What is a common myth regarding exercise and sleep?

1. Exercising too late can impact sleep quality

2. Exercise is unnecessary for good sleep

3. You should exercise right before bedtime

4. Exercise helps you fall asleep faster

The correct answer is: You should exercise right before bedtime

A common myth regarding exercise and sleep is that you should exercise right before bedtime. This belief stems from the idea that physical activity can help tire you out, leading to better sleep. However, for many individuals, exercising too close to bedtime can stimulate the body and mind, potentially making it more difficult to wind down and fall asleep. Engaging in rigorous exercise increases heart rate, boosts adrenaline, and raises body temperature, all of which can interfere with the natural processes that prepare the body for sleep. For most people, it is advisable to schedule exercise earlier in the day or to choose lower-intensity activities if working out close to bedtime. In contrast, exercising regularly is known to promote better sleep quality overall, as it helps to regulate sleep patterns and reduce stress and anxiety, which can be beneficial for sleep. Thus, while activity is important for good sleep hygiene, timing it right is crucial for optimizing its benefits.
