Pitso:
The cold/hot shower routine works great for circulation. That's why all those happy Canadians are always jumping out of the sauna into a snow bank! You can also just do your feet in a bucket of ice water and then hot water (not burning) as this really gets your circulation and immune system energized.
Depression like cancer hates light, energy, movement, wind, heat, circulation and happiness/smiles.
As Mayflower said stay away from water 30 minutes before and 30 minutes after SFQ active exercises or meditations. Never meditate in water as it just drains away your energy.
Depression is a lung channel problem so you want to really smile and open your lung channel, pat your arms and spend some extra time visualizing clean energy coming into your lungs and all those blockages coming out like diesel soot out of an old ford flatbed truck. Spend a little extra time doing the SFQ level 1 exercises that focus on the lungs.
Spiritual people are more sensitive to the environment, people and other influences so you do have to take a look at what is going on around you as well.
Let us know how you are doing. By developing your spiritual energy you will overpower these pesky physical body problems. It will be like cutting butter with a chainsaw,
