Research has shown that a literal day of "REST" that is, restricted environmental stimulation therapy can work wonders. After a day of quiet on a comfortable bed in a dark, soundproofed room, people often emerge refreshed and with new self-control - an improved ability to stop smoking, to reduce drinking, to lose weight. Smaller doses of solitude even a daily few minutes of meditation or prayer, can provide spiritual recharging for active living.
