The heat in Greensboro, North Carolina, where Norway has its World Cup base, is intense and the players' well-being is being monitored with urine tests.
"It's the World Cup in urine testing, so it quickly reveals if someone has been in the sun too much. We have medical staff who keep an eye on them. The players pee before and after training and when they wake up," says Solbakken.
"I haven't been notified of anything crazy yet," he adds.
Norway traveled to the United States after the 3-1 victory over Sweden on Monday and will face Morocco in a friendly match on Sunday.
Stars Erling Braut Haaland and Martin Ødegaard did not play against Sweden, but, according to Solbakken, they will get a lot of playing time against Morocco.
Norway will face Iraq in their first World Cup match on June 17.
