Hello, I have gone through your query and understood the concern. Hot flashes can still happen at your age and several things could be causing them. Hormone imbalance caused by the hypothalamus, hypothyroid state, recent medications or vitamin supplements, hot weather, hot surroundings, infections and so on. While you can try some remedies like using plenty of fresh fruit and vegetables, using loose fitting cotton wear, meditation and breathing exercises apart from maintaining comfortable surroundings, it is always better to have a proper clinical opinion. Hope this helps.
