SWell, seven to nine hours of sleep per night is typically recommended for adults, at any age, but each life stage has its own set of biological, cognitive and developmental needs.
With this in mind, some experts, quoted by The Independent newspaper, revealed the number of hours you should sleep depending on your age.

Between 18 and 25 years old
“During this stage, cognitive functions, emotional regulation and maturation of the brain’s prefrontal cortex (responsible for decision-making and impulse control) are strongly affected by adequate sleep,” explains sleep therapist Dennis Iordash.
This means, he adds, that “between seven and nine hours of sleep are needed each night to support brain development, learning and memory enhancement.”
Age between 26 and 44 years
“During this stage, the circadian rhythm stabilizes, with most adults able to maintain regular sleep patterns.” He further explains that “melatonin production begins to decline slightly with age, but sleep-wake cycles remain relatively stable.” It is important to maintain consistent bedtime and wake-up times.
“Adequate sleep during this period is important for cognitive function, physical health, and stress management,” explains Theresa Schnorbach, a psychologist and sleep specialist.

– Between 45 and 59 years old
“People ages 45 to 59 may need more sleep to feel fully rested and recover from daily activities,” he says. “They may also have more difficulty falling asleep and staying asleep.”
Furthermore, people in this age group may start going to bed earlier because “circadian rhythms may begin to change, with a tendency to feel tired earlier in the night.”
Over 60 years old
“During this stage of life, sleep becomes essential for maintaining cognitive function and immune health,” Yordash explains. It's important because “aging bodies need more time to recover, but factors such as health conditions, medication use, and changes in circadian rhythms can affect sleep patterns.”
