A study published in the medical journal Neurology found that women with high physical fitness at middle age were nearly 90% less likely to develop dementia decades later, compared to women who were moderately fit. The study measured cardiovascular fitness based on an exercise test and found that highly fit women who did develop dementia did so an average of 11 years later than moderately fit women. However, the study only shows an association and not cause and effect, and more research is needed to determine if improved fitness can positively affect the risk of dementia and when during a lifetime a high fitness level is most important. This underscores the importance of maintaining an active lifestyle and engaging in regular exercise, as it can have significant benefits for both physical and cognitive health.

A study found that fasting can activate a process called fatty acid oxidation, which enhances the function of intestinal stem cells during both homeostasis (normal state) and aging. Fatty acid oxidation is a process by which fatty acids are broken down and converted into energy that the body can use. Intestinal stem cells play a crucial role in maintaining the health and function of the digestive system, and their decline can contribute to various health problems, including age-related digestive disorders. The study suggests that fasting may help to mitigate this decline by boosting fatty acid oxidation and promoting the healthy functioning of these cells. Fasting can have positive effects on intestinal stem cells, which may be beneficial for overall digestive health during both normal homeostasis and aging.

The study found that people who used a sauna 4-7 times per week were 61% less likely to suffer a stroke than those who used a sauna only once per week. A stroke occurs when blood flow to the brain is interrupted, leading to damage to brain tissue. It is a serious and potentially life-threatening condition that can have long-lasting effects on a person's health and well-being. The study suggests that regular use of a sauna may help to protect against stroke by improving cardiovascular health. Saunas have been shown to have a number of beneficial effects on the body, including reducing blood pressure, improving circulation, and promoting relaxation. Regular use of a sauna may be an effective way to reduce the risk of stroke, as people who used a sauna 4-7 times a week were found to be significantly less likely to suffer a stroke than those who used a sauna only once per week. However, it is important to note that more research may be needed to confirm these findings and to fully understand the mechanisms by which saunas may be protective against stroke.
