Power Naps for Preschoolers

Tools

Story Updated: Sep 25, 2013

A nap does a preschooler's body...and mind good. That's the headline from a brand new study that looked at the value of a classroom nap. Researchers in Massachusetts recruited a group of 40 preschoolers to measure their visual-spatial memory.

All of the children were asked to play a common game where you look at a grid of pictures and then you have to remember where different pictures are located.

During one testing session, the children napped for an average of 77 minutes in-between viewing the grid and taking the memory quiz. In another, they were kept awake for the same amount of time.

The children did a much better job retaining the location of the pictures after they had taken a nap. The researchers say their findings suggest naps are critical for early learning and they are encouraging educators to develop napping guidelines for young children.

Guthrie Cardiovascular Center

Consistently ranked among the top 100 cardiovascular hospitals by Thomson Reuters, Guthrie cardiologists, cardiac surgeons, and vascular surgeons work together to ensure patients receive the most comprehensive care possible.

Offering cardiovascular care to the Twin Tiers for more than 40 years, Guthrie’s cardiac specialists and staff have offered the people of our region the most advanced diagnostic and therapeutic services possible, while earning national awards for quality and recognition for excellence.

Diagnostic & Non-Invasive Cardiology
Non-invasive cardiology includes all procedures that allow the cardiologist to obtain information about the heart without going through the skin or invading the body in any way. Many times these procedures are the first steps in evaluating a patient's condition. Guthrie provides diagnostic and non-invasive cardiology services, including multi-slice CT angiography, comprehensive mobile echocardiography services including stress echo, EKG, holter monitoring and nuclear stress testing to name a few.

Invasive & Interventional Cardiology
When non-invasive techniques don't provide all the answers, additional diagnostic procedures may be used to more clearly identify and treat cardiac problems. Within Guthrie’s Cardiac Catheterization Laboratories, invasive and interventional cardiologists offer subspecialty diagnostic and therapeutic services to evaluate and treat cardiac conditions without traditional surgery. Guthrie interventional cardiologists perform over 100 peripheral vascular interventions, such as carotid angioplasty and stenting, each year, with a 95% technical success rate.

Electrophysiology & Pacing
The heart's conduction system, the system that controls the rate and rhythm of the heartbeat, can develop problems that interfere with the heart's ability to function properly. Electrophysiology Laboratory team offers complete electrophysiology and pacing services for treatment of arrhythmias – from palpitations and syncope to atrial fibrillation to more specialized rhythm abnormalities.

Cardiac Surgery
Surgery plays an important role in a comprehensive cardiac program. Whatever the patient's needs, they can be met by the Guthrie’s cardiac surgery team. Guthrie’s Cardiac Surgery team provides a comprehensive scope of surgical procedures for the treatment of diseases of the heart and chest. Commonly treated conditions include ischemic heart disease, ventricular aneurysms, valve dysfunction, rheumatic heart disease, cardiac arrhythmia, trauma, cardiac tumors and infection.

Thoracic Surgery
Providing the advanced surgical techniques and oncologic therapies, thoracic surgery at Guthrie is dedicated to the prevention, early diagnosis and treatment of non-cardiac diseases of the chest. We are able to apply the modern techniques of minimally invasive procedures including video-assisted thoracic surgery (VATS) to many disease processes for the diagnosis and treatment of lung cancer and other chest diseases.

Vascular & Endovascular Surgery
Guthrie’s Department of Vascular and Endovascular Surgery offers a full spectrum of services – from life-saving procedures to repair ruptured aneurysms to elective procedures to prevent stroke, provide relief from claudication and address symptoms of venous disease. The latest therapies and minimally invasive endovascular treatment are offered by our experienced vascular team.
