Question

1. how does physical activity affect sleep patterns?

a. it reduces the need for sleep
b. it disrupts sleep patterns
c. it has no impact on sleep
d. it leads to deeper and more restful sleep

Explanation:

Physical activity helps in better sleep. It does not reduce the need for sleep (a is wrong). Regular physical activity (not overly - strenuous close to bedtime) does not disrupt sleep (b is wrong). It has a positive impact on sleep (c is wrong). Physical activity can lead to deeper and more restful sleep as it tires the body in a healthy way and can regulate the sleep - wake cycle.

Answer:

d. It leads to deeper and more restful sleep
