Question

one key to the use of exercise in aiding good sleep is that ____________. a. muscles contain sleep - inducing hormones b. it is easier to sleep when one is tired c. delta brain waves are generated by exercise d. only cardiovascular activities aid sleep please select the best answer from the choices provided

Explanation:

• Option A: Muscles do not contain sleep - inducing hormones. Sleep - inducing hormones like melatonin are mainly produced by the pineal gland.
• Option B: When a person is tired (for example, after exercise which can cause physical exertion), it is often easier to fall asleep. This is a common and logical connection.
• Option C: Delta brain waves are associated with deep sleep, but they are not generated directly by exercise. They occur naturally during the sleep cycle.
• Option D: It is not true that only cardiovascular activities aid sleep. Other types of exercise (such as strength training in moderation) can also contribute to better sleep.

Answer:

B. it is easier to sleep when one is tired
