Stress-eating isn't always a bad thing -- especially if your comfort food of choice has heat. Eating something spicy tricks your body into thinking it's being exposed to a high temperature, triggering the release of endorphins, the hormones that make you feel naturally giddy. If it's a food with capsaicin, the chemical found in hot peppers, even better. Capsaicin has natural antibacterial and antioxidant properties.

You knew an exercise tip was coming, and it's true: Working out is a fantastic self-care habit. But you don't need to do a hardcore fitness routine to reap mind-body benefits; just 20 to 30 minutes of walking per day can add seven years to your lifespan, and regular walkers have a lower risk of heart disease than runners. Walking also may boost self-esteem and ease the symptoms of anxiety and depression.
