Cycles and frequencies

Sometimes engaging with life's cycles seem like spinning plates on sticks.

One way to achieve more for less effort is to synchronise into a rhythm.

We have Circadian cycles.

The human circadian cycle, also known as the "body clock," is a natural, internal process that regulates various physiological and behavioural processes in the body over a 24-hour period. The circadian cycle is controlled by a complex network of interactions between the brain, hormones, and other internal and external factors.

The primary internal factor that affects the circadian cycle is the suprachiasmatic nucleus (SCN), a small region of the hypothalamus in the brain,  situated directly above the optic chiasma, that controls the timing of the body's internal clock. The SCN receives input from the eyes about the light-dark cycle in the environment and adjusts the circadian rhythm accordingly.

External factors that can affect the circadian cycle include exposure to light and darkness, temperature, noise, and social cues such as meal times. Artificial light exposure, especially at night, can disrupt the natural rhythm of the body clock. Shift work and jet lag can also disturb the circadian rhythm.

Disruptions to the circadian cycle can lead to various health problems such as insomnia, depression, cardiovascular disease, and cancer. To maintain a healthy circadian rhythm, it's recommended to have a consistent sleep schedule, exposure to natural light during the day, and limited exposure to artificial light at night. It's also important to avoid stimulating activities and screens, such as using electronic devices before bedtime, as this can disrupt the natural production of melatonin, a hormone that helps regulate sleep.  Are you reading this at bedtime?

We have Circasemidian cycles.

Circaseptan cycles, also known as circaseptan rhythms or ultradian rhythms, refer to the cyclical patterns of physiological and behavioural processes that occur over a period of roughly 7 days (or one week). These rhythms are thought to be driven by internal biological clocks that are independent of the 24-hour circadian rhythm.

Circaseptan rhythms have been observed in a variety of physiological processes, including heart rate, blood pressure, body temperature, and hormone levels. However, the scientific understanding of these rhythms is limited and the exact mechanisms that drive them are not fully understood.

Some of the factors that are thought to affect circaseptan rhythms include exposure to light and darkness, temperature, and social cues such as meal times. However, the impact of these factors on circaseptan rhythms is not well understood.

It is worth mentioning that Circasemidian cycles are not well-established in the scientific community and there is little evidence to support their existence. Research on this subject is scarce, and more studies are needed to understand if these rhythms truly exist and what the factors that regulate them are.

We have Ultradian cycles.

Ultradian rhythms refer to cyclical patterns of physiological and behavioural processes that occur over a period of less than 24 hours. These rhythms are thought to be driven by internal biological clocks and can occur in parallel with the circadian rhythm.

Ultradian rhythms have been observed in a variety of physiological processes, including heart rate, blood pressure, body temperature, hormone levels, and cognitive function. Some examples of ultradian rhythms include the 90-minute sleep cycle and the 90-minute basic rest-activity cycle (BRAC).

The exact mechanisms that drive ultradian rhythms are not fully understood, but they are thought to be influenced by a combination of genetic, environmental and lifestyle factors. The following are some examples:

• Sleep-wake cycle: The ultradian rhythm of sleep-wake cycle is regulated by the circadian rhythm and the homeostatic process of sleep pressure.

• Eating patterns: Hunger, satiety, and digestion are regulated by a combination of hormones, neural signals, and environmental cues.

• Hormone secretion: Hormones such as cortisol, insulin, and thyroid hormones have ultradian rhythms that are regulated by a combination of neural and endocrine signals.

• Mental and physical activities: Ultradian rhythms in mental and physical activities can be influenced by factors such as stress, physical exertion, and exposure to light and noise.

The body's internal clocks and the environmental cues interact to regulate the ultradian rhythms. The better you understand these rhythms and how they interact with your lifestyle, the better you can manage your health and optimize your performance.

We have a Circulatory system cycle

The circulatory system is a body-wide network of blood, blood vessels, and the heart, which is responsible for pumping blood throughout the body. The circulatory system has a cyclical pattern known as the cardiac cycle, which describes the sequence of events that occur during one heartbeat.

The cardiac cycle is made up of two main phases: systole and diastole. During systole, the heart contracts, and blood is pumped out of the heart and into the bloodstream. During diastole, the heart relaxes and fills with blood that is returning to the heart from the body. The cardiac cycle repeats continuously and regulates the flow of oxygen and nutrients to the body's tissues, and the removal of waste products.

There are several factors that can affect the circulatory system cycle:

• Heart rate: the number of times the heart beats per minute. Factors that can increase heart rate include physical activity, stress, and certain medications. Factors that can decrease heart rate include relaxation, sleep, and certain medications.

