At the end of last year I tried one of the latest health trends- Floating! Basically there is a large floating tank (which has the option to close completely)and has about a foot of water and tons of Epsom salts. There’s also a light and relaxing music- both of which you can turn off. This type of sensory deprivation is apparently highly beneficial for relieving depression, anxiety, etc. and helping relaxation.I floated for 30 minutes shortly after the marathon and I definitely think it improved my muscle soreness… it was relaxing but also kind of freakyyyy! I think the first time is a bit of a shock so I would be more likely to get more relaxation going another time.
