The phrase "to establish good sleep habits" refers to developing and maintaining a regular routine that promotes healthy sleep patterns. This includes going to bed at the same time each night, creating a comfortable sleep environment, avoiding stimulants such as caffeine or electronic devices before bedtime, and getting enough physical activity during the day. Establishing good sleep habits is important for overall well-being, mental health, and physical health, as lack of sleep can lead to fatigue, irritability, weight gain, and other negative consequences.
