In one sentence, describe what the following article is about:

Anxiety is one of the most common causes of sleep talking, so reducing your stress levels during the day might be enough to put a stop to your late-night monologues. There are multiple ways to reduce stress in your daily waking life. Removing causes of stress often helps, but when that isn't possible, learn practices to help relax your mind and body. Meditation, yoga, and regular massages are a few such options. Moderate physical activity can help regulate your mind and body. Try walking at a brisk pace for 15 to 20 minutes each day. Schedule these walks for the morning, late afternoon, or early evening. Avoid exercising shortly before bed, however. Cardiovascular exercise, in particular, stimulates your circulation and may make you feel more awake for a brief period of time. For that reason, you should exercise no later than one to two hours before your intended bedtime. Spend more of your waking hours in natural, indirect sunlight. Try to soak in at least six to eight hours of daylight on a daily basis. By getting more sunlight during the day, you can help your brain associate “light” with “wakefulness” and “dark” with “sleep.” After several weeks of increased daylight, you may notice yourself feeling more awake during the day and more tired when it's time to sleep. This could lead to deeper, more relaxed sleep, which typically involves less sleep talking.

Summary:
Minimize emotional stress. Exercise during the day. Regulate your light intake.