• Blood pressure: the force exerted by blood on the walls of the blood vessels. High blood pressure, or hypertension, can be caused by factors such as obesity, high salt intake, and stress. Low blood pressure, or hypotension, can be caused by factors such as dehydration and certain medications.

• Blood flow: the amount of blood that is pumped by the heart and delivered to the body's tissues. Factors that can affect blood flow include blood vessel health and the presence of plaques or clots in the bloodstream.

• Cardiac output: the amount of blood pumped by the heart per minute. Factors that can affect cardiac output include heart rate, blood pressure, and blood flow.

• Blood vessel health: factors such as age, hypertension, smoking, high cholesterol, and diabetes can affect the health of blood vessels, leading to conditions such as atherosclerosis, which can impede blood flow.

It's important to maintain a healthy lifestyle, including regular exercise, a balanced diet, and managing stress, to keep the circulatory system functioning properly. It's also important to have regular check-ups with a healthcare professional to monitor any potential risk factors or diseases associated with the circulatory system.

Women have Menstrual cycles.

The menstrual cycle is the regular process that occurs in the female reproductive system that prepares the body for pregnancy. The menstrual cycle is controlled by hormones, and it typically lasts 28 days, but it can vary from 21 to 35 days.

The menstrual cycle is divided into three phases:

1. The menstrual phase: This phase lasts for about 3-7 days and is characterized by the shedding of the lining of the uterus, also known as the endometrium. This results in the menstrual bleeding, also known as period.

2. The follicular phase: This phase lasts for about 14 days and is characterized by the development of a follicle in the ovary. The follicle contains an egg that will be released during ovulation.

3. The luteal phase: This phase lasts for about 14 days and begins after ovulation. The ovary produces progesterone, which helps to thicken the endometrium in preparation for a potential pregnancy.

The menstrual cycle is regulated by a complex interplay of hormones produced by the hypothalamus, pituitary gland, and ovaries. The following are some examples:

• Follicle-stimulating hormone (FSH) and luteinizing hormone (LH): These hormones are produced by the pituitary gland and regulate the development of the follicle and ovulation.

• Estrogen and progesterone: These hormones are produced by the ovaries and regulate the growth and shedding of the endometrium.

• Gonadotropin-releasing hormone (GnRH): This hormone is produced by the hypothalamus and regulates the production of FSH and LH.

Several factors can affect the menstrual cycle, such as stress, changes in weight, excessive physical activity, and certain medical conditions such as Polycystic Ovary Syndrome (PCOS), thyroid disorders, and pituitary gland disorders. Some medications and contraceptives can also affect the menstrual cycle. It's important to consult a healthcare professional if you have any concerns about your menstrual cycle or if you experience any abnormal bleeding or other symptoms.

There are more.

Our drives have cycles and frequencies.

1. Survival: The drive to stay alive and protect oneself from harm is associated with the release of beta brain waves (14-30Hz) which are associated with alertness, attention and decision making.

2. Reproduction: The drive to reproduce and continue the species is associated with the release of alpha brain waves (8-13Hz) which are associated with feelings of relaxation, calm and increased creativity.

3. Social interaction: The drive to connect with others and form relationships is associated with the release of theta brain waves (4-7Hz) which are associated with deep relaxation, emotional connection and empathy

4. Power: The drive to exert control and influence over others is associated with the release of beta brain waves (14-30Hz) which are associated with alertness, attention and decision making.

5. Curiosity: The drive to explore and learn about the world around us is associated with the release of alpha brain waves (8-13Hz) which are associated with feelings of relaxation, calm and increased creativity.

6. Aesthetics: The drive to seek out beauty and pleasure is associated with the release of alpha brain waves (8-13Hz) which are associated with feelings of relaxation, calm and increased creativity.

7. Self-actualization: The drive to reach one's full potential and to achieve self-fulfilment is associated with the release of theta brain waves (4-7Hz) which are associated with deep relaxation, emotional connection and empathy

8. Self-preservation: The drive to protect oneself and maintain physical and emotional well-being is associated with the release of delta brain waves (0.5-4Hz) which are associated with deep sleep, healing and rejuvenation.

The most obvious cycles earth creatures, including humans, have to adapt to is the solar and lunar cycles.

The solar cycle, also known as the sunspot cycle, is the pattern of variation in the number and size of sunspots on the surface of the sun. Sunspots are areas of intense magnetic activity that appear darker than the surrounding surface. The solar cycle typically lasts around 11 years, and it is characterized by a regular increase and decrease in the number of sunspots over time.

