A Promising Alternative to Medication: FIR-Emitting Pajamas for Poor Sleepers

by


Clinical trial shows that FIR-emitting pajamas can provide an alternative to medication for poor sleepers

Sleep difficulties are common and affect many people worldwide, causing daytime consequences such as fatigue and impaired functioning. Optimizing the sleep environment, including clothing, may help alleviate sleep problems. Far infrared (FIR)-based textiles have been shown to promote blood circulation and improve metabolic function, making them a potential therapeutic alternative for poor sleepers.

Clinical Trial

In a pilot study, researchers investigated the effects of FIR-emitting pajamas on sleep quality in adults with poor sleep quality. The study was a randomized, sham-controlled trial that included forty subjects randomized to FIR-emitting or sham pajamas in a 1:1 ratio. The primary outcome measure was the Pittsburgh Sleep Quality Index (PSQI). Other measures included the Insomnia Severity Index, a 7-day sleep diary, the Multidimensional Fatigue Inventory (MFI), the Hospital Anxiety and Depression Scale, the Epworth Sleepiness Scale, and the Satisfaction with Life Scale. The outcomes were measured at baseline and weeks 2, 4, and 6.

Results

Both groups showed improvements in the PSQI score within their groups, indicating that both FIR-emitting and sham pajamas positively affected sleep quality. However, there was no significant difference between the two groups. Interestingly, FIR-emitting pajamas performed better than sham pajamas in reducing the MFI-physical score. This finding suggests that FIR-emitting pajamas may improve physical fatigue in adults with poor sleep quality. Additionally, the intervention compliance was satisfactory, indicating that participants could use the FIR-emitting pajamas as instructed.

Conclusion

While FIR-emitting pajamas may not be superior to traditional pajamas in improving sleep quality, they may reduce physical fatigue in adults with poor sleep quality. This pilot study provides preliminary evidence that warrants further exploration in more extensive and diverse populations. It is essential to continue exploring non-pharmacological interventions such as FIR-emitting pajamas to help individuals with sleep disturbances improve their overall well-being.
