Forget All-Night Studying, a Good Night’s Sleep Is Key to Doing Well on Exams
As fall semesters wind down at the country’s colleges and universities, students will be pulling all-night study sessions to prepare for final exams. Ironically, the loss of sleep during these all-nighters could actually work against them performing well, says a Harris Health System sleep specialist.
Dr. Philip Alapat, medical director, Harris Health Sleep Disorders Center, and assistant professor, Baylor College of Medicine, recommends students instead study throughout the semester, set up study sessions in the evening (the optimal time of alertness and concentration) and get at least 8 hours of sleep the night before exams.
“Memory recall and ability to maintain concentration are much improved when an individual is rested,” he says. “By preparing early and being able to better recall what you have studied, your ability to perform well on exams is increased.”
Alapat’s recommendations:
• Get 8-9 hours of sleep nightly (especially before final exams)• Try to study during periods of optimal brain function (usually around 6-8 p.m.)
• Avoid studying in early afternoons, usually the time of least alertness
• Don’t overuse caffeinated drinks (caffeine remains in one’s system for 6-8 hours)
• Recognize that chronic sleep deprivation may contribute to development of long-term diseases like diabetes, high blood pressure and heart disease
If suffering from bouts of chronic sleep deprivation or nightly insomnia that lasts for more than a few weeks, Alapat suggests consulting a sleep specialist.
