Healthy Sleep Improves Immunity

German researchers conducted an experiment in which volunteers were observed for two 24-hour sessions. During this time, the concentration of T-lymphocytes in their blood, which play an important role in the immune system, was measured. It turned out that the blood analysis results largely depended on the amount of sleep. People who slept at night had an improved ability of T-cells to migrate to lymph nodes. The crucial factors for such behavior were growth hormone and prolactin. These substances can be used in the future to stimulate the immune response of the body after vaccination.

Even a small amount of physical activity can help prevent stroke

Even a small amount of physical activity helps prevent stroke. Scientists analyzed the results of 15 surveys, in which a total of 752,050 adults participated - their health status was monitored on average for 10.5 years. The analysis showed that compared to a complete lack of physical activity, even a small amount of exercise reduces the risk of stroke by 18%, while intense exercise reduces it by 29%. Researchers concluded that even minor physical activity, such as slow walking, climbing stairs, and leisurely cycling, can help prevent stroke in the long term.

The Scent of Pheromones Accelerates Aging

The scent of pheromones accelerates aging. Scientists from New Zealand conducted an experiment on mice and found that males age faster and die when exposed to the attractive aroma of female pheromones. They placed the mice in a cage next to female mice and observed increased mortality among the males. It is believed that the inability to attract the possessor of an appealing scent causes constant stress in the individual, which accelerates the aging processes. Furthermore, scientists have suggested that this phenomenon may also occur in humans, which could explain why men have shorter lifespans compared to women.

Increased Hangover Symptoms Linked to COVID-19

Due to COVID-19, hangover symptoms may have worsened. Researchers have found several pieces of evidence supporting this theory. Those who have had COVID-19 for several months mostly complain about intensifying hangovers. Previously, they could drink and not suffer in the morning, but now hangovers occur after just one glass. The reason is that the illness has disrupted the blood-brain barrier, which helps prevent pathogenic microorganisms from entering. As a result, the brain becomes more susceptible to what is happening in the body.

Potential Heart Problems Associated with High Consumption of Sugar-free Coca-Cola

If you consume about 2 liters of sugar-free Coca-Cola per week, you may experience heart problems. For instance, a specific type of arrhythmia may develop. Scientists from China have established a correlation, indicating that the likelihood of developing the condition is 20% higher compared to those who do not drink as much Coca-Cola.

Foods that can disrupt your sleep

If you couldn't fall asleep at night, one of these dishes may be to blame: Spicy dishes and anything with tomatoes should not be eaten before bed as they can cause acid reflux; Burgers and pizzas with ketchup and tomato sauce fall into the same category; Ice cream and carbonated drinks increase sugar levels and prevent sleep; Milk also triggers processes in the stomach that interfere with sleep. A group of doctors has revealed this information.

Obesity surpasses hunger as a global health problem

Obesity has surpassed hunger on the list of global health problems. The number of people with clinically excess weight has exceeded one billion for the first time. The trend is most noticeable among teenagers - the obesity rate has quadrupled since 1990.

Signs of alcoholism

2-4 glasses of wine per week - the first sign of alcoholism and the stage of casual drinking. This was stated by an expert in addiction medicine. Another sign is when you realize that alcohol causes more harm than pleasure, but you continue to drink.

Regular cannabis use linked to increased risk of heart and vascular diseases

Regular cannabis use is associated with a risk of heart and vascular diseases. The main active compound in marijuana has hemodynamic effects, including tachycardia, vasodilation, and fluctuations in blood pressure, which can harm the body. Through a new study involving 434,104 respondents, scientists have found a connection between daily cannabis use and ischemic heart disease, myocardial infarction, and stroke, with the risk being proportional to the frequency of use.

Listening to Meditations During Sleep is Beneficial for the Heart

Listening to meditations during sleep has been found to be beneficial for the heart. Specialists decided to analyze the electrical activity of the heart. Sleeping participants were played audio recordings of human speech with different emotional tones. When listening to calm speech, the volunteers' heart rate slowed down. This means that the quality of their deep sleep improved, as well as the duration of this phase. The authors of the study are confident that their findings can help find a comprehensive approach to ensuring a healthier and more restful sleep and utilize them in the future.

Discovery of Three Classes of Natural Antibiotics in Tibetan Bacteria

The app monitors the user through the front camera, reads their expressions, body language, eye movements, head tilt, and determines whether the user is suffering from depression. It is said that the app works with 75% accuracy and can detect signs of the disorder even before the person notices it themselves.

Dogs Can Detect Parkinson's Disease with Nearly 90% Accuracy

Scientists have taught dogs to recognize Parkinson's disease by smell with an accuracy of almost 90%. This may be due to special substances emitted by human skin. Dogs can potentially be used to screen samples from individuals with early symptoms of Parkinson's disease to determine who will need further analysis and subsequent treatment. In the future, this could become an effective and affordable method of diagnosing the illness.

TV Viewing Can Cause Nighttime Bathroom Trips

Watching television may lead to nighttime bathroom trips. Chinese researchers analyzed data from a large-scale survey of people in the United States and found that 32% of them reported the need to wake up for a bathroom trip more than once a night. It turned out that the risk of experiencing symptoms was 48% higher for those who spent five or more hours per day watching television or videos, compared to those who watched for less than an hour. This could be related to fluid retention in the legs due to a sedentary lifestyle and the consumption of beverages often accompanying TV viewing.

Fried potatoes are harmful for brain function, say dietitians
