If you have trouble getting cool in summer or if you sweat a lot during exercise, try using sandalwood oil as a splash on cologne. Sandalwood oil has cooling properties and is used in many Asian countries to cool the body when no air conditioning is available. It smells great and works as a natural coolant on the skin. It’s also great for acne, eczema and other skin problems that can be caused by sensitivity to heat. Regrettably, due to over cultivation in India, it's very difficult to find good quality sandalwood oil, unless you happen to visit the Mysore Provence in India or Dubai- where they sell all sorts of essential oils and fragrances.. Still, even diluted versions that can be found in the USA work pretty well to keep you cool in summer months. Try shops that sell incense or Indian goods, and if possible purchase the Mysore brand which regulated by the Indian Government and is the most pure oil available in most cases.
