If you find it hard to relax on your day off because you can’t stop worrying about the little things, try this: Rub on a little coconut-scented lotion, or light a coconut candle. Research at Columbia University found the aroma of coconut helps blood pressure return to normal after a stressful task. It also reduces the levels of the stress hormone cortisol by 24%. The reason? Because the smell of coconut stimulates the area of the brain that regulates mood.
