Meditation: Sitting and focusing even for a short amount of time can cause the reduction of stress in the body. Meditation doesn't have to be done sitting still. There are many forms of movement meditations from dance to yoga that can allow even the biggest skeptics to feel the benefits. Try sitting for 3 min focusing on your breathing pattern. Don't change the pattern just be aware of it. The moment you notice your mind wandering off just gently remind yourself to watch the breath again.
Breathing: Deep breathing can help you access your parasympathetic nervous system. It calms the body and helps activate the relaxation response allowing you to feel less agitated and more relaxed. Try it. Set a timer for two minutes, sit up tall. Try and breath in and out through your nose. Try lengthening the exhale to be two parts longer than your inhale. Make the breath easy and repeatable. Notice how you feel.
Exercise: Exercise lowers the stress hormone in the body cortisol. It also helps release endorphins which help improve your overall mood and mindset. Try it get up go for a 5 min walk around the block. Do some jumping jacks or a few pushups. Make more movement part of your day by building it in. I like to do this by walking my kids to school or parking the furthest from the store rather than the closest.
Thai Massage: Thai Massage is a fantastic way to lower your current stress levels. There's nothing quite like being cared for by another human being to help us relax and take the edge off. Physical touch has been found not only to be necessary in our development but also in helping us manage and relieve tension levels in our bodies.
