As we age, our sleep patterns change. Older people often sleep less or wake up more frequently throughout the night. A 2008 study found that 60-72-year-olds slept for an average of 7.5 hours a day, while 18-32-year-olds slept for almost nine hours. However, it's unclear whether older people need less sleep or if they have a greater sleep debt. The National Sleep Foundation recommends seven-to-nine hours of sleep a night for adults up to 64 and seven-to-eight hours for those over 65. Sleep problems in older adults can be addressed through cognitive behavioural interventions or sleeping pills.

What You'll Learn
Circadian rhythms and age
It is a common misconception that older people need less sleep. In fact, the National Sleep Foundation in the US recommends seven-to-nine hours of sleep a night for adults up to the age of 64 and seven-to-eight hours for those over 65. However, it is true that people often begin to sleep less as they get older, or wake up more frequently throughout the night. This could be due to changes in the processes underlying circadian rhythms as we age, but more research is needed to confirm this.
A 2008 study at Brigham Women's Hospital in the US found that 60-to-72-year-olds slept for an average of 7.5 hours each day, while 18-to-32-year-olds slept for almost nine hours. However, it is unclear whether this means that older people need less sleep, or simply that they were more tired and had a greater sleep debt.
There are two main difficulties that older people face when it comes to sleep: falling asleep at the start of the night and then waking up too early in the morning, unable to get back to sleep. This can be exacerbated by medical conditions or physical symptoms, but many find that even without these disturbances, sleep still eludes them for at least part of the night.
A lack of sleep can have a long-term impact on the immune system and other aspects of health, including wellbeing, and can lead to daytime sleepiness and an increased risk of accidents. Cognitive behavioural interventions for sleep problems have been found to be effective in some cases for adults over the age of 60, and are worth considering as an alternative to sleeping pills.

Sleep problems in older adults
It is a common misconception that older people need less sleep. In fact, the National Sleep Foundation in the US recommends seven-to-nine hours of sleep a night for adults up to the age of 64 and seven-to-eight hours for those over 65. However, many older people experience difficulties falling asleep and staying asleep throughout the night. This can be due to a variety of factors, including medical conditions, discomfort, or changes in circadian rhythms.
A 2008 study at Brigham Women's Hospital in the US found that 60-to-72-year-olds slept for an average of 7.5 hours a day, while 18-to-32-year-olds slept for almost nine hours. This suggests that older people may indeed need less sleep, but it is also possible that younger people were more tired due to greater sleep debt.
If you are an older adult experiencing sleep problems, it is important to take this seriously and seek help if needed. There are a variety of strategies that can improve sleep, including establishing a bedtime routine, creating a comfortable and relaxing sleep environment, and avoiding stimulating activities before bed.

Sleep debt in younger adults
It is a common misconception that older people need less sleep. In fact, the National Sleep Foundation in the US recommends seven-to-nine hours of sleep a night for adults up to the age of 64 and seven-to-eight hours for those over 65. However, it is true that older people often sleep less or wake up more frequently throughout the night. This could be due to changes in the processes underlying circadian rhythms as we age.
Sleep debt is a term used to describe the cumulative effect of not getting enough sleep. A 2008 study at Brigham Women's Hospital in the US found that 18-to-32-year-olds slept for almost nine hours when given the chance to sleep for 16 hours a day for several days. This suggests that younger adults may need more sleep than older people and that they could be more tired out with a greater sleep debt.
The impact of sleep debt can be significant, leading to daytime sleepiness and an increased risk of accidents. It can also have long-term effects on the immune system and overall health and wellbeing. Therefore, it is important for younger adults to prioritise getting enough sleep to avoid sleep debt and its associated consequences.
There are various strategies that younger adults can employ to manage their sleep debt. This includes cognitive behavioural interventions, which have been found to be effective in some cases for adults over the age of 60. By addressing sleep difficulties early on, younger adults can mitigate the impact of sleep debt on their overall health and wellbeing.

Medical conditions and sleep
Sleep is a vital part of our lives, and the amount we need can vary depending on our age, lifestyle, and medical conditions. While it is commonly believed that older people need less sleep, the scientific evidence is inconclusive. Some studies suggest that older adults may sleep less due to changes in their circadian rhythms, while others indicate that they may simply find it more challenging to fall asleep or stay asleep throughout the night.
Medical conditions can significantly impact sleep quality and duration. Discomfort caused by physical symptoms can disrupt sleep, making it difficult to fall asleep or maintain a restful slumber. Even without the presence of specific medical conditions, some individuals may struggle with insomnia or other sleep disorders.
The relationship between medical conditions and sleep is complex. Sleep disturbances can be a symptom of an underlying medical issue, or they may contribute to the development or exacerbation of certain health conditions. For example, a lack of sleep has been linked to a weakened immune system, affecting overall health and well-being. It can also lead to daytime sleepiness, impacting an individual's productivity and increasing the risk of accidents.
In older adults, sleep problems may be more prevalent due to age-related changes in sleep architecture and the presence of medical conditions. A Cochrane review found that cognitive behavioural interventions can be effective in managing sleep issues in adults over 60, offering an alternative to sleeping pills.
While the exact amount of sleep needed may vary, it is essential to prioritise sleep hygiene and seek professional advice for persistent sleep difficulties. Adequate sleep is crucial for maintaining physical and mental health, and addressing sleep issues can improve overall well-being.

Sleep and the immune system
Sleep is an essential part of our lives, and the amount we need changes as we age. While it is a common belief that older people need less sleep, there is no scientific consensus on this. A 2008 study at Brigham Women's Hospital in the US found that 60-to-72-year-olds slept for an average of 7.5 hours each day, while 18-to-32-year-olds slept for almost nine hours. However, it is unclear whether this means older people need less sleep or if they have accumulated greater sleep debt over time.
The National Sleep Foundation in the US recommends seven-to-nine hours of sleep per night for adults up to 64 years old and seven-to-eight hours for those over 65. Sleep difficulties can be caused by medical conditions or other disturbances, and a lack of sleep can have a long-term impact on the immune system and overall health. Cognitive behavioural interventions have been found to be effective in treating sleep problems in adults over 60, offering an alternative to sleeping pills.
As we age, we may experience more difficulty falling asleep at the start of the night and staying asleep, leading to frequent waking throughout the night. While the reasons for these changes are not fully understood, they may be related to alterations in our circadian rhythms as we grow older.
In summary, while it is unclear if older people need less sleep, it is known that sleep patterns change with age. Sleep difficulties can have a significant impact on health and well-being, and it is important to address them. Treatments such as cognitive behavioural interventions offer hope for improving sleep quality in older adults.

Frequently asked questions
It's a common misconception that older people need less sleep. While some people do find they sleep less as they get older, it's not necessarily because they need less sleep. The National Sleep Foundation in the US recommends seven-to-nine hours of sleep a night for adults up to the age of 64 and seven-to-eight hours for those over 65.
There are a few reasons why older people might sleep less. One reason could be changes in the processes underlying circadian rhythms as we age. Another reason could be discomfort caused by medical conditions, which can make it difficult to fall asleep or stay asleep for a full night.
Not getting enough sleep can have a long-term impact on your health and well-being. It can lead to daytime sleepiness and an increased risk of accidents. It can also affect your immune system, making you more susceptible to illness.
