Most adults need seven to nine hours of sleep each night, but more than one-third consistently sleep fewer than seven. Reasons for poor sleep include pregnancy, menopausal night sweats, medication use, sleep disorders, and various illnesses.

To promote sounder sleep, people can keep consistent sleep-wake schedules, reduce intake of caffeine and alcohol, and avoid using electronic devices before bed.

Doctors concentrate on helping men lower their blood levels of low-density lipoprotein (LDL), or "bad" cholesterol, to lower their risk of cardiovascular disease.

However, no specific therapies to raise HDL levels have improved outcomes.
