Generally speaking, it is advisable to take a lunch break of 20 to 40 minutes in summer. If it takes too long, you will feel tired. Don't get up in a hurry after waking up, and immediately devote yourself to work or study, because there is insufficient blood supply to the brain at this time, which may cause temporary dysfunction and make people feel dizzy. It is best to lie down for about 2 to 3 minutes before getting up.
Don't turn on the air conditioner for a long time when sleeping at night. Before going to bed, you can turn on the air conditioner around 28, and go to the summer appropriately. After sleeping, you can choose to turn off the air conditioner. I really think it's very hot to put a pot of cold water in the room with an electric fan. Soaking feet with hot water every night before going to bed is a necessary course all year round. Only by soaking your feet in hot water can you have a good sleep. When sleeping, keep your head cold and your feet warm. Cover your feet with a blanket first.
