- Brief Summary
The objective of this research study is to assess how the implementation of various modern strategies for augmented recovery affect sleep quality, subjective wellness and other indices of general well-being.
- Detailed Description
Traditional flotation therapy (Float-REST; Flotation Restricted Environmental Stimulation Therapy) uses sensory deprivation tanks that consist of a very large warm water enclosure with a high concentration of Epsom salt to create a completely buoyant environment. This, along with a combination of temperature that is kept equal to skin temperature (94 degrees), allows the participant to eliminate the gravitational effects on the body, and along with lack of sound and low to no light (depending on comfort) allows the brain and body to completely relax for augmented physical and mental recovery. Provided the growing understanding that sleep quality and quantity are at the forefront of ensuring optimal human performance states, compounded by the deleterious effects of high stress and anxiety on sleep, utilizing flotation therapy as a mechanism for enhancing sleep requires further investigation. In addition to the traditional Float- REST, there have been developments in newer technologies that enhance the convenience of receiving these proposed benefits; Zerobody Dry Float technology (www.Zerobody.com) rids the need for multiple showers by its user, frequent water treatments, and extensive maintenance experienced with traditional flotation environments. However, research is still needed to assess how this recovery modality compares to traditional Float-REST.
To assess whether traditional (Float-REST) or simulated (Dry Float) flotation therapy positively influences sleep and perceptual recovery, participants will undergo a crossover study. Over the course of 9 weeks, participants will alternate Float-REST and Dry Float in 3 week segments with a 1 week break in-between to gather baseline data (known as the testing battery). In addition, testing battery data will be collected at weeks 1 and 9. The order in which participants begin their crossover study, either Float-REST or Dry Float, will be randomly assigned. All participants may wear a fitness tracker and a sleep monitoring ring worn on the finger for the duration of the study. In addition, daily, per session, and pre/post-study questionnaires will be submitted via a smartphone application.

- Primary Outcome Measures
Name Time Method Change in per session self-report measures 2 times a week, in 3 week increments, through study completion at 9 weeks State-Trait Anxiety Index (STAI) - Commonly used measure of state and trait anxiety, and done with 20 very brief questions. Values range from 20 to 80, with higher scores representing more severe anxiety. Participants will complete the STAI questionnaire before and after each session, twice a week. The sessions will take place during weeks 2-4 and weeks 6-8.
Change in qEEG assessment measures Week 1, week 5, and week 9 The following assessments are used to determine central nervous system function and overall brain health:
Symptom checklist-150 brief questions; ranking your propensity for traits on 1-7 scale.
qEEG/ERP assessment-determine central nervous system functional integrity and overall brain health. First half of the assessment will consist of recording two segments in both the eyes-closed and eyes-open condition. Next segment is completed in a series of three sequential measurements, of a bilateral pair of EEG channels. Finally, a 10-minute active auditory task.Change in testing battery self-report measures in emotional regulation Week 1, week 5, and week 9 Emotion Regulation Questionnaire (ERQ)-10-item scale designed to measure tendency to regulate emotions. Each item is answered on a 7-point Likert Scale (1=strongly disagree to 7=strongly agree). Higher scores indicate a higher emotion regulation strategy.
Change in sleep patterns as measured by OURA ring Daily from baseline through study completion at 9 weeks Oura Ring is a connected health device worn on the finger that measures sleep. Sleep summaries per day will be compared.
Change in daily self-report measures for task load Daily from baseline through study completion at 9 weeks End of Day Questionnaire (EoD)-Developed at the Rockefeller Neuroscience Institute (RNI) as a modification of the NASA Task Load Index. There are 5 Likert scales to assess workload (0=very low and 100=very high), as well as 4 follow up questions. This questionnaire addresses subjective measures of workload and stressors that were encountered throughout the day.
Change in daily self-report measures in perceived exertion Daily from baseline through study completion at 9 weeks Post-Training Rating of Perceived Exertion Questionnaire (Post-Training RPE)- An adaption of the Borg Rating of Perceived Exertion scale, commonly referred to as RPE. The questionnaire requires participants to list the specific activity and the subjective measure of exercise intensity. The scale ranges from 6-20 (6=no exertion that is equivalent to rest and 20=maximal exertion). This questionnaire logs activity (i.e. workout, walk, run, hike) and address subjective exertion levels encountered exercise based activities throughout the day.
Change in testing battery self-report measures in mindfulness Week 1, week 5, and week 9 Five Facet Mindfulness Questionnaire (FFMQ)-39 item inventory assesses the five facets of mindfulness on a 5-point Likert Scale (1=never or very rarely true and 5=very often or always true). Each facet is tallied and the sum total responses are divided by 39 (number of items). Higher scores indicate higher levels of mindfulness.
Change in testing battery self-report measures in sleep quality Week 1, week 5, and week 9 Pittsburgh Sleep Quality Index (PSQI)- 19 item inventory with 7 subjective components that assess sleep quality over time. Each component is scored from 0 to 3 (0=very good and 3=very bad). The sum of the components is the global score and ranges 0-21 (0=no difficulty and 21=severe difficulties). The higher the global score, the poorer the sleep quality.
Change in daily self-report measures for recovery Daily from baseline through study completion at 9 weeks Short Recovery and Stress Scale (SRSS)-An 8 item inventory that assess subjective measures of physical, mental, and emotional recovery on a 7 point Likert Scale (0=does not apply at all to 6=fully applies). High values in overall recovery indicate feeling physically and mentally recovered. High values in overall stress indicate feeling overloaded and physically tired. This questionnaire addresses subjective measure of readiness for the day ahead.
Change in testing battery self-report measures in personality Week 1, week 5, and week 9 Big Five Inventory (BFI)-44 item inventory designed to measure the Big Five Factors of personality on a 5-point Likert Scale. Higher scores indicate a higher tendency for that personality trait (1=disagree strongly to 5=agree strongly).
Change in testing battery self-report measures for recovery Week 1, week 5, and week 9 Acute Recovery and Stress Scale (ARSS)- A 32 item inventory that assess subjective measures of physical, mental, and emotional recovery on a 7 point Likert Scale (0=does not apply at all to 6=fully applies). High values in overall recovery indicate feeling physically and mentally recovered. High values in overall stress indicate feeling overloaded and physically tired.
State-Trait Anxiety Index (STAI)-20 item inventory assesses state and trait anxiety. Values range from 20 to 80, with higher scores representing more severe anxiety.Change in qEEG questionnaire measures Week 1, week 5, and week 9 PERMA-Profiler-measures five pillars: positive emotion, engagement, relationships, meaning, and accomplishment. The measure consists of 23 items rated on an 11-point Likert scale (0= never/not at all; 10= always/completely.
Change in testing battery self-report measures for anxiety Week 1, week 5, and week 9 State-Trait Anxiety Index (STAI)-20 item inventory assesses state and trait anxiety. Values range from 20 to 80, with higher scores representing more severe anxiety.
Change in qEEG questionnaire measures for stress Week 1, week 5, and week 9 Holmes \& Rahe Life Stress Inventory- measures amount of stress an individual has experienced within the past year. This scale serves as a control variable; the endorsed events are influencing the individual's current mood, emotions, etc. and in turn their brain function. 43 brief, yes-or-no-type questions.