The solar cycle is caused by the interaction of the sun's magnetic field with its surface. The sun's magnetic field is generated by the movement of charged particles in the sun's interior, which creates complex patterns of magnetic activity on the surface. These patterns change over time, leading to the formation of sunspots.

The solar cycle is affected by several factors, including:

• The sun's internal dynamics: The sun's internal dynamics, such as the movement of charged particles in the sun's interior, play a key role in generating the sun's magnetic field and thus the solar cycle.

• Solar activity: The sun's activity, including solar flares, coronal mass ejections, and other forms of electromagnetic radiation, can affect the solar cycle.

• The sun's rotation: The sun rotates on its axis, and this rotation can affect the distribution of sunspots and the solar cycle.

• Interplanetary magnetic field: The solar cycle is also affected by the interplanetary magnetic field, which is the magnetic field that exists throughout the solar system and is created by the solar wind.

The solar cycle affects Earth's environment, It can influence the auroras, satellite and power grid operations, and space weather which can cause damage to technology in space or on the ground. Solar flares and coronal mass ejections can also affect Earth's ionosphere and the radiation environment around Earth.

It's important to note that the solar cycle is a complex and dynamic process that is not fully understood, and the accurate prediction of solar activity is a challenging task. Scientists continue to study the solar cycle in order to better understand its causes and effects.

The sun illuminates whatever its light falls upon. 

We synchronise our day with sunlight, we synchronise our night with the moonlight.  In ancient times we could see and hunt by the light of a full moon so the lunar cycle had a direct impact on our organisation of time. Many of us have messed up our natural cycles when we inappropriately introduced artificial light at times of natural darkness.

The lunar cycle, also known as the lunar month or synodic month, is the period of time it takes for the moon to complete one full orbit around the Earth and return to the same phase. The lunar cycle typically lasts 29.5 days, and it is characterized by a regular sequence of phases, including new moon, crescent moon, first quarter, gibbous moon, full moon, and last quarter.

The lunar cycle is primarily caused by the gravitational interaction between the Moon and the Earth. The gravitational pull of the Moon causes the tides on Earth and it is also responsible for the 29.5-day cycle of the Moon's phases. The Moon's orbit around the Earth is not a perfect circle, but an ellipse, so the time it takes for the Moon to orbit the Earth can vary slightly.

The lunar cycle is affected by several factors, including:

• The gravitational pull of other celestial bodies, such as the Sun, which affects the Moon's orbit.

• The axial tilt of the Moon, which causes the amount of sunlight that reflects off the Moon's surface to vary over time.

• The angle of the Moon's orbit relative to the Earth, which affects the visibility of the Moon's phases.

• The lunar libration, which is the small oscillation in the position of the Moon as it orbits the Earth.

The lunar cycle affects several aspects of life on Earth, such as the tides, which are caused by the gravitational pull of the Moon. The lunar cycle also has a cultural and religious significance for many people, and it is often used to track time, plan agricultural activities and mark festivals and ceremonies.

It's important to note that the lunar cycle is a well-understood process, and the timing of the lunar phases can be predicted with great accuracy.

One day on earth is one complete rotation of the earth on its axis regardless of earths position in orbit around the sun.

  At the equator the time of light remains equal to the time of dark throughout the year. As we move away from the equator the balance of light and dark in a day varies throughout the year; there are seasons.  Humans know these natural patterns and adapt practices to benefit from the knowledge.

One year on earth is one complete orbit of the earth around the sun. 

Earth orbits the Sun at an average distance of 149.60 million km (92.96 million mi) in a anti-clockwise direction as viewed from above the Northern Hemisphere. One complete orbit takes 365.256 days (1 sidereal year), during which time Earth has travelled 940 million km (584 million mi). Earths orbital speed through space is about 18.5 kilometres per second relative to the sun.

Heartrate and circulation is a well known cycle that adapts to our needs.

Cycles of the brain and body.

From the beginning we learn by trial and error but as we develop and understand more we can copy better practices from others.

If I want to learn something I seek out the information. I could set up an experiment and find results for myself or I could read what happens when someone else does that experiment.

I can also copy mannerisms that I witness as successful.

Some people give very good examples, it is up to our judgement as to which examples we think are a good fit for ourselves.

Mentors are ideal to acquire quality experience. 

Table 1.

The majority of the values presented in the above table are a range of values due to the inter-variability inherent to human beings, that is, the some organ, but in different subjects, have different resonance frequencies. Sometimes, the same organ, in the same subject, can also have different values depending on the circumstances due to the intra-variability of the results. Nevertheless, the frequencies presented in Table 1 may be used to interpret results obtained during whole-body vibration studies.
