Longer, brighter evenings sound tempting. But year-round daylight saving time could have significant consequences for our natural sleep-wake cycle. A new U.S. study shows how many children would have to be out and about in the dark in the mornings as a result. Behind this lies a fundamental question of chronobiology: How much does our […]
A large, long-term study involving more than 87,000 adults provides surprising insights into the link between daylight and brain health. People who were exposed to more bright light during the day were less likely to develop dementia during the observation period. Particularly striking: even less than 42 minutes of bright daylight per day was associated […]
Our internal clock controls far more than just our sleep. It influences numerous biological processes that change throughout the day. A new study from October 2026 shows that the daily rhythms of light exposure and wrist temperature are also linked to markers of metabolic health. A particularly intriguing question is whether wearable sensors will help […]
They hunt skillfully, respond to their surroundings, and appear to enter a state at night that bears striking similarities to our sleep. Researchers have observed two distinct sleep phases in an Australian jumping spider—including a phase with rapid eye movements and muscle twitches reminiscent of human REM sleep. Whether the animals actually dream remains an […]
