The temperature difference between summer and winter in Japan is thought to be close to 40 degrees Celsius.
Cold temperatures affect not only the surface temperature of the body, but also the core body temperature.
Isn't there a lot of people who have felt that old wounds hurt in the past hurt in winter? Pain from old wounds is not only caused by changes in atmospheric pressure at the turn of the season, but is also deeply related to poor blood circulation due to cold weather.
Heat shock (*1), which has become more common on TV in recent years, is also caused by the overload stress on the circulatory system caused by the cold.
(*1) Heat shock is a rise and fall in blood pressure due to changes in temperature, causing heart and blood vessel diseases.
During the winter season, not only the heart and blood vessels, but also the internal parts of the body, such as joints and muscles, are heavily burdened, so it is necessary to prepare well before training (exercise).
Preparing to train in cold weather
➀ Blood pressure measurement
Have you ever heard that blood pressure tends to rise in winter?
When the body feels cold, the muscles such as skeletal muscles and smooth muscles contract to generate heat energy to maintain body temperature. , the sympathetic nervous system becomes dominant, and blood pressure and heart rate rise.
Due to changes in temperature, physiological reactions are occurring in the body to adapt to the environment without realizing it. If you don't realize how hard your body is working, and you put more strain on your body, you may end up putting more strain on your body. Good.
② Careful warm-up
In the cold winter season, the body's muscle tone increases and the viscosity of the muscles is high in order to maintain body temperature. In addition, the effects of coldness increase the viscosity of the soft tissue surrounding the joints, reducing the functionality and flexibility of the body.
That's why a thorough warm-up is important for winter training, as it prepares the heart, prepares the joints, prepares the muscles, but also prepares the mind. As a method to warm the body from the inside, it is possible to warm the core body temperature by performing methods such as jogging and dynamic stretching (dynamic stretching) for about 15 minutes. It is a good idea to use the fact that you were able to sweat on your body as a guideline.
If you start training or your main exercise without warming up, your muscles will remain highly viscous and your movements will be poor. Make sure to warm up carefully as the risk increases.
③Other ways to warm the body
In addition to carefully warming up the body from the inside, one of the approaches is to warm the body from the outside by taking a bath or shower. By warming the body surface temperature, the resistance to the cold is lowered, and as a result, the body becomes able to move more easily, which leads to an increase in the core body temperature.
As a way to warm your body from the outside, it is also a good idea to prepare clothes suitable for cold weather, hats, gloves, neck warmers, etc. It also allows you to regulate your temperature during training by wearing layers of light clothing that you can adjust while exercising.
Another way to warm your body from the inside is to choose foods and drinks that warm your body. Ginger, which contains gingerols and gingerols, promotes blood circulation and warms the body. Grab a drink that warms you from the inside out and get ready for your workout.
adapt the body to the cold
In order to train in the cold winter season, preparation is necessary regardless of the level of the stage, but it is also essential to acclimatize the body to the cold.
No matter how cold it is, if the difference between the outside temperature and the indoor temperature is too large, you will not be able to develop resistance to the cold, and your body temperature regulation function will not work, so your body will be cold and your immune system will be weakened. This can lead to a loss of ability and a loss of health.
Get ready to move your body, and if you move your body, it will warm you up from within, and you will gradually develop resistance to the cold.
In winter, it is easy to dry out, and the body tends to become dehydrated without realizing it. Make sure to hydrate frequently during training so that you can perform well.
During the cold winter months, the body needs a lot of energy to keep warm.
This is probably the reason why it is said that dieting is winter.
During the cold season, we tend to not want to move or want to hide under a futon or a kotatsu, but prepare your body according to the season and enjoy winter training so that you can get the most out of your training. let's go
