How to dissipate heat in summer
How to dissipate heat in summer? Summer is coming. Every summer, the temperature in some places is above 30 degrees every day, so people don't dare to stay outdoors at all. If there is no air conditioning indoors, heat dissipation becomes the most important thing. So how to dissipate heat in summer?
How to dissipate heat in summer 1 1 reduce heat sources?
Close the blinds or curtains. About 30% of the excess heat comes from the window. Closing the curtains can prevent the direct sunlight from heating the room. If there are no blinds or curtains in the room, especially those facing south or west, you can buy some. Covering windows with curtains can reduce the indoor temperature by 20 degrees Celsius.
2. Turn off all unnecessary heating equipment, electrical appliances and lights.
Any running equipment will increase the heat in the room. Unplug or turn off all unused devices. Computers and televisions, in particular, generate a lot of heat, as do incandescent lamps. Turn off the lights in the room if you can.
Step 3 clean up debris
Many clothes and other debris absorb heat and stay in the room. The less messy the room is, the more space there is to heat up and cool down faster. Too much debris will also block the airflow and make the room hotter. Put the pile of clothes on the floor in the closet and close the door.
4. Open a window and close other rooms in the room.
If it is hotter indoors than outdoors, it may be because the walls absorb too much sunlight during the day. Open the window of the room and let out the heating. The temporarily unused part of the room is also closed. This can make the room cool down faster.
Step 5 let the air circulate
Turn on the ceiling fan and adjust the settings. The ceiling fan is very effective. It can make air flow indoors and produce ventilation effect. When the ceiling fan rotates, it can make the hot air rise, and it can also make the room cool down faster. If the ceiling fan is not turned on, please turn it on immediately. If the ceiling fan has three settings: low, medium and high, please turn on the highest one.
Step 6 use curtains
If you use curtains, choose a middle tone and use a white plastic backing, which can effectively insulate the heat. Hang it as close to the window as possible. The sun visor can also effectively insulate heat, and should be installed as close as possible to the window glass to form a closed heat insulation space. Buy a white and black double-sided sunshade.
How to dissipate heat in summer 2 (1) Aromatic refreshing method It is hot in summer, which easily makes people tired and fidgety. Therefore, artificially creating a cool microclimate is very beneficial to the body and spirit.
The method of keeping fragrance and cooling down is to hang a pot of chlorophytum by the window; There are jasmine and cordate telosma on the desk; Sprinkle a little balm, toilet water or violet perfume on the light bulb.
Let a clear fragrance flow in the room, giving people a faint coolness from the feeling. In the light fragrance environment, people's emotions and feelings are in pleasure, and unconsciously, the heat disappears.
(2) Sensory cooling method When the weather is hot, decorate the walls, ceilings, curtains and sofa cover with cool pigments such as light green, light blue, tile charcoal and milky white, or hang a landscape painting such as Snow Peak of Iceberg, Flowing Bridges, and Xiuzhu in Maolin on the wall.
In this cool environment, you can feel the natural cool wind outside and taste the sweetness of mountain springs, as if you were in a cool forest.
Because human vision is very interesting, wonderful things quickly spread from the eyes to the bottom of my heart, making you forget the temporary anxiety. In addition, like icebergs and flowing water, people are "cold when they see cold" and have a feeling of quenching their thirst by looking at plums.
(3) Ice-making cooling method Families with conditions can completely use the method of making ice in the refrigerator to cool down. The specific way is to make a few pieces of ice with plastic boxes or enamel boxes every day and put them under the bed or in the corner at night.
Because ice cubes can absorb excessive heat indoors and reduce the indoor temperature. You can also melt ice cubes in water and sprinkle some water on the floor or wall to reduce the temperature.
Obviously, making ice to cool down is a physical method. In practice, different treatments should be made according to the layout and structure of the family. This cooling method, if combined with light blowing, can achieve the cooling effect that air conditioning can't.
(4) Ventilation and cooling method In summer, redundant or temporarily unused furniture can be removed, so that the living room has a spacious space, which can sweep away the depression caused by the crowded living room. Conditional families can use rattan and bamboo instead of sofas, chairs and other furniture.
Often open doors and windows in the morning and evening, so that air convection will naturally generate wind, making the room cool and cool. If the family level is low, you can install the exhaust fan on the opposite window or wall, and turn on the exhaust fan according to the daily wind direction, especially when you sleep at night, so that the cool wind outside can blow slowly.
(5) As the name implies, the way to prevent heatstroke and enjoy the cool is to prevent the penetration of heat waves. The simple method is to install a sunshade above the sunny window, paste white paper or draw dark curtains outside the window glass;
If possible, you can hang blinds, which can keep out the bright light from the sun and the heat it brings. Close the doors and windows before going to work every day, close the curtains, keep the room cloudy and reduce indoor and outdoor exchanges, which can effectively block the outdoor heat wave.
At night, after the sun goes down, the temperature drops slowly. When you open the window again, there will be a natural coolness.
