Once the body needs a large amount of oxygen consumption (such as long-term learning work vigorous exercise) )Oxygen supply will be seriously insufficient resulting in adverse reactions such as headache dizziness chest distress mental depression inattention memory loss insomnia which will not only affect learning and work but also cause many irreparable loss of health.
