The most comprehensive collection of life and health knowledge in history

This article collects over 500 pieces of common sense: 45 medical and health tips, the effects of vitamins, 100 women's health facts, 60 daily life tips, 43 health tips, 53 folk tips, 10 household cleaning secrets, and 126 life skills.
　　I. Medical and Health Tips
　　1. Normal Heart Rate: 75 beats per minute. A healthy adult's heart rate at rest averages 75 beats per minute. The normal range is 60-100 beats per minute. A resting heart rate of over 100 beats per minute is considered tachycardia, while a heart rate below 60 beats per minute is considered bradycardia. Heart rate can vary depending on age, gender, and other factors. For example, for every 1°C increase in body temperature, the heart rate can increase by 12-20 beats per minute. Women's heart rates are slightly faster than men's, and athletes' heart rates are slower. fang12130
　　2. Normal body temperature: 36.3°C-37.2°C (oral measurement).
　　Oral, rectal, and axillary temperatures are commonly used clinically to represent body temperature. The normal range for the oral measurement (holding the temperature under the tongue for 5 minutes) is 36.3°C-37.2°C; the axillary measurement (holding the temperature under the armpit for 5 minutes) is 36°C-37°C; and the rectal measurement (lubricated with a thermometer and inserted into the anus for 5 minutes) is 36.5°C-37.7°C. Throughout the day, human body temperature fluctuates periodically, generally lowest between 2:00 and 6:00 AM and highest between 1:00 PM and 6:00 PM, but the fluctuation generally does not exceed 1°C. A temperature above 37.3°C is considered normal.
　　3. Hemoglobin (HbB): Adult males (120-160 g/L), adult females (110-150 g/L).
　　Clinically, hemoglobin levels are used to diagnose anemia. A normal adult hemoglobin level of 90-110 g/L is considered mild anemia; 60-90 g/L is moderate anemia; and 30-60 g/L is severe anemia. White blood cell count (WBC): 4-10*(10 to the power of 9) cells/L
　　A WBC count greater than 10*(10 to the power of 9) cells/L is considered leukocytosis, while a count less than 10*(10 to the power of 9) cells/L is considered leukopenia. Generally speaking, WBC levels may increase during acute bacterial infection or inflammation, while they may decrease during viral infections. Colds and fevers can be caused by both viral and bacterial infections. To determine the cause and guide clinical medication, doctors usually order a complete blood count.
　　5. Platelet count (PLT): 100-300*(10 to the power of 9) cells/L
　　Platelets play a role in maintaining the integrity of blood vessel walls. When the platelet count drops below 50*(10 to the power of 9) cells/L, especially as low as 30*(10 to the power of 9) cells/L, bleeding may occur, and petechiae and ecchymoses may appear on the skin. People with normal platelet counts who frequently experience bruises on their skin should not be overly concerned. Besides platelet counts, factors related to blood vessel walls, coagulation, and other physiological factors can also contribute to bruises. Consult a hematologist to determine the cause.
　　6. Urine Volume: 1000-2000 ml/24 hours.
　　A 24-hour urine volume >2500 ml is considered polyuria. Physiological polyuria occurs after excessive drinking or the use of diuretics. Pathological polyuria occurs in conditions such as diabetes, diabetes insipidus, and renal tubular diseases.
　　7. 24-Hour Urine Volume: Nocturnal Urine Volume: 500 ml
　　Nocturnal urine volume refers to the total urine volume from 8 PM to 8 AM, typically 500 ml, with 2-3 urinations. If the volume of nocturnal urine exceeds the volume of daytime urine, and the frequency of urination increases significantly, it is called nocturia. Physiological nocturia is associated with excessive drinking before bed; pathological nocturia is often a sign of impaired renal concentrating function and an early sign of renal impairment. Besides renal impairment, nocturia can also be caused by prostate hyperplasia in men, uterine prolapse in elderly women, urinary tract infections, diabetes, and mental stress.
　　8. Normal urine red blood cell count (RBC): 0-3/high-power field.
　　Urine RBC count >3/high-power field is considered microscopic hematuria.
　　Normal urine white blood cell count (WBC): 5/high-power field is considered microscopic pyuria. A large number of WBCs in urine is often a sign of a urinary tract infection, such as pyelonephritis, renal tuberculosis, cystitis, or a urinary tract infection.
　　10. Sperm survival time: 72 hours. Ovum survival time: 24 hours.
　　The problem with safe period contraception is that, besides mistaking the ovulation date, there's another factor that shouldn't be ignored: since sperm can survive in a woman's body for three days, even if it's not her ovulation day, as long as she's within her fertile period (four days before to two days after ovulation), she's still very likely to conceive.
　　11. Two major blood group systems: ABO and Rh .
　　The ABO blood group system divides blood into four types: A, B, AB, and O. The Rh blood group system divides blood into two types: Rh-positive and Rh-negative. Among Caucasians, 85% have Rh-positive blood, and 15% have Rh-negative blood. In the United States, 99% of the population has Rh-positive blood, and Rh-negative is considered a rare blood type.
　　AA: A, O; AB: A, B, O, AB; A-AB: A, B, AB; AO: A, O;
　　BB: B, O; B-AB: A, B, AB; BO: B, O; O-AB: A, B;
　　OO: O; AB-AB: A, B, AB. If one partner is type AB, the baby cannot be type O. If both partners are type O, the baby can only be type O.
　　12. Body Mass Index (BMI) = Weight (kg) /Height (m) squared: 18.5-23.9 is considered normal.
　　13. Optimal Weight Loss Rate: 1-2 kg per month
　　. Overweight individuals should gradually lose weight under a doctor's guidance. Rapid or drastic weight loss can lead to adverse reactions such as weight regain, anorexia, anemia, malnutrition, menstrual irregularities, hair loss, memory loss, and osteoporosis.
　　14. Waist Circumference: Men ≥ 90 cm, women ≥ 80 cm are considered abdominal obesity
　　. Waist circumference is an indicator of abdominal fat accumulation and abdominal obesity (also known as "apple-shaped obesity"). Abdominal obesity is currently considered a significant risk factor for coronary heart disease and metabolic syndrome. If your BMI is not yet obese, but your waist circumference is excessive, you have abdominal obesity. Abdominal obesity is more dangerous than general obesity and is more susceptible to coronary heart disease and diabetes.
　　15. Obesity Signs: Gaining 1.5 kg in a Month
　　Identifying weight gain at the very beginning and taking weight loss measures often yield significant results. The following symptoms often indicate a trend toward weight gain: shortness of breath after even the slightest exertion, fatigue, frequent sweating, and pain in the lower back, hips, and knees.
　　16. Blood Pressure: When normal, systolic blood pressure. Diabetes diagnostic criteria: Fasting blood sugar > 7.0 mmol/L and/or 2-hour postprandial blood sugar > 11.1 mmol/L.
