Question

question 133 (1 point)
which of the following is true about the effect of exercise on your quality of sleep?
a) exercising strenuously heats up your body and thereby helps you to fall asleep.
b) exercising strenuously in the morning or afternoon boosts sleep quality.
c) aerobic exercise improves sleep more than aerobic exercise combined with stretching.
d) exercising a couple of hours before sleep improves sleep more than exercising in the morning.

Explanation:

• Option A: Strenuous exercise heats the body but it's the subsequent cooling that helps sleep, not just the heating. So this is incorrect.
• Option B: Exercising strenuously in the morning or afternoon gives the body time to cool down and the endorphin - related energy boost to wear off, which can boost sleep quality. This is correct.
• Option C: Aerobic exercise combined with stretching can have additional benefits for relaxation (from stretching) that may enhance sleep more than just aerobic exercise alone. So this is incorrect.
• Option D: Exercising a couple of hours before sleep may still leave the body too energized (from endorphins and body heat) compared to morning exercise which gives the body a full day to wind down. So this is incorrect.

Answer:

B. Exercising strenuously in the morning or afternoon boosts sleep quality.
