Record-breaking heat continues day after day. Every day, the TV broadcasts messages telling people to stay indoors. But cool seniors rebel and ignore them. He knows that the ability to adapt to heat that rivals the heat of summer is called heat acclimatization. If we rely too much on home air conditioning, our ability to acclimatize to heat will decrease. When our body temperature rises, we sweat to lower our body temperature. Exercise that makes us sweat moderately is an effective measure against heat stroke. He understands that heat acclimatization is achieved in people who exercise on a daily basis.
Cool seniors know that strength training is as important as aerobic fitness. When we think of strength training, we tend to think of high-intensity exercise like weight training. But strength training does not just mean doing advanced strength training at a sports gym. Low-intensity strength training is also useful. Three days of strength training a week is enough. In a sense, it may be easier to take a break from exercise if you think it’s okay to take 4 days off out of 7 days. The increase in skeletal muscle through muscle training is itself effective in preventing and improving lifestyle-related diseases. Increasing muscle mass increases metabolism and improves fat burning efficiency. Muscle training prevents obesity and lifestyle-related diseases.
Aerobic exercise increases the heart rate and blood flow. The increased blood supplies oxygen and nutrients to each organ. Each organ receives this and becomes more active. Aerobic exercise is expected to reduce the risk of arteriosclerosis, which is related to myocardial infarction, and is also expected to be a factor in preventing dementia. Muscle training is not inferior in terms of effectiveness. In addition to moving and supporting the body, muscles also secrete hormones. These are called “myokines.” More than 30 types of myokines have been discovered so far. Myokines secreted from skeletal muscles act on various organs. Another myokine, “SPARC,” is said to have the effect of suppressing colon cancer. Even in your 80s or 90s, it is possible to increase the amount of muscle that secretes myokines through training. The rebellious spirit of cool seniors not only contributes to their physical and mental health, but also seems to act as a barrier against illnesses that appear later in life.
