Sleep Expert Debunks Myths as Clocks Spring Forward Today

The clocks moved forward from 2:00 AM to 3:00 AM last night, on March 29th, 2026, as daylight saving time began. This annual shift is a familiar event across Sweden and many other countries, marking the start of longer evenings. Swedish sleep researcher John Axelsson from the Karolinska Institute has commented on common claims about the time change's impact in recent interviews. He spoke directly to the Swedish news agency TT, which stands for Tidningarnas Telegrambyrå, about one widespread belief. "It's a myth that we lose an hour of sleep every day for the rest of the year," Axelsson told TT. According to his expert analysis, the human body typically recovers from the initial adjustment within just a couple of days. The researcher explained that the perception of ongoing sleep loss is not accurate. The body's internal clock, or circadian rhythm, adapts relatively quickly to the new time schedule. This adjustment process involves exposure to light and daily routines. Axelsson's comments were made in the context of the specific time change that occurred on March 29th. His input addresses concerns that arise each year when summer time is introduced. The transition can cause temporary sleep disruption for some individuals, but the researcher emphasizes that this is a short-term effect. The claim of a permanent, daily one-hour sleep deficit is incorrect based on current sleep science. This perspective from a leading Swedish researcher offers a clear, science-based counterpoint to popular concerns. It provides reassurance for many people in Stockholm and beyond who feel the effects of the time change each spring. The information is relevant as people search for guidance following the clock change. The discussion focuses on the immediate period after the shift from a prominent medical university in Sweden.
