Many people guarantee, “nails together”, that these and their hair grow faster during the summer months. What does science say?
Hair growth is influenced by several factors – genetics, age, hormones, nutrition are some. Seasonal changes seem to play a secondary role, but they are in this plot.
Some studies suggest that, including, grows faster in the hot months, and that the number of wires at rest, that is, those who are not growing or falling, hits the peak in late summer. Dermatologists cited by the believing that this may be due to increased blood circulation During the heat, which carries more nutrients to the hair follicles, promoting growth. But the impact is relatively small.
Hair grows, on average, less than half millimeter per day, so a seasonal increase of up to 60% is poorly noticeable. The differences observed may also be related to the perception: With lighter clothes and more exposed skin, small changes in hair growth become possibly more visible.
Nail growth has a slightly lighter pattern. They indicate that nails tend to grow faster in summer, possibly for the same circulatory reasons. THE Growth varies from finger to finger: It is usually faster on the middle and ring finger than in the thumb or pink, and can be affected by the dominant hand, injury or even disease.
The most detailed study of nail growth was conducted by the doctor William Beanwhich has done a self-observation over more than four decades, from 1941. He carefully measured the movement of brands in his nails every month. It also registered as diseases such as the bread could have growth, while the flu had a lighter effect.
The doctor noticed a Strong break in nail growth after 40 years. Surprisingly, although previous studies suggest seasonal effects, Bean found no differences in the growth of his nails between summer and winter. It has speculated that the modern lifestyle, with heating and air conditioning, may be reducing natural climate influence.
So, hair and nails grow faster in summer? The shorter and more direct answer is simbut very little. Environmental factors such as temperature can accelerate growth, but inner habits and perception probably amplify the impression.
