A common health myth shared by many social media users claims that keeping hair wet after bathing will cause a cold. We fact-checked and found that the claim is False.
A lot of people believe and share on social media that if you keep your hair wet you will catch a cold. Such posts can be seen here and here.
Can you catch cold if you keep your hair wet?
No. The common cold is caused by viruses. Keeping the hair wet, being in cool temperature with wet hair, sleeping with wet hair – all these will not cause a common cold. This is an old myth that has been debunked by medical professionals for years.
Dr. Deepanshu Khanna, MBBS, MD, DNB(General medicine) says, “These beliefs are all misconceptions. Although these beliefs are amongst us for ages, there is still no scientific basis behind these beliefs. The cause of fever or a cold is infectious virus or bacteria, and also dust in the wind which causes allergy-related issues.”
Dr. Khanna explains further, “You may catch a cold if you eat something unhygienic, without washing your hands or from eating something that causes allergic reactions in your body. But showering with cold water or wet hair after a shower is not the cause of catching a cold or fever. In fact, showering with cold water has some health benefits. It increases blood circulation, improves metabolism, can help reduce inflammation or deal with depression.”
That said, there is one isolated research that showed keeping the feet in chilled water for a long duration became more susceptible to catching a cold. Note, the research did not have anything to do with wet hair but just experimented with wet feet. Also, only 10% of the small group who participated in the research caught cold. and the researchers concluded, “Further studies are needed.”
Is it ok to sleep with wet hair?
Not exactly. Though you will not catch a cold, there can be other health issues arising due to wet hair. These can include hair damage and fungal infections including dandruff.
