How does lack of sleep affect your Health?

No comments

If you eat well and exercise regularly but don’t get at least seven hours of sleep every night, you may undermine all your other effortsPeople who sleep less than seven hours a night have 40 to 60% lower levels of three molecules that are thought to play a key role in blood vessel health, according to a new study published in the journal Experimental Physiology
The molecules, called microRNAs, suppress gene expression of proteins in cells and have previously been linked to inflammation and poor blood vessel health.

How much sleep do you actually need?

Most adults need at least 7 hours of sleep each night.

What health conditions are linked to a lack of sleep?

Adults who sleep less than 7 hours each night are more likely to say they have had health problems, including heart attack, asthma, and depression. Some of these health problems raise the risk for heart disease, heart attack, and stroke. These health problems include:

Short-term problems can include:

Lack of alertness: Even missing as little as 1.5 hours can have an impact, research shows.

Impaired memory: Lack of sleep can affect your ability to think and to remember and process information.
Relationship stress: It can make you feel moody, and you can become more likely to have conflicts with others.
Quality of life: You may become less likely to participate in normal daily activities or to exercise.

Greater likelihood for car accidents: Drowsy driving accounts for thousands of crashes, injuries and fatalities each year, according to the National Highway Traffic Safety Administration.

If you continue to operate without enough sleep, you may see more long-term and serious health problems, some include:

Obesity. Lack of sleep can lead to unhealthy weight gain. This is especially true for children and adolescents, who need more sleep than adults. Not getting enough sleep may affect a part of the brain that controls hunger.

High blood pressure. During normal sleep, your blood pressure goes down. Having sleep problems means your blood pressure stays higher for a longer amount of time. High blood pressure is one of the leading risks for heart disease and stroke. 

Type 2 diabetes. Diabetes is a disease that causes sugar to build up in your blood, a condition that can damage your blood vessels. Some studies show that getting enough good sleep may help people improve blood sugar control.
