People who wake up and sleep late eat more
People who sleep and wake up later consume more calories at night, more fast food, and fewer fruits and vegetables, according to research done at Northwestern Feinberg University of Medicine. The study is one of the first in the United States to explore the relationship between sleep, eating behavior and body mass index.
The researchers brought together 51 people (23 who slept late and 28 slept at recommended times), all of whom were of medium age of 30 years. The first group would sleep around 3.45 in the morning, wake up at 10.45, have breakfast at noon, have lunch at 2.30 pm, have dinner at 8:15 pm and have a final meal at 10:00 p.m
People on the normal shift would wake up on average at 8:00 a.m. , had breakfast at 9:00 a.m., ate at 1:00 a.m., ate at 7:00 p.m., had a snack at 8.30 p.m., and slept at around 10.30 p.m.
Participants recorded everything they ate at certain times and used a wrist actigraph, a device that monitors the sleep and activity cycles. At the end of the study, researchers found that people on the night shift consumed 248 more calories a day, twice as fast as food, half of fruits and vegetables, and even more soda than those who slept and woke up earlier. > Researchers say that people who sleep and wake up later have a tendency to consume more calorie and less healthy foods at night, and that this excessive amount of calories per day can result in up to two pounds more per month, if not are balanced with physical activity.
The study therefore shows that it is not only what you eat that is important but also the time to eat. And this is directly linked to your sleep schedules. The results may be relevant to people who are not very successful at weight loss and night shift workers who eat at the wrong time of day.
Good sleep is key
Among all the problems that can be caused by sleep deprivation, hormonal disorders are among the most important. People who sleep less than necessary are hampering the body's task of performing some processes that are critical to balancing all the functions that the body needs to play to be healthy.
Growth, for example, is especially affected when sleep is short or of poor quality. It is during sleep that the greater amount of production of the hormone GH occurs, that is responsible for the development. This peak occurs during the first phase of deep sleep, less than an hour after the start of the rest period.
Leptin, which controls the individual's satiety, is released in large quantities during sleep. Thus, a person who has difficulty sleeping well will be more prone to becoming obese, due to the absence of satiety during the day and increased anxiety in daily activities.
Doctor and sleep researcher Fernanda Haddad says that women are more likely to have hormonal problems as a result of poor sleep, mainly due to menopause, which usually begins to show symptoms between 45 and 50.
The danger of hormonal dysfunctions due to sleep is increasing. Today's society demands from the individual an almost integral commitment to work and is causing many people to think that they can adapt the body to fewer and fewer hours of sleep.
Among the characteristics associated with early aging is the absence of effective sleep. Insomniacs and people who force unnatural awakening very often at times when the body is not yet ready are diminishing their own intellectual capacity as the lapses of attention become longer and more mundane. Thus, exaggerating work and neglecting sleep tends to worsen human performance on corporate tasks, rather than improving.
The current system already checks cases of acute flaccid paralysis in 177 of the 194 WHO member countries, differentiating polio from non-polio cases, including Guillain-Barré syndrome. According to researcher Nirmal Kandel, identifying regions with large numbers of cases with this disease can help detect which sites have already been hit by the Zika virus, evaluating how the virus has spread.
The possibility of curing a gastritis is essentially linked to finding the cause of gastritis and treating it. Gastritis is caused mainly by the bacterium Helicobacter pylori (especially anti-inflammatory drugs), alcohol, drugs, other infectious agents, radiation, metabolic stress (burns and major surgeries, for example), allergies, autoimmune diseases, etc.
