- New light-and-sound machines are designed to reduce anxiety
-
-
- As recorded birdcalls and musty incense fill the air, half
- a dozen customers file into a tiny office in Manhattan's SoHo
- district. Soon they slip off their shoes, climb into beds and
- lie with eyes closed for the next 45 minutes. Spinning patterns
- of intense colors appear before their eyes, and a low pulsating
- beat follows them as they drift in and out of dreamlike states.
- After the session, a young man rises, looking dazed. "Welcome
- home," a woman says to him. "That was a nice one," he answers
- contentedly.
-
- Was this a mind-expanding drug trip? A cult happening? The
- exercises mandated by an Indian guru? Not at all. The men and
- women at the Synchro Energize salon were engaged in a serious
- stress-reduction exercise, seeking to find greater serenity by
- donning special goggles that flash lights in the eyes and
- headphones that play tones and songs. This high-tech route to
- relaxation may sound far out, but it is starting to catch on.
- About a dozen stress-reduction salons have recently opened in
- the U.S., and they are beginning to spring up in machine-minded
- Japan.
-
- Not just a lure for aging hippies, the centers have
- attracted everyone from harried executives to anxious teens. The
- typical cost: $20 for a 45-minute session. While skeptics
- dismiss the machines as faddish electronic tranquilizers, many
- users swear by the technology's ability to ease stress. Several
- companies have brought out home models of stress-reduction
- units, costing from $99 to $600. Many sets include earphones,
- dark glasses with tiny bulbs inside and a computerized box that
- controls light-and-sound sequences.
-
- The gadgets are an offshoot of serious medical research into
- how visual and auditory stimuli can affect the brain. As it
- functions, the brain emits energy waves in four frequency ranges
- called wave states: beta, which is the normal, alert state;
- alpha, a slower pace noted when people are relaxed and creative;
- theta, the level just before people doze off, when intense
- learning can occur; and delta, which is deep sleep.
-
- Medical scientists have discovered that flashing pulses of
- pure, white light at closed eyes causes patients to see
- kaleidoscopic images. They also noted that by controlling
- patterns of audio and visual pulses, they could cause the brain
- to change states. Researchers like Thomas Budzynski of the St.
- Luke Medical Center in Bellevue, Wash., learned that inducing
- an alpha state could help relax patients and ease chronic pain.
- Creating theta states helped people to improve motivation and
- even stop smoking.
-
- In the commercial arena, manufacturers are claiming the
- machines can boost memory, job and even sports performance. Says
- W.A. Robinson, whose company sells a home model called
- InnerQuest: "If you're going to be competitive in a competitive
- society, you're going to need it."
-
- Or it could be just another fleeting relaxation craze that
- attracts the curious and eventually bores them, like the
- flotation-tank phenomenon of the early 1980s. Not everyone likes
- the sensations the new stress-reduction machines produce.
- Complained a visitor to a Japanese salon: "It's like listening
- to an alarm clock all the time." Nonetheless, in this fast-paced
- era, professionals may turn on to new ways of combating stress
- -- especially since the habit will not show up in random drug
- tests.
