As with many facets of the human body, there is no one-size-fits-all strategy to sleep. Overall, research recommends that for healthy young adults and adults with normal sleep patterns, 7–9 hours is suitable. And if you feel drowsy during the day, even during boring activities, you haven’t had enough.
How much sleep do I need?
The amount of sleep individuals need depends on many things, including their age. As a general guideline, individuals need approximately the following hours per day of sleep:
- Infants (ages 0-3 months): 14-17 hours
- Infants (ages 4-11 months): 12-15 hours
- Toddlers (ages 1-2 years): 11-14 hours
- Preschool children (ages 3-5): 10-13 hours
- An elementary school-age child (ages 6-13): 9-11 hours
- Teens (ages 14-17): 8-10 hours
- Most adults: 7 to 9 hours
- Some adults: may need as few as 6 hours or as many as 10 hours
- Older adults (ages 65 and older): 7-8 hours
- Pregnant women: Several more hours of sleep than usual
But what about athletes and those starting or maintaining an exercise regimen? How much sleep do I need? Let’s look at some recent studies’ recommendation for an athlete’s basic needs and ideal optimization on the science of sleep.
Sleep designed to improve athletic performance and recovery
- Sleep longer at night (sleep extension).
- Sleep time during the day (napping).
- Quality sleep (sleep hygiene).
Effects of sleep deprivation on endurance cycling performance
Sleep helps you perform better. Simply put, the more you sleep, the better impact on performance and recovery. If you want to be an elite athlete, you likely need to increase sleep duration and cannot catch up on the weekend from long term sleep deprivation. Researchers also found evidence that the subjective rate of perceived exertion was higher on day 2 of sleep deprivation than on day 1. Athletes felt like they were working harder than they were because of the sleep schedule.
Napping in athletes
Athletes’ napping is not necessarily due to sleepiness, as referenced in the introduction. They are an anomaly given the demands of their sport. Elite athletes learn to have a higher capacity for a nap on demand. While good athletes have similar individual sleep habits, but it’s more variable.
Factors such as school work, extracurricular activities, and athletics may prevent adequate sleep, and adolescents need more than adults. Young athletes are at increased risk for a sleep disorder, and more research is required to determine the effects of training schedules and competitions on sleep.
Train hard, sleep well in each stage
Training load was not associated with sleep duration but was associated with wake after sleep onset. Deep sleep increased in proportion to the training load. The current study indicates that sleep quantity and sleep stage distributions remain unrelated to variations in perceived training load.
