In the past few years, self-care has been occasionally and incorrectly equated with self-indulgence. Sure, self-care can mean throwing down for spa treatments, a new wardrobe or fine leather goods, but there are plenty of other ways to "treat yo' self." Some of the most powerful and healthy self-care habits for your mind and body are actually pretty simple, not to mention free (or pretty close to it).

Here are seven surprising self-care habits that will make you glow from the inside out.

Making time for hobbies is crucial to self-care. One surprisingly powerful hobby for stress relief and mental wellness? Knitting. Research shows that doing textile crafts has similar health benefits to meditating, protects against cognitive decline and alleviates symptoms of mental health conditions, like anxiety and depression.

Luxuriating in the tub is a self-care habit we can get behind -- and not just because we love bath bombs. Marinating in hot water has a slew of health benefits comparable to low-impact exercise: It may lower blood pressure, improve circulation, boost immunity and reduces pain and inflammation. Not too bad for something you can do lying down.

Self care doesn't require a huge investment of time; it can be as simple as a snuggle sesh with someone you love. Studies indicate that cuddling with another person or beloved pet lowers blood pressure and cortisol levels. It may also increase oxytocin, a hormone that makes you feel calm, bonded and mentally sharp.

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.
