Yes, early humans (often called cavemen) definitely had lice, and genetic studies of lice have revealed crucial details about human evolution, showing that modern humans likely caught head lice from archaic human relatives like Neanderthals when they interbred, providing evidence of direct contact and shared ancestry. Lice have been with humans for millions of years, with pubic lice even coming from gorillas, indicating lice are key to understanding our ancient past.
New research indicating early humans acquired public lice from gorillas about 3.3 million years ago sheds new light on when humans started to lose their body hair as they migrated out of the trees and onto the savannah.
Throughout ancient Egypt, people were tormented with lice. Remedies for the common person included eating a special meal mixture with warm water, and then vomiting it up. Others believed a recipe of spices mixed with vinegar rubbed on the scalp over a few days would suffocate them out.
Our ancestors may have caught nits from their primitive cousins. Humankind's inexorable spread across the globe may have had an unwelcome side-effect - it brought us face to face with our ancient hominid relatives just long enough to catch their head lice.
Getting head lice isn't a sign of poor hygiene or unclean surroundings. Head lice prefer clean hair to attach and lay their eggs. Another common misconception is that head lice can jump or fly from one person to another. Head lice only crawl, most often leading to transmission through direct head-to-head contact.
However, do lice attracted to a certain hair type? The answer to that is no; they will go to any head that has hair available. Children with coarse curly hair may actually have an inadvertent advantage: using more products and washing less often.
Lice dislike the aroma of peppermint, hence its function as a repellent; however, peppermint is not harmful to lice. To kill lice, a substance must enter the breathing mechanism and remain there for long to strangle them. There are more effective alternatives to peppermint oil that can be used in killing lice.
Head lice have been around for a long time. Genetic studies suggest that lice developed about 1.68 million years before homo sapiens emerged, and that they started their relationships with humans about the same time human evolution separated from chimpanzee evolution.
Head lice infestation is most often caused by direct contact with these insects. Head lice are a tan or gray insect about the size of a sesame seed. The female louse sticks each egg to the base of a hair shaft less than 1/8 inch (3 millimeters) from the scalp.
Lice are most common in kids ages 3 to 12, as they're usually in frequent, close contact with each other. Lice don't have wings, but they'll crawl between people and live in warm areas of your body, like on your head. Adult lice lay eggs near your scalp and glue them to your hair.
Ancient Head Lice Treatments
The Egyptians often shaved their heads clean and the beautiful long locks we see in pictures were wigs. If you became infested with head lice, the Egyptians treated themselves with an aromatic head lice formula made of water, vinegar, oil of cinnamon, oil of rosemary, oil of terebinth.
Common misconceptions about medieval hygiene
However, this idea is far removed from historical reality. In fact, there was an awareness of personal hygiene and cleanliness in the Middle Ages. Public bathhouses could be found in many towns and regular bathing was quite common among certain social classes.
Although not as common, head lice may spread by: Wearing clothing, such as hats, scarves, coats, sports uniforms, or hair ribbons worn by an infested person. Using infested combs, brushes, or towels. Lying on a bed, couch, pillow, carpet, or stuffed animal that has recently been in contact with an infested person.
Head lice seem to be more common in Caucasian, Hispanic, and Asian American people than in African American people. For example, fewer than 0.5% of African American schoolchildren experience head lice compared with about 10% of schoolchildren of other races.
Early modern remedies were based on humoral theory or methods of suffocation, poisoning, and containment. All six lice treatments in The Vermin Killer (1680) included ingredients such as hog lard, butter, smashed apple, olive oil, or wax; these would have suffocated or immobilised the lice.
Exposing lice and nits to temperatures above 125 degrees F for 10 minutes is lethal. Most personal articles of clothing and bedding can be disinfested by machine washing in hot water or machine drying for at least 20 minutes using the hot cycle.
(Phthiraptera: Pediculidae), on feeding success, longevity and numbers of eggs laid were investigated using an artificial blood-feeding system in the laboratory. No significant differences were found between lice fed on different human blood types for any of the parameters tested.
