Was Grandma Right About Not Sleeping with Wet Hair?

August 06, 2019


Sleeping with wet hair - yay or nay? Here's the gist.

Righto, let’s talk old wives tales. It’s easy to scoff at your grandma when she suggests that eating carrots will improve your nighttime vision, cheese to close to bedtime will give you weird dreams and honey can help to ease a cough (all of these have been proven accurate by the way!). But how about sleeping with wet hair? Do you believe that it will make you ill as our grandmas do? 

The answer to whether or not sleeping with wet hair will make you ill, believe it or not, is no, but also a little bit yes. Let’s explain. 

NO, sleeping with wet hair will not make you sick

According to Dr William Schaffner, the doctor at the helm of the Infectious Diseases department at Vanderbilt University Medical Center, the idea that sleeping with wet hair will make you sick is connected to the notion that being chilled and/or wet is connected to coming down with a cool. This has long since been disproven - being cold does not give you a cold; the common cold is the result of respiratory viruses. 

YES, sleeping with wet hair can cause some other issues

However, sleeping with wet hair can cause some other issues. These include: 

  • Brittle hair with little shine and elasticity. When a hair cuticle is exposed to wet conditions for lengthy periods of time, it can be penetrated, which leads to the rupture of the inner cortex. The result is limp, lifeless hair. (But this can also be rectified with a good conditioner, so it's not such a huge deal.)

  • Skin irritation. If you tend to sleep on your stomach with your head to the side, the friction between the wet hair and the skin of your face could lead to irritation. The evaporating water can also cause dryness of the scalp in the long run. 

  • Smelly pillows. Microorganisms like dust mites, moulds and fungus-like damp environments, so if you make a habit of going to bed with wet tresses your pillows can become a little funky. Wash your pillowcases and sheets in hot water once per week and place the pillow itself in the sun to dry out if you want to keep potential irritants to a minimum.
