Why do some people need more sleep than others? It's a question many of us have asked, whether we're the ones who need a full eight hours or more, or the ones who can function on just a few hours a night. According to sleep experts, the answer may lie in our genes. A recent study by the American Academy of Sleep Medicine has shown that some people are genetically predisposed to needing more sleep, while others are short sleepers, needing just four and a half hours or less. But it's not just our DNA that determines our sleep needs – factors like age, gender, and lifestyle can also play a role. For example, women may need more sleep due to menstruation, menopause, or pregnancy, while older adults tend to need less sleep than younger adults.

Genes: some people are genetically predisposed to needing more sleep
Genes play a significant role in determining how much sleep we need. According to sleep experts, some people are genetically predisposed to needing more sleep. A study by the American Academy of Sleep Medicine found evidence that some people require more sleep from the start. This is supported by another study that found personal sleep requirements may be linked to our genes.
Some people can function well on just a few hours of sleep, while others need 10 hours or more to stay alert. These differences are well-documented, but the reasons behind them have only recently been explored. For example, researchers at the University of California, San Francisco, found that 'short sleepers' who need less sleep tend to have a mutation in seven genes that regulate sleep.
Other factors that can affect sleep include age, gender, and lifestyle. The American Sleep Foundation reports that menstruation, menopause, and pregnancy can interrupt sleep, leading to longer sleep durations. Additionally, unpaid housework and a lack of opportunities for daytime naps can also impact sleep.
To improve sleep quality, it is recommended to establish a regular daily routine, including consistent wake-up and bedtime, regular exercise, and set meal times.

Age: older and younger people tend to need more sleep
Age is a key factor in determining how much sleep a person needs. Older and younger people tend to need more sleep than those in the 18-64 age range, whose sleep needs often fall on the lower end of the scale. This is because the body is trying to fight off an infection or develop a chronic medical condition.
Younger people, especially babies and toddlers, need more sleep than adults. This is because their bodies and brains are growing and developing rapidly, and sleep plays a crucial role in this process. During sleep, the body produces growth hormones that are essential for physical growth and development. Additionally, sleep helps the brain to process and consolidate new information, which is particularly important for young children who are constantly learning and acquiring new skills.
As people age, their sleep patterns and needs can change. Older adults may find that they need more sleep than they did when they were younger. This could be due to a variety of factors, including changes in sleep architecture, the presence of health conditions, and the use of certain medications. Older adults may also experience more sleep disruptions due to factors such as pain or discomfort, frequent urination, or changes in their sleep environment.
Additionally, older adults may be more likely to experience sleep disorders such as insomnia or sleep apnea, which can further contribute to their increased sleep needs. It's important for older adults to prioritize sleep and seek help if they are experiencing sleep difficulties. Maintaining healthy sleep habits can help improve overall well-being and quality of life as people age.
Overall, age plays a significant role in determining how much sleep a person needs. While younger and older people tend to require more sleep, it's important to remember that individual sleep needs can vary. Establishing a consistent sleep schedule, maintaining a healthy lifestyle, and seeking professional advice for sleep difficulties can help ensure that people of all ages get the rest they need.

Gender: women tend to need more sleep due to menstruation, menopause, and pregnancy
There are many reasons why some people need more sleep than others. For most people, needing more than the average of eight hours of sleep per night could indicate that the body is fighting off an infection or that there is a chronic medical condition developing. However, some people are just genetically predisposed to needing more sleep. Research has shown that there are people who need more sleep from the start of their lives. These people are known as 'short sleepers' and have been found to have a mutation in seven genes that play a role in regulating sleep.
Gender also plays a role in how much sleep people need. Women tend to need more sleep due to menstruation, menopause, and pregnancy, all of which can interrupt sleep and lead to women staying in bed longer to make up for periodic awakenings. Additionally, women still perform more unpaid housework than men, which can result in fewer opportunities for catch-up naps during the day.

Health: people who are unwell or have a chronic medical condition may need more sleep
People who are unwell or have a chronic medical condition may need more sleep. For most people, sleeping more than the average of eight hours per night is a sign that the body is fighting off an infection or that there could be an underlying chronic medical condition.
Sleep requirements vary from person to person, and this can be attributed to genetic factors. Certain people are genetically predisposed to needing more sleep. Researchers have found that some people, known as short sleepers, have a mutation in seven genes that regulate sleep. These individuals can function with four and a half hours of sleep or less and tend to have higher energy levels, optimism, and pain tolerance.
Factors such as age, gender, and life circumstances also influence sleep needs. The youngest and oldest individuals typically require the most and least sleep, respectively. Women may experience interrupted sleep due to menstruation, menopause, or pregnancy, leading to a need for more sleep to compensate for periodic awakenings. Additionally, responsibilities like unpaid housework and limited opportunities for daytime naps can impact sleep duration.
To optimise sleep, it is recommended to establish a consistent daily routine. This includes maintaining a regular sleep and wake schedule, exercising at optimal times, having meals at set hours, and avoiding late dinners. Powering down electronic devices an hour or two before bedtime can also aid in achieving better sleep.

Lifestyle: a regular daily routine can help you get better quality sleep
While some people need more sleep than others due to genetics, there are other factors that can influence the amount of sleep we need. For example, if you're fighting off an infection or developing a chronic medical condition, you might need more sleep.
Having a regular daily routine can help you get better quality sleep. This is because it helps to recalibrate your internal clock. You can do this by setting a fixed time to wake up and go to bed every day. It's also important to exercise during the morning or early evening peaks and have your meals at set hours. Try not to eat dinner too close to bedtime, and power down your phone or tablet an hour or two before you go to sleep.
If you're struggling to get enough sleep, it might be helpful to know that researchers have found that people who need less sleep tend to score higher on tests of energy, optimism, and pain tolerance. These people are known as 'short sleepers' and have a mutation in seven genes that play a role in regulating sleep.
However, it's important to note that needing more sleep than the average of eight hours per night could be a sign that your body is fighting off an infection or that you have a chronic medical condition. In these cases, it's best to consult a doctor.
