Sweat rate and sweat electrolyte loss were studied in 32 male Nigerians. Each subject was studied thrice at room temperature (RT) of 270C+20C and a relative humidity (RH) of 70+5%; at 370C and RH 90+5%; and during exercise at
RT0C+20C and RH 70 %. Sweat was collected simultaneously from the forehead and forearm using the filter paper disc technique.

Since calcium and magnesium are essential to the body’s needs, their input and output are generally balanced by their dietary intake and their loss through the excretory organs. This study investigated the concentrations of calcium and magnesium in the sweat excreted from normal Nigerian men sweating under raised temperature or during exercise heat and exercise conditions.

Numerous international studies have indicated that several physiological changes can influence the intraocular pressure (IOP) of subjects. In order to assess visual health status through physiological changes, the effects of rest and exercise on IOP were investigated in a Nigeria community. The research involved 24 healthy normotensive subjects who were made to serve as their own control.
