Skip navigation! Story from Body. Kelsey Miller. We all have our little bugaboos. Some people hate their "crooked" noses and others bemoan their "weak" ankles. Remember that scene in Mean Girls? What started with a casual comment about my difficulty finding a hat that fits turned into an echo of agreement throughout the office, and soon devolved into a dog-pile of big-head havers insisting that, no, their noggin's really huge.
But, like, I really do have a big head, you guys. Hats sit atop my giant melon like the cherry on a sundae. If I do manage to jam the thing down, it will slowly slip up the sides of my hair, buckling against the mammoth circumference of of my skull, and finally fall to the floor.
But, when no fewer than 27 of my coworkers responded to my "Do you have a big head? Or ahead. There was! The national average is estimated to fall between 22 and 23 inches, but there is no current government data on adult head size. Science has other stuff going on, guys. But, there is at least one head-related profession that's sure to have the facts: hatmakers. I called on Molly Yestadt of Yestadt Millinery to see if she'd heard this complaint before.
Instantly, she replied: "I hear it all the time. Often, it's not actually true. So, was it us, or were the hat and sunglass industries engendering this new form of body dysmorphia? But that's actually kind of small. I make some of my samples 23 inches. If you can fit into a sample, you don't have a gigantic nog. But, we haven't even considered evolution. Yestadt explains that "people are bigger in general," these days. Think about it. How many people can fit into their grandmother's clothing?
Yet, we all continue to see gigantic domes facing us in the mirror. So, I rounded up 14 staffers who claimed to suffer from this affliction myself included. I asked each participant to explain their experience of big-headedness — their woeful tales of too-tight glasses and moon-faced selfies. Then, I whipped out a measuring tape to see where we really stack up.
As suspected, we are all head-orexic. Here, you'll see 14 otherwise intelligent women explaining a problem they do not have — and the math that proves it. Now, you can put a lid on those outsize-cranium concerns. The U. It's almost fall, which means that in addition to pumpkin spice lattes and sweater weather, it's time to brace for ragweed season.

Nothing makes you re-examine your life quite like completely surrendering to nature as you tuck-and-roll out of a plane at 10, feet.
However, I. You know that game where you scream "penis" at the top of your lungs? Yeah, that's. Thanks to the much-needed noise around period poverty in recent years, we're increasingly aware of the fact that, for many women, sanitary products aren't. So, you have a urinary tract infection. By now, you've probably heard a thing or two but probably more about CBD, the breakout wellness ingredient that everyone's obsessed with.

Clinicians measure head circumference by measuring your child's head at the widest part. When you encircle the head with a tape measure, you arrive at the head circumference. During the first year of life, your baby's head circumference normally grows from between Between 6 months and 2 years of age, according to MedlinePlus, the two measurements become equal.
It's easy to see, looking at a baby, that his head is usually disproportionately large compared to older children and adults. A baby's head circumference increases dramatically during his first year, normally by around 33 percent, because his brain will have more than doubled in weight, according to Theis. Most brain growth occurs in the first two years of life; a normally increasing head circumference indicates normal brain growth and maturation. Between ages 1 and 2, a child's head circumference increases by just 1 inch as his proportions become more adultlike, Theis reports.
He'll be 17 years old before his head circumference reaches maturity, at around If your baby's head circumference grows faster than normal -- a condition called macrocephaly -- your doctor will also look for a cause.
WHO | Head circumference-for-age
In human anatomy, the head is at the top of the human body. It supports the face and is maintained by the skull , which itself encloses the brain. The human head consists of a fleshy outer portion, which surrounds the bony skull.
The brain is enclosed within the skull. The head rests on the neck , and the seven cervical vertebrae support it. The human head typically weighs between 5 and 11 pounds 2.
The face is the anterior part of the head, containing the eyes , nose , and mouth. On either side of the mouth, the cheeks provide a fleshy border to the oral cavity.
The ears sit to either side of the head. The head receives blood supply through the internal and external carotid arteries. These supply the area outside of the skull external carotid artery and inside of the skull internal carotid artery. The area inside the skull also receives blood supply from the vertebral arteries , which travel up through the cervical vertebrae. The twelve pairs of cranial nerves provide the majority of nervous control to the head.
The sensation to the face is provided by the branches of the trigeminal nerve , the fifth cranial nerve. Sensation to other portions of the head is provided by the cervical nerves. Modern texts are in agreement about which areas of the skin are served by which nerves, but there are minor variations in some of the details. The borders designated by diagrams in the edition of Gray's Anatomy are similar but not identical to those generally accepted today.
The head contains sensory organs : two eyes, two ears, a nose and tongue inside of the mouth. It also houses the brain. Together, these organs function as a processing center for the body by relaying sensory information to the brain. Humans can process information faster by having this central nerve cluster. For humans , the front of the head the face is the main distinguishing feature between different people due to its easily discernible features, such as eye and hair colors, shapes of the sensory organs, and the wrinkles.
Humans easily differentiate between faces because of the brain's predisposition toward facial recognition. When observing a relatively unfamiliar species, all faces seem nearly identical. Human infants are biologically programmed to recognize subtle differences in anthropomorphic facial features. People who have greater than average intelligence are sometimes depicted in cartoons as having bigger heads as a way of notionally indicating that they have a "larger brain".
Additionally, in science fiction , an extraterrestrial having a big head is often symbolic of high intelligence. Despite this depiction, advances in neurobiology have shown that the functional diversity of the brain means that a difference in overall brain size is only slightly to moderately correlated to differences in overall intelligence between two humans. The head is a source for many metaphors and metonymies in human language , including referring to things typically near the human head "the head of the bed" , things physically similar to the way a head is arranged spatially to a body "the head of the table" , metaphorically "the head of the class" , and things that represent some characteristics associated with the head, such as intelligence "there are a lot of good heads in this company".
Ancient Greeks had a method for evaluating sexual attractiveness based on the Golden ratio , part of which included measurements of the head. Headhunting is the practice of taking and preserving a person's head after killing the person. Headhunting has been practiced across the Americas, Europe, Asia, and Oceania for millennia. In many cultures, covering the head is seen as a sign of respect.
Often, some or all of the head must be covered and veiled when entering holy places or places of prayer. For many centuries, women in Europe, the Middle East , and South Asia have covered their hair as a sign of modesty. This trend has changed drastically in Europe in the 20th century, although is still observed in other parts of the world.
In addition, a number of religions require men to wear specific head clothing—such as the Islamic Taqiyah cap , Jewish yarmulke , or the Sikh turban. The same goes for women with the Muslim hijab or Christian nun's habit. A hat is a head covering that can serve a variety of purposes. Hats may be worn as part of a uniform or used as a protective device, such as a hard hat , a covering for warmth, or a fashion accessory.
Hats can also be indicative of social status in some areas of the world. While numerous charts detailing head sizes in infants and children exist, most do not measure average head circumference past the age of Reference charts for adult head circumference also generally feature homogeneous samples and fail to take height and weight into account.
Macrocephaly can be an indicator of increased risk for some types of cancer in individuals who carry the genetic mutation that causes Cowden syndrome. For adults, this refers to head sizes greater than 58 centimeters in men or greater than 57 centimeters in women. Human head. From Wikipedia, the free encyclopedia. Upper portion of the human body.
