Factors affecting life span

The length of a person's life is influenced by many factors. A long and healthy life is a good wish that people always look forward to. However, diet, daily habits, emotions, etc. can affect the length of life. What factors are related to human life expectancy?

Heredity affects life expectancy

Genetic factors are the innate factors that determine the length of life. Among the nearly 100,000 genes in the human body, there are genes that can determine the length of life or the aging process. They are telomeres, reproductive genes, aging genes and apoptosis genes that affect cell replication.

Emotion affects life span

Emotional factors are extrinsic determinants of longevity. People who are emotionally optimistic live longer, while those who are often depressed and irritable live shorter. An optimistic person can have a positive effect on the nervous system, while a bad mood can affect normal neurological regulation and body metabolism, leading to premature aging.

Nutrition affects life expectancy

Adequate and balanced nutrition can also help extend life expectancy. Proper nutrition in time not to be partial, not to be picky, not to be taboo, nutrient supplementation complete, with scientific, appropriate ratio. Generally speaking, a day of cereals should be consumed 300 grams to 500 grams, fruits and vegetables 400 to 500 grams, fish, meat, poultry, eggs about 200 grams, 100 grams of milk, fats and oils not more than 25 grams is appropriate.

Exercise can also affect the length of life. People who often do aerobic exercise have good blood circulation, while those who do not exercise much have less blood supply to the brain, and are prone to brain atrophy, memory loss and so on. Proper brain and physical exercise can help exercise the brain and extend life.

Disease affects life expectancy

Disease also has a huge impact on life expectancy. Currently, many middle-aged and elderly people die not from natural causes but from diseases. Common diseases among the elderly include cardiovascular disease, hypertension, diabetes, arthritis, etc. Many people also suffer from multiple diseases at the same time.

Habits affect life expectancy

Life consists of trivial things, but in this chaos has its own rules, if it is often irregular living, diet, lack of sleep, uneven work and rest, etc. will destroy the body's biological clock, and lead to metabolic disorders in the body, accelerating the process of death.

The environment affects life expectancy

The environment also has a certain influence on the life expectancy of people. In life, the environment is always directly or indirectly affect the aging of the human body, such as polluted air, rapid changes in temperature, noise will accelerate the aging of cells, so that people accelerate the death.
