Indoor fitness is poor in lack of sunlight

Gyms, swimming pools, badminton halls... Nowadays in large and medium-sized cities, young and middle-aged people have become regular visitors to these sports venues. However, there are test results show that although the physical fitness function of indoor fitness family is very good, but many people's bone density does not meet the standard, and even suffer from osteoporosis, many of which are young people. Some experts said: “This is mainly due to the lack of outdoor activities in the sun. In fact, the fitness effects of outdoor sports are not substitutes for indoor sports.”

The reporter learned from the investigation that at present, urban white-collar workers either do not exercise or rely mainly on indoor sports, such as running, swimming, practicing yoga in the gym, and playing badminton and basketball indoors. Since it cannot be exposed to sunlight during exercise indoors, it has little effect on body skeletal exercise.

Mr. Wang’s recent medical examination at a large state-owned enterprise found that he had a low bone mineral density and he was only 33 years old. He is very puzzled about this: Generally only osteoporosis occurs in the elderly, how will this occur in his age? And he also often exercise at ordinary times, in the unit is the master of playing table tennis. For his doubts, the doctor revealed the reason.

The doctor told Mr. Wang that, according to common sense, osteoporosis should indeed be a common disease in the elderly population, but now it seems that there is a trend toward young people. Even some units found in the physical examination, the number of young people suffering from osteoporosis Older people have been surpassed, and many are young people under the age of 35. The usual amount of exercise for these young people is not small, and most people can stick to physical exercise. However, they all have a common feature. Sports venues are basically confined indoors and rarely exercise outdoors. This is the main reason for young people suffering from osteoporosis.

The fitness effects of outdoor sports are not replaced by indoor sports. Outdoor sports can allow the body to fully receive the sunlight, so that the body produces vitamin D, so that the bone density remains normal. Nowadays, many people have misunderstandings about fitness. They think that if they run on a treadmill, play badminton, table tennis, swimming, etc., they will produce better fitness results. This kind of thinking is actually one-sided and it also leads directly to some indoor activities. The fitness family is no longer willing to go outdoors for exercise. Therefore, doctors suggest that urban white-collar workers should still increase the amount of outdoor exercise in a timely manner, so as to fully enhance physical fitness.
