How do I avoid myself from cold stuff when the weather is really hot?(For girls only)?

I just hate it whenever I eat or drink cold stuff my stomach would ache real bad when I'm having my period afterwards.And my health teacher told me that females have to stay away from cold foods and beverages but somehow when the temperature gets higher I would always quench myself a cold icy drink from the fridge and then get an upset stomach when I'm having my period.So does anybody know what I could do to stay away from cold stuff even when the weather is so hot?

I don't believe there is ANY relation between cold food, hot weather, stomach aches, and periods. stomach aches and periods, yes, stomach aches and cold food/hot weather? not likely!! how exactly did your health teacher explain this? sounds bizarre.
