Ever wake up with a numbing sensation in your legs, cramps, or swollen feet? If yes, this could be because of poor circulation of blood during your sleep. As per the American Heart Association (AHA), about 10-12 million adults aged over 40 in the U.S. battle complications due to improper blood flow, which often worsens at night. So, how to improve blood circulation in legs while sleeping? The answer is selecting a medium-firm mattress, sleeping in a proper position, and incorporating exercises in daily routine.
In this article, we will discuss the common causes and symptoms of poor blood circulation in the legs. You will learn about exercise and diet tips for the better flow of blood and get recommendations for the best mattress to tackle this health issue.
What Is Poor Leg Circulation and Why Does It Happen?
Poor leg circulation refers to reduced or impaired blood flow to the lower limbs. In medical terms, it is known as peripheral artery disease (PAD), which restricts the proper flow of blood and oxygen to your legs. It often becomes more noticeable at night, especially during sleep, when your body is inactive. This restricted circulation can cause uncomfortable symptoms like numbness, tingling, swelling, cold feet, or muscle cramps, which not only disrupt rest but can also point to deeper health concerns.
You can use a supportive mattress to relieve pressure on your blood vessels. This will encourage healthier circulation during sleep, especially when paired with proper sleep positions and elevation.
Causes of Poor Circulation in Legs
Poor blood circulation in the legs may result from multiple factors, like:
- Sedentary Lifestyle: One of the most common reasons is when you sit or stand for an extended period of time. This slows down the natural circulation of blood from leg muscles to the heart.
- Obesity: Excess bodyweight means excess pressure on your veins and arteries, which makes the pumping of blood difficult.
- Smoking: This habit can impact your overall arterial health, as tobacco may damage your blood vessel walls, promoting the buildup of plaque.
- Diabetes: High blood sugar can damage small blood vessels, which may lead to poor oxygen delivery.
- Peripheral artery disease (PAD): Atherosclerosis (plaque buildup) narrows leg arteries, causing cramping and pain known as claudication.
- Varicose veins: This condition occurs when vein valves weaken, causing blood to pool, veins to stretch, and circulation to slow down.
- Deep vein thrombosis (DVT): This can be life-threatening as it involves clotting of blood deep inside the vein. This condition blocks your normal blood circulation and should be treated immediately.
Symptoms of Poor Leg Circulation
To avoid further complications, it is important to identify common symptoms of impaired blood circulation. Watch out for:
- Numbness or tingling in your feet or calves
- Leg swelling or puffiness around the ankles
- Persistent cold feet that stay chilly even under blankets
- Muscle cramps or aching at night or upon waking up
- Leg pain at night that eases when you move or massage the area
The table below summarizes the causes of poor leg circulation, their impact, and common symptoms:
| Cause | Impact on Circulation | Common Symptoms |
| Sedentary Lifestyle | Lack of muscle movement slows blood flow | Swelling Numbness |
| Obesity | Increases pressure on the veins | Leg pain Swelling |
| Smoking | Damages blood vessel walls | Cold feet Tingling |
| Diabetes | Damages blood vessels over time | Numbness Slow-healing wounds |
| Peripheral Artery Disease | Narrowing of the arteries, reducing blood flow | Leg pain Cramping |
| Varicose Veins | Disrupts normal blood flow | Visible veins Aching legs |
| Deep Vein Thrombosis | It can block veins and can be life-threatening | Swelling Leg pain Warmth in the affected area |

How Your Sleep Position and Environment Impact Blood Flow?
Before finding the solution to ease your leg pain, you must understand the deep relationship between your sleep and circulation. Even small changes in sleeping position and bed adjustments can make a major difference in opening up your blood vessels.
If you are wondering how to improve circulation in legs naturally, you can follow these sleeping position tips:
Lie On Your Back With Legs Elevated
You can use gravity to your advantage by lifting your legs slightly for better blood flow towards your calves and feet. A Journal of Vascular Surgery study found that lifting legs about 30 cm above heart level increased small-vessel blood flow by 45% in people with chronic venous insufficiency. This cuts down on blood pooling and helps with increased flow through the veins.
