Homo sapiens are naked, hairless, sweaty apes with big brains and this is how we evolved to live:

  1. Wake up with the first light of the day.
  2. Watch the sunrise.
  3. During daylight eat one (maybe two) meal of local seasonal fresh food including a large amount of seafood.
  4. Be naked in the sun and barefoot on the earth all day.
  5. Swim in the ocean.
  6. Do moderate exercise collecting food and fresh drinking water
  7. In the hottest part of the day seek shade and rest.
  8. In afternoon potter around.
  9. Watch the sun set.
  10. Go to sleep on the earth in darkness.

Humans lived every day like this on the East African rift for 300 000 years in perfect synchrony with the daily and seasonal rhythms of the sun, the earth, the moon and stars. Humans absorb light, store light, use light, convert light and release light. Every aspect of human cellular function adapted to efficiently harvest energy from the sunlight, magnetic fields, water, marine DHA in this environment. This is the authentic human life. Living this way will keep you healthy into old age. Any change or variation to this daily routine will subtract health from you. Why?

  1. Wake up with the first light of the day. Humans have detectors for light in the skin (melanopsin) that detect the first rays of morning light before sunrise and wake you up by releasing cortisol.
  2. Watch the sunrise. Sunrise and the all the varying frequencies of the morning sunlight are absorbed by the eyes and skin to build hormones, neurotransmitters and set the circadian rhythms of every cell in the body. Every sunrise is different, and cells pay attention to daily, monthly and seasonal variations.
  3. During daylight eat one (maybe two) meal of local seasonal fresh food including a large amount of seafood. One meal consumed during the day allows for beneficial intermittent fasting for the rest of the day and ketosis at night during sleep. Humans evolved larger brains and immune systems than our primate ancestors using the DHA & iodine from the marine food chain that humans adapted to eat. The availability of fruits and vegetables varies with the seasons. Photosynthetic food is information for your cells about the seasons.
  4. Be naked in the sun and barefoot on the earth all day. Humans are hairless primates to increase the amount of sunlight the skin absorbs – all frequencies of visible sunlight to make hormones, vitamin D, neurotransmitters, Vitamin A, molecular hydrogen and oxygen. Humans properly exposed to sunlight get 2/3 of energy from sunlight and just 1/3 from food. Covering the solar panel reduces the energy that melanin can produce. Humans have sweat glands in their hands and feet to increase the conductivity of the free electrons from the earth’s magnetic field. Every cell in the body tunes to the earth’s magnetic field (7.83 Hz).
  5. Swim in the ocean. Homo sapiens are aquatic apes that evolved to eat seafood. Swimming in the ocean provides another source of free electrons.
  6. Do moderate exercise collecting food and fresh drinking water. Humans have a great need for a daily supply of fresh clean drinking water. The human body is 60% water and water molecules make up 99% per volume of the cells inside us. Water inside us is a repository for light and forms a battery of electrons, photons and protons that are transported around the body for use in cells. Dehydration is a serious health issue.
  7. In the hottest part of the day seek shade and rest. Just like all the other animals in the wild.
  8. In the afternoon collect what you need for the following morning. Just potter around doing stuff.
  9. Watch the sunset. The eyes and skin pay attention to the waning frequencies of light at sunset to prepare the hormones of the body for sleep. The absence of light at night is a signal to facilitate regenerative sleep at night.
  10. Go to sleep on the earth in darkness. The absence of light is a very important signal for cellular circadian rhythms and metabolism. The earth’s magnetic field is stronger at night time than daytime and human cells that are connected to earth function at night time during sleep can vibrate at 100 Hz to fat burn (ketosis) and maintain growth and regeneration. Proper circadian sleep keeps cells healthy.

About 70 000 years ago humans began to migrate away from the equator to far flung places around the globe where the strength of sunlight varied with the seasons in contrast to the constant equatorial sunlight they had evolved with. In the cooler temperatures humans invented shoes, clothing and firelight.

This became our first mistake.

Clothing blocks the sun from our skin and this immediately reduces the amount of energy we can make from the action of sunlight, melanin and water that charge separates hydrogen and oxygen for cellular energy. This makes us more reliant on food for energy and increases metabolic rate and decreases lifespan. Clothing blocks the ability of the skin to make Vitamin D from UVB sunlight. Moving away from the equator also decreases the amount of UVB sunlight available throughout the day and year. Decreasing Vitamin D has many negative effects on the immune system and many other functions in the body.

