Hair and nails grow for some time after death

MYTH

This myth is in fact just an optical illusion. Indeed, nails and hair of the departed seem to be longer. The cause of it is not the fact that they have grown. Namely, after death human body dehydrates and the skin shrinks. In effect, the skin covering hands, feet and head "draws back" and exposes the better part of a nail plate than during life. The analogical process occurs on the head. To sum up, these are not nails and hair which grow, but the skin which slips off them. 

The most important garment in the wintertime is a cap

MYTH

This myth can be broken up into two more detailed myths. The first one says that most of the human body heat escapes through the head and another tells us that we can easly catch a cold in a frosty air.
First of all, the same amount of air escapes through the head as through any else part of our body. If this myth was true, we could run in the winter clothed in caps and short sleeves, and we would not feel cold. Furthermore, the cold is brought on by viruses which can be found both in the warm and cold air. There is even the theory saying that people more often are ill in winter, since they remain in closed buildings and infect one another. Thus, when spending time in the cool air, we have to beware of exosure rather than viruses!

Reading in dim light hurts our eyes

MYTH

Each and every one of us must have heard this just for once in life from parents, grandmother or anyone else when reading in a poorly lit room. Luckily for fans of reading by candlelight, the lack of suitable light does not cause any enduring effects for the eyesight. There can appear the eye fatigue or excessive desiccation of the eyeball bacause of limited incidence of blinking in dim light, indeed. Nevertheless, these afflictions are of short duration and dissapear as soon as we let our eyes relax. Despite appropriate testings which have been conducted, there are no prooves that reading in dim light can anywise affect the eyesight and cause irreparable changes in the structure of eyes leading to vision defect.
