As people age, the aging process is often accompanied by: graying hair, decreased visual and visual ability, slower reactions, sagging skin, and increased blood pressure. In fact, there are some unnoticed signs of aging in various organs of the human body.

Massive hair loss, rising hairline

Hair ages in the form of graying hair, hair loss, and especially an upward movement of the hairline.

The thick hair in the past, with the increase of age, the decline of kidney function, and the decrease of estrogen have led to a large amount of hair loss in many middle-aged women, which often indicates that female aging is coming. If your hair volume is still thick after the age of 40, it means that your physical condition is still relatively young.

Decreased gastric motility

With the advent of aging, people will obviously feel that the gastric motility decreases after eating, the intestinal peristalsis ability is weakened, and sometimes they will feel indigestion, bloating and constipation after eating, which are related to the decline of gastrointestinal muscles.

The soles of the feet become larger

As we age, the plantar muscles and ligaments undergo degenerative changes, the arch of the foot collapses, the elasticity is lost, and the tendons and ligaments connect the tiny bones lose their elasticity, and the foot becomes longer and wider.

The gap between the teeth becomes larger

After the age of 40, the teeth and tongue will slowly age. In terms of teeth, there are mainly gum recession, tooth sensitivity, loose teeth, and taste loss in the tongue.

When a person's gap between teeth starts to widen and becomes wider, it is a sign that there is a problem with the teeth, either due to gum recession or inflammation around the gums.

Heart signals

As we age, our heart function will also decline, and sometimes we will feel that our heart is beating violently and we can't breathe when we exercise a little, and in severe cases, we will induce angina pectoris and arrhythmia, which are all signs of heart aging.

Decreased sexual performance

To evaluate whether a man is old, passion is an important reference criterion.

Male sexual dysfunction includes decreased libido, penile erectile dysfunction (ED), orgasm and ejaculatory dysfunction, among which ED is the most common male sexual dysfunction. Surveys have shown that about 3% of adult men have erectile dysfunction, and the incidence increases with age. More than half of men after the age of 0 years may suffer from ED. Premature ejaculation is the most common ejaculatory dysfunction, accounting for more than 0/0 of adult men.

Presbyopia

Presbyopia is the natural aging of the eyes, and the prescription increases with age. After the age of 40, the elasticity of the lens of the eye will gradually decrease, and the ability of the ciliary muscle to regulate will decrease, so presbyopia will begin to appear.

Bone spurs are present

Bone spurs, like human wrinkles, are a natural manifestation of aging in the human body. As we age, the articular cartilage degenerates, and "bone spurs" develop.

Brain aging begins at this age

A longitudinal study of people aged 10-0 years showed a linear trend in cognitive decline every 0 years.

A study published by a research team from Capital Medical University in the journal Nature pointed out that if the average life expectancy is calculated according to the age of 72, brain aging begins to occur around the age of 0, and brain aging accelerates around the age of 0, showing "cliff-like" degeneration.

10 years before the brain ages, the hands and feet send signals

　　2024年5月，发表在柳叶刀子刊《柳叶刀-老龄健康》的一项研究表明，大脑老化前，手和脚就会发出信号，最早在10年前就有征兆。

The study found that in older adults, there was a decline in overall cognitive ability and motor function (gait function and hand strength). Moreover, the decline in gait function and hand strength preceded the decline in cognitive ability by up to 10 years.

Changes in hand strength and gait can help detect disease early

Interestingly, hand strength is more associated with the performance of brain aging than a decline in gait function. However, large-scale cerebral infarction is more closely associated with gait decline.

The final study found that "declining hand strength" may help identify the risk of Alzheimer's disease; "Gait decline" may be a biomarker of early vascular cognitive impairment. Therefore, paying attention to changes in walking posture and grip strength can help detect signs of illness early. (Comprehensive Health Times, Popular Science China, Health News, etc.)

Spotlight New research reveals why humans love carbs at the genetic level

　　如果您发现在日常饮食中减少摄入碳水化合物非常困难，那么可能是古老的DNA在作祟。据新华社报道，美国研究人员近日发表论文说，唾液淀粉酶基因（AMY1）在人体内的最初复制可能早在80多万年前就已经发生，远远早于农业出现。该基因拷贝数的变异为人类适应富含淀粉的食物提供优势。相关研究成果在线发表于美国《科学》杂志。
