"No matter the cold, I can't bathe in warm water.

This is me and I do tell people that what will make me bathe in warm water would be that I am sick. I don't like taking warm water but cold no matter how cold the weather is. I don't use sweater either but when I couldn't cope with how the cold is severe here, no one told me to go look for my sweater where it has been kept without touching it. In fact, during harmattan period, I will still put on the fan, hahaha
Your story is right that we may not experience any side effect now but the little damages it is causing in our internal system is something we should be careful of.

I wish I could change to using warm water but where is the light to heat water? I can't waste my gas daily for this. May God help us.
