Circadian Rhythms

Are you on any kind of daily medication? Do you take those drugs in the morning or the evening? According to an emerging body of research, the time of day you take a medication may influence how well it works, or how much it harms.

Where most of Polar's smartwatches are aimed at outdoor enthusiasts, the Ignite 3 is heading to the wrists of a more casual fitness crowd, and can tap into an individual's circadian rhythm to predict when wearers will be most alert and ready to focus.

People subjected to irregular sleeping and eating habits through shift work are known to have higher risk of a wide range of health problems, and a new study has drilled into the impacts of this lifestyle on mental health.

A new study on fruit flies may help explain why siestas came to be such an important habit in many cultures, revealing a type of brain thermometer that kicks sleep-promoting cells into action as the mercury starts to climb.

Scientists have designed a smart mattress designed to tap into the body's circadian rhythms, carefully heating and cooling different areas to coax you into a deep slumber, with some promising results from an early trial.

A new study has drilled into the relationship between the timing of our meals and the body's blood glucose levels, finding that those chowing down after dark may be at greater risk of diabetes and obesity.

Newly published research has delved into the relationship between bedtimes and the risk of developing cardiovascular disease, and has found that hitting the hay between 10 and 11 pm could provide benefits to the heart.

New research has discovered a distinct circadian mechanism within heart cells that influences how cardiac activity shifts across 24-hour periods. The findings offer clues to why shift workers are at higher risk of heart problems.

Most asthma sufferers will know their symptoms are often worse at night. But why is this the case? A fascinating study has put more than a dozen asthma patients through two rigorous experiments and found the body’s circadian clock may be responsible.

Studies are starting to demonstrate how one day we might be able to check the time of our body clock through a simple blood test, and a team at the University of Colorado Boulder has now put forward a promising new technique called "metabolomics."

A new study testing smartphone night modes that eliminate blue light wavelengths is suggesting they make no difference to overall sleep outcomes and the only way to improve sleep at all is to completely abstain from screen use before going to bed.

Research has found night shift work can alter the expression of tumor-related genes making one more vulnerable to the DNA damage the leads to cancer, building on a growing understanding of the role circadian rhythms play in our DNA repair processes.
