Olympic swimmers were stimulated by Ultra-High Blue Light
Jeanette Ottesen, the OL bronze medalist who was one of the swimmers from Denmark made use of blue light in improving the speed of her reaction in the last Rio Olympics.
As Olympic swimmer, it is a very hard task to be at your best when your circadian rhythm (also known as biological clock) is knocked off kilter. Brazil – the country which is dive hours behind of Denmark – was the venue of the Olympic Games which was completed recently. Both semi finals and finals were held between 10.pm and midnight.
The swimmers who participated in these games were faced by two great challenges. Relatively, the time difference was not hard to deal with. The swimmers were only needed to travel to the Venue, Rio, in advance of the competition and maintain their normal training, mealtime and bed time patterns.
The second challenge was to be awake and be informing for the competitions which were being held in late hours.
In order for the swimmers to improve their reaction time and making sure that they hard peaceful night, a special light concept was developed for Team Denmark by DTU who worked hand in hand with the team.
This light illuminated rooms with blue light which was varying in the level of blue light in the day time in order to support the Team Denmark members with their circadian rhythms was installed in the rooms occupied by the swimmers and other shared areas.
Light in Plenty
According to Jakob Hildebrand, Andesen, who is the Researcher Assistant at DTU Fotonic, he said that the body normally gears down in the fall of darkness. And for that reason, they had to compensate for the lack of daylight by providing plenty light in the rooms. The bulbs with an ultra high blue light were lighten up in ensuring that the swimmers were at their best in the times when they are needed to compete.
