"Enhancing Memory and Reducing Dementia Risk Through Scent During Sleep and Showers"
A study by the University of California, Irvine suggests that diffusing fragrances such as rose, orange, and lavender during sleep can significantly improve cognitive performance in older adults. The research found a 226 percent improvement in cognitive tasks among participants who were exposed to a variety of scents compared to a control group. This finding indicates that sensory stimulation through smell could potentially slow cognitive decline and conditions like dementia, offering a simple and enjoyable intervention for maintaining brain health.
