Admit it, you had to send curses on the heads of manufacturers of canned food packed in glass containers with a screw cap? After that, the previously intractable lid, as if by magic, immediately unscrewed.
A new study by a team of scientists at Keele University in Staffordshire in England led by Dr. Richard Stevens found that cursing actually helps people increase muscle strength.
Psychologists conducted tests in which volunteers had to swear before starting intense exercise on a stationary bike or before squeezing an expander, which measured the strength of the hand. In both experiments, harsh swearing helped significantly improve performance over the pronunciation of neutral words.
In the first experiment, 29 volunteers with an average age of 21 worked on an exercise bike with the brakes applied for half a minute, repeating swearing or neutral words.
Scientists found that peak power increased by an average of 24 watts during curses.
The second experiment involved 52 participants of about the same age, taking tests on hand strength. Again, the volunteers were asked to swear or say a less emotionally charged neutral word while taking measurements.
Swearing increased the muscle strength of the hand by an average of 2.1 kilograms.
Previously, the same team of scientists conducted a study that showed that swearing increased the pain threshold. However, this is a well-known reaction to hitting one's fingers with a hammer.

Researchers then believed that a possible reason for this was the stimulation of the body's sympathetic nervous system - this system makes our heart beat wildly when we are in danger.
To the surprise of scientists, recent tests did not show an increase in heart rate and other expected changes, such as an increase in adrenaline levels associated with the response "fight or flight".
It seems that researchers have yet to understand the power of swearing and how it affects muscle strength.
