Long working hours increase heart disease risk – Study

-



It has been revealed that the more hours people work, the greater the risk of their contacting heart disease. This is the result of a study published in the Journal of Occupational and Environmental Medicine.
Several observational studies have found an association of long work hours with an increased risk for cardiovascular illness.
Cardiovascular disease generally refers to conditions that involve narrowed or blocked blood vessels that can lead to a heart attack, chest pain (angina) or stroke.
Other heart conditions, such as those that affect the heart’s muscle, valves or rhythm, also are considered forms of heart disease. Now a new retrospective analysis has found that there is a dose-response relationship: more hours, more risk. Researchers began following 1,926 men and women in 1986, tracking their health and work history through 2011.
Over the course of the study 822 were given diagnoses of cardiovascular disease. After adjusting for age, sex, income and other factors, they found that for each additional hour of work per week over 10 years, there was a one per cent increase in the risk for heart disease. Compared with working 45 hours a week, working 55 hours increased the risk by 16 per cent, 60 hours by 35 per cent, 65 hours by 52 per cent, and 70 hours by 74 per cent.
Working 75 hours or more doubled the risk for a cardiovascular problem — angina, coronary heart disease, hypertension, stroke or heart attack.
Still, the lead author, Sadie H. Conway, an assistant professor at the University Of Texas School Of Public Health in the United States (U.S) does not recommend that anyone alter work hours based on her study.

Healthy diet for the rainy season

Along with the showers comes the risk of various diseases like food poisoning, diarrhoea, dysentery and cholera. Again, in rainy season, digestion is generally weak. Therefore, you should eat less. It is also essential to fast once a week or fortnight. People eat some incorrect food during this time and fall sick. To protect your health, follow this dietary guideline: •Avoid heavy, salty food, as it promotes water retention and bloating. It is better to have medium or low salt food •Eat foods which are drying in nature, the most popular being corn, and oats, among others. Eating watery foods like rice and watermelon creates swelling in the body •Maintain the general hygiene while eating out and definitely avoid roadside vendors, as very few people have the high immunity to handle the bacterial overload at such places •The milk is the better diet in this season. Drink butter milk, as it improves digestion. Oily food should be taken in less quantity •Eat li

When fibroid co-exists with pregnancy

                        Dr. Samuel Adebayo Uterine fibroid, also known as Leiomyoma, is a benign (non-cancerous) tumour of the uterus (womb). Fibroids are the most common benign tumours in females and they occur during the reproductive years. They occur in up to 50 per cent of women. The exact cause of this tumour is unknown; but some factors are associated with increased chance of developing uterine fibroid. A family history is a factor. History of fibroid developing in women of the same family or race plays a role in a woman’s life. African women have between two and three times chances of developing fibroid than white women. Also, African women develop fibroid at a younger age, usually in their 20s and above, unlike white or caucasian women where fibroid may occur in their 30s or 40s. No pregnancy or low pregnancy rate increases the risk, just as early onset of menses may also increase the risk of developing uterine fibroid. Obesity, alcohol consumption, and hypertension may

Nigeria’s oldest domestic carrier Aero Contractors has just suspended scheduled flight services with effect from today September 1, 2016 but the Nigerian Civil Aviation Authority (NCAA) has dismissed claims that some airlines in Nigeria were shutting operations insisting that the airlines in question merely suspended scheduled flights temporarily as a safety measure. While explaining that Aero Contractors still operates charter services, the Director General of NCAA; Capt. Muhtar Usman Says the airlines were merely embarking on a temporarily suspension of flights to overhaul and strengthen their operations. He explained that “One of the airlines, Aero Contractors Ltd., at present has only one serviceable aircraft. “This is in contradiction to the Nigerian Civil Aviation Regulations which stipulates that no airlines operator shall carry out schedule commercial operation with only one aircraft. “The minimum acceptable number is three aircraft” Capt Muhtar furthe
