It is very hot in summer. How can I sleep better without air conditioning?

Because it is hot in summer, there is really no effective way except to turn on the air conditioner.

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. Open the doors and windows for ventilation in the morning and evening when it is cool, and close the doors and windows during the day, especially at noon, to isolate the invasion of outdoor hot air, and draw a light curtain to block the sun and reflect thermal radiation, so that the room becomes cool.

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, after wiping the floor indoors with a wet mop, turn on the ceiling fan to evaporate and absorb heat; You can also put a basin of cold water (preferably ice cubes) in front of the fan, which can reduce the indoor temperature and 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.

If possible, you can add an insulation layer on the roof to prevent the indoor temperature from being too high.

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.
