Determinación y cognición de PHS en el diseño humano: alimentando el cuerpo y la mente

What Is PHS (Primary Health System)?

PHS is the optimal nutrition system in Human Design, based on the Color and Tone of the Design Sun. This isn't a diet in the classical sense — it's the mechanics of how your specific body best assimilates food and converts it into energy.

Ra Uru Hu discovered PHS as a practical tool for beginning the deconditioning experiment. The logic is simple: if the body isn't working correctly due to improper nutrition, the mind cannot be clear, and no authority will function properly.

6 Determination Types

Determination comes from the Design Sun's Color. Each Color has two variants — left (active) and right (passive), giving 12 types:

Color 1 — Appetite

• Left (Consecutive): need to eat the same things at the same times. The body thrives on stable routine. Breakfast at 8, lunch at 1, dinner at 7 — every day.
• Right (Alternating): need variety. Never eat the same thing two days in a row. The body is stimulated by novelty.

Color 2 — Taste

• Left (Open): food should be simple, with minimal ingredients. Mono-meals, simple recipes, clean flavors.
• Right (Closed): complex dishes, many ingredients, complex flavors. The body needs culinary complexity.

Color 3 — Thirst

• Left (Hot): hot food and drinks. The body better assimilates warm food.
• Right (Cold): cold food and drinks. Raw products, salads, chilled food.

Color 4 — Touch

• Left (Calm): need quiet and peace while eating. No TV, no conversation, full attention on food.
• Right (Nervous): need stimulation while eating — conversation, TV, reading. Paradoxically, this improves digestion.

Color 5 — Sound

• Left (High frequency): the body works best when food is paired with high-frequency sounds — classical music, nature sounds.
• Right (Low frequency): low-frequency vibrations during meals — deep voice, bass music, or silence.

Color 6 — Light

• Left (Direct light): eat in bright lighting, preferably daylight. Sunlight stimulates digestion.
• Right (Indirect light): eat in soft, diffused light. Candles, dim light, or even darkness.

12 Cognition Types

Cognition is determined by the Personality Sun's Tone and describes how your mind best processes information:

• Smell (Tone 1) — a "nose" for the right information. Instinctive knowing whether something is correct or not.
• Taste (Tone 2) — "tasting" information. Need to sample a topic before diving deep.
• Outer Vision (Tone 3) — need to see the big picture. Learning through observation, visual materials.
• Inner Vision (Tone 4) — focus on details. Need to "see" within, meditative approach to information.
• Feeling (Tone 5) — learning through tactile experience. Need to "touch," try in practice.
• Sound (Tone 6) — acoustic cognition. Learning through listening, audiobooks, lectures, conversations.

Each cognition also has a left (focused) and right (peripheral) variation, giving 12 types total.

How to Begin the Experiment?

Calculate your bodygraph and pay attention to the upper Variable arrows. Start with Determination — change your eating conditions according to your type and observe changes over 3-6 months. Then add the Cognition experiment.

"PHS is the gateway to deconditioning. Without proper nutrition, the body cannot support consciousness in its correct state." — Ra Uru Hu
