As you age, your sleep needs stay remarkably consistent, with most adults needing 7-9 hours of sleep, and older adults (65+) generally needing 7-8 hours, similar to younger adults, though sleep patterns often change, making it harder to get consistent rest. While the amount needed doesn't drastically decrease, factors like health, medications, and lifestyle changes can disrupt sleep, leading to more waking during the night or earlier bedtimes, notes this Yale Medicine article.
Older adults need about the same amount of sleep as all adults — seven to nine hours each night. But older people tend to go to sleep earlier and get up earlier than they did when they were younger. Getting enough sleep helps you stay healthy and alert.
The 3-2-1 sleep rule is a simple wind-down routine: stop eating and drinking alcohol 3 hours before bed, stop working/mentally stimulating activities 2 hours before, and turn off screens (phones, TVs) 1 hour before sleep, helping you transition to rest by reducing stimulants and preparing your mind and body. It's often part of a larger 10-3-2-1-0 rule, which also adds no caffeine 10 hours prior and no hitting snooze (0) in the morning.
While some people regularly function on short periods of sleep, research mostly agrees that six hours of sleep is not enough for most adults. Experts recommend that most adults need at least seven hours of sleep every night.
According to a new study, some people who function normally on just 6 hours of sleep harbor an altered version of a particular gene, the second gene so far linked to short sleep.
Symptoms of Sleep Deprivation
Keep your room cool, dark and quiet. Exposure to light in the evenings might make it more challenging to fall asleep. Avoid prolonged use of light-emitting screens just before bedtime. Consider using room-darkening shades, earplugs, a fan or other devices to create an environment that suits your needs.
Signs of poor core sleep (deep, restorative sleep) include waking up foggy, daytime fatigue/energy crashes, poor concentration, irritability, frequent illness, memory issues, and mood swings, indicating your brain and body aren't fully repairing and consolidating memories. You might also experience increased sugar cravings, slow muscle recovery, and a weakened immune system.
The 40s and 50s
Both fluctuations can result in lower energy levels, feeling lethargic, and less muscle mass. Again, the 40s and 50s impact people differently, with some noticing fewer effects than others. However, during this stage, people will usually notice they're "getting old".
Depending on one's age and individual needs, the National Sleep Foundation (USA) states that adults need seven to nine hours of good quality sleep per night to remain healthy and alert. School-age children require between nine and eleven hours, while older adults may need only seven to eight.
The koala is famous for sleeping around 20-22 hours a day, which is about 90% of the day, due to their low-energy diet of eucalyptus leaves that requires extensive digestion. Other extremely sleepy animals include the sloth (up to 20 hours) and the brown bat (around 20 hours), with some snakes like the ball python also sleeping up to 23 hours daily.
For older adults, naps are good
“There's a lot of evidence that in adults 65 or older in particular,” said Dr. Rowley, “they don't get all the sleep that they need at night because of aging effects.”
Best survival rates were found among those who slept seven hours a night. A group sleeping eight hours was 12% more likely to die within the six year period than those sleeping seven hours, other factors being equal. Even those with as little as five hours lived longer than those with eight hours or more nightly.

The 3-2-1 bedtime method is a simple sleep hygiene strategy: stop eating 3 hours before bed, stop working 2 hours before bed, and stop using screens (phones, tablets, TVs) 1 hour before sleep, helping your body transition to rest by reducing stimulants and digestive load for better sleep quality. A more detailed version adds 10 hours (no caffeine) and 0 (no snoozing) for a 10-3-2-1-0 rule.
The "3-2-1 Bedroom Method" (or a variation like the 10-3-2-1 rule) is a sleep hygiene strategy to improve rest by staggering when you stop certain activities before bed: stop heavy food/alcohol 3 hours before, stop work/mental stress 2 hours before, and turn off screens (phones, TVs, computers) 1 hour before sleep, creating a better wind-down for your body.
My personal routine is get ready for bed at 10pm (I sleep a lot so this can seem quite early), which involves: *taking meds *brushing teeth *unplugging everything in the house *Tidying room *preparing bags for the next day (although this could be part of a morning routine too) *getting into pyjamas *hanging clothes up ...
Own Your 3-Foot Space In Navy SEAL training, there's a simple but profound principle: Own your 3-foot space. It means focusing on what's directly within your control—your actions, your attitude, your effort—no matter how chaotic the environment around you becomes.

A prime example is the box breathing technique, famously used by the Navy Seals, known as the 4-4-4-4 method. This simple yet effective method involves a cycle of inhaling for 4 seconds, holding the breath for 4 seconds, exhaling for 4 seconds, and then pausing for 4 seconds before the next inhalation.
