■ Cold Sleep: Scientists have proven that sleeping in a cool room (at a temperature of 17℃) can help people stay youthful. Researchers at a German university first confirmed this. If an apple is refrigerated, it can stay fresh for a longer period of time, and the same applies to humans and animals. The higher the temperature, the faster the metabolic processes in the body, which leads to premature aging. Therefore, doctors recommend that the room temperature should not exceed 17℃ when sleeping.
■ Mild Hunger: Consuming 6,000 kilojoules of calories per day is enough to keep the body cells active and facilitate rapid metabolism. Professor Wulfert from the University of Los Angeles believes that this can help people live up to 120 years old. Professor Wulfert conducted experiments on mice: mice that ate very little had a lifespan twice as long as their peers who ate as much as they wanted. He believes that by using this "youth elixir," people can live up to 120 years old and maintain vitality and youthfulness.
■ Adequate Sleep: Middle-aged and elderly people should learn to live a regular life, going to bed and waking up on time, and ensuring 7 to 8 hours of sleep every day.
■ Regular Exercise: After the age of 40, most people reduce their physical activity by 30% to 50%, which often marks the beginning of the decline in various organs of the body. If you exercise for 30 minutes every day, there will be significant improvements in your physical condition.
■ Keep Smiling: "A smile brings harmony and achievements, and brings benefits to the body." Smiling frequently is a sign of maturity and friendliness, which is beneficial for interpersonal relationships, life, and work. Moderate laughter can maintain and promote the relative balance of bodily functions, and it has the effect of uplifting the spirit, enhancing intelligence and tranquility, and strengthening the body.
■ Virtue for Longevity: Ancient people emphasized the importance of cultivating virtue for health, and modern medical psychologists have also revealed the reasons behind "corruption leads to early death." Strengthening moral cultivation is not only beneficial to human health but also important for promoting social civilization.
■ Love for Youthfulness: Love is more effective than any beauty method, and intimacy, tenderness, and sexual activity between spouses are the elixir of health and longevity. Therefore, elderly people should not easily give up or terminate sexual activity but should maintain moderate and regular sexual activity according to their own conditions.
■ Scientific Supplementation: Increase Nucleic Acids: Scientific research has proven that nucleic acids are the most important substance in the composition of biological cells. In human tissues, nucleic acids have various functions in terms of inheritance, catalysis, storage, energy supply, and immune enhancement. Adequate supply of nucleic acids can effectively delay the aging process and prevent the occurrence of various diseases.
■ Eat Bread Crust: When baking flour, a substance accumulates on the bread crust. This not only makes the bread crust black and sweet but also activates enzymes that inhibit free radicals, which can fight cancer and delay aging.
