After struggling to get enough sleep from Monday to Friday, lying down during the weekend may seem like the best way to get some much-needed rest.
A range of studies have shown that a few extra hours of sleep in bed over the weekend is unlikely to make up for the sleep debt accumulated during the week, according to sleep and circadian rhythm expert Professor Russell Foster.
And a group of studies show that even sleeping 10 hours a night during the weekend will not restore your cognitive ability to its speed, but rather this may lead to disrupting the internal clock of the body, which increases the difficulty of sleeping during the night, according to the “Daily Mail”.
Professor Foster says a person is not getting enough sleep if they struggle to perform “at their peak” during the day.
A person needs eight hours of sleep per night on average. But he says six to ten and a half hours is a “healthy range.”
But those who regularly feel tired, irritable, irritable, and need sugary or caffeinated drinks may need more time in bed.
However, making up for lost hours of sleep over the weekend by sleeping in is not the best way to achieve this, as sleeping on the weekend can have an indirect effect on your body clock if it prevents you from going outdoors in the morning. As Professor Foster says.
Foster explains that exposure to morning light helps the body enter the pattern of waking up early and going to bed early.
Foster suggests that those who suffer from sleep deprivation go to sleep in the early evening and stick to their usual routine.
He added: “You can sleep a lot on the weekends, but make sure you go to bed early instead of staying in bed later.”
Nutrition Expert : Unexpected benefits of eggshells for human health
Eggshells contain important mineral elements that make them useful in preventing osteoporosis.
Dr. Maryat Mukhina, a Russian nutrition expert, explains: “Eggshells contain the elements phosphorus, calcium, potassium, iron, and magnesium in an organic state, which facilitates their absorption. That is, eggshells are beneficial for the musculoskeletal system and bones. Because with age, especially women, the risk of osteoporosis increases. Therefore, Calcium must be added to the diet constantly in order to maintain bone strength and prevent fractures.
On the other hand, the doctor warns of the danger of the presence of salmonella and Escherichia coli bacteria in the eggshell. Therefore, it must be washed well, dried, heated in the oven, and then ground before using it. You can also add lemon juice to eggshells and take a teaspoon a day.
Fitness : What are the cases in which taking Viagra is really not safe?
Research on the little blue pill (Viagra) reveals uses far beyond its known function.
Back when the drug was first developed, sildenafil (now known by the brand name “Viagra”) was originally designed to treat cardiovascular problems.
But instead of expanding the blood vessels in the heart, its effect emerged in another area of the body in men, which contributed to enhancing the erection.
This led to an expansion of Viagra production, doubling profits to more than a billion dollars annually.
In 2005, sildenafil under the name Revatio was approved to treat pulmonary arterial hypertension, a condition that causes high blood pressure in the lungs.
But one study, conducted in 2013, looked at sildenafil’s potential in a medical area that is often “overlooked.”
Viagra and menstrual pain
Menstrual pain, or dysmenorrhea, can be extremely painful and debilitating, leaving the patient unable to carry out her usual activities.
There is no real cure for this problem with women relying on over-the-counter painkillers and hot water bottles every month.
However, researchers from Croatia and the United States revealed that sildenafil can help relieve dysmenorrhea for hours.
In a study published in the journal Human Reproduction, researchers examined the effects of sildenafil on 25 women suffering from moderate to severe menstrual pain.
They found that sildenafil relieved pain better than a placebo, and “significantly” reduced participants’ uterine artery pulsatility index – an indicator of menstrual pain – after two hours.
Is it safe to take Viagra to treat menstrual pain?
While this study suggests that it may be safe to use Viagra pills to relieve menstrual pain, more research is needed on this topic.
In this regard, Dr. Susanna Unsworth, a gynecologist and women’s health expert at INTIMINA, said: “Theoretically, the mechanism of action of sildenafil could certainly provide a way to relieve pain symptoms by improving blood flow, along with increasing relaxation of the muscular wall of the uterus. However, based on this study alone, I do not currently consider it an option for women with menstrual pain because there is not enough evidence to show benefit, and there has been no discussion of any associated side effects. The treatment is not currently licensed for use in this way, to be sure. Wider testing is required before its use can be recommended.”
The following are cases in which taking Viagra is unsafe:
• Cases of allergic reaction to “sildenafil” or any other drug.
• Taking medications called nitrates to treat chest pain (angina).
• a serious heart or liver problem.
• Recently had a stroke, heart attack or heart problem.
• Reduction of Blood pressure.
• A rare genetic eye disease, such as retinitis pigmentosa.
• Sickle cell anemia (a defect in red blood cells), leukemia or multiple myeloma.
• Deformity of the penis.
• Stomach ulcer.
• Bleeding problem such as hemophilia.
