8 steps to feeling happier, healthier, and less stressed out

Stress becomes a problem when our body's "stress response is activated for a prolonged period of time, without the body's returning to its relaxed state." Therefore, it's important to figure out ways to deal with stress.

Scott suggests trying relaxation breathing, in which you simply find a quiet place to sit and focus on your breathing for a while. "The act of consciously releasing the tension in the body and forcing our breathing to mimic the more relaxed breathing that our body enacts at a resting state can help to reverse the body's triggered stress response and thus help to physically relax," she writes.

Living a healthy lifestyle is critical for both your physical and mental health. Maintaining healthy eating, exercise, and sleep habits makes a huge difference.

Even small improvements to your diet, workout routine, or sleep schedule can make a big difference, Scott writes, in the sense that habits work off of each other and "one change makes all the other changes come more easily."

"We can control our responses to circumstances, even when the circumstances themselves are beyond our control," Scott writes. "In doing so, we can greatly lessen our negative experience of stress."

It's all about having a positive attitude. For example, it's better to avoid the all-or-nothing mindset: Rather than say, "This is the worst day ever," say, "Today was a bad day," she advises.

Put systems in place to minimize stress, Scott says. "In virtually all areas of life, it helps to plan ahead — and these plans need not be complicated," she writes.

Keep your desk orderly, use to-do lists, and be proactive about starting challenging projects early. Use your lunch break to de-stress by taking a brisk walk, meditating, and reflecting on the things you're grateful for.

"Most of us know at least one person who takes the wind out of our sails," Scott writes. These toxic people, generally described as critical, unfriendly, judgmental, and filled with complaints, can bring you down with them.

Toxic relationships are one of the biggest stressors, she says. That's why it's important to identify this person(s) and establish boundaries. "Don't allow yourself to be sucked in. You can be polite, and still simply avoid them as much as possible, and cut out the stress they bring as a result," she writes.

"This relatively new field centers on studying what makes us healthy and happy, rather than looking at factors that contribute to pathology and disease," Scott writes.

Start by identifying which areas of your life could improve and which areas bring you the most joy. This can help you figure out if you have enough balance and what you need to better incorporate into your life.

Scott lists meditation, exercise, and journaling as three of the best habits for building resilience. The stress-relieving benefits that come with these are accumulated over time and can have a significant long-term impact, Scott writes.
