Springing forward for daylight saving time will be especially hard this year due to sleep loss from COVID-19. Why does the US keep doing this?
Time changes interrupt our internal “body clock”.

Time changes make many people feel tired, irritable, and unable to sleep.
Our circadian rhythm is an important aspect of our health.

Researchers are only beginning to understand the relationship eating time and circadian rhythm have on our body weight.
Spending more time in bed and letting your body’s natural rhythms take over could be good for your health.
The time at home from the coronavirus crisis could be an opportunity to let our natural sleep rhythms take over.
Many baby books promote sleep-training methods that involve leaving babies to cry at night. But there are gentler ways to get a good night's sleep.
It’s harder for kids to get to sleep when it’s light outside and they’re not as tired.
Daylight saving time starts this weekend, and it can often be the beginning of new dramas getting kids to bed. Here's how to make the transition a little smoother.
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.
Could too much light in the evening affect children’s sleep? Recent research suggests that it could.
A recent study suggested that a chemical responsible for getting the body ready for sleep was suppressed in children by too much evening light. A circadian rhythm expert explains the dangers.
Night owls, or people who have a hard time waking up in the morning, face health risks as a result.
Pity the poor night owls of the world, who already must adjust to a life that doesn't align with their natural sleep patterns. Now it appears that being a night owl even raises the risk of death.

Most Americans dread the time switch to daylight saving time, which results in a loss of an hour's sleep. The downside is more serious than that – it can lead to workplace injuries and traffic fatalities.
