1. A headwear for cooling a wearer's head, comprising a cooling structure carrying a cooling agent, the cooling structure arranged for cooling the wearer's head and arranged to extend rearwardly past the wearer's internal occipital protuberance when the headwear is worn on the wearer's head, wherein the cooling structure comprises:
a first cooling portion configured such that when the headwear is worn on a the wearer's head it overlies the superior sagittal sinus, the first cooling portion configured to extend from the 4th cervical vertebrae through the rear of the superior sagittal sinus to the front of the superior sagittal sinus, wherein the first cooling portion has a width of between 50 mm and 60 mm and sets up a temperature gradient between the superior sagittal sinus and the area of the wearer's head adjacent the first cooling portion when the headwear is worn on the wearer's head; and
a plurality of secondary cooling portions that extend from the first cooling portion and are configured such that when the headwear is worn on the wearer's head they overlie the transverse sinuses wherein the plurality of secondary cooling portions each have a width of between 50 mm and 60 mm and set up a temperature gradient between the transverse sinuses and the area of the wearer's head adjacent each secondary cooling portion of the plurality of secondary cooling portions when the headwear is worn on the wearer's head; and
a plurality of tertiary cooling portions that each extend from a secondary cooling portion of the plurality of secondary cooling portions and are configured such that when the headwear is worn on a wearer's head they overlie the sigmoid sinuses wherein the tertiary cooling portions each have a width of between 50 and 60 mm and set up a temperature gradient between the sigmoid sinuses and an area of the wearer's head adjacent each tertiary cooling portion of the plurality of tertiary cooling portions when the headwear is worn on the wearer's head; and
gaps that do not provide a cooling effect located between the first cooling portion and the plurality of secondary cooling portions and between each of the secondary cooling portions of the plurality of secondary cooling portions.
