Daily relaxation response breaks in a working population: I. Effects on self-reported measures of health, performance, and well-being.

An experiment conducted at the corporate offices of a manufacturing firm investigated the effects of daily relaxation breaks on five self-reported measures of health, performance, and well-being. For 12 weeks, 126 volunteers filled out daily records and reported bi-weekly for additional measurements. After four weeks of baseline monitoring, they were divided randomly into three groups: Group A was taught a technique for producing the relaxation response; Group B was instructed to sit quiety; Group C received no instructions. Groups A and B were asked to take two 15-minute relaxation breaks daily. After an eight-week experimental period, the greatest mean improvements on every index occurred in Group A; the least improvements occurred in Group C; Group B was intermediate. Differences between the mean changes in Groups A vs C reached statistical significance (p < 0.05) on four of the five indices: Symptoms, Illness Days, Performance, and Sociability-Satisfaction. Improvements on the Happiness-Unhappiness Index were not significantly different among the three groups. The relationship between amount of change and rate of practicing the relaxation response was different for the different indices. While less than three practice periods per week produced little change on any index, two daily sessions appeared to be more practice than was necessary for many individuals to achieve positive changes. Somatic symptoms and performance responded with less practice of the relaxation response than did behavioral symptoms and measures of well-being. (Am. J. Public Health 67:946-953,1977)

Daily relaxation response breaks in a working population: II. Effects on blood pressure.

A 12-week randomized experiment investigated the effects of daily relaxation breaks on office workers with "normal" blood pressure. Blood pressures of 126 volunteers from the corporate offices of a manufacturing firm were measured biweekly. After four weeks of baseline monitoring,volunteers were divided randomly into three groups: Group A was taught a technique for producing the relaxation response; Group B was "taught" to sit quietly; and Group C was taught nothing. Groups A and B were asked to take two 15-minute relaxation breaks daily. During the baseline period, mean systolic blood pressures (SBP) were 119.7, 118.4, and 114.2 for Groups A, B and C respectively; mean diastolic pressures (DBP) were 78.7 and 75.7 Between the first and last measurements, mean changes in SBP were -11.6, -6.5, and +0.4 mm Hg in Groups A, B, and C; mean DBP decreased by 7.9, 3.1, and 0.3. Between the fourweek baseline period and last four weeks of the experimental period, mean SBP and DBP, mean changes in Group A were significantly greater than those in Group B (p < 0.05) and in Group C (p < 0.001). The same pattern of changes among the three groups was exhibited by both sexes, all ages, and at all initial levels of blood pressure. However, in general, within Group A, the higher the initial blood pressure, the greater the decrease. (Am. J. Public Health 67;954-959, 1977)

Patient education and intrauterine contraception: a study of two package inserts.

In July 1975 the Food and Drug Administration proposed a patient information package insert for all women considering use of an intrauterine device. In the same year we also prepared a brochure to be given to women considering use of a specific intrauterine contraceptive, the PROGESTASERT system. To compare these information sources for the patient, we surveyed by mail 253 women who are or had been PROGESTASERT system users. Each woman received either the FDA or our own prepared version. Comprehension of the two inserts was generally comparable, but readers of our insert found its informational content more complete. The survey findings affirmed the desirability of providing the patient with an educational brochure to be read prior to IUD insertion.

Decreased premature ventricular contractions through use of the relaxation response in patients with stable ischaemic heart-disease.

To determine whether decreased sympathetic-nervous-system activity achieved by the relaxation response could decrease premature ventricular contractions (P.V.C.s), eleven ambulatory patients with proven, stable ischaemic heart-disease and P.V.C.s were investigated. The patients, who were taking no medication for the P.V.C.s, were trained to elicit regularly the relaxation response through a non-cultic psychological technique. The frequency of the P.V.C.s was measured by computer analysis of Holter monitor tapes for 2 complete days before learning the technique, which was learned in approximately 5 minutes after the second day. Patients were instructed to evoke the response for 20 minutes twice daily thereafter. After 4 weeks, a reduced frequency of P.V.C.s was documented in eight of the eleven patients. This effect was especially striking during the sleeping hours and less so during the entire monitoring session. The relaxation response is a simple, no cost, non-pharmacological mechanism without side-effects which seemed to decrease the frequency of P.C.V.s in most patients with ischaemic heart-disease.

Continuous measurement of O2 consumption and CO2 elimination during a wakeful hypometabolic state.

A previous investigation has demonstrated that the practice of a meditational technique elicits a wakeful, hypometabolic state. Measurement of O2 consumption and CO2 elimination was made by sampling techniques; mean values of these parameters were calculated from 6-10 minute samples. The present study extends this investigation, using a recently developed method of continuous measurement of O2 consumption and CO2 elimination. Continuous measurement of these parameters permitted the determination of mean values for the entire experimental periods as well as for selected intervals and permitted the examination of the sequence of respiratory changes. The present study reports statistically significant decreases in O2 consumption of 5 per cent and CO2 elimination of 6 percent for the entire 20 minutes of the mediation period. These are lower than the sample values of 16 percent and 15 percent reported in the previous study. However, when selected intervals of the mediation period are examined, decreases in O2 consumption and CO2 elimination are comparable to those previously reported. The results are consistent with the difference between the discontinuous sampling measurement method originally employed and the continuous measurement method of the present investigation.

The relaxation response: psychophysiologic aspects and clinical applications.

It is hypothesized that situations requiring continous behavioral adjustment activate an integrated, hypothalamic response, the emergency reaction. The frequent elicitation of the physiologic changes associated with the emergency reaction has been implicated in the development of diseases such as hypertension. Prevention and treatment of these diseases may be through the use of the relaxation response, an integrated hypothalamic response whose physiologic changes appear to be the counterpart of the emergency reaction. This article describes the basic elements of techniques which elicit the relaxation response and discusses the results of clinical investigations which employ the relaxation response as a therapeutic intervention.
