Every spring, millions of people notice the same thing: sleep gets worse. They wake earlier than they want to, lie awake longer at night, feel groggy despite spending enough hours in bed, or find their carefully maintained sleep schedule suddenly unreliable. Conventional wisdom blames daylight saving time, and that's part of it—but only part. Spring disrupts sleep through several distinct mechanisms that stack on top of each other, and understanding them explains why the problem often lingers for weeks past the initial time change.
Multiple Sleep Disruptors Working Simultaneously
The spring clock change delivers measurable disruption—researchers have documented increases in car accidents, heart attacks, and workplace injuries in the days following. Full circadian adjustment takes 5-10 days for most people. But the time change is just the beginning of spring's assault on sleep quality.
Four ongoing factors continue disrupting sleep through April:

Best regards, The Security TeamEarlier sunrises suppress melatonin: In early March, sunrise occurs around 6:30 a.m. By late March, before 6:00 a.m. By late April, before 5:30 a.m. Light entering bedrooms earlier suppresses melatonin production sooner, making sleep shallower and more fragile. People without blackout curtains wake 30-60 minutes earlier than intended
- Temperature swings through the night: Spring evenings at 60°F drop into the 40s by 3 a.m., then climb back to 55°F by dawn. These fluctuations pull you out of deep sleep stages without fully waking you, leaving you tired in the morning without knowing why
- Later sunsets delay sleep onset: The sun sets later—from 5:30 p.m. in early March to past 7:30 p.m. by late April. Longer natural light delays melatonin release, pushing sleep onset later. Combined with fixed wake times, this reduces total sleep duration by 30-45 minutes nightly
- Accumulated sleep debt: A consistent nightly deficit of 30-45 minutes accumulates into hours of lost sleep within a month, affecting mood, cognition, metabolism, and immune function
Strategies That Actually Work
Blackout curtains are the single most effective intervention—even inexpensive ones extend morning sleep by 30-60 minutes by blocking light that suppresses melatonin. Shift bedtime gradually (15 minutes earlier every few days) rather than trying to enforce an abrupt change. Manage bedroom temperature actively with consistent thermostat settings rather than turning off heat entirely on mild days. Get bright light exposure within an hour of waking to accelerate circadian adjustment. Limit evening screen light after 8 p.m. when sun is already setting later and delaying melatonin production.
By May, most people find sleep has settled as the body adapts. The weeks from late March through April are most disruptive—knowing what's driving restlessness makes it easier to address rather than simply endure.
