(HealthDay News) -- Making sure that your bedsheets smell nice may help you drift into a sweeter sleep.

The National Sleep Foundation suggests:

• Wash sheets and pillow cases at least once weekly, so they always smell fresh.
• Have a second set of quality sheets to use when one set is in the wash.
• Use a laundry detergent that smells pleasant.
• Wash the mattress cover regularly in hot water.
• Use an upholstery cleaner to freshen the mattress, or sprinkle baking soda on the mattress, then vacuum.
• Wash your pillows regularly.