In the weaker sunlight and colder temperatures many humans evolved changes to the melanin in their eyes, skin and hair to adapt to the new environments away from the equator. They evolved whiter skin, blue and green eyes, blonde and red hair that have different melanin that absorbs more sunlight. They evolved changes to their mitochondria that allowed them to increase their metabolic rate and make more heat in the colder climate and in the absence of strong sunlight. Humans ate more vitamin D containing fatty seafood (DHA) from cold ocean waters to offset the lack of sunlight away from the equator.

Firelight at night enabled us to stay awake longer after sunset and this was the first shift in our sleep patterns that is controlled by hormones we make via sunlight on the eyes and skin. Light after sunset is artificial light. The eyes and the skin detect this artificial light and it delays and reduces the effects of melatonin that is normally released after 4 hours of darkness and this reduces sleep quality and health. Human cells need the absence of light for proper function.

Shoes further disconnected humans from nature by putting a barrier between the human foot and the earth’s magnetic field reducing the ability of our atoms to align with the earth’s magnetic field and to collect free electrons from the earth.

Then humans began sleeping in houses raised off the earth and so they no longer aligned the atoms in their cells with the earth’s magnetic field and this reduced the efficiency of cellular functions. They invented candles and lamps and began living more of their lives at night time under artificial light and less in the daytime in the sunlight disrupting the circadian rhythms that controlled the health of their cells.

The industrial revolution was the first time that large numbers of humans came inside buildings to work in factories rather than working outside. In 1882 the electric power grid was invented and from this time onwards human health has been in rapid decline. Artificial lighting became readily available in buildings, streets and public places. More and more people began working inside rather than outside. Children went to school inside buildings. Television kept children inside after school rather than playing outdoors. Computers made that even worse. Then LED lighting really changed the frequencies of artificial light we were exposed to in our eyes and skin from light bulbs and screens. Artificial heating and cooling has detrimental effects on the seasonal circadian rhythms that our cells require for longevity. In just 136 years many new chronic degenerative diseases have emerged in humans and fertility has sharply declined.

The power grid, radio, television, radar, x-rays, microwave radiation are all manmade electromagnetic frequencies that affect our cellular function in negative ways. DNA expression depends on the electromagnetic signals from the environment. When these signals are foreign signals it changes the epigenetic expression of our DNA that results in misfolded proteins and changed optical signaling that causes diseases like autoimmune, cancer and neurodegeneration.

Misinformation about the dangers of sunlight to humans has been the number one piece of bad advice that has led to worldwide epidemic of low vitamin D, disrupted circadian cycles, poor sleep and diseases that have exploded in the last 130 years. Combined with a lack of daily darkness at night time the artificial light we are bathed in is ruining our health and fertility.

These days humans get hardly any sunlight in their eyes and skin. In the brief moments each day spent outside they wear hats, clothing, sunglasses, sunscreen, rubber soled shoes. Their eyes and skin don’t get exposed to the frequencies of sunlight they require to make water, oxygen, hormones and neurotransmitters required for healthy cellular regeneration during sleep. People crave food and drugs because they are undernourished from sunlight. People are tired all the time, but they cannot sleep because they cannot make the hormones they require to enter sleep. They are suffering multiple chronic diseases and so are their children. Autism was not described in the medical literature until 1943 in the USA. Mental illness and suicide are rampant. Cancer and neurodegenerative diseases are being diagnosed in younger and younger people. Humans have alarmingly high rates of infertility. Humans are the masters of their own extinction.

Humans no longer eat their species appropriate diet of marine seafood and they drink fluoridated water that reduces the battery capacity of water inside us. Every cell in the body requires DHA in the cell membranes to collect electrons and photons to turn sunlight into a DC electric current. Processed industrial foods lack DHA and contain high amounts of omega 6 fats that compete with omega 3 DHA for a place in the cell membranes. This decreases the energy we can collect and convert to useable energy and information for our cells and circadian rhythms. Processed foods do not contain the iodine, selenium, magnesium we need to run our hormones and cellular metabolism.

To reverse a disease, or avoid developing one, humans need to learn what is their species appropriate diet and lifestyle. That is the diet and lifestyle we evolved with in nature and it depends on the light, water and magnetism we evolved to use to run the 37 trillion cells inside us. The closer you can emulate your natural lifestyle and environment the less likely you will develop any disease.
