The harmattan season usually make some people perform below expectation as it is always accompanied with cold,cattarh and the likes.
However,to start the day,bathing is always a ardous task for some people. some even find it difficult to bath with ordinary water as they will go any lenght to have it boiled . I too has found it difficult to bath very early in the morning in time past;as i will always bath in the evening or afternoon when the cold is not as much as it was in the morning.
Now,i have a work!!! i can no longer wait till evening to have my bath,so i deviced a method of bathing.
when bathing with ordinary water
i make sure i start by washing my feet thouroughly up to my waist then,after that,i wash my face and followed by other parts of the body.
This,i have been trying for a very longtime now and it saves me time,lessen the cold and cool!
when bathing with warm water
i can assure you that you'll have much cold than the person who bath with only ordinary water.
This might help although,not yet proven by anyone except me.
This is a research made by my humble self as any anyone who wishes to try it out should take precaution because i will not be reponsible for any aftermath effect.

exactly!!! start from your feet up. and if you must use hot water, to prevent/reduce the after chills wipe every drop of water from your body immediately.
