HEALTH NOTES: This will shake you … too LITTLE salt can be bad for us
Health heads are constantly telling us to lower our salt intake, but new research suggests that having too little also carries health risks.
Doctors at the Royal Free Hospital in London found that too little salt in the body, over a long period of time, weakens the immune system, increasing the risk of infections.
Patients with Gitelman syndrome and Bartter syndrome, which cause excessive salt loss through the kidneys, were more likely than others to have recurrent fungal and urinary tract infections.
The authors of the study, published in the medical journal Nature Communications, explain that a lack of salt stops the production of a type of white blood cell called interleukin 17, which detects and destroys infections.

Holding hands soon after an argument can help couples end any disagreement quickly, research suggests.
Partners who held hands and stared at each other for three minutes after a heated discussion became less stressed and saw their heart rates normalize faster, the study found.
One theory is that touching hands increases the amount of oxytocin, the so-called hug hormone, which is linked to happy feelings.
The researchers, from the University of Amsterdam, suggest the technique may be useful in relationship therapy.
Leukemia Warnings We Ignore
Half of British adults would not seek help for telltale signs of blood cancer, according to a survey.
Research by the charity Leukemia Care found that half of the participants surveyed would not visit their GP with unusual bruising or bleeding – the most common signs of leukemia.
The survey of 2,000 people also found that three-quarters would not seek help for other symptoms, such as fever or night sweats, and that two in five would not talk to a doctor about feeling weak and breathless.
Zack Pemberton-Whiteley, director of patient advocacy at Leukemia Care, said, “If anyone is experiencing any of these symptoms, it’s always worth contacting a primary care physician and requesting a blood test.”
