Optimists are much less prone to heart disease.
Scientists from the Duke Clinical Research Institute and Columbia University analyzed the data of surveys that have been filled in by almost 2,400 patients with chronic angina and came to an interesting conclusion. It turns out that the patients who have an optimistic attitude toward life required hospital treatment 30-40% less often than those having a pessimistic attitude.
Positive mood reduces the level of adrenaline and cortisol — the hormones of anxiety and stress. It’s these that affect the increase in blood pressure, which in turn influence the development of cardiovascular diseases and heart attacks.
Fasting from time to time is good for the immune system.
A study held by scientists at the University of Southern California showed that fasting for 2-4 days helps to refresh the immune system. Over the duration of the experiment, volunteers fasted for several days in a row, every six months. During the days of fasting, their body started to use its own reserves of glucose, fat, and ketones and began to destroy a large number of leukocytes as well. As a result, their loss contributed to the renewal of the cells of the immune system.
Long fasting also decreased the level of hormones that are connected with aging and the appearance and progression of tumors, including cancer.
It’s worth mentioning that fasting is contraindicated in severe body weight deficiency, malignant tumors, active tuberculosis, heart rhythm disturbances, urolithiasis and cholelithiasis, stomach ulcers, and liver cirrhosis. Additionally, children and elderly people should abstain from long-term fasting, as well as women during pregnancy and lactation.
