In recent days, the cold weather has hit again.
In such weather, it is very important to keep out the cold correctly to help us stay healthy and comfortable.
Let's take a look at some popular science knowledge in life and how to deal with cold weather correctly.
Pay attention to indoor air
Maintain good indoor air circulation. Although in winter weather, many people like to close doors and windows and turn on the heating to keep the room warm. However, doing so will lead to the drying of the indoor air, which can easily cause problems such as dryness, sore throat, and cough.
The right thing to do is to keep the indoor air circulating. Some doors and windows can be opened appropriately and ventilated regularly to allow fresh air to enter the room and reduce air pollution.
How to properly protect yourself from the cold
We should choose the right clothing. In cold weather, it's crucial to keep your body warm. Choosing the right clothing can be an effective way to keep out the cold. We can choose to wear at multiple levels, such as wearing underwear, woolen sweaters, down jackets, etc. Underwear can keep you warm, while an outer coat will prevent the cold wind from blowing directly into your body.
We can also choose some materials that have a warming effect, such as wool, down, etc. These materials provide better thermal insulation, keeping us warm while breathable and avoiding the cold sensations caused by sweating.
In addition, we need to keep our hands and feet warm. In cold weather, our hands and feet are often the parts of the country that are most prone to cold. The correct way to keep warm is to wear thick socks and gloves, which can effectively avoid direct invasion of hands and feet by cold air.
For the elderly and children, it is more important to keep their hands and feet warm, because their peripheral blood vessels are more fragile and more susceptible to cold.
Eating a reasonable diet is also an important part of keeping out the cold. In cold weather, our bodies need more energy to maintain body temperature. Therefore, we can consume high-calorie foods in moderation, such as nuts, dried fruits, animal fats, etc. These foods can provide enough energy to keep our bodies warm.
Moderate intake of foods rich in vitamin C, such as citrus fruits and vegetables, can strengthen immunity and prevent cold-induced diseases such as colds.
We also need to exercise moderately. Cold weather can easily make people feel lazy and frustrated, but moderate exercise can help us maintain our body's calorie production and improve immunity.
You can choose some indoor exercises, such as yoga, dancing, etc., or go outside for light exercises, such as walking, jogging, etc. Exercise can promote blood circulation, enhance physical fitness, and improve the body's resistance, so as to better cope with cold weather.
Keeping indoor air ventilated, choosing the right clothing, keeping your hands and feet warm, eating reasonably, and maintaining moderate exercise are all scientifically feasible methods that can help us better cope with cold weather and stay healthy.
Let us live warm, comfortable, healthy and happy in the cold winter.
