Whether or not you're feeling under the weather; aches and pains, mental and/or physical, if you have a bath/shower apparatus, I beseech thee to try this:
Take a warm shower for a few minutes and then turn it over to a warm bath throwing in some bath salts and/or oils and soak in that for five times as long.
Then, once you've soaked and relaxed drain the bath, but simply lay in the water and feel as the level lowers slowly around you and pulls away all that negativity.
But, then, turn it back over to a cool shower, rinsing off the salts and oils and residual bath debris, and slowly increase the temperature, for it shall impart an appreciation for what you have.
Then, allow yourself to air-dry and do some light stretching. I think you may find, as I sure have, that this is a great way to reset the body and mind.
Even burn some incense and/or candles and put on some music, or just let the music of the sounds and feelings play for thee a symphony.
