What You'll Learn
Genetics and age
The amount of sleep a person needs is influenced by two factors: genetics and age. An individual's preference for rising early or sleeping late is largely influenced by genetics. These are the so-called "larks" (morning-type individuals) or "owls" (evening-type people).
Genetics plays a role in determining the amount of sleep a person needs. For most adults, the ideal number is between seven and nine hours. However, this may vary depending on other factors such as personality traits and medical conditions. For example, a 2018 study found that extroverts and those with a lower tendency to experience distress and negative emotions had better overall sleep quality, while introverts and those with difficulty managing self-discipline or organisation faced more sleep challenges.
Age also influences the amount of sleep a person needs. Sleep guidelines can offer a starting point for determining sleep needs at different ages, providing research-backed recommendations for optimal health. As people age, their sleep patterns and needs may change, and it's important to adjust sleep schedules accordingly.
To determine the exact amount of sleep needed, it's recommended to take a "sleep vacation". During a two-week period of a flexible schedule, pick a consistent bedtime and wake up naturally without an alarm clock. Initially, you may sleep longer to pay off your "sleep debt," but eventually, you'll establish a natural sleep pattern, likely falling within the range of seven to nine hours.

Sleep debt
The amount of sleep you need is influenced by genetics and age. If you are an early riser or a "lark", you are likely to have a genetic predisposition to needing less sleep. On the other hand, if you are an "owl" or an evening-type person, you may need more sleep. Your personality may also hold clues to your sleep habits. According to researchers, extroverts and those with a lower tendency to experience distress and negative emotions tend to have better overall sleep quality. Introverts and those who have difficulty managing self-discipline or organisation tend to have more sleep challenges.
To determine the exact amount of sleep you need, it is important to consider your individual needs and preferences. You can try different ways to figure out how much sleep you need beyond health expert recommendations. Consulting a healthcare professional or a sleep specialist can also help you determine how much sleep you need, especially if you have any other medical conditions.

Sleep cycles
Sleep is a highly individual experience, and the amount of sleep you need may vary depending on your genetics, age, and personality. For most adults, the ideal amount of sleep is between seven and nine hours. However, some people may need more or less sleep to function optimally.
To determine the exact amount of sleep you need, you can try a "sleep vacation." During a two-week period when you have a flexible schedule, pick a consistent bedtime and allow your body to wake up naturally without an alarm clock. Initially, you may sleep longer to pay off your "sleep debt." But over time, you will establish a natural sleep pattern, indicating the amount of sleep your body needs.
Another way to determine your sleep needs is to consult a healthcare professional or a sleep specialist. They can provide personalised advice and help you improve your sleep quality, especially if you have any medical conditions.
Additionally, understanding your natural sleep cycles is crucial for optimising your sleep. Sleep cycles refer to the different stages of sleep that your body cycles through during a typical night's rest. These stages include light sleep, deep sleep, and REM (rapid-eye movement) sleep, which is associated with dreaming. By aligning your sleep schedule with these natural cycles, you can wake up feeling more refreshed and energised.
To calculate the best time to go to bed based on your wake-up time and sleep cycles, you can use a sleep calculator or a sleep tracking app. These tools can help you determine the ideal bedtime to ensure you get the recommended amount of sleep and wake up feeling rested.

Genetics also plays a role in determining the amount of sleep a person needs. This includes whether you are a "lark" (a morning-type individual) or an "owl" (an evening-type person).
If you want to determine the exact amount of sleep you need, you can try a "sleep vacation". During a two-week period, pick a consistent bedtime and do not use an alarm clock to wake up. You will likely sleep longer at first because you'll be paying off your "sleep debt". Eventually, you will establish a pattern of sleeping the same amount of time each night, probably in the range of 7 to 9 hours.

Sleep schedules
The amount of sleep you need varies from person to person, but for most adults, the ideal number is between 7 and 9 hours. Genetics and age are the two most important factors in determining how much sleep a person needs. Genetics influences both the amount of sleep a person needs and their preference for waking up early or staying up late. These are known as "larks" or "owls".
To determine how much sleep you need, you can try a "sleep vacation". During a two-week period, pick a consistent bedtime and do not use an alarm clock to wake up. For the first few days, you will likely sleep longer to pay off your "sleep debt". If you continue going to bed at the same time and allowing your body to wake up naturally, you will eventually establish a pattern of sleeping the same amount of time each night.
Another way to determine your ideal sleep schedule is to consult a healthcare professional or sleep specialist, especially if you have any other medical conditions. They can help you figure out how much sleep you need and offer advice on improving your sleep quality.
Once you know how much sleep you need, it's important to stick to a consistent sleep schedule. This means going to bed and waking up at the same time every day, including weekends. This will help regulate your body's internal clock and improve your sleep quality.
