What You'll Learn
The recommended sleep for adults is 7-9 hours
For a 38-year-old female, the recommended sleep range remains the same as for other adults: 7–9 hours. This guideline is based on public health recommendations, but internal and external factors can influence how much shut-eye an individual needs.
Sleep is essential for maintaining good mental health and wellbeing, and it becomes particularly crucial as we age to avoid cognitive decline. Research has linked both too little and too much sleep with impaired cognitive performance, including in areas such as problem-solving, memory, and processing speed.
The amount of sleep we need can vary with age, with infants, young children, and teenagers requiring more sleep to support their growth and development. Additionally, our sleep requirements can be influenced by factors such as our activity levels, overall health, genetics, environment, and health conditions. For instance, women may experience changes in their sleep patterns during pregnancy or menopause due to hormonal changes and physical discomfort.
It's important to prioritize getting sufficient sleep to stay happy, healthy, and mentally sharp. However, it's worth noting that some people are short sleepers and can function well with less than seven hours of sleep, while others may need nine hours or more.
To determine your optimal sleep need, reflect on how much sleep leaves you feeling refreshed and able to function optimally during the day. This self-awareness can help you set a bedtime that ensures you get the recommended 7–9 hours of sleep as a 38-year-old female.

Sleep needs vary based on genetics, environment, and health
Sleep is essential, and the amount of sleep one needs varies from person to person. While most adults require approximately 8 hours of sleep per day, individual sleep needs may range from 6 to 9 hours. This variation in sleep requirements is influenced by various factors, including genetics, environment, and health.
Genetics play a significant role in determining sleep needs. Our internal biological clock, or circadian rhythms, is regulated by our genes and influences the timing of functions such as sleep and wake cycles, appetite, hormone release, and metabolism. Individual differences in circadian rhythms have been linked to variations in the speed of our internal clocks. For example, individuals with a circadian clock faster than 24 hours tend to be "larks" or early risers, while those with a slower clock tend to be "owls" or night owls. Additionally, certain genetic variations have been associated with sleep disorders such as sleep apnea and an increased vulnerability to the adverse effects of sleep loss.
Environmental factors also contribute to varying sleep needs. To achieve optimal sleep, individuals require a conducive sleep environment that is free from external disruptions. Factors such as noise, light, temperature, and humidity can impact sleep quality. For instance, research suggests that intermittent noise, particularly above 35 dB, can disrupt sleep, while continuous noise may be less disruptive. Complete darkness and an ambient temperature between 17°C and 28°C at 40–60% relative humidity are optimal for sleep. Additionally, blue light should be avoided, and air quality and ventilation are important considerations for a sleep-conducive environment.
Health and overall well-being also influence how much sleep an individual needs. Age is a significant factor, with different age groups having different sleep requirements. Additionally, activity levels and overall health can impact sleep needs. Certain health conditions, such as cardiovascular disease, depression, pain, and diabetes, may require specific sleep considerations. It is important to prioritize sleep and make adjustments to one's lifestyle and environment to ensure adequate sleep.
While the recommended sleep range for adults is generally 7 to 9 hours, it is important to listen to your body and reflect on your individual needs. Sleep is essential for maintaining good mental and physical health, and getting too little or too much sleep can impact cognitive performance. Understanding your personal sleep needs and creating a sleep-conducive environment can help improve sleep quality and overall well-being.

Sleep patterns for women change during pregnancy and menopause
For adults between the ages of 25 and 64, it is recommended to get an average of 7 to 9 hours of sleep per night. This is based on public health recommendations, and internal and external factors may influence the number of hours of sleep needed. For example, during pregnancy and menopause, women may experience changes in their sleep patterns.
Sleep Patterns During Pregnancy
Pregnancy can bring about significant changes in sleep patterns due to physical discomfort, psychological adjustments, and hormone changes. During the first trimester, many women experience increased fatigue and daytime sleepiness, which may be related to elevated levels of the hormone progesterone and the resulting disruption of sleep. Nausea, vomiting, increased urinary frequency, back pain, breast tenderness, and anxiety can also contribute to sleep difficulties during this time.
In the second trimester, sleep tends to improve, with better sleep efficiency and fewer awakenings during the night. However, towards the end of this period, women may experience irregular contractions or stomach pain that can disrupt sleep.
During the third trimester, nighttime awakenings become more frequent again, and women may experience more daytime napping. Sleep is often lighter, with more time spent in stages 1 and 2 of sleep. Additionally, underlying sleep disorders, such as sleep apnea or restless legs syndrome, may worsen or develop during pregnancy.
Overall, studies have shown that sleep quality tends to deteriorate as pregnancy progresses, with low income, lower vitamin D levels, greater energy intake, and more sedentary behaviour being associated with poorer sleep.
Sleep Patterns During Menopause
Menopause can also significantly impact sleep patterns. During perimenopause, the period before menopause when hormone levels and menstrual periods become irregular, sleep problems can begin. These sleep disturbances often continue throughout the menopausal transition and even after menopause.
Menopausal women commonly experience sleeplessness due to hot flashes, which can cause unexpected awakenings. Additionally, they may be at an increased risk of developing sleep disorders such as sleep apnea and insomnia. Depressive symptoms, anxiety, and hormonal changes can also contribute to poor sleep during this life stage.

