During a study conducted at Leuven University, Belgium, 2,500 youngsters, aged 13 to 16, were asked how often they were awakened by incoming text messages on their cellular phones and how tired they felt at various times.
Lēvenes universitātes (Beļģija) pārstāvji aptaujāja 2,5 tūkstošus jauniešu vecumā no 13 līdz 16 gadiem, lai noskaidrotu, cik bieži viņu miegu traucē atsūtītās īsziņas un cik ļoti viņi jūtas noguruši.
