Final answer:
Sleep is not the only thing that can overcome fatigue. While sleep is important for restoring and recovering the body's functions, there are other ways to combat fatigue.
Step-by-step explanation:
Sleep is not the only thing that can overcome fatigue. While sleep is important for restoring and recovering the body's functions, there are other ways to combat fatigue. For example, taking breaks, engaging in physical activity, eating healthy, and staying hydrated can all help reduce fatigue.
In terms of a relationship between sleep duration and level of activity, individuals who get enough sleep tend to have higher energy levels and may be more active. On the other hand, individuals who consistently lack sleep may feel fatigued and have lower levels of activity
Therefore, the statement that sleep is the only thing that can overcome fatigue is false.
