Why harmfully to roll in bed late?
healthy lifestyle and healthy dream - melatonin.
Researchers assert that teenagers whom the big efforts that in the morning to rise from bed are required, receive insufficient quantity of sunlight. It leads to infringement of job of their internal clocks and, as consequence, to insufficient development in the evening dream hormone melatonin.
Why harmfully to roll in bed late? The American scientists have come to a conclusion that modern teenagers spend too much time in the closed premises. It leads to that shortage of sunlight, especially in the mornings, breaks job of their internal clocks: at night they feel less sleepy, and, as consequence, late go to bed, and next day feel strongly got tired. Researchers have entitled phenomenon «teenage syndrome of the night-bird» and have underlined that in examinations this infringement of dream can become the reason of bad estimations.
«As teenagers spend too much time indoors, they don't receive enough of morning sunlight which is necessary for job of biological control system by dream and wakefulness mode, – Mariana Figueiro from the Research centre of illumination at Polytechnical institute Rensselira, the USA speaks. – the teenagers deprived of sunlight, go to bed later and sleep it is less. It can lead to unsatisfactory results in passing examinations».
Doctor Figuejro and its colleagues assert that influence of morning light extremely important for job of internal clocks of the teenager. Influence of specific short-wave radiation to which there corresponds dark blue colour, promotes that along toward evening at the person hormone development melatonin which signals becomes more active that there comes dream time. If sunlight the person receives insufficiently by the evening it will be difficult to it to fall asleep.
To check up correctness of the theory, scientific have made experiment. They have selected eleven 14 years old teenagers and to each of them have given out special points which didn't pass dark blue colour that examinees carried them during the day. In five days it has appeared that teenagers began to go to bed on the average on half an hour later, than earlier. Scientists have come to a conclusion that the reason of frustration of dream at young men is covered often that they receive insufficient quantity of sunlight on the way to school. They consider that entering into projects of school cases of such changes which would promote the best penetration into sunlight premises would be the most simple way out.
