It’s no secret that head lice are disgusting. They can also shed some light on our human origins. They have evolved to fit around one single strand of hair. And their brains are not nearly as important as ours. The insects’ brains are largely comprised of hemolymph, which is the insect equivalent of blood. Lice feed several times per day, which makes it hard for them to survive without their host.
Head lice don’t live on people’s brains, but they are parasitic and feed on human blood. Unlike mosquitoes, they don’t spread disease. But it doesn’t mean they are harmless. You should be very careful when treating head lice. It’s possible to cure lice, but it’s not a pleasant experience.
Head lice symptoms usually take four to six weeks to appear, and more than half of those infested don’t show any symptoms. If you notice any of these symptoms in your child, treat him or her immediately. And don’t let your child share personal items with other people. Try to avoid having physical contact with people who may have head lice. If you’re worried about spreading the lice, you can also treat all of your family members.
If you think your child may have head lice, it’s important to get a medical diagnosis. There are nonprescription medications and home remedies you can try, but it’s always best to seek a professional opinion.
