Masks in the daytime can cause a heart attack.
To revive a heart attack victim at daytime, massage the pulmonary vein.
Masks in the evening can prevent a heart attack.
To revive a heart attack victim at night, massage the pulmonary artery.

“So people who wear masks should get night jobs.”
Ray Peat (“Protective CO2 and aging, 2011) wrote …
“Since queen bees and mole rats live in the dark, I think their high carbon dioxide compensates for the lack of light. (Both light and CO2 help to maintain oxidative metabolism and inhibit lactic acid formation.) Mole rats are believed to sleep very little. During the night, normal people tolerate more CO2, and so breathe less, especially near morning, with increased active dreaming sleep.”
According to The Journal of the American Medical Association (1922) …
“Experiments on the effects of breathing carbon dioxide have been conducted at the Pittsburgh station of the U.S. Bureau of Mines. It was found that about 2 percent of carbon dioxide in oxygen produced a slight increase in lung ventilation but no subjective symptoms; 5 percent in oxygen caused an increase in lung ventilation of about 100 percent, but no other signs or symptoms; 7.2 percent produced about 200 percent increase in lung ventilation; moderate perspiration and a slight fullness in the head were experienced after breathing this mixture for ten minutes; 9 to 10 percent produced about 300 percent increase in lung ventilation, and the subject complained of frontal headaches and was dizzy and perspiring at the end of ten minutes. About 9 percent of carbon dioxide in oxygen was breathed by some of the subjects for as long as forty-five minutes, but the breathing was very laborious, and dizziness, headache, and perspiration were marked. In fact, to have done any work while breathing this mixture would have been extremely difficult.”
