Why wrapping your stomach is unsafe and ineffective

I thought this archaism have had it’s day, but I just saw a few posts that propagsndize cardio when belly is wrapped with plastic wrap.
So why it’s unsafe?
💥It can contain PVC and BPA which can cause can cause birth defects, skin diseases, cancer, liver and spleen diseases. Heating plastic increases the chances of releasing chemicals into your body.
💥It leads to water and microelements loss. There was some causes of sudden deaths this way (hypo-natrimia&kalemia)
💥Overheating can leads to some organs and systems disfunction. Columbia Health reports that in 1997, three wrestlers died after exercising in «sweat suits».
💥Profuse sweating can lead to blood composition changes, reducing blood volume and sending less oxygen to the cells. Weakness, dizziness, confusion, coma and even death may occure.
💥Why it’s ineffective?
💥It won’t lead to fat loss. You can loose few pounds of water (with important microelements) while you sweating, but it will return as soon as you drink water (without these microelements).
💥Overheating leads to very high heart rate. But according to studies the best way to lose fat is long (40min-2hrs) cardio with low 120-140 heart rate.
💥Most people who report satisfaction with the results of the body wrap also kept a diet and work out four or five times a week.
💥The only proven way to lose weight is to eat less calories than you burn.
