Our bodies run on internal clocks called circadian rhythms, which tell us when to wake up and when to sleep. These clocks are heavily influenced by light—especially the kind we’re exposed to during the day versus at night. New research suggests that when and how much light we get might play a bigger
Research suggests that when adults exercise might matter as much as how much they move. A recent study tracked nearly 800 people using wrist devices for a week, measuring not just their activity levels but also when they were most active. Those who hit their peak movement earlier in the day had stro
A big five-year study followed over 7, 000 adults aged 40 to 65 and found that eating breakfast early helps keep weight down. Skipping breakfast or eating late in the afternoon, however, did not help with weight loss and was often linked to worse habits like smoking and drinking alcohol. The key tak
Traveling long distances can leave people feeling wiped out, even after they’ve tried every trick known to humanity. A recent gathering of experts—an ex‑astronaut, a airline leader, a champion athlete, an app creator and a sleep scientist—offered fresh insights based on the science of our internal c
The body’s internal clock can change how we react to food. A new study shows that eating fried oil at the wrong time of day can damage kidneys. Mice that ate oxidised frying oil whenever they wanted had trouble turning certain harmful molecules, called epoxides, into safer ones, called diols. Thi
It can be hard to slip into sleep if your brain stays on alert. A simple nightly routine can tell the body it’s time to shut down and calm itself. One trick is to lower the light level in your home before bed. Turning off bright overhead lights and using a soft lamp helps the body release melaton
Flies, like many creatures, have internal clocks that help them stay on schedule. These clocks control when they sleep, eat, and do other important things. But not all flies stick to the clock perfectly. Some are more flexible, and this flexibility might help them survive when things get tough. One
In a groundbreaking discovery, a group of researchers in Japan have identified a compound that could revolutionize how we deal with jet lag and other sleep disorders. This compound, named Mic-628, has shown promising results in resetting the body's internal clock, known as the circadian rhythm. The
People who stay up late might be putting their hearts at risk. A recent study shows that night owls, especially those in middle age and older, have worse heart health. This is likely because they make choices that aren't good for their hearts, like eating poorly, smoking, and not getting enough slee
People who go to bed around 9 p. m. tend to be more active during the day. A study with 20, 000 participants showed that these early sleepers move more than those who stay up late. This is because their sleep aligns with their body's natural rhythm, giving them more energy. When people ignore their
