During the dark winter months, Swedes long for the endless, bright summer evenings, a Midsummer Night’s Dream, if you like. But those long daylight hours, can be a nightmare for some Swedes, who have trouble sleeping.
Just before Midsummer, a study has been launched at the Sleep Laboratory at Stockholm University, to see how our sleep is affected by the bright summer nights. Fifteen subjects will be tested first while they have been living as normal, then after camping out during the short nights of high summer.
The researchers want to see how our biological clocks are affected by the minimal darkness of the Swedish summer.
“We want to find out how we adapt biologically to live so far North,” says John Axelsson, a professor of Sleep Science. “From an evolutionary perspective, we’ve lived up here in the North a very short period, and perhaps there are negative consequences of such differing amounts of light.”
