Waiting until you feel sleepy working at a computer late at night before going to bed is not a dreamy idea. Ditto, taking a laptop to bed and falling asleep. These behaviors (and others like them) ruin sleep quality. Repeated research has warned that lack of sleep increases your risk of health problems such as cancer, heart disease, type 2 diabetes, and even obesity. Recommendations from National Sleep Foundation you may want to practice include the following: 1) participating in a ritual of preparing for sleep each night before climbing into bed, and 2) going to bed at the same time each night, even on weekends or days off. Also, have a routine in the morning when you wake up. Start tonight, and see if these suggestions don't improve your sleep quality. See a doctor if sleep issues persist.
