How Sleep Impacts Athletic Performance
When athletes consider the factors that will allow them to reach optimal performance levels in their given sport, they often put weight on their nutrition program, training process, and hydration. They often forget that sleep is a major factor in improving an athlete’s physical and mental performance on the field.
Sleep plays a crucial role in athletic performance and overall health. Let’s take a closer look at the role of sleep in the human body, the key impacts of sleep on performance, and how much sleep is an adequate amount for an athlete.
The Role of Sleep on the Human Body
Every night, our bodies go dormant to perform critical maintenance on both cognitive and physical levels. What may seem like a time of rest is actually a time when the brain is incredibly busy storing new information, deleting old information, and mentally practicing new skills. On a physical level, sleep allows the body to clear brain toxins that have built up during the day, strengthen the immune system, and repair cells and tissue. According to the National Institute of Health, a chronic lack of sleep is associated with increased risks of obesity, heart disease, and cognitive decline.
Key Impacts of Sleep on Performance
For athletes who hope to maintain optimal performance, sleep is just as essential as a training regimen, a nutritional plan, or hydration. An athlete’s body is under constant strain and wear and tear, making sleep an important time for repair and maintenance.
Physical Recovery
Among the benefits of a good night’s sleep for athletes and non-athletes alike is a chance for physical recovery. Over the course of a typical day, the body breaks down hundreds of tiny muscles during activities such as walking, biking, or running. Human growth hormone is important for tissue repair and for muscle and bone development. It’s only secreted during deep sleep.
For athletes to push their bodies to go faster and work harder during every training session, practice, and game, the recovery process is even more important. Mass General Brigham explains that “an athlete’s body repairs muscles best when it spends about 50% or more of its time asleep in deep sleep. Without enough time in this stage, their body may not fully repair, leaving them feeling ready to train at nearly the same level as the day before.“
Additionally, the “stress hormone,” cortisol, is hard on the body, and sleep decreases it. The result is less frequent illness and faster recovery, the better the quality of an athlete’s sleep.
Mental Recovery
Sleep helps humans retain and consolidate memories. When athletes practice or learn new skills, sleep helps form memories and contributes to improved performance in the future. Overall, sleep improves focus, needed both on and off the field, motor memory, and decision-making, while lack of sleep reduces coordination and mental sharpness.
How Much Sleep is Enough?
The amount of sleep needed to maintain health varies by age and life stage. Children, age 6-12, generally need 9-12 hours of sleep, while teens ages 13–18 should get 8-10 hours of sleep. Adults should aim for 7-9 hours of sleep. Due to high-intensity training, athletes may require more sleep, often exceeding 9-10 hours to prevent injury.
Sleep is a vital, often-overlooked component of athletic success, serving as a crucial time for both physical and mental recovery. It is during deep sleep that the body secretes human growth hormone for muscle repair, reduces the stress hormone cortisol, and consolidates memories to improve focus and decision-making. Given the high demands of training, athletes may need 9-10 hours of sleep to ensure full recovery and prevent injury.