(VI) Plant cooling method Scientifically and reasonably planting some plants indoors and outdoors also has obvious cooling effect in summer.
If plants such as Parthenocissus tricuspidata, grape, morning glory and wisteria are planted around the room, and these plants are allowed to climb along the wall or bracket, a green "arbor" can be formed, which can not only block the direct irradiation of the scorching sun, but also absorb dust and beautify the environment.
The reasonable distribution of climbing plants has changed the microclimate structure of the living room. As a vegetation, it can isolate the direct radiation of the sun and release some water. Therefore, this is a good method worth advocating.
How to dissipate heat in summer 3 Don't dress too exposed.
In summer, the thinner the clothes, the more exposed parts of the body. They thought it would cool off the summer, but it wasn't. When the outside temperature is higher than the skin temperature, the skin will not dissipate heat, but will absorb the heat from the outside environment. If the exposed area is too large, thermal radiation will easily invade the skin, but it will be hotter, which is why it will feel hotter in summer.
Experts suggest that you should wear light, breathable and loose clothes in summer, preferably light color, and the exposed area should not exceed 25% of the total surface area of the human body. Try to wear hats, umbrellas, sunglasses and long-sleeved clothes when going out to protect your skin.
Drink hot tea
Cold drinks can only relieve summer heat temporarily, but can't relieve fever and quench thirst for a long time, and you can't eat too much, otherwise the temperature of the stomach and intestines will drop, causing irregular contraction and inducing abdominal pain and diarrhea.
Drinking hot Chaze can generally stimulate the relaxation of capillaries, but the body temperature is obviously reduced. Studies have confirmed that drinking a cup of hot tea for 9 minutes can reduce the body temperature by 1℃ ~ 2℃, and the cooling can last for more than 15 minutes.
Therefore, drinking hot tea in summer is a simple and easy way to cool off the heat. You can drink tea, fruit tea, scented tea and so on alone. You can also clean10g of dried tangerine peel, tear it into small pieces, put it in a cup filled with 5g of green tea, add boiling water and cover it for about10min, remove the residue, and add a piece of crystal sugar before drinking.
Koreans have the habit of eating ginseng chicken soup for tonic in dog days, which is also an effective way of "heating with heat".
Take a hot bath.
Taking a cold bath in summer will make the skin capillaries contract, and it will feel hotter after washing. Although bathing with hot water will sweat more, it can dilate capillaries, which is beneficial to the body to emit heat, promote metabolism, accelerate the elimination of metabolites such as lactic acid, and eliminate human fatigue. The water temperature is generally controlled at around 30℃.
Hot water soaking feet
Can make the pores of the whole body open, which is beneficial to heat dissipation. Therefore, soaking feet with hot water in summer can promote perspiration, enhance sweat gland function and improve heat resistance. You can soak your feet with warm water of about 40℃ before going to bed every night (ankle joint is flooded), and soak for 15~20 minutes each time (during which you can heat the water to keep the water temperature) and feel a little sweaty.
Wipe your body with a hot towel.
In summer, the body is prone to sweating. Sweating in time can make the skin breathable, but you must use a hot towel to avoid stimulating capillaries and adapt to the law of human body cooling.
Eat hot food
Many people think it's hot, and some meals can be eaten without heating. This view is wrong. Hot and humid environment is easy to breed pathogenic microorganisms such as bacteria, and heating can play a role in disinfection and sterilization, protecting people's bodies from bacteria. When cooking, you can properly use some seasonings such as green onions, garlic and ginger, which can not only increase body perspiration, but also prevent heatstroke and cool down.
Exercise produces hot sweat.
Proper physical exercise can enhance the human body's heat resistance, improve the body temperature regulation function, and at the same time, it can also enhance physical fitness and prevent heatstroke. In order to avoid heatstroke, summer exercise time can be around 6 or 7 pm, and fitness programs can be swimming, walking and Tai Ji Chuan.
Wear cotton clothes with good sweat absorption and permeability during exercise, dry the sweat after exercise, and then use the air conditioner after the body temperature recovers.
Hot compress navel
It is one of the ancient methods to apply 1~2 times a day to the navel with a hot water bottle or hot towel at about 40℃ and take it off after a few minutes. You can also rub your hands on an empty stomach every night before going to bed, put your palms on the lower left and upper right and stick them on your navel, and do a small amount of rubbing counterclockwise, 20 to 30 times each time.
Moderate temperature sweating
Sweating is a way for the human body to dissipate heat. However, due to the wide application of air conditioners, the sweat glands of people who have been in a constant temperature environment for a long time are almost idle, and they don't sweat often even in the sweating season in summer, which is harmful to health.
Starting from conforming to the laws of the four seasons and life, you should sweat when you sweat. Ginger has three functions: sweating and relieving exterior syndrome, warming and stopping vomiting, and detoxifying. Drinking ginger soup often has the effect of sweating and relieving summer heat. You can soak shredded ginger in water every morning, or soak ginger slices in black tea, and don't eat ginger at night.
