Jan 4: A recent study conducted by the researches at the University of Chicago has shed light on the influence of sleep on diabetes. According to the research three nights of bad sleep will reduce the body’s ability to process glucose and will pave way for rise in the glucose level. Three consecutive days of less sleep will minimise the glucose tolerance level of young healthy adults this will be greater than the effect created by gaining 20 to 30 pounds.
Ability of our body to process glucose will vary according to the chronic sleep deprivation. The poor sleeping habits in the elderly and obese play a vital role in the progress of diabetes. Deep sleep or slow wave sleep is considered as the most effective form of relaxing and is necessary for retaining mental clarity. This is the first study of its kind that connected the significance of sleep and physical well being.
While commenting on the results Eve Van Cauter the author of the study opined that: “Previous studies from our lab have demonstrated many link between chronic or partial sleep deprivations, changes in appetite, metabolic abnormalities, obesity, and diabetes risk. The new study adds more value to the previous studies and it also hint that the poor sleep is strongly associated with the aging.”
As part of the research nine lean and healthy people were included as the samples. They are aged between 20 and 31 and are subjected to spend five nights in the laboratory condition. They were allowed to sleep at 11pm and are awakened at 7.30am. After two nights of undisturbed sleep, on the third day speakers fitted near the bed emitted low level sound whenever the brain patterns of the samples indicate they are drifting to deep sleep. But the sound is not loud enough to wake them up it just attempted to reduce deep sleep to 90 per cent and bring them back to lighter sleep.
The attempt tried to imitate the sleeping pattern of people over the age of 60 who normally get only 20 minutes of deep sleep as against 80 to 100 minutes for young adults. After subjecting the sample to nine days of sleep interruption they were thoroughly tested. The insulin sensitivity of the samples had decreased by 25 percent that implied that they need more insulin to dispose the same amount of glucose. At the same time insulin secretion had not raised in eight members of the sample as a result their blood glucose level showed a 23 percent increase.
So enough sleep is needed to stay healthy both physically and mentally. Don’t avoid sleep at any cost that is the hint we get from the study conducted by the researches at the University of Chicago.

According to the US Census Bureau, by 2010 sub Saharan Africa will have suffered 71mn deaths due to AIDS. By comparison, the bubonic plague of the Middle Ages killed some 30mn people. These are staggering figures, particularly if one considers that deaths from AIDS are only part of the problems affecting African women and children.
Experts at the UN warn that most of the sub-Saharan countries will be unable to reach the Millennium goals related to health for 2015, particularly those related to improving the health of mothers and children. In fact, many diseases affecting children and adults can be addressed with minimum resources —if they are used strategically.
Childhood malnutrition is a critical issue. Almost 60% of deaths of children under five in developing countries are due to malnutrition and its effects –such as greater mortality from infectious diseases. It is estimated that African women are 10 to 100 times more likely to die during pregnancy and childbirth than women in the industrialised countries. Most of these deaths and disabilities are caused by delays in recognizing complications, difficulties in reaching a medical facility and lack of adequate medical care. Skilled health workers are vital in addressing these challenges but their numbers are pitifully low.
Malaria, HIV/AIDS, and tuberculosis continue to be major threats facing both children and adults. Recent studies have shown that HIV treatment is “failing” in many African countries. The rates of failure vary depending on the programme and the country under consideration. Treatment failure in many patients is due to their starting to take medication too late in the course of the infection. Other patients have problems in accessing the drugs, either because they are too poor or live too far away from the health center providing the medication. Throughout Africa, the stigma associated with HIV/AIDS is one of the main barriers in dealing successfully with that infection, both in terms of prevention and treatment. Education, public health campaigns and the active participation of members of the clergy have contributed in many areas to overcoming the stigma but much remains to be done and progress is slow.
Solving the problem of poverty and the resulting malnutrition and disease it engenders requires three distinct steps: first, the development of efficient and effective healthcare systems; second, increasing access of the poor to adequate healthcare; and third, redirecting resources from acute care hospitals using high-tech equipment to investment in low-tech, but effective, community-based primary and preventive care.
Health problems in Africa cannot be considered in isolation — and are not only the responsibility of Africans themselves. Foreign technical and financial assistance is required. Aid can strengthen civil society and community-based organisations which are the basis of a democratic society. To bring hope to a continent ravaged by poverty and disease, effective and urgent action is required. It is available and it can be done.
