Is the high heart rate when running in summer due to heat?

When summer comes, many running enthusiasts have such confusion: Why does the heart rate soar when running? Is it because of the hot weather? Also, does sweating more make weight loss more effective? Today we will uncover these mysteries.

Is heat the main reason for the high heart rate when running in summer?

1. Temperature influence: The high heart rate when running in summer is indeed a key factor. When the weather is hot, it is more difficult for the human body to dissipate heat. In order to maintain normal body temperature, the body will speed up blood circulation and let the heat dissipate through the skin. This is like giving the heart an "expedited order", and the heart rate naturally increases. Just like when you run in a steamer, the heart also has to speed up the "working rhythm".
2. Other factors: In addition to heat, humidity will also "make trouble". In a high humidity environment, sweat is difficult to evaporate, and the body is more difficult to dissipate heat, and the heart rate may rise further. In addition, the body loses electrolytes quickly in summer. If they are not replenished in time, it will also affect heart function and cause unstable heart rate. In addition, if the intensity of running suddenly increases in summer, the heart cannot adapt for a while, and the heart rate will also rise.

Is sweating more conducive to weight loss?

1. The relationship between sweating and weight loss: Many people think that sweating more can consume more fat and have a better weight loss effect. In fact, this is a misunderstanding. Sweating is mainly the body's way of regulating body temperature. When the body produces too much heat, it dissipates heat through sweating. The amount of sweating may be just because of hot weather, thick clothes, or well-developed sweat glands, which does not necessarily mean that more calories are consumed. For example, if you stand still in the sun, you may sweat profusely, but this does not mean that you are losing weight.
2. The key to weight loss: The key to weight loss is the calorie gap, that is, the calories consumed must be greater than the calories consumed. When running, keep the heart rate in the appropriate range and continue to exercise to effectively consume fat. Generally speaking, the aerobic exercise heart rate reaches 60% - 75% of the maximum heart rate (maximum heart rate = 220 - age), and the fat burning effect is better. Therefore, if you want to lose weight, don't just focus on the amount of sweating. It is more important to control the intensity and duration of running.

When running in summer, high heart rate is related to heat, but it is not entirely the fault of heat; sweating a lot does not mean good weight loss effect.

Understand these facts and adjust running strategies, such as choosing to run in the cool time of morning and evening, replenishing water and electrolytes in time, and controlling exercise intensity, so that you can run healthily in summer and achieve the goal of weight loss. Running enthusiasts, take action quickly and enjoy the fun of summer running!
