Can sleeping too much be bad for your health?

Regularly sleeping unusually long hours has been associated with poorer health outcomes, but that does not mean extra sleep itself is necessarily harmful. Research shows that both short and long sleep durations can be linked with biological aging, disease risk, and mortality, while also leaving open the possibility that underlying illness is causing people to sleep longer. Occasional long sleep may be appropriate after sleep loss or during illness, but consistently needing much more sleep than usual, especially when you still feel tired, may be a sign that something else is affecting sleep quality or health. The article emphasizes that hours spent in bed are only part of the picture and that persistent changes in sleep duration or daytime alertness are worth discussing with a healthcare professional.
