Jim Horne, director of the Sleep Research Centre of Loughborough University in England, said in an interview that this difference can be attributed to the fact that women are likely to multitask more frequently throughout the day, causing them to use more of their brain power than men. Thus by the end of the day women are more tired than men and will fall asleep earlier.

The study revealed that bedtimes become earlier as age increases : 20—24 year olds go to sleep on average at a. The average wake-up time moves in the same direction, except that it increases again once people reach the age of One possible explanation for this is the effects of retirement and the end of needing to adhere to strict sleep schedules.

Sleep requirements vary by age, and they will affect when a person should go to sleep and wake up. The following table shows how many hours of sleep a person needs each day, according to their age :. The sleep cycle is a natural internal system in humans.
It is a combination of external conditions, such as light, personal behaviors, and lifestyle choices, and internal conditions, such as brain wave patterns and genetics. The body moves between these states a few times a night. The body cycles through these stages roughly every 90 minutes. Ideally, the body will pass through four to five of these cycles each night.
Waking up at the end of the cycle, when sleep is lightest, may be best to help the person wake feeling more rested and ready to start the day.
An alarm going off when a person is in one of the deeper stages of sleep may lead to grogginess or difficulty waking up. Again, these stages vary from person to person, meaning that no single timing for sleep is right for everyone.
Paying attention to how they feel in the morning and noting how many hours of sleep they got may help a person identify their sleep cycle and determine how much sleep they need.
Anyone struggling to fall or stay asleep throughout the night may wish to see a doctor for a diagnosis. An underlying issue may be causing the insomnia. In other cases, a person may get enough sleep but still wake up each morning feeling unrested. This symptom could indicate other health issues, such as obstructive sleep apnea.

A new study from researchers at the University of Michigan published in the journal Science Advances has captured the "normal" sleeping habits of people around the world, using data from a smartphone app. Of the 20 countries with the highest number of respondents, people in the Netherlands on average reported sleeping nearly an hour more than those reporting from Singapore and Japan. Americans were among the earliest morning risers alongside Australians, while those in Australia tended to go to bed earlier.
How late people went to sleep showed to be a stronger indicator of how much time people slept overall rather than what time they woke up: The later people go to bed, the less sleep they get on average. Now the researchers are determined to figure out why this is, Daniel Forger, the study's co-author, said. It's still unclear if the differences in sleep times have a stronger correlation with culture influences, like what activities or societal pressures lead people to sleep later or wake up earlier, or with differences in light exposure.
But it is clear that sunrise and sunset affect when people wake up. According to the study, later sunsets seemed to correlate with longer sleep durations. The data was self-reported through Entrain, a smartphone app originally developed to help with jet lag, which allows people to self-report their sleeping habits as well as tracks outside light patterns.
