You have just treated yourself with a massage and you are feeling relaxed and your muscles are feeling looser. Your massage therapist's job is done for now, but it's time for you to act to prolong the benefits of your treatment.
Drink (A LOT OF) water
Water helps kidneys to flush out toxins released during your treatment, and to re-hydrate your body and muscles. This can also help to reduce muscle aches following the massage.
Take a bath (fancy name for this is a hydrotherapy)
Warm water is very soothing after massage, especially with Epsom Salt (Magnesium Sulphate) as it is a natural muscle relaxant.
Do stretches
Stretching helps to keep your muscle fibres lengthened and more flexible much longer after your massage. It also increases blood flow to your muscles, which will aid healing.
Rest
Don't plan any strenuous activities for the rest of the day. You may feel tired after your treatment and that is very normal. Take a nap, and give your mind and body a chance to rebalance.
Pay attention to your body's reactions
You may feel a bit sore and groggy, especially after a deep tissue massage. This is something called "Post-massage soreness and malaise" or a "healing crisis". A healing crisis is probably more commonly used term for it. Also, using a toilet more frequently is completely normal. These are signs of your liver and kidneys working hard to remove released waste products from your body.
