Before Flamengo took the field against Mirassol on Wednesday (02) at the Maracanã, Arrascaeta caught the fans’ attention because of a curious detail. The Uruguayan arrived at the stadium wearing special glasses that projected a green light onto his eyes.
The accessory quickly sparked the curiosity of Flamengo’s supporters. After all, what was the purpose of the technology used by the Flamengo midfielder? The equipment belongs to AVA and was developed by engineer Rodrigo Santana.
The device is called Circádia, and one of its main functions is to help regulate the circadian rhythm through the eye region. In this way, the technology aims to influence the body’s natural sleep-wake cycle.
In addition, the glasses emit a green light directly onto the retina. This area contains a substance called melanopsin, which reacts to light stimulation and can increase the production of cortisol, a hormone associated with alertness.
Because of this, the technology can help athletes who need to maintain their level of attention during periods when the body would normally be prepared to rest. In football, this need appears mainly in matches played at night.
Naturally, the human body tends to stay more alert in the morning and seek rest at night. However, a football player’s routine requires adjustments, since matches, training sessions, and professional commitments also take place at night.
In this scenario, the technology seeks to adjust the circadian system to keep the athlete awake and alert. Thus, Arrascaeta can use the equipment as part of a strategy to adapt his body to the demands of a sporting routine. Circádia, however, does not require long periods of use. The device only needs to be worn for a few minutes and costs approximately R$ 1,200.
While Arrascaeta drew attention before the match, Flamengo did their job on the pitch. The Rubro-Negro beat Mirassol 2-0 at the Maracanã in a postponed match from the fourth round of the Brazilian Championship.
With the result, Flamengo moved even closer to leaders Palmeiras. The Rubro-Negro are now just one point behind first place, reaching their smallest gap to the top since the start of the competition.
