Sensory Wellness Tips for Ageing Skin

Aging and Sensitivity to Touch

Ageing brings about various changes in the human body , including a decline in hearing and vision . However , a recent study published in Frontiers in Aging Neuroscience has revealed an interesting phenomenon related to our sense of touch . Contrary to popular belief , older adults do not necessarily experience a decline in touch sensitivity across all regions of the body . The study found that sensitivity only decreases in hairless skin areas , while hairy regions like the cheeks and forearms remain as sensitive to touch as they were in earlier years.

Research Findings and Methodology

The researchers recruited 96 left - handed women aged between 20 and 75 years to test the sensitivity of their skin in three different regions : the hairless tip of the right index finger , the right forearm , and the right cheek . Participants were asked to perform various tasks to measure their ability to sense touch , such as moving their finger over grooved plates or detecting the application of calibrated forces of monofilaments . The results showed that while older women exhibited decreased touch sensitivity in the index finger , no such decline was observed in the cheek and forearm.

Implications and Discussion

The findings of the study shed light on the importance of touch sensitivity as individuals age . It was surprising to note that hairy skin areas retain their sensitivity to touch due to the presence of mechanoreceptors that detect pressure and touch . The researchers speculate that the preservation of touch sensitivity in these regions is attributed to the role of hair as an antenna that transmits mechanical stimuli . Additionally , maintaining sensitivity on hairless skin can be achieved by avoiding extreme temperatures , air pollution , excessive alcohol consumption , smoking , and sun exposure.

Overall , the study provides valuable insights into how our sense of touch evolves with age and offers practical advice on maintaining skin sensitivity . As humans , touch remains a crucial method of communication and connection , emphasizing the significance of preserving this sensory function throughout the lifespan . Efforts to protect our skin and avoid damaging factors can contribute to maintaining optimal touch sensitivity , enhancing our overall well - being and quality of life.
