Life Clock--Calcium Ion

When people reach middle age, they realize that the so-called "trace" ions in the blood are actually not insignificant at all. Sodium, potassium, calcium, phosphorus, and chlorine, like the notes on the stave, silently weave the melody of the human body. Among these ions, calcium is perhaps the most silent, profound, and life-revealing one.

In the past few years, I started swimming for an hour every day. From the initial insistence due to health anxiety and blood pressure, it gradually turned into a new understanding of the body, rhythm and life itself. With the recovery brought by exercise, I had many physical examinations and began to pay more attention to my blood calcium level - an indicator with a few decimal places that has been ignored for many years.

Until one day, I suddenly realized: Calcium ions are a display of a person's life cycle. It accompanies the formation of bones in the embryonic period and supports the growth and development of children; in adolescence, it is the basis for rapid bone proliferation; in adulthood, it maintains the conduction of electrical signals between nerves and muscles in the blood, regulating heartbeat and muscle contraction; in middle age, it slowly reduces its reserves and begins to show hidden signals of osteoporosis, fatigue, loose teeth, and night cramps; and in the later stage of life, the slow loss of calcium seems to announce the end of a physical cycle.

Calcium ions are structures, signals, and silent recorders. They are silent, but they witness every transition from prosperity to decline in life.

More precisely, calcium ions are the clock of human life，the annual rings of life. They do not move the second hand or sound the time, but they record the operating rhythm of age, metabolism, bones, nerves, and even the entire human system in the most basic way in the body.

Modern people live longer and longer, and their nutritional needs change accordingly. We think that a balanced diet and regular exercise are enough, but living in high latitudes with little sunlight, the body's vitamin D is quietly insufficient, and calcium is poorly absorbed.

Once upon a time, those reminders to "supplement vitamin D" and "supplement calcium" were just advertising slogans, but now, I also start to take a small piece of vitamin D every day to awaken the vitality of calcium ions and awaken my respect for the body.

Carefully maintain this "clock" to make your life more colorful.

May we all be able to understand the whispers of our bodies in every moment of our lives, and achieve true health through tiny repairs.
