The watermelon season is here, are you ready?

Lixia tomorrow
.
Every year on May 5 or 6 of the solar calendar, when the sun reaches 45 degrees of the yellow longitude, "the bucket refers to the southeast, the dimension is the Lixia, and everything grows up here, hence the name Lixia", which also indicates the beginning of summer
.
Summer is an important solar term when crops enter the peak season
.
Therefore, in ancient times, Li Xia was attached great importance
.
The emperor will lead a hundred officials of civil and military forces to the southern suburbs of the capital to welcome the summer and hold a summer welcoming ceremony
.
To welcome the summer, you must wear a red dress with a vermilion jade pendant.
Even the horses and car flags must be vermilion red to express the prayer for a good harvest
.
In order to welcome the summer, some places have the custom of eating "Lixia eggs", thinking that eating eggs in Lixia can strengthen the body
.
The day before Lixia, the family used tea or walnut shells to boil eggs or duck eggs.
The egg shells slowly turned red and the house filled with fragrance
.
There is a custom of cooking tender broad beans in Jiangnan water town
.
There are also people who eat "Lixia Rice", adding bamboo shoots, peas, broad beans, amaranth and other condiments to the rice, which means "bundance of grains"
.
In summer, thunderstorms increase, the temperature rises significantly, the body's metabolism is accelerated, energy consumption is high, and it is easy to sweat, and sweating will lose water, water-soluble vitamins and other micronutrients
.
High temperature will also reduce the secretion of digestive juice of the human body, which is prone to decrease in appetite compared with other seasons
.
Therefore, reasonable schedules should be arranged for work and rest, and nutrients should be supplemented in time
.
In the summer diet, we should pay attention to "four needs and four don't"
.
　　1.
Everyday fruits and vegetables, not greasy food
.
　　There are many kinds of vegetables and fruits in summer, and they are rich in nutrition
.
Common bitter gourd, wax gourd, tomato, loofah, pumpkin, cucumber, watermelon, etc.
on the market have the effect of cooling and expelling heat
.
Especially some dark fruits and vegetables, such as carrots, mangoes, red and yellow tomatoes, are rich in vitamins, minerals, and healthful phytochemicals.
If eaten every day, they can enhance immunity, benefit cardiovascular health and prevent cancer
.
Eating greasy food will increase the burden on the gastrointestinal tract, people will feel abdominal distension, reluctance to eat, and fatigue
.
　　2.
Drink plenty of water instead of sugary drinks
.
　　Water is the most abundant substance in the human body, accounting for about 60% to 70% of an adult's body weight.
Most of the substances in the blood are water, and tissues and organs such as muscles, lungs, and brain also contain a lot of water
.
Water also plays a role in material transportation, body temperature regulation and lubrication in the body
.
Therefore, drink plenty of water every day
.
You should drink boiled water in small amounts for many times, and you can also drink green tea, mung bean soup or sour plum soup to relieve your thirst
.
Drinking more soup in summer can adjust the taste and increase appetite
.
　　Studies have found that excessive consumption of sugar-sweetened beverages can increase the risk of dental caries and obesity, and have a negative impact on health
.
Therefore, you should not drink or drink less sugary drinks
.
　　3.
Eat cooked food, don't eat too much raw or cold food
.
　　In summer, people often like to eat raw melons, fruits, seafood and other foods
.
It is worth noting that the summer temperature is high, and various germs and parasites are easy to multiply.
If you do not pay attention to dietary hygiene, especially eating unsanitary food at the "three noes" stalls, you are likely to get sick
.
　　Some people like to drink a large bowl of iced beer or iced beverages in a hot day.
This "irritating" cooling behavior will stimulate the spleen and stomach, affect the secretion of gastric juice and reduce appetite, causing indigestion, anorexia, Abdominal pain, diarrhea and other gastrointestinal diseases
.
In addition, although cold food can temporarily alleviate the hotness, after the oral cavity is stimulated by the cold, it is easy to cause the salivary glands, tongue taste nerves, and periodontal nerves to rapidly cool down, and sometimes even paralyzed, which can irritate the throat and cause adverse reactions such as pharyngitis or toothache
.
　　4.
Get enough sleep and don't stay up late at night
.
　　After the beginning of summer, it will get dark late and light up early, and people tend to go to bed late and wake up early, resulting in insufficient sleep and often "napping" during the day
.
According to changes in solar terms, the rules of life, adequate sleep
.
If possible, take a short nap at noon, especially for elderly people who need to take a nap to supplement sleep
.
Those who do not have the habit of taking a nap at noon can listen to music or close their eyes to keep their minds refreshed to ensure a full mental state and sufficient physical strength
