How Daylight Saving Time Changes Affect You and What You Can Do About It

The shift can disrupt sleep, and health groups say 1 in 3 U.S. adults and more than half of teens already sleep too little.

  • Spain set clocks back one hour on Sunday, October 25, 2026, beginning winter time. Mainland and Balearic clocks moved from 3 a.m. to 2 a.m., while the Canary Islands shifted from 2 a.m. to 1 a.m., granting residents an extra hour of sleep.
  • This adjustment follows a five-year schedule approved by Spain's Official State Gazette in 2022 under Royal Decree PCM/186/2022, which mandates annual time changes through 2026 to enable advance notice for citizens and organizations.
  • Medical biochemist Jane Ollis warns that reduced morning light during this transition can disrupt circadian rhythms, potentially causing sluggishness. Experts suggest consistent morning light exposure and exercise to regulate cortisol and serotonin while adjusting to shorter days.
  • Spain adopted its current time zone in 1940 under General Francisco Franco, a legacy critics argue "no longer makes sense." Campaigners push for a return to Greenwich Mean Time, complicating ongoing debate over abolishing the twice-yearly shifts.
  • While the current five-year calendar concludes with this 2026 change, the long-term future remains uncertain as the European Union has yet to reach a definitive agreement on abolishing seasonal time changes beyond this year.
