1, drinking water formula: water is the basic substance to maintain human metabolism and physiological functions. Children have a strong metabolism and need more water than adults.
The gastric mucosa of the elderly is usually damaged, glands atrophy or disappear, and it is easy to feel thirsty. Take water with you and replenish it in time. Drink 2000-2500 ml of water every day, otherwise problems such as blood viscosity and thrombosis will easily occur.
People who do strenuous exercise or work in high temperature environment should increase the amount of drinking water appropriately.
2, drinking formula:
Generally speaking, drinking low-alcohol liquor below 40 should not exceed 2 ounces; Medium-low alcohol liquor of 40-50 degrees, no more than 65438 0 Liang; Do not exceed 0.5 ounces of spirits above 50 degrees; The degree of wine is relatively low, but it can't exceed 3 Liang, otherwise it will burden organs such as the liver.
3, bone mineral density formula:
According to Hiroshi Haruno, a professor at Tottori University in Japan, the bone mineral density and the risk of osteoporosis can be estimated by weight and age. For example, a person who weighs 45 kilograms and is 70 years old has a risk index of (45-70)×0.2=-5, indicating that it is likely to be osteoporosis. It is suggested that people with moderate or severe risk go to the hospital for bone mineral density examination.
4. Exercise heart rate formula:
The state of heart rate during exercise helps to measure the intensity of exercise and prevent improper or excessive exercise.
For adults, when the actual heart rate reaches 70% of the highest heart rate, it belongs to high-intensity exercise; 55%-69% belong to moderate intensity exercise, and 40%-54% belong to low intensity exercise.
For the elderly, exercise does not need great intensity, but it can achieve the effect of exercise.
For example, if a 70-year-old man does aerobic exercise, his heart rate should be controlled at 170-70= 100 beats/minute.
The elderly can be controlled at (170- age) ×0.9 for safety.
5, body fat rate formula:
Body fat percentage, also known as body fat percentage, reflects the fat content in the human body. The body fat rate of normal adults is 17%- 23% for men and 20%-27% for women.
6, happiness formula:
Samuelson, a Nobel laureate in economics and an American economist, put forward this happiness formula, from which three possibilities can be deduced:
When desire is constant, happiness is directly proportional to matter.
Under the condition of constant material, happiness is inversely proportional to desire
When material and desire increase together, happiness will increase if the growth rate of material exceeds the growth rate of desire; If the growth rate of material is lower than that of desire, happiness will decline.
The main reasons for the decline of modern people's happiness are: love to keep up with the joneses, lack of spiritual goals, failure to find a beautiful side, lack of dedication, dissatisfaction, great pressure and anxiety.
Happiness is not earth-shattering and out of reach, but a beautiful feeling, a help to others, and a pleasant feeling of living in the present.
If you want to improve your happiness, you might as well start with small things. For example, reading a book when you are bored, watching a play with friends, and preparing a food for stray cats on the roadside are all shortcuts to enhance happiness.
7. Efficiency formula:
Many people maintain high-intensity working conditions for a long time, but high intensity does not mean high efficiency. The most efficient people are usually not the most "diligent" people.
Many people think that if they spend more time, they will naturally get more results, which will lead to a vicious circle of low efficiency and consumption.
When the work efficiency is reduced and the working hours are too long, the human body will feel extremely tired. It is suggested to take a proper rest for 20-30 minutes, put aside your work first, take a hot bath at home, have a delicious dinner and have a good sleep, which can recharge your body and improve your efficiency.
Before work, you should determine your priorities and make a good time plan. According to the biological clock, working hours can be divided into golden time with the highest efficiency, silver time with the second efficiency, ordinary bronze time and stone time with low efficiency.
According to different time periods, handle appropriate work and maximize work efficiency.
