The aim of the study was to determine whether there is a significant relationship between daily habits such as consumption of tobacco and physical activity, with the number of potential colds over the last year.

For this, we used as research subjects a random sample of 30 individuals representing the class from the 1st year of Nursing Degree from School of Nursing La Fe (Valencia). We conducted a descriptive-correlational study, using discrete quantitative and qualitative variables. From the results, it can be stated that there is no relationship between the variables.

The X2 test between colds and consumption of tobacco obtained a value of 0.8145 which is included in the confidence interval [0 to 7.8147]. In the case of exercise and number of colds suffered throughout the year, we get a X2 of 1.2773 in the same range.

In model F all results are achieved with a value less than 1, 0.032 as the relationship between colds and smoking, 0.12 between colds and exercise and 0.33 in the case of colds and gender. So we can say that the relationships are not significant.

In conclusion we confirm that, for students aged between 18 and 21 years, habits, such as smoking and physical exercise, do not affect the prevalence of colds with a significance level of 95%. However, the results seem to point that this is not a representative sample of age to verify our hypothesis.
