Due to their extremely high 96% water content and tough protective skin, the inside temperature of cucumbers can be up to 20 degrees cooler than the outside air, making them an ultra-refreshing, low-calorie option when the mercury starts to rise. By that same logic, you know cucumbers will keep their cool for beach trips and picnics. Plus, they’re slim-sational: A whole entire cucumber has just 45 calories. BONUS! You can even peel off strips of a chilled cucumber skin and place them across your forehead when you need a little extra relief (heads up, you can capture some hilarious photos of friends and relatives sporting these cucumber “masks”!). Get a double dose of cucumber by dunking thin slices into my Cuke-A-Licious Yogurt Dip!
