Was it around the age of 25 when you started to feel tired?
Adolescence is the time when everything is fresh and you want to experience many things. It is a time when you can move around all day long without getting tired, but eventually at some point, you begin to feel tired. What age does that usually happen?
Most people do not feel tired until they reach age 25, when they are in full physical strength. There are many factors related to aging. Since various environments and diseases are involved, it is difficult to pinpoint when exactly people begin to feel tired, but if we focus on melatonin secretion, we can look at its relationship to aging.
Melatonin is a well-known hormone involved in sleep. It is a hormone secreted from the pineal gland, which is located in the interbrain of the brain, and is related to the regulation of the body clock, enhancement of immunity and antioxidant properties, and anti-cancer and anti-aging effects. Melatonin is secreted rapidly from birth and reaches its peak in the late teens. It is believed that even if you continue to lead an irregular lifestyle or engage in strenuous activities, you won’t feel tired because you are secreting a lot of melatonin. Melatonin levels drop significantly from the early 20s, and by the age of 25, melatonin levels are less than half of what they were previously and around the age of 26, people begin to feel occasional fatigue. When you feel fatigue gradually increases in frequency from the age of 27 onward. After this point when people are tired, they will need to get enough sleep to get rid of the fatigue. It is thought that the amount of melatonin secretion may be involved, making the body more susceptible to fatigue.
The nine years between the ages of 25 and 34 are the turning point for our physical strength!
Although it is not possible to specify at what age fatigue begins to be felt, some tendencies can be seen by examining various surveys. In most cases, people begin to feel it slightly more around age 25, and by their late 20s or early 30s more than half of both men and women are aware that it’s harder to resolve their tiredness.
A 2019 study conducted at Stanford University in the United States tells us that the data can be read from the plasma proteins in the blood to determine the body’s aging rate. Plasma is the liquid in blood minus the red blood cells, white blood cells, and platelets, made up of proteins and electrolytes. It tells us that about 400 kinds of those plasma proteins are associated with aging, and that 30% of them change in an irregular pattern as we age, with major peaks at ages 34, 60, and 78.
In Eastern thought, the cycle of life is considered to be 9 years. In other words, the turning point of physical strength decline is between the ages of 25 and 34. Based on our clinical experience, it seems that physical fitness declines over a period of about nine years. Since these days this is a busy generation, it is important to get a good night’s sleep and avoid serious illnesses that may cause severe physical strength decline.
