If the family is feeling stressed, moody or a bit low one way to lift your mood, even if it’s only a short term boost, is to change your environment.
Why not go for a walk in the natural world. Get out into the countryside, go to the beach, or even just your local park or gardens. Connect with mother nature, feel the sunshine on your face and get some of that natural vitamin D. Studies have found that getting outdoors in your natural environment has an immediately relaxing effect on the brain.
Other short term strategies for changing your environment could also involve cleaning up and organising the house, maybe even a de-clutter, or getting out and about and going somewhere different.
These may only be short term strategies and may not have long lasting effects, but it can give you an instant boost. To help you snap you out of your anxiety long enough to get going on something that will have longer term impact on your mood.
