Hood (headgear) in the context of "Weatherhead"

Academic dress is a traditional form of clothing for academic settings, mainly tertiary (and sometimes secondary) education, worn mainly by those who have obtained a university degree (or similar), or hold a status that entitles them to assume them (e.g., undergraduate students at certain old universities). It is also known as academical dress, academicals, or academic regalia.

Contemporarily, it is commonly seen only at graduation ceremonies, but formerly academic dress was, and to a lesser degree in many ancient universities still is, worn daily. Today, the ensembles are distinctive in some way to each institution, and generally consist of a gown (also known as a robe) with a separate hood, and usually a cap (generally a square academic cap, a tam, or a bonnet). Academic dress is also worn by members of certain learned societies and institutions as official dress.

A cloak is a type of loose garment worn over clothing, mostly but not always as outerwear for outdoor wear, which serves the same purpose as an overcoat and protects the wearer from the weather. It may form part of a uniform. People in many different societies may wear cloaks. Over time, cloak designs have changed to match fashion and available textiles.

Cloaks generally fasten at the neck or over the shoulder, and vary in length from the hip to the ankle, with mid-calf being the normal length. They may have an attached hood and may cover and fasten down the front, in which case they have holes or slits for the hands to pass through. However, cloaks are almost always sleeveless.

A snood (/snuːd/) is a type of traditionally female headgear, with two types known. The long-gone Scottish snood was a circlet made of ribbon worn by young Scottish women as a symbol of chastity. In the 1590s, snoods were made using Florentine silk ribbon for the gentlewomen at the court of Anne of Denmark by Elizabeth Gibb.

The other type was intended to hold the hair in a cloth or net-like hat. In the most common form, the headgear resembles a close-fitting hood worn over the back of the head. It is similar to a hairnet, but snoods typically have a looser fit.

Fashion in 15th-century Europe was characterized by a surge of experimentation and regional variety, from the voluminous robes called houppelandes with their sweeping floor-length sleeves to the revealing giornea of Renaissance Italy. Hats, hoods, and other headdresses assumed increasing importance, and were draped, jeweled, and feathered.

As Europe continued to grow more prosperous, the urban middle classes, skilled workers, began to wear more complex clothes that followed, at a distance, the fashions set by the elites. It is in this time period that fashion took on a temporal aspect. People could now be dated by their clothes, and being in "out of date" clothing became a new social concern. National variations in clothing seem on the whole to have increased over the 15th century.

Sensory deprivation or perceptual isolation is the deliberate reduction or removal of stimuli from one or more of the senses. Simple devices such as blindfolds or hoods and earmuffs can cut off sight and hearing, while more complex devices can also cut off the sense of smell, touch, taste, thermoception (heat-sense), and the ability to know which way is down. Sensory deprivation has been used in various alternative medicines and in psychological experiments (e.g. with an isolation tank). When deprived of sensation, the brain attempts to restore sensation in the form of hallucinations.

Short-term sessions of sensory deprivation are described as relaxing and conducive to meditation; however, extended or forced sensory deprivation can result in extreme anxiety, hallucinations, bizarre thoughts, and depression.

A parka, like the related anorak, is a type of coat with a hood, that may be lined with fur or fake fur. Parkas and anoraks are staples of Inuit clothing, traditionally made from caribou or seal skin, for hunting and kayaking in the frigid Arctic. Some Inuit anoraks require regular coating with fish oil to retain their water resistance. Parkas are typically longer, often extending to the thighs or knees. Anoraks are usually shorter than parkas, often hip-length, and are traditionally a pull-over jacket.

The words anorak and parka have been used interchangeably, but they are somewhat different garments. Strictly speaking, an anorak is a waterproof, hooded, pull-over jacket without a front opening, and sometimes drawstrings at the waist and cuffs, and a parka is a hip-length cold-weather coat, typically stuffed with down or very warm synthetic fiber, and with a fur-lined hood.

A coat is typically an outer garment for the upper body, worn by any gender for warmth or fashion. Coats typically have long sleeves and are open down the front, and closing by means of buttons, zippers, hook-and-loop fasteners (AKA velcro), toggles, a belt, or a combination of some of these. Other possible features include collars, shoulder straps, and hoods.
