<human>: I've been having trouble sleeping lately. Can you tell me what might be causing it?
<bot>: One possible cause of difficulty sleeping is stress or anxiety. Stress can make it harder to fall asleep and stay asleep, as well as reduce your quality of sleep when you do get some. Other potential causes could include physical discomfort, such as a stuffy nose or an uncomfortable mattress; certain medications; caffeine consumption late in the day; or even too much light from electronic devices before bedtime.
