limit Caffeine and Stimulants: Avoid consuming caffeine and other stimulants in the afternoon and evening, as they can interfere with your ability to fall asleep and disrupt your circadian rhythm. Opt for decaffeinated beverages or herbal teas instead.
6.Exercise Regularly: Engage in regular physical activity, but avoid vigorous exercise close to bedtime, as it can increase alertness and make it harder to fall asleep. Aim to complete your workout at least a few hours before bedtime to allow your body to wind down.
7. Create a Sleep-Conducive Environment: Make your bedroom conducive to sleep by keeping it cool, dark, and quiet. Use blackout curtains or eye masks to block out light, and consider using white noise machines or earplugs to minimize noise disturbances

8.Limit Naps: While short naps can be beneficial for some people, especially if they’re struggling with daytime sleepiness, long or frequent naps can disrupt your nighttime sleep and affect your circadian rhythm. If you do nap, try to keep it short (20-30 minutes) and avoid napping late in the day.
9. Eat a Balanced Diet: Maintain a healthy and balanced diet, and avoid heavy meals, caffeine, and alcohol close to bedtime, as they can disrupt sleep. Opt for lighter meals in the evening and avoid eating large meals right before bed.
10. Try using Essential oils: Equal parts Geranium EO, Pink Grapefruit EO, Tea Tree EO, Lavender EO, and Myrrh EO * (2 drops each) in a 10 ml roller bottle filled with NSP’sCarrier oil, fractionated coconut oil or grapeseed oil . Apply on both sides of your head above the ears; on the top of your head; in the middle of the back of your head. The pineal gland is located in the exact center of the brain, level with your eyes, which helps the gland register and respond to light to release melatonin. It’s ideal to use this blend before bedtime in a low-light atmosphere to allow the pineal gland to respond appropriately.
11. Use Essential oils to support the Hypothalamus: 3 drops Lavender EO, in 10 ml roller bottle filled with NSP’sCarrier oil, * fractionated coconut oil or grapeseed oil. Apply on the forehead (Third Eye) before bed and several times a day to help with stress.
Overall, the body clock is a sophisticated biological system that regulates the timing of various physiological processes and behaviors to optimize organismal function and adapt to the changing environment. Disruptions to the circadian rhythm, such as irregular sleep patterns or exposure to artificial light at night, can have adverse effects on health and well-being, highlighting the importance of maintaining a healthy circadian rhythm.
By incorporating these strategies into your daily routine, you can help optimize your circadian rhythm, improve the quality of your sleep, and promote overall health and well-being.
