Sleep Science — April 28, 2026
Sleep researchers and professional organizations are preparing to celebrate outstanding contributions to the field at the upcoming SLEEP 2026 annual meeting, with both the Sleep Research Society and the American Academy of Sleep Medicine (AASM) announcing their 2026 award recipients. Meanwhile, NASA-linked circadian science is offering jet-lagged travelers a more precise framework for using light exposure to reset their internal clocks — and new research confirms that timing, not just exposure, is everything.
Sleep Science — April 28, 2026
Key Highlights
Sleep Research Society and AASM Honor 2026 Award Recipients
Both of the field's major professional organizations announced their 2026 honorees this week. The Sleep Research Society will recognize four sleep and circadian scientists at SLEEP 2026 for contributions to research, education, and public service.
Separately, the AASM will honor five individuals at the same SLEEP 2026 annual meeting for contributions spanning research, education, advocacy, and clinical care.
NASA-Linked Circadian Science Reshapes Jet Lag Advice
The conventional wisdom of "get outside and get some sunlight" to fight jet lag is incomplete — and potentially counterproductive if timed wrong. New reporting drawing on NASA-linked circadian research explains that light exposure only works when aligned with the traveler's internal biological clock phase. The direction of travel, the number of time zones crossed, and whether you are phase-advancing or phase-delaying all determine the optimal window for light exposure. Used at the wrong time, bright light can actually make jet lag worse.
Senior Sleep Struggles: Dreams, Distress, and Nocturia
A recent lifestyle piece highlights a trio of specific challenges faced by older adults seeking restorative sleep: vivid or distressing dreams, and nocturia (waking repeatedly to urinate at night). For many seniors, these issues compound each other in a cycle that fragments sleep architecture and reduces overall sleep quality. The piece offers evidence-based tips for deeper rest tailored to this demographic.
Analysis
Timing Is the Secret Ingredient in Light-Based Jet Lag Therapy
The Forbes piece published April 27, 2026, building on NASA-affiliated circadian research, distills an important concept: light is a powerful zeitgeber (time-giver), but its effect is phase-dependent. The human circadian clock does not respond uniformly to bright light — it responds differently depending on where you are in your ~24-hour biological cycle.
Here's why this matters practically:
- Flying eastward (advancing your clock) generally requires morning light at the destination.
- Flying westward (delaying your clock) generally benefits from evening light.
- Using bright light at the wrong circadian phase can shift the clock in the wrong direction, prolonging jet lag rather than curing it.
NASA's interest in this research is obvious: astronauts returning from missions with radically disrupted schedules need precise protocols to re-entrain their circadian rhythms quickly and safely. The same principles, when translated to travelers, offer a far more targeted approach than blanket recommendations to "get sunlight."
The takeaway for frequent flyers: before your next long-haul flight, consider mapping your departure and arrival times against your current circadian phase, and use light — or darkness — strategically rather than instinctively.
Sleep Hack
Use a "Light Schedule," Not Just Light Exposure, for Jet Lag
The science is clear: getting sunlight after an eastward flight helps — but only if you get it at the right time relative to your internal clock. Before traveling across multiple time zones, note your habitual wake time at home and use it as an anchor. On arrival, seek bright outdoor light in the morning (for eastward travel) or avoid it in favor of evening light (for westward travel). Apps based on circadian modeling, such as those developed from NASA research, can calculate your personal optimal light-seeking windows by time zone shift and direction of travel. This precision approach has shown measurable advantages over generic "get outside" advice in reducing jet lag duration.
