4. Increased LDL and Decreased HDL Cholesterol
Low-density lipoprotein (LDL) is the body’s harmful cholesterol. It is directly responsible for clogging arteries and causing heart attacks.
LDL builds up in your arteries over time and blocks them, thereby obstructing the flow of oxygen-rich blood to the heart. This arterial blockage is referred to as coronary artery disease (CAD) and is responsible for triggering a heart attack.
Shorter sleep duration was positively associated with greater levels of LDL cholesterol, and optimal sleep was associated with decreased LDL levels, according to a 2010 article published in Sleep.
On the other hand, high-density lipoprotein (HDL) is the good cholesterol in your body. It is responsible for identifying and channeling excess LDL to the liver for breaking down so it does not harm you.
The higher the LDL in your body, the lower the HDL will be. Sleep deprivation is also associated with a lower level of HDL in the body, which is another factor indicative of an increased risk of heart disease.
5. High Triglyceride Level
Triglycerides are fats found in your blood, and an elevated triglyceride level is one of the factors that increase the risk of heart disease and heart attacks.
The duration of sleep at night affects triglyceride production in the body.
People who slept less than 5 hours reported elevated triglyceride levels, according to a 2008 study published in Sleep.
6. Increased Belly Fat
The fat that collects around your waist is the hardest to get rid of.
It is also the most dangerous as it substantially increases your risk of developing heart disease and possible heart attacks.
People who suffered sleep deprivation along with obstructive sleep apnea reported increased body weight and abdominal/waist fat, according to a 2005 study published in Sleep.
