Is a bottle of morning milk at night the equivalent of turning on all the lights at bedtime?
Breast milk contains ingredients in concentrations that change over the course of the day. Researchers think milk is chrononutrition, carrying molecular messages to help set a baby's internal clock.
Researchers find 351 genetic variants associated with a person's chronotype. Before this study, we knew of only 24.
Our study found that the performance of “night owls” and “morning larks” varied considerably on both cognitive and physical tasks.
The old saying 'the early bird catches the worm' might be especially fitting when it comes to peak mental and physical performance.
Changing to daylight saving time can impact our mood, our risk of heart attack and how much exercise we get.
Daylight saving time begins this weekend, which means many of us will get an hour less sleep. But the health effects go beyond sleep – and can last two weeks or more. Here's what the research says.
The circadian rhythm is present in every single cell of your body, guided by the central clock that resides in the brain.
Everybody has a personal internal clock in their brain that dictates when we feel like eating, waking and sleeping. But what happens when our life doesn't match our body clock? And how do we read it?
When you eat is as important as what you eat. The mounting evidence for chrononutrition.
Getting enough sleep can help our memory, waistline and our performance at work.
If you need an alarm to get up in the morning, you're probably not getting enough sleep.
Biological clocks set the pace for nearly all living things, and Jeffrey Hall, Michael Rosbash and Michael Young – awarded the Nobel Prize in Physiology or Medicine – helped us understand how.
‘The key fourth awardee here is … the little fly,’ Hall said.
Americans Jeffrey Hall, Michael Rosbash and Michael Young share the 2017 Nobel Prize in Physiology or Medicine for work that explained how our cells keep track of time.

All parents have probably struggled to get their kids to sleep at some point. This is even more difficult when a child has ADHD.
Children with ADHD are much more likely than other kids to struggle getting to sleep, and staying asleep. Up to 73% of Australian parents report their child with ADHD has problems sleeping.
Next time just work with your body clock.

We aren't slaves to our body clocks: changing your routine could make a huge difference to your sleep patterns.
Light from electronic devices can alter the quality of sleep our quality.
While many of these devices, especially e-readers, seem harmless enough, the light they emit may affect our sleep patterns and leave us feeling tired the next day.
Time spent checking the clock when you can’t sleep may be feeding your insomnia.
We all have a poor night’s sleep from time to time: those nights when you lie awake for hours trying desperately to go to sleep but can’t stop worrying about tomorrow. Or when you repeatedly wake up throughout…
