Is minus a few degrees suitable for outdoor sports?

Temperatures below zero are suitable for outdoor exercise, but there are a few caveats.

Precautions: 1. It is best not to exercise in snow or fog.

On snowy or foggy days, the road surface or playground is slippery, and the air quality is second.

It may be worse, and the weather is relatively cold, and the conditions for exercising are extremely unfavorable, so it is not suitable for outdoor exercise.

2. The clothes you wear should be layered.

Many people think that outdoor workouts are all it takes to wear only sportswear, on the grounds that they won't get cold when exercising. However, when the human body produces more heat during exercise, it is only in the middle of the body, and it is very easy to be affected by the outside temperature. Therefore, you should add clothing in time for rest and at the end of your workout.

At the same time, you can properly wear gloves, ear protection and other protective equipment.

3. Prepare for a warm-up before exercising.

It is best to start with systematic stretching exercises and avoid sudden exertion. After stretching, a slight run and jump on the spot can warm up the joints of the whole body.

4. Grasp the rhythm of exercise.

In order to warm up as soon as possible, some people run fast at the beginning to achieve the purpose of generating a large amount of heat, so that the body feels warm. However, speeding does not last long, and when the speed drops, the amount of heat generated decreases dramatically, causing the body temperature to drop.

Therefore, it is important to control the pace of exercise, pay attention to the gradual progress, too fast may cause the airway due to inhaling too much cool air.

Under the weather. You may sweat a lot after a workout, so you should wipe it off immediately and change into dry clothes.

A few degrees below zero is the limit has not been studied, but -30 ° is no problem, we ride a bicycle to the next city at the lowest temperature, the same day round-trip, and as long as you pay attention to the warmth of the ears, hands and feet, the underwear is guaranteed to be sweat-wicking and quick-drying material is no problem, because this function will not feel cold at all when you get off the car to rest, and you can't feel winter at all along the way, just like the beginning of spring, it is as warm and comfortable as spring, and it is definitely more comfortable than the hot summer exercise, but the clothes should be worn as little as possible, and it is a little cold when you just go out, After a few minutes, the body will warm up, and if you wear too much, you will always be hot and sweat a lot along the way.

Outdoor construction is prohibited below freezing. The Hefei Municipal Urban and Rural Construction Committee issued an emergency notice, requiring all construction sites to do a good job in preventing and responding to low-temperature freezing disasters after snow. According to the requirements, outdoor construction is prohibited below zero temperatures.

The notice made it clear that all construction sites should remove the water and snow on the construction site in a timely manner, and organize personnel to remove the snow and ice on the roofs and safety sheets of migrant workers' dormitories, temporary facilities, industrial plants under construction and other buildings under construction on the premise of ensuring safety, so as to prevent collapse accidents.

It is necessary to strengthen the anti-skid measures of the main passages such as scaffolding, ramps, unloading platforms, and working layers; Strengthen the anti-skid of transport vehicles and the cleaning of stagnant water on site; Strengthen the maintenance of tower cranes and construction elevators to prevent accidents; Strengthen the inspection of weak parts that are prone to accidents, such as scaffolding, formwork support, and deep foundation pit support. Conscientiously do a good job of shoveling ice and snow around the construction project.

The notice emphasizes that outdoor construction is prohibited below zero, and it is strictly forbidden for large equipment to work at low temperatures. All construction sites should strengthen the unified management of winter heating, and the public heating facilities of the dormitory should be managed by special personnel, and it is strictly forbidden to use electric stoves or open flames for heating in the dormitory to prevent fire accidents. Strictly prevent gas poisoning, fire and electric shock.

The state stipulates that employees are not allowed to work outside below minus 10 degrees Celsius to ensure the health of employees.

There are no specific regulations on this issue from the state. Because the temperature varies from place to place. There are also differences in the temperature required by different industries.

If it is stipulated, then how does it work when you say that the Antarctic expedition works? If the temperature is too low and poses a hidden danger to the work or building materials, then someone will naturally arrange it.

For concrete construction, low temperature is minus 5 degrees Celsius to prohibit construction; There should be no practical limit to the high temperature, and the concrete pouring should be sprinkled with water to cool down.

The national regulations are about minus 10 degrees Celsius, that is, they are not allowed to work outdoors.

1.Below -9 Don't exercise outdoors. Jenny Hadfield, an American sports expert, said that too low temperatures will not only greatly reduce the quality of exercise, but also make it easy to get injured. When the temperature is below 15 degrees Fahrenheit (which is below zero), it is best to exercise indoors.

2.Love to sweat and wear less cotton underwear. A new study from Drexel University published in the American magazine "Red Book" found that cotton underwear dries slowly after being wet with sweat, which will increase the risk of mold infection.

Cynthia Bayer, an American nursing expert, suggests that it is best to choose bamboo fiber underwear with better moisture absorption and perspiration management when exercising. In addition, underwear should not be too tight when exercising, and it is best to choose shorts with loose edges.

3.Warm up for 6 minutes. Dr. Andriy Fladken, a professor at Bloomsburg University in Pennsylvania, USA, introduced the "6-minute warm-up method", which can increase the effectiveness of exercise by 24%.

The specific steps are: sprint for 2 minutes to increase body temperature and muscle oxygen uptake, but do not overdo it; Stretching the muscles of the whole body for 3 minutes can improve the flexibility of the body; "Exercises" for 1 minute, such as lifting your arms before lifting dumbbells, jogging in place for a while before running, etc., can help improve body coordination.

4.Take a warm shower before exercising. The cooler the outside temperature, the longer it will take to warm up. Hadfield says it's a good idea to take a hot shower before exercising to help warm up, if conditions permit.

5.Wear a little less. After exercising for a while, the body temperature will rise, so you should wear less clothes to facilitate heat dissipation and prevent colds.

Experts recommend at least 10 minutes to warm up, wait for a slight pant and a little sweating, and then start exercising Although the blood is boiling, be careful not to warm up enough, causing cramps, muscle strains, and even increase the chance of hypertension and cardiovascular disease.

Therefore, it is recommended to warm up for at least 10 minutes in cold weather, and wait for the breathing to slowly accelerate, the heart rate to increase, the slight panting and a slight sweating, and then start the next exercise plan.

There are also exercises should avoid windy and snowy days, outdoor activities should not be too little, sportswear can be worn under sweaters or thermal underwear, when the temperature is low, you can add a jacket or thick fleece jacket outside. Exercise to the point of a small amount of sweating is fine. Wear thick clothes quickly after exercising to avoid catching a cold after sweating.

Many people don't go to exercise because they are afraid of the cold, but in fact, the benefits of outdoor exercise are obvious, and outdoor exercise can also be carried out when it is a few degrees below zero. Just pay attention to wear light and warm clothes, exercise to stretch the body, you can choose some lighter exercises, such as shuttlecock kicking, etc. Don't take too long.

Don't go out if the air quality is bad.
