Sleep is an essential human function. Modern day society has made it so that sleep is prioritized less and less. Professionals in critical positions such as doctors, nurses, and emergency medical technicians can often have hectic schedules that are unforgiving toward sleep due to the increase in shift work that dominates these fields. Sleep deficits can have detrimental effects on one’s psyche and mood. Depression and anxiety both have high comorbidity rates with insomnia because of sleeping deficits. Transdermal Electrical Nerve Stimulation (TENS) offers a potential solution to improving sleep quality and mood by modulating the ascending reticular activating system (RAS). This system starts in the anterior portion of the head with trigeminal nerve branches and is stimulated using a 500-550 Hz waveform.

In this experiment Positive Affect and Negative Affect Schedule (PANAS) scores are recorded daily to monitor mood differences between pre and post treatment (TENS vs Sham). PANAS scores were found to be insignificant between groups. Pittsburgh Sleep Quality Index (PSQI), and Fitbit were chosen to study perceived sleep, and objective sleep. Both PSQI, and Fitbit found insignificant differences between TENS and Sham. Finally, the Beck Depression and Beck Anxiety Inventories were administered weekly to determine if there are immediate changes to depressive and anxiety symptom, after a week of treatment (TENS vs Sham). A significant difference was found between the pre and post of the TENS treatment group. The TENS group was not found to be significantly different from Sham, potentially the result of a placebo effect. These results were found with n=10 participants in the TENS treatment group and n=6 in the sham group.

The various health benefits of vinegar ingestion have been studied extensively in the<br/>literature. Moreover, emerging research suggests vinegar may also have an effect on mental<br/>health. Beneficial effects of certain diets on mood have been reported, however, the mechanisms<br/>are unknown. The current study aimed to determine if vinegar ingestion positively affects mood<br/>state in healthy young adults. This was a randomized, single blinded controlled trial consisting of<br/>25 subjects. Participants were randomly assigned to either the vinegar group (consumed 2<br/>tablespoons of liquid vinegar diluted in one cup water twice daily with meals) or the control<br/>group (consumed one vinegar pill daily with a meal), and the intervention lasted 4 weeks.<br/>Subjects completed mood questionnaires pre- and post-intervention. Results showed a significant<br/>improvement in CES-D and POMS-Depression scores for the vinegar group compared to the<br/>control. This study suggests that vinegar ingestion may improve depressive symptoms in healthy<br/>young adults.
