It's a common scenario: a load of laundry is put into the washer only to be forgotten until the next morning. When this happens, clothes often develop a mildewy odor due to the growth of bacteria overnight. However, if clothes still smell fresh and clean, running the load through a second cycle may not be necessary. According to Martha Stewart, it's acceptable to leave wet clothes in the washer overnight, as long as they're not left for too long—certainly not for a week. If transferred to the dryer in the morning, they should be fine.

How Often Do You Really Have to Wash Your Bedding?

Maintaining a clean and healthy sleeping environment requires regular attention to your bedding. While the frequency of washing various bedding items can differ, a consistent cleaning routine is essential for hygiene and comfort. Here's a breakdown of how often each piece should be washed, the reasons behind it, some tips to keep your bedding fresh and germ-free, and real research to support these practices.

Sheets and Pillowcases

Frequency: Wash sheets and pillowcases at least once a week.

Why: These items are in direct contact with skin and can accumulate sweat, body oils, dead skin cells, and saliva. This creates a breeding ground for dust mites, bacteria, and allergens. Regular washing helps prevent these contaminants from building up, reducing the risk of allergies and skin irritations. According to a study published in the Journal of Allergy and Clinical Immunology, weekly washing of bedding can significantly reduce dust mite populations and allergen levels.

Tips for Washing:

• Hot Water: Use hot water (at least 130°F) to effectively kill dust mites and bacteria. High temperatures ensure that most pathogens and allergens are eliminated.

• Gentle Detergent: Choose a gentle, hypoallergenic detergent like Dropps Sensitive Skin & Baby Detergent Pods or All Free Clear Liquid Detergent to avoid skin irritations. Hypoallergenic detergents reduce the risk of reactions in sensitive skin.

• Avoid Fabric Softeners: They can leave residues that trap more dirt and bacteria. Instead, use white vinegar in the rinse cycle to naturally soften fabrics. White vinegar also helps in breaking down detergent residues.

• Timely Transfer: Don't leave wet items in the washer for more than 4-6 hours to avoid mildew and mold.

Comforters and Duvet Covers

Frequency: Wash comforters every 2-3 months and duvet covers every 2-4 weeks.

Why: Comforters and duvets, though not in direct contact with skin, still gather dust, sweat, and allergens over time. Duvet covers, acting as a barrier, need more frequent washing to protect the comforter. The National Sleep Foundation recommends washing comforters a few times a year to keep them clean and free from allergens.

Tips for Washing:

• Check Labels: Follow the manufacturer’s care instructions. Some comforters may require dry cleaning. Adhering to care labels preserves the integrity and longevity of the bedding.

• Large Capacity Washer: Use a large-capacity washer, such as those found at local laundromats or laundry services, to ensure thorough cleaning. Sufficient space in the washer allows for better agitation and rinsing.

• Mild Detergent: Use a mild detergent, like Seventh Generation Free & Clear, on a gentle cycle. This helps protect the fabric and filling from harsh chemicals.

• Thorough Drying: Dry thoroughly on low heat to prevent mold growth. Adding clean tennis balls or dryer balls helps fluff the filling. Proper drying ensures no residual moisture, which can lead to mold.

Pillows

Frequency: Wash pillows every 3-6 months.

Why: Pillows collect sweat, oils, and dead skin cells, becoming a haven for dust mites and bacteria. Regular washing maintains their cleanliness and prolongs their lifespan. A study from Ohio State University found that up to 10% of the weight of a two-year-old pillow can be composed of dead mites and their droppings.

Tips for Washing:

• Machine Washable: Most synthetic and down pillows can be machine washed. Check the care label first. Ensuring pillows are machine washable makes maintenance easier.

• Gentle Cycle: Use a gentle cycle with a small amount of mild detergent like Tide Free & Gentle. This prevents the filling from clumping and the fabric from tearing.

• Thorough Drying: Dry completely on low heat. Use dryer balls to keep the filling evenly distributed. Thorough drying prevents mildew and ensures the pillow retains its shape.

Mattress Protectors and Toppers

Frequency: Wash mattress protectors and toppers every 1-2 months.

Why: These items shield the mattress from spills, sweat, and allergens but can get dirty themselves. According to the Sleep Foundation, mattress protectors should be washed regularly to maintain their protective qualities.

Tips for Washing:

• Regular Maintenance: Follow care instructions for washing. Most can be machine washed on a gentle cycle with warm water. Regular washing maintains the protector’s effectiveness and hygiene.

• Drying: Air dry or use a low-heat setting in the dryer to avoid damage. Proper drying ensures the material remains intact and free from mold.

• Timely Transfer: Don't leave wet items in the washer for more than 4-6 hours to avoid mildew and mold.

The Dirt and Germs Accumulating in Bedding

Bedding can harbor a variety of unwanted guests, including:

• Dust Mites: These microscopic creatures feed on dead skin cells and thrive in warm, humid environments. They can exacerbate allergies and asthma.

• Bacteria and Viruses: Sweat, body oils, and saliva introduce bacteria and viruses into bedding. These can lead to skin infections and unpleasant odors.

• Fungi and Molds: Moisture from sweat and spills can promote the growth of fungi and molds. This can cause respiratory issues and further allergen exposure.

• Pet Dander: If pets sleep on the bed, their dander and hair accumulate in the bedding. Pet dander can trigger allergic reactions and worsen asthma.

• Environmental Allergens: Pollen, dust, and other allergens settle on bedding, exacerbating allergies. Regular washing removes these allergens, providing relief to those sensitive to them.

Surprising Facts and Best Practices

• Sweat Production: The average person sweats up to one liter per night, much of which is absorbed by the bedding. This moisture can encourage the growth of bacteria and mold.

• Dead Skin Cells: Humans shed about 500 million skin cells per day, many of which end up in the bed. These cells attract dust mites and contribute to allergens in the bedding.

• Allergy Relief: Regular washing of bedding can significantly reduce symptoms for people with allergies or asthma. Clean bedding creates a healthier sleeping environment.

• UV Light: Sunlight can naturally disinfect and freshen bedding. Hanging sheets and pillowcases outside on a sunny day helps eliminate odors and bacteria. UV light kills bacteria and mold, leaving bedding fresher.

Tips for Maintaining Fresh Bedding

• Rotate Bedding: Having multiple sets of sheets and pillowcases allows for regular rotation and ensures a clean set is always available. This extends the life of each set and keeps the bed consistently fresh.

• Use Mattress and Pillow Protectors: These create an additional barrier against dirt and allergens and are easier to wash than the mattress or pillows themselves. Protectors enhance hygiene and reduce the frequency of washing the actual mattress and pillows.

• Regularly Vacuum the Mattress: This helps remove dust and allergens that accumulate over time. Vacuuming can reduce allergens and extend the life of the mattress.

• Air Out Bedding: Regularly airing out comforters, blankets, and pillows helps reduce moisture buildup and keeps them fresh. Airing out bedding prevents musty odors and mold growth.