Sleep quality tends to deteriorate with age
Most healthy adults need at least seven hours of sleep each night, with the average being between seven to nine hours. This guideline, however, is not limited to age, as children and teenagers require more sleep to support their growth and development.
Several factors contribute to the deterioration of sleep quality with age. Firstly, the body's production of melatonin decreases with age. Melatonin is a hormone that is usually secreted in response to darkness, aiding in sleep by coordinating circadian rhythms. Older adults are also more susceptible to insufficient exposure to daylight, which can further disrupt their circadian rhythms.
Additionally, older adults often experience multiple health conditions, which can impact their sleep. The side effects of medications for these conditions can also contribute to poor sleep quality. Lifestyle changes that come with aging, such as decreased physical activity and social isolation, can further disrupt sleep patterns.
Furthermore, older individuals respond differently to medications, including sleep aids. While antidepressants can be beneficial for sleep in cases of depression, most sleep medicines are not recommended for older adults. Instead, melatonin supplements may be safer for short-term use, aiding in falling asleep more quickly.
To improve sleep quality with age, it is essential to address lifestyle factors. Regular exercise, avoiding stimulants like caffeine, and limiting screen time before bed can all help. Additionally, maintaining a consistent sleep and wake schedule and practising relaxation techniques can improve sleep hygiene and promote better rest.

Older people may develop advanced sleep-phase syndrome
The recommended sleep for a 38-year-old female is between 7 to 9 hours per night, according to the NHS and the National Sleep Foundation. This guideline is based on public health recommendations, but internal and external factors may influence the number of hours needed. For example, factors such as activity level and overall health can affect sleep requirements.
People with advanced sleep-phase syndrome often experience difficulty staying awake unless they go to bed very early. They may also struggle with social activities due to excessive daytime sleepiness. The disorder is believed to have a strong genetic basis, with approximately 40-50% of affected individuals having relatives with the syndrome. Familial advanced sleep phase syndrome (FASPS) is a specific form of the disorder caused by genetic mutations in the hPER2 and CKIdelta genes.
The treatment for advanced sleep-phase syndrome involves delaying the sleep-wake cycle to align with conventional times. Bright light therapy in the evening, typically between 7 and 9 pm, has been shown to be effective in delaying the circadian rhythms of individuals with this syndrome. However, treatment for FASPS has proven largely unsuccessful.
While advanced sleep and wake times are relatively common among older adults, the extreme phase advance characteristic of FASPS is rare. The shortened circadian period associated with FASPS results in a reduced period of activity, causing earlier sleep onset and offset. This means that individuals with FASPS must adjust their sleep and wake times daily to match the standard 24-hour cycle.

Frequently asked questions
Most sources recommend that adults get between 7 and 9 hours of sleep per night. However, the ideal amount of sleep varies depending on factors such as age, health, activity level, and individual needs. According to a new study, 7 hours is the ideal amount of daily sleep for those aged 38 and above.
For women, sleep patterns tend to remain stable until pregnancy or menopause. During pregnancy, hormonal changes and physical discomfort can cause sleep problems. Menopause can also disrupt sleep due to hormonal changes and symptoms such as hot flashes and night sweats. Additionally, primary sleep disorders like insomnia, sleep apnea, and restless leg syndrome tend to worsen with age.
Not getting enough sleep can have adverse health effects. Sleeping less than 7 hours per night regularly is associated with weight gain, obesity, diabetes, heart disease, stroke, depression, and an increased risk of accidents and death. Poor sleep can also impact mental health and cognitive function, affecting areas such as memory, concentration, and mood.
To improve sleep quality, it is important to address any underlying sleep disorders or health conditions that may be disrupting sleep. Additionally, maintaining a consistent sleep schedule, creating a relaxing bedtime routine, and improving sleep hygiene by limiting screen time and creating a comfortable sleep environment can all contribute to better sleep. Regular physical activity, stress management techniques, and establishing a wind-down period before bed can also enhance sleep quality.
