    Dark and Tight Clothes

    Darker shades have the tendency to absorb more heat, resulting in more perspiration, while tight fitting clothes make it difficult for the body to cool itself down externally, which eventually hinders the internal body temperature. If it is too hot outside, dark and tight clothes can make you perspire enough to cause dehydration. Image Courtesy: Getty

    Stress causes adrenal glands to pump out stress hormones. The same glands also produce the hormone aldosterone, which helps regulate your body's levels of fluid and electrolytes. Due to adrenal fatigue during constant stress, the production of aldosterone drops leading to dehydration and low electrolyte levels. Image Courtesy: Getty
