Don't eat overnight food.
Old people usually come from hard times, so most of them are frugal. Moreover, because of the growth of age, the appetite decreases, so many times, overnight dishes will be left until the evening, then put in the refrigerator, and the next morning they will still be eaten hot. Although there is no problem in many cases, after all, most families in China do this, but what if they encounter spoiled food? If you really have a stomachache, the physical quality of the elderly is not better than that of the young, so you should cook less at night, eat something fresh in the morning, and don't eat overnight meals if you can.
Be sure to drink more warm water.
Old people can make some tea in their leisure time. When I was young, my uncles and aunts in the village were thirsty and drank water directly from the water tank with a ladle. It seems to quench my thirst. In fact, the elderly should try to drink less raw water or cold water. The gastrointestinal function is also getting worse, and drinking cold water is easy to be stimulated. So you can usually prepare a bottle, then make some tea and drink a few cups when you are thirsty. Not only can you leave a fragrant mouth, but you can also clear your intestines and have the effect of health preservation.
Blow less air conditioning and get close to nature.
Old people should try not to stay in air-conditioned rooms for a long time. Although children are filial and afraid of their parents being hot in summer, sometimes the cold air of air conditioner will be inhaled into the body, leading to colds and gastrointestinal discomfort. Therefore, the elderly should sweat a little, and then go out for exercise in the morning and evening to get close to nature. Tai Chi can also be passed around. Proper sweating can effectively eliminate the cold in the body.
Finally, the elderly should eat more fruits and vegetables, eat less greasy things and eat more fish appropriately. May the elderly at home live a long and healthy life!