Sleeping On The Side With A Pillow Between Your Knees
You can place a pillow or rolled towel between your knees. It will align the hips and reduce pressure on your lower body. This posture supports smoother circulation through the pelvic region and legs. Avoid curling into a tight fetal position or letting your top leg fall forward, as these can compress veins and restrict blood flow. For example, curling into a fetal position or letting your upper leg go forward while sleeping on your side may pinch the veins and impair the flow.
Sleep Quality & Circulation: What the Research Shows
In fact, research using the Pittsburgh Sleep Quality Index found that people who report bad sleep quality often suffer from insufficiency in vein functions. This points to a vicious cycle, where slight discomfort impacts your sleep quality, which further leads to circulatory issues in the body.
Other than sleeping posture, your cardiovascular system’s function also depends on the total time and patterns of sleep, as:
- When you get an insufficient amount of sleep, this may worsen your blood pressure and inflammation. This further results in long-term stiffness in the arteries.
- If you do not have a fixed sleep schedule, with erratic sleeping hours, you may negatively impact your body’s internal clock or circadian rhythm. You become prone to cardiovascular and metabolic risks.
Create a Circulation-Friendly Sleep Environment
Try to have a consistent sleeping pattern each night and aim for at least 7 to 8 hours of uninterrupted sleep. This routine will support your arterial and venous functions by relieving them from any stress or strain. Additionally, you must invest in the following circulation-friendly items to improve your sleep environment:
- Adjustable beds with maintain circulation-specific presets for proper bed positioning. If you’re considering this option, explore key adjustable bed benefits versus traditional beds. These presets include various inclination settings for your legs, helping you avoid pillows or wedges that may slip during the night.
- Invest in a good quality medium-firm mattress with contouring features and pressure relief. These mattresses support your hips and thighs for unobstructed blood circulation.
How to Choose the Right Mattress and Bedding for Optimal Leg Circulation?
For healthy legs and a happy circulatory system, you need more than simple lifestyle changes. Products like a medium-firm mattress (5-7 out of 10 on the firmness scale) can be a total game-changer when it comes to supporting your muscles and giving you pressure relief. To build an efficient sleep environment, you also need cooling bedding and an adjustable bed for health-specific inclination presets. These aid in maintaining your optimal vascular health while you focus on getting that restorative sleep.
Look for these features before choosing the right mattress and bedding products for good leg circulation:
Mattress Firmness and Pressure Relief
A medium-firm mattress cushions your hips and thighs just enough to prevent pressure points that can compress blood vessels and impede blood flow. This highlights the importance of choosing the right mattress for vascular health. According to the Sleep Foundation, materials like gel-infused memory foam and natural latex offer adaptive support and cooling. These help you maintain open capillaries and prevent vasoconstriction (contraction in blood vessels) caused by overheating.
The table below compares various types of mattresses and their impact on blood circulation:
| Mattress Type | Support for Alignment | Temperature Regulation | Adjustability | Best For |
| Memory Foam | Excellent | Good (with gel infusion) | Low | Side sleepers, pressure relief |
| Latex | Very Good | Excellent | Low | All sleepers, eco-friendly |
| Hybrid | Excellent | Good | Medium (with adjustable base) | Combination sleepers, support |
| Innerspring | Good | Poor | High (with adjustable base) | Back sleepers, budget-friendly |

Adjustable Beds for Circulation
To ensure you sleep with proper leg elevation, get an adjustable bed frame with settings that will give you exactly 30 cm lift above heart level. For this, these beds use a bed base with tilt presets or a built-in leg rest for a zero gravity position. The RESNA position paper shows that this lift reduces venous pressure and boosts capillary flow. It also comforts people with peripheral vascular disease and improves their overall vein health.
Temperature-regulating Bedding
Cool bedding is important to prevent vessel constriction, often triggered by overheating while sleeping. Use bedsheets that are breathable with moisture-wicking fabrics like Tencel or bamboo. You can also get a mattress with cooling tech (gel-infused layers or ventilated latex), to avoid night sweats and experience complete relaxation.
