Neurologist: Naps are crucial but not a substitute for sleep debt

Pablo Ferrero, a neurologist specializing in sleep medicine, emphasizes that while 7 to 8 hours of sleep is optimal, naps should not be used to compensate for chronic sleep deprivation.

Ferrero warns that extended naps, particularly on weekends to make up for lost sleep during the week, can disrupt the body's natural circadian rhythm. He cites NASA's recommendation of a 26-minute nap as the ideal duration, a figure widely accepted in sleep medicine.

The neurologist also highlights the importance of the sleep environment, stressing that mattress choice is critical. He suggests spring mattresses offer better breathability. Ferrero advises consumers to test mattresses in stores for at least 15-20 minutes to ensure proper spinal alignment, noting that the spine's natural 'S' shape requires adequate support.

Further recommendations include using pillows with distinct heights to support the neck and head, and opting for cool fabrics on cervical supports to aid temperature regulation. For sleeping position, Ferrero suggests sleeping on one's back if health conditions like snoring or sleep apnea do not contraindicate it. If turning is necessary, the left side is preferred to minimize reflux and digestive issues. Maintaining a cool room temperature (19-21 degrees Celsius) and complete darkness are essential for restorative sleep.
