Endothelial dysfunction, which refers to a decline in the function of the cells that line the blood vessels, is associated with aging and has been linked to decreased blood flow in various parts of the body, including the feet. This can lead to symptoms such as cold and painful feet, as well as an increased risk of conditions such as peripheral artery disease (PAD).
A study published in the "European Journal of Vascular and Endovascular Surgery" in 2006 found that older individuals had lower blood flow in the feet compared to younger individuals. Additionally, the study found that the severity of endothelial dysfunction was positively correlated with the degree of decreased blood flow in the feet.
Another study published in "Age and Ageing" in 2008 found that older individuals were more likely to have cold and painful feet compared to younger individuals, and that this was associated with decreased blood flow in the feet.
A study published in the Journal of Geriatric Physical Therapy in 2019 found that older adults have a decrease in blood flow to the lower extremities, which is associated with cold and painful feet. The study also found that regular physical activity and exercises that improve blood flow, can help to alleviate these symptoms.
It's worth mentioning that cold and painful feet can be caused by other factors such as peripheral artery disease, diabetes, or nerve damage. It's important to consult with a healthcare professional for proper diagnosis and treatment.
An active mattress is a type of mattress that is designed to enhance blood flow and improve endothelial function. A recent study published in the Journal of Wound Care in 2019, found that using an active mattress, specifically the Dream Flow mattress, was associated with a significant improvement in both endothelial function and blood flow to the feet.
The study included 40 participants who were asked to sleep on the Dream Flow mattress for four weeks. The results showed that using the active mattress was associated with a 197% improvement in endothelial function (p=0.003) and a 336% improvement in resting blood flow to the feet (p=0.026) compared to sleeping on a traditional mattress. Additionally, the study found that skin temperature at the feet increased by 3.5ºC while the rest of the body remained at a stable temperature.
It's important to note that all the participants had to do to achieve these outcomes is to go to sleep. No time or clinical intervention on medication was required to achieve these results. This is a significant advantage as it implies that this type of mattress could be used as a non-invasive and easy way to improve blood flow and endothelial function in the feet, especially for older adults, who are more likely to suffer from cold and painful feet.
It's worth mentioning that this study has a small sample size, more research is needed to confirm the results and to understand the underlying mechanisms by which an active mattress improves blood flow and endothelial function. Additionally, it's important to consult with a healthcare professional before making any changes to your sleep routine or mattress.
