3. Synthetic fabrics

Similar to heavy clothes, synthetic fabrics such as nylon or polyester can also disrupt your body’s temperature. “These fabrics can cause discomfort while sleeping since they don’t allow your skin to breathe, trapping body heat and leading to overheating during the night,” says Oliver.

Apart from ruining your sleep, synthetic fabrics can also cause health problems. As detailed by Chris McDermott, an advanced practice registered nurse (APRN) at Intercoastal Consulting & Life Care Planning, such clothing “can trap heat and moisture, which can lead to skin irritation and fungal infections.”

Jeff Kahn, co-founder and CEO at Rise Science cautions against using sleepwear or bedding made of microfiber, which in reality is another name for polyester. To improve the quality of sleep and your sleeping environment, opt for natural fabrics such as linen, bamboo and cotton. These fabrics are cool and comfortable, perfect for a good night’s sleep.
