Sleep loss in mice sends the brain’s immune cells into overdrive. This might be helpful in the short term, but could increase the risk of dementia in the long run

The brain starts to eat itself to clean up worn-out cells says the study.

The news comes on the heels of research that showed having too little sleep could put people at risk from heart disease.
The study found that having less than six hours sleep a night was associated with a higher risk of death in people with metabolic syndrome – a combination of diabetes, high blood pressure and obesity

Researchers said the effect was particularly strong in those with elevated blood pressure or poor glucose metabolism.

People with a common cluster of risk factors for heart disease and diabetes were around twice as likely to die of heart disease or stroke as people without the same set of risk factors if they failed to get more than six hours of sleep, according to the study published in the Journal of the American Heart Association.

For those who got more sleep, the risk of death was more modest.

Another study found that dehydration can cause headache.

Common as they are, headaches can be caused by a great number of things. What many people don’t realize is that dehydration is one of them. According to MedicalNewsToday.com, not having enough fluid in the body causes what is called a dehydration headache, which occurs when the brain pulls away from the skull as it shrinks temporarily due to the lack of fluid.

Recognizing a dehydration headache from other types of headaches is important, so you can treat it appropriately and avoid over-medication. It is important to keep in mind that a dehydration headache is different from a sinus headache or a tension headache in that the pain is contained in the area of your head, whether front, back, side, or all over. With dehydration headaches, you don’t feel facial pressure or pain the back of your neck. The pain can sometimes feel dull or intense, like a migraine.
