Verified step by step guidance

1. Step 1: Understand the factors that influence sleep quality by reviewing common psychological and physiological influences on sleep patterns.
2. Step 2: Recognize that exposure to bright screens before bedtime can affect the production of melatonin, a hormone that regulates sleep-wake cycles.
3. Step 3: Compare the impact of other options such as regular physical activity, drinking water, and eating a balanced breakfast on sleep quality, noting that these generally support overall health but do not directly disrupt sleep.
4. Step 4: Identify that blue light emitted from screens suppresses melatonin production, leading to difficulty falling asleep and reduced sleep quality.
