In weather, students will turn on the fans in the classroom, but people will feel cool.

There is no air conditioning in summer, and some simple methods can also make your room cooler.

1, reasonably open and close doors and windows. When it is cool in the morning and evening, open the doors and windows for ventilation, so that the air can circulate. During the day, especially at noon, close the doors and windows to isolate the invasion of outdoor hot air, and draw a light curtain to block the sun and reflect the heat radiation, so that the room becomes cool. If the window glass can be replaced with double layers, the sound insulation and heat preservation can be done once and for all.

2, balcony greening, courtyard greening. Some data show that planting grapes, morning glory, Parthenocissus tricuspidata and some flowers and plants on the courtyard balcony can reduce the temperature of the attached wall by 5℃ ~ 14℃ and the indoor temperature by 2℃ ~ 4℃.

3, indoor use of fans and water evaporation cooling. For example, wiping the floor with a wet mop indoors can make the ground moisture evaporate and absorb heat, which can not only reduce the room temperature, but also increase the air humidity.

4. It will make people feel comfortable to clean up the room in summer, so that there is more space in the room. Avoid indoor clutter, which not only makes people feel stuffy and breathless, but also makes people feel irritable.

In summer, sweat evaporation is the main way to dissipate heat, so heat removal by heat is a better way.

1, hot towel to wipe the body: sweating is inevitable in summer. Sweating in time can make the skin breathable, but it must be hot to adapt to the cooling rhythm of the human body.

2, take a hot bath: taking a cold bath in summer will shrink the skin, and it will feel hotter after washing, while taking a hot bath will sweat more, but it will expand the capillaries and help the body expel heat.

3, hot water to wash feet: the foot is called the second heart, and there are representative areas of the whole body and reflection points of internal organs on people's feet. The ancients said, "Washing feet before going to bed is better than tonic."

4, drink hot tea: cold drinks can only temporarily relieve summer heat, can not permanently reduce fever and quench thirst, but drinking hot tea can stimulate the whole body capillaries to relax, but the body temperature is significantly reduced, which is a simple and easy recipe.
