- and what can we do when we cannot sleep?

Sleep disorders are common in the western world, and many people find that the problem gets worse when we shift to daylight saving and get an extra hour of light in the evening. It can be difficult to fall asleep when it is still light outside, and this may even be a stress factor for those people who need to get up early the following day. Getting just one hour less of sleep can affect your concentration, mood, heart function, fertility, and a number of other things. Nevertheless, the sleep hormone, melatonin, combined with some practical advice may work wonders for your sleep, and proper sleep is of great importance to your health.

Medical science has claimed for decades that elevated cholesterol levels pose a health threat, especially if you have too much of the so-called “bad” cholesterol – or LDL (Low-Density Lipoprotein). However, a team of international experts is now arguing that this theory is exaggerated. In fact, the experts specifically advise against taking cholesterol-lowering statins. Meanwhile, science is focused on how to improve the safety of statins by combining them with supplements of coenzyme Q10.

Selenium is crucial for your thyroid function, immune system, cardiovascular system, and even for preventing cancer. Fish and shellfish are among the best selenium sources, but even 200 grams of fish and shellfish five days a week won’t do the trick, according to a Danish selenium study. What makes it even more difficult to obtain optimal amounts of this nutrient is that the agricultural soil in large parts of Europe is stripped of vital nutrients like selenium. Margaret P. Rayman, one of Europe’s leading experts on selenium, says that there is a direct link between the decreasing selenium intake and the increasing rate of cancers, rheumatism, infertility, and numerous other health problems. The question is, how do we humans get enough selenium?

According to a Japanese study, some people with Parkinson’s disease may find that coenzyme Q10 helps to relieve their symptoms. Q10 occurs in two forms, both of which have vital functions, but the scientists observed that only the one form had a positive effect on Parkinson’s disease. Nonetheless, when supplementing with Q10, both forms are equally good. What matters is that the active compound can be absorbed. Once it has been absorbed, the body can shift from one form to the other, a process that also requires selenium.

A new study shows that patients with early stages of Parkinson’s disease may benefit from getting more vitamin B3 from their diet or from supplements. This is because the nutrient supports cellular energy turnover and helps repair damaged nerve cell DNA. It is vital to get sufficient amounts of vitamin B3 as part of the prevention of the much-dreaded disease.

- which may be caused by lack of melatonin and the presence of toxic substances in the brain

Night owls stay up late in the evening and get up late in the morning, and they risk depression, according to a new study. In fact, there seems to be a link between the increasing number of people with disturbed 24-hour rhythm who expose themselves to blue light from computer screens and other devices, and who become depressed. Lack of sleep at night and low levels of the hormone melatonin are a burden to the brain and nervous system in several different ways.

Asthma is the leading disease among children and adolescents in the Western world, and the rate has been going up for the past 20 years. A new Danish study that is published in the New England Journal of Medicine shows that pregnant women who take supplements of fish oil are much less likely to give birth to children that develop asthma later on. The question is how much fish oil it takes to obtain the positive effect.

Fragile bones, also known as osteoporosis, is an insidious scourge. Science has its eyes on calcium and vitamin D, but osteoporosis may also be a result of getting too little vitamin K2 and magnesium, both of which are nutrients that must be properly balanced with calcium. If not, calcium may do more harm than good. Carbonated beverages, stimulants, and medicine (including statins) may also interfere with the bone-building processes. Therefore, strong bones require a lot more than calcium, and it is also important to remember daily, bone-challenging exercise.

Vitamin C is extremely important for the brain’s blood vessels, nerve cells, neurotransmitters, and connective tissue. An estimated 10 percent of the adult population is vitamin C deficient without specific symptoms. According to a scientific article in the Danish journal Aktuel Videnskab, vitamin C deficiency during pregnancy may harm brain development in the fetus.
