All of us have heard at some point during our life, especially in younger days, to not go outside with wet hair even in hot summer days.
Usually, this is a sentence addressed by mothers or grandmothers, but, is this true or it’s just a nonsense.
As scientists have discovered, with this habit, or better said, bad habit, we can have serious consequences, starting from terrible headaches to meningitis.
On the other head, if you thought you are protected because your hair is completely dry, keep in mind that although the hair is dry, moisture is retained in the hair follicle. Hours after washing hair, your head pores are open as they absorb water. With this, your immune system is exposed to harmful influences and in this case even the wind can hurt you.
The simplest consequences of going out with wet hair are headaches and colds, sinus inflammation up bigger health issues like facial nerve problems and meningitis.
If you use a dryer, it would be good to stay in a warm (inside) at least 1 hour and if you want your hair to naturally dry, you have to be patient for 5 to 6 hours.
