SLEEPING IN A COLD ROOM MIGHT BE BAD FOR YOU: A Japanese study finds sleeping in a cold room could actually be bad for your health. Researchers found that people who slept in a 57-degree room overnight saw their blood pressure rates jump six to eight percent after climbing out of bed in the morning compared to sleepers who slept in a 76-degree room. Researchers say the spike in blood pressure lasts at least two hours and over time can put a strain on the heart. Study coauthor, Dr. Keigo Saeki, an epidemiologist at Japan's Nara Medical University, says when you get out of bed in a cold room the blood vessels in your skin constrict, and your heart speeds up in an attempt to warm the body.
