With the arrival of fall, the days grow shorter, natural light diminishes, and many people feel that their bodies crave more rest. The change of season and sleep are linked primarily by the way light helps regulate our biological clock.

Feeling more sleepy at this time of year does not, in and of itself, mean there is a problem. The change of seasons alters the amount and timing of the light we are exposed to and can influence when we feel sleepy, our energy levels during the day, and how easily we maintain our usual routine. The effect, however, is not the same for everyone.

How does our sleep change when fall arrives?

The most noticeable change is the light. As fall progresses, dawn comes later and dusk falls earlier. This reduction in the photoperiod alters the environmental cues that help the body distinguish between day and night.

Research on seasonal sleep patterns shows that exposure to light during the day is associated with sleep timing and the circadian rhythm. Studies conducted across different seasons have observed changes in bedtime and wake-up time and reinforce the idea that the actual amount of light received throughout the day may be more relevant than the season alone in explaining these changes.

If you'd like to learn more specifically about the role of lighting, Leafsleep also explains how light affects sleep and the importance of creating an environment that's more conducive to rest at the end of the day.

The time change can also disrupt your routine

In the fall, the switch to standard time adds another change to the rhythm of the day. Even though it’s just one hour on the clock, the change occurs at the same time that the days are already getting shorter, which can make the feeling that it gets dark too early seem even more pronounced.

For some people, the adjustment is almost imperceptible; for others, it may take a few days. Maintaining relatively regular schedules for waking up, eating, working, and going to bed helps give the body a sense of consistency during this transition.

The bedroom should also reflect the changing seasons

Adjusting to fall isn’t just about changing our schedules. The environment where we sleep also changes: the nights get cooler, we use more bedding, and we start keeping the windows closed for longer periods of time. The goal should be to create comfort without making the bed too hot or stuffy.

Breathable materials help maintain a sense of balance throughout the night. The Nature Cloud Cotton Mattress combines natural cotton, TENCEL™ Lyocell, and a BioCell® core in a design engineered for comfort, coolness, and breathability in every season.

As the nights get cooler, you can also gradually adjust your bedding. The Percale Duvet is ideal for fall and winter and combines combed percale cotton with a 350 g/m³ fill, providing extra warmth without sacrificing breathability.

Creating a fall ritual can help your body recognize when it's time to rest

Fall naturally invites us to slow down. Instead of viewing this change simply as a lack of energy, you can use it to establish a more consistent sleep routine: dim the lights at the end of the day, prepare your bedroom, put your cell phone away, read for a few minutes, and stick to a consistent bedtime.

A consistent routine is especially helpful when the outside environment is changing. Small cues repeated night after night help distinguish between wakeful and restful times and make the transition to sleep more predictable.

At Leafsleep, sleeping naturally also means respecting these rhythms without sacrificing a balanced routine. Making the most of daylight, maintaining consistent schedules, and creating a comfortable sleeping environment are small choices that help you get through the fall with greater balance—night after night.