Pillows and Positioning
If an adjustable bed seems out of your budget, worry not. You can just use your regular pillow under your knees to maintain a good sleeping posture. For better results, use a contour or wedge pillow to lift your calves or knees to give you the recommended inclination level. This setup and positioning will keep your knees and hips aligned to prevent pinching of veins while sleeping.
Simple Steps to Boost Leg Circulation During Sleep
You do not need extensive medical interventions to improve the function of your circulatory system. By following these simple and natural remedies for poor circulation, you ensure a restful sleep and target happy feet:
- Elevating legs for better circulation: Use bed wedges, an adjustable bed, or firm pillows to lift your calves about 30 cm (12 inches) above heart level.
- Compression stockings for sleeping: Many medical experts recommend these stockings (15-20 mmHg) as they provide moderate pressure from your ankles to your calves. This improves the blood-pumping functions and reduces the pooling of fluids overnight. Always consult your doctor before using these.
- Avoid restrictive positions: Try following recommended sleeping positions to improve circulation. These include using a pillow between your knees or extending your legs to prevent veins from pinching.
- Stay hydrated: Hydration and blood flow work together to ensure good heart and blood vessel health. So, make sure you drink 2-3 litres of water per day.
- Choose breathable bedding: Buy moisture-wicking sheets (bamboo or Tencel fabric) and a medium-firm mattress with cooling layers (gel-infused foam or latex). These will regulate your body temperature and relax your blood vessels.
These easy steps, from sleeping posture to compression stockings for circulation, help you maintain a healthy lifestyle for your legs. To enhance their effectiveness, you can support them with an adjustable bed and a medium-firm mattress to wake up light and energized each day.
Let us look at the summary of these steps in the table below:

Beyond Sleep: Daily Habits to Enhance Leg Circulation
To keep your circulatory system healthy in the long term, you need more than these small lifestyle tweaks. You must make changes to your daily eating habits and routines that aid in keeping your body in its best form. Here are some of the best exercises for leg circulation, diet, and other changes that will ensure your optimal health:
Move Regularly
Include any kind of moderate-intensity exercise for circulation, like brisk walking, swimming, or cycling, in your daily routine. Give it at least 30 minutes of your time each day to see better results. Research by the Centers for Disease Control and Prevention (CDC) shows that physical activity can lower the occurrence of PAD by up to 40%.
Eat For Vascular Health
Follow a diet for circulation rich in omega-3 fatty acids (fish or flaxseed) and antioxidants (blueberries or leafy greens). Include lean proteins in your daily diet to nourish your vascular system. A 2023 AHA advisory shows that omega-3 fatty acids help reduce inflammation and maintain healthy blood pressure.
Quit Smoking
Tobacco is a harmful substance that is proven to damage the blood vessels and eventually slow down blood flow. If you are a smoker, try gradually abstaining from smoking, and within just weeks, you will start feeling better.
Manage Stress
Stress can be a major factor that can impact your overall sleep quality. Along with physical activity, include meditation, yoga, and deep-breathing exercises daily. This will make your nervous system calmer and reduce stress on your vascular functions for better oxygen delivery.
Maintain a Healthy Weight
Target a healthy body fat-to-muscle ratio to boost your overall vitality. This will reduce the pressure on your legs, making circulation easier and your heart healthy.
The summary table for blood-circulation-related exercises is given below:
| Exercise | Impact on Circulation | Time Required | Best For |
| Walking | High | 30 min/day | General circulation and low impact |
| Cycling | High | 20-30 min/day | Leg muscle strength |
| Swimming | Moderate | 30 min/day | Joint-friendly and full-body workout |

Managing Poor Circulation with Specific Health Conditions
You need optimum sleep and daily healthy habits to maintain healthy circulation of blood in your body. However, if you have certain health issues, these natural steps may not suffice. You may need medical consultation and supportive products like mattresses or bed frames to ease your discomfort. Let us have a detailed look at these solutions:
Varicose Veins and Circulation
Weak vein valves result in pooling of blood, which further stretches the walls of blood vessels. In the long term, this leads to a condition known as varicose veins, with dark and visible bulging veins in the legs. The symptoms include aching, cramping, and itching of the legs, which can affect your sleep at night and daily functions. You can manage these symptoms by:
- Use a medium-firm mattress with an adjustable bed frame that raises your knees and calves to prevent blood from pooling at night.
