The American Academy of Sleep Medicine has recommended that children aged 6–12 years should regularly sleep 9–12 hours per 24 hours and teenagers aged 13–18 years should sleep 8–10 hours per 24 hours.
Teens (14-17 years):
0-2 years old: should go to sleep between 8:00 and 9:00 pm. 3-5 years old: should go to sleep between 7:00 and 8:00 pm. 6-12 years old: should go to sleep between 7:30 and 8:30 pm. 13-18 years old: should go to sleep around 10:00 pm.
So how much sleep is enough? According to Johns Hopkins pediatrician Michael Crocetti, M.D., M.P.H. , teens need 9 to 9½ hours of sleep per night—that's an hour or so more than they needed at age 10.
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.
For most of us, five hours of sleep is not OK. Most adults need about eight hours of sleep. And while some people need five hours, it's extremely rare. For most of us, five hours of sleep can lead to sleep deprivation, low energy, poor focus, and long-term health issues.
While most adults need between seven and nine hours of sleep, some adults average five or fewer hours of sleep each night. While it may seem like enough sleep, regularly getting only five hours of sleep each night may lead to sleep deprivation.
More than half of teen ages 15 and older sleep less than seven hours per night, and about 85% of teens get less than the recommended 8-10 hours of sleep per night. Age 14-15 seems to be a big turning point for sleep deprivation, a year when teens experience the greatest drop in hours of sleep per night.
Their internal sleep clock shifts to a later bedtime during the teen years. The body releases the sleep hormone melatonin later at night in teens than in kids and adults. This resets the body's internal sleep clock so that teens fall asleep later at night and wake up later in the morning.
Adults should try to go to sleep between 10:00 and 11:00 p.m.
The answer to this question is an emphatic no. Most people will still be impaired from sleep deficiency even if they sleep for more than twice this amount.
According to their internal body clock, most older adults need to go to sleep around 7 p.m. or 8 p.m. and wake up at 3 a.m. or 4 a.m. Many people fight their natural inclination to sleep and choose to go to bed several hours later instead.
Sleep deprivation increases the likelihood teens will suffer myriad negative consequences, including an inability to concentrate, poor grades, drowsy-driving incidents, anxiety, depression, thoughts of suicide and even suicide attempts.
Oversleeping, or long sleeping, is defined as sleeping more than nine hours. View Source in a 24-hour period. Hypersomnia. View Source describes a condition in which you both oversleep and experience excessive sleepiness during the day.
Elon Musk says he's upped his sleep to 6 hours per night—and that his old routine hurt his brain. Elon Musk, CEO of Tesla, speaks with CNBC on May 16th, 2023. Elon Musk says his days of trying to sleep less and work more are over — at least, relatively speaking.
Experts recommend that adults sleep between 7 and 9 hours a night. Adults who sleep less than 7 hours a night may have more health issues than those who sleep 7 or more hours a night.
Research has shown that adolescence brings with it a shift in biological sleep patterns. Thanks to changing circadian rhythms at this stage, teens naturally get tired later on at night. It's also harder for their bodies to wake up in the mornings.
Studies show people who are sleep deprived report increases in negative moods (anger, frustration, irritability, sadness) and decreases in positive moods. And sleeplessness is often a symptom of mood disorders, such as depression and anxiety.
Growth hormone will be secreted at 12 o'clock at night with the condition that the child sleeps deeply, so the child must be asleep for 2 hours before this time. In addition, parents can optimize their child's height in the following ways: Supplement with an abundant source of calcium.
“There is no such thing as a “fixed or ideal time” to go to bed which will suit all individuals. It is generally advisable to fall asleep between 10 pm to midnight as for most people this is when the circadian rhythm is at a point that favours falling asleep.”
Sleep and Aging
Older adults need about the same amount of sleep as all adults—7 to 9 hours each night. But, older people tend to go to sleep earlier and get up earlier than they did when they were younger. There are many reasons why older people may not get enough sleep at night.
This all depends upon how late, and how regular, a person's sleep patterns are. For example, falling to sleep at 4 am and waking at 12 pm will cause a person to miss out on a large amount of daylight, especially in winter. This can be problematic for various reasons, including our physical and emotional health.
