Bad Sleep Endangers Heart

Cardiologists usually focus on the major risk factors for heart disease — things such as high cholesterol, obesity, and high blood pressure.

But all too often, a very simple part of daily life is overlooked completely: sleep.

Sleep is actually a dynamic process involving changes in brainwave activity, breathing, heart rate, body temperature, and other physiological functions, enabling your body to perform many processes required for optimal health.

We now know that lack of sleep raises the risk for heart disease, as well as other ailments. Indeed, research now shows that sleep deprivation can be a

People need 8 to 10 hours of sleep each night. In the past, it was believed that older individuals didn’t require as much sleep as the young, but research is proving that theory to be a myth.

Ironically, it seems that the more sleep we need, the less of it we get. Nothing demonstrates this more than the inability of many people to get a good night’s sleep, especially as they grow older.

In fact, the older a person is, the more likely it becomes that he or she will have difficulty falling asleep and staying asleep. Older people also tend to wake up earlier.

On average, people who are 70 or older get one full hour less sleep each night than those who are in their 20s.

This is apparently due to changes that occur in the brain as we age. According to a new study published in the journal “Brain,” it has to do with a decline in the number of neurons, which are the nerve cells that carry messages from the brain to the rest of the body.

The fewer neurons there are in your brain, the more fragmented your sleep will be.

In addition, as people get older they are more likely to develop health problems that can rob them
of sleep. These include:

• Chronic obstructive pulmonary disease (COPD)

• Gastroesophageal reflux disease (GERD)

• Fibromyalgia

• Restless leg syndrome

• Diabetes

• Kidney failure

• Asthma

• Autoimmune diseases

Menopause, with its accompanying hot flashes and decreased hormone levels, can cause sleep disruption as well.

If you have any of these conditions and are having trouble sleeping, check with your doctor about treatments that can help
