Several times in a row, the thermometer in Austria is now expected to climb well above 30 degrees Celsius and even reach a peak of 37 degrees Celsius. This means that temperatures will no longer drop below 20 degrees at night. The consequence: In the bedroom, the air stands, and the body sticks from the sweat. Summer nights become torture, to say the least, and it worsens.
In the already “cozy” warm bed, we lose an average of 1.5 litres of sweat during sleep. This warm and humid climate provides an ideal breeding ground for bacteria, fungi and mites. High time to change the bed linen! But how often?
Philip Tierno, a microbiologist at New York University, has studied and analyzed our sleep patterns. The scientist revealed to the Yahoo! portal how often we must change our bed linen to avoid sleeping in a pool of bacteria, sweat and dust mites.
The conclusion: our bed must be freshly made once a week! The recommendation says those who sleep without pyjamas and naked should do this even more often, especially in summer.
However, the pillow is excluded from this rule. That should be covered in particularly sweaty nights, even every two days again—a worthwhile effort, because the sensitive facial skin is constantly in direct contact with the pillow. In addition, the nearby scalp is an extreme carrier of bacteria. All of this can lead to skin irritation and blemishes like pimples.
To make sweaty bed covers fresh and hygienically clean again, bed linen should always be washed at 60 degrees. Although 40 degrees is often sufficient, mites are only killed at a washing temperature of 60 degrees.
