Is it useful to air dry sweatshirts on the front or back

It is recommended to air dry the back of the sweatshirt to protect the fabric coating and extend its service life. Sweat inducing clothing promotes sweating through its airtightness, but the weight loss effect mainly comes from water loss rather than fat consumption.

Sweat jackets are usually made of polyester fiber with constant drying material, and drying on the back can prevent direct sunlight from aging the outer waterproof film. The inner moisture absorbing coating is prone to peeling off after prolonged exposure to sunlight, while hanging on the back allows moisture to evaporate evenly from the inside out, reducing the odor caused by sweat residue. After exercise, the clothing should be flipped inside and outside in a timely manner, hung in a ventilated and cool place, and avoid high temperature drying or twisting with force. Some high-end sweatshirts may indicate drying requirements on the label, and specific product instructions should be followed for operation. The principle of action of a sweatshirt is to block sweat evaporation through a waterproof layer, causing the body surface temperature to rise and increasing sweating volume. Wearing exercise for a short period of time can indeed increase sweating, but the main excretion is water rather than fat, and weight loss is a temporary dehydration phenomenon. Continuous high temperature environment may cause dehydration or electrolyte imbalance, and it is not recommended to wear it continuously for more than 30 minutes. After exercise, it is necessary to replenish water in a timely manner, and patients with cardiovascular diseases should avoid using it. If pursuing long-term weight loss effects, it is still necessary to combine aerobic exercise with dietary control.

Daily use of sweatshirts should pay attention to controlling the exercise duration within 20-30 minutes, cleaning it promptly after exercise, and drying it on the back. Choosing styles with breathable mesh design can reduce stuffiness, and paired with heart rate monitoring ensures moderate exercise intensity. People who want to lose weight are recommended to use sweatshirts as an auxiliary tool, combined with jogging, skipping rope and other exercises, while ensuring a daily intake of 2000 milliliters of water to avoid excessive dependence on sweating and weight loss effects.
