Who doesn’t enjoy a little late night channel surfing? According to Pennsylvanian researchers, it’s the top late-night activity and one that takes up close to half of the two pre-bedtime hours. Researchers also noted late night viewing results in chronic sleep debt and that viewers were prone to sleeping in and going into work late in an attempt to compensate for lost time. Our advice: Tune out Leno or TiVo it. If you think getting quality sleep is difficult now, it only gets tougher if you’re suddenly unemployed in today’s job market.
