Your brain is more active during REM sleep (since you're dreaming), so it requires more oxygen—as a result, blood flow all over the body increases.
Our circulatory system works best when we're upright and moving. When we spend many hours lying down, blood pools in the legs, lower volumes of blood are pumped through the body even though the heart works harder, oxygen uptake is reduced, and the risk of blood clots is increased, particularly in the legs and lungs.
Blood flow and neural activity greatly increase during both non-rapid eye movement sleep and rapid eye movement sleep stages, according to Penn State researchers.
When you're standing, gravity helps push blood into your feet. But when you lie down, you lose the help of gravity, so circulation to the area decreases even further.

Pulsatile tinnitus is often caused by disorders or malformations in the blood vessels and arteries, especially those near the ears. These abnormalities or disorders — including aneurysms and arteriovenous malformations — can cause a change in the blood flow through the affected blood vessels.
Chronic venous insufficiency occurs when your leg veins don't allow blood to flow back up to your heart. Normally, the valves in your veins make sure that blood flows toward your heart. But when these valves don't work well, blood can also flow backwards. This can cause blood to collect (pool) in your legs.
Sleeping on your left side to make it easier for blood to flow in and around your heart. Keeping your arms at your sides instead of under or behind your head. Making sure your pillow supports your neck and spine and keeps them neutrally aligned.
Similarly, sleeping on your left side, specifically, could help the flow of blood to your heart. When your heart pumps blood out to your body, it gets circulated and then flows back to your heart on the right side, Winter explains.
This increases blood flow to the reticular formation, a part of the brain stem responsible for the sleep-wake cycle. (Basically, it's a shot of espresso to the brain.) While not scientifically proven, sending a rush of fresh blood to the area may flip the “wake” switch and give you a natural, much-needed boost.
A rise in blood pressure overnight to early morning has been linked to an increased risk of heart disease. An irregular blood pressure pattern could also mean that you have: Poorly controlled high blood pressure. Obstructive sleep apnea.
The primary signs and symptoms of blood pooling include: Swelling. Varicose veins. Cramps.
While making a habit of spending the day in bed or on the couch is not good for anyone, using it as a well-placed conscious tool for your emotional and mental well-being is absolutely ok. As a matter of fact, it's an investment in your health.
Prolonged Immobility
Sitting or lying down for long periods—due to prolonged bed rest after illness or a long airplane flight, for example—can cause blood to pool in the legs, leading to deep vein thrombosis (DVT) and, worst-case scenario, pulmonary embolism if the clot travels to the lungs.
When you sleep on the floor, your body weight is distributed evenly. This can help improve your blood circulation, allowing your heart, lungs, and muscles to function effectively.
Pull your knees up slightly toward your chest. The pillow for your head should keep your spine straight. A rolled towel or small pillow under your waist may also help support your spine. Insert pillows into gaps between your body and the mattress.
Wearing compression garments can help blood that is pooling in the leg, ankle, or foot to flow in the right direction—toward the heart. Your doctor may prescribe elastic compression stockings or socks made with a flexible, gradated fabric.
To reduce swelling and improve blood flow, it's important to keep your legs elevated. Wearing compression stockings may also help. Regular exercise can also be an excellent way to boost the health of one's leg veins by improving their cardiovascular system with increased circulation!
When you elevate your legs, you allow gravity to naturally bring blood back toward your heart. This will likely make your legs feel less achy and swollen, and feels especially good at the end of a long day.
Symptoms of poor circulation are often easy to spot. They include muscle cramping, constant foot pain, and pain and throbbing in the arms and legs. As well as fatigue, varicose veins, and digestive issues. Leg cramps while walking and wounds that don't seem to heal in your legs, feet, and toes are also symptoms.
Some people get heart palpitations when lying down because of the position in which they sleep. Sleeping hunched over on your side can increase pressure inside your body, causing palpitations. Many other common causes of heart palpitations include: Anxiety, stress and depression.
