Medical and psychological insights influence design:

Sensory Engineering: Weighted nightshirts (containing microglass beads) mimic therapeutic blankets to alleviate anxiety, while brushed fleece linings trigger oxytocin release through tactile stimulation.

Chromotherapy Integration: NASA-developed light-responsive fabrics in hues like “sleep-inducing indigo” and “energizing coral” sync with circadian rhythms via smartphone apps.

Aromatherapy Enhancements: Microcapsules in robe fibers release lavender or bergamot scents when warmed by body heat, lasting up to 30 washes.

Posture Support: Orthopedic-approved nightgowns with hidden posture straps help alleviate back pain during sleep.

Menopause-Friendly Designs: Brands like Pyjama Party use phase-change material (PCM) panels to manage night sweats, with discreet ventilation zones.
