High living standards make nails grow faster

Along with the increasing living standard, the human body also has many changes, the growth of toenails and nails also tends to grow faster.

In the latest study by American scientists, compared with 70 years ago, the growth rate of toenails and fingernails has increased by a quarter, in which improvement of eating conditions plays a role. important game.

Researchers at the University of North Carolina USA conducted a study on the growth rate of toenails and fingernails, the results of which were published in the European Society of Venereal and Dermatology Society (EADV) in Recent issues.

After observing the growth rate of 195 fingernails and 188 toenails, and conducting comparisons with similar research data in 1938 by the Oxford University of England, researchers discovered fingernails and toenails. The speed of development has become a trend.

Research shows that at present , the toe toe has an average growth rate of 2mm months, while the research data in the last 30 century is 1.65mm months .

Today, thumb nails have a growth rate of 3.35mm months, 30 and 50 years old in the last century respectively 3 and 3.06mm months, only within 70 years increased by about 0.5mm.

The study also points out that the nail growth rate of humans is not the same, the fastest finger middle finger grows, the index finger grows the slowest. In general, the average nail size is 3.47mm, twice the growth rate of the toenails.

The life has changed

With the results of the study, researchers believe that improving people's eating conditions plays an important role.

In the past, people used carbohydrate-rich foods like potatoes, bread, etc., which were relatively low in protein. Meanwhile, food today is rich in protein such as fish, meat, eggs and poultry.

Teresa Smith, a manicurist, said: ' Nails are becoming longer and longer, mainly due to the adequate and balanced human diet, while people have clear perceptions. More about nutritional needs for yourself. '

In addition to diet, other causes also play an important role in the development of nails.

' A lot of sun exposure will also promote nail growth ,' Smith said. ' In the summer, people often drink more water, which has the effect of eliminating toxins that make the body healthy and healthy. Of course, it will make nails grow better. '

Research has also shown that nail growth rates in each person are different, for example: youth's nail growth rate is faster than that of the elderly and men than women.

Trend

Not only do nails and toenails grow fast, but other parts of the body also have such phenomena.

Researchers said: ' The weight of human being at birth, the growth rate, adolescents and the trend of weight gain of adults has been proven. Our research shows that the growth rate of nails and toenails is also increasing rapidly. '

Scientists explained to reporters on the British Mail on Sunday: '30 years ago, whether the environment, mode of life or health status all lead to big changes, this creates The corresponding change in human diet, body activity and physical state . '

Scientists have discovered that the first part of children born in the UK is getting bigger and bigger. Compared to 1930 and 1985, the first part of 1-year-old children in the UK increased by 1.5cm.