- Place a firm pillow under your knees or lift your calves with a wedge pillow under your mattress bedding for a secure inclination.
PAD and Sleep
When experiencing impaired blood circulation over a long period, you may develop a condition called peripheral artery disease (PAD). This causes your leg arteries to narrow, leading to cramps, fatigue when walking, and cold feet at night. Studies even show that 35% of PAD patients face a higher risk of restless leg syndrome (RLS). This can further disrupt your sleep pattern and lower your overall sleep quality. Additionally, one study found a 74% increase in the occurrence of PAD among people sleeping less than 5 hours per night. To avoid this, you must:
- Choose a supportive mattress that aids your pressure points around the hips and thighs for better flow through the arteries.
- Use adjustable beds for circulation to raise your torso and legs. This will improve overall blood flow.
Diabetes and Leg Circulation
Diabetic patients often face numbness, cold feet, and sores at night. This is because high blood sugar levels lead to fatty deposits in the veins and damage the blood vessel walls. To ease these symptoms while sleeping:
- Use a mattress with temperature-regulating technology, using materials like gel-infused memory foam or latex to avoid narrowing of vessels due to heat.
- To improve oxygen delivery to your feet and reduce pressure on heels, take a thin wedge pillow and place it under your ankles at night.
When to Seek Medical Advice
Despite these preventive measures, if you see severe and persistent leg swelling, pain at night, open sores, or changes in skin color, consult a professional immediately. This early intervention can prevent you from developing serious and life-threatening conditions like deep vein thrombosis by providing you with proper treatment.
Frequently Asked Questions
What is the best sleeping position for leg circulation?
For better leg circulation, try following the semi-Fowler position. This includes lifting your torso at an angle of 15-45° with pillows or an adjustable bed. This enhances the pumping action of the blood from your legs to the heart with the gravity effect. Try to keep your legs straight while sleeping or keep them slightly bent to avoid pinching. Another effective position is sleeping on your side with a pillow between your knees for better alignment.
Can a mattress improve leg circulation?
A mattress can certainly improve the blood flow towards your legs by easing the stress from your ankles and calves. This is because they use materials like memory foam and latex that conform to your body’s curves, opening up your blood vessels.
Many hybrid mattresses in the market use coils and foam layers to manage the bounce and improve airflow to regulate temperature at night. For best results, use a quality mattress with an adjustable bed base to improve your circulatory functions.
How do I know if I have poor leg circulation?
The common symptoms of impaired leg circulation include pins-and-needles sensation, numbness, cramps in the calves, or cold feet at night. Such persistent symptoms may also lead to swollen ankles, varicose veins, or open sores. Even your skin color may show sudden changes, becoming pale, bluish, or discolored.
Other small but significant signs show up as hair loss on the legs and slower toenail growth. If you experience extreme pain while walking that reduces when at rest, this may also be a sign of poor circulatory health.
Are there exercises to improve leg circulation while sleeping?
To improve your leg circulation at home, you can follow many exercises daily before bedtime. Before sleeping, lie on your bed and do ankle pumps, leg lifts, and moderate knee bends to activate your muscles for better blood pumping towards your heart. Point toes up and down ten times, bend each knee to your chest, then lift one straight leg while keeping the other bent.
Perform consistent repetitions of these easy exercises before and during sleep. Lightly stretch in the morning and massage your feet at night to improve overall arterial health.
What foods help improve circulation?
The best diet for improving circulation includes the following food combinations for optimum nutrition:
– Foods rich in nitrates, antioxidants, and omega-3 fatty acids boost circulation.
– Beets and leafy greens convert nitrates to nitric oxide, good for blood vessels.
– Berries, pomegranate juice, and dark chocolate provide polyphenols that support vessel health.
– Fatty fish deliver anti-inflammatory omega-3s, while garlic and turmeric improve blood flow.
– A combination of walnuts, almonds, citrus fruits, ginger, and cayenne pepper nourishes your circulatory system.
Can compression stockings be worn while sleeping?
You can wear compression stockings at night to support your veins, but these are not necessary for everyone. Sleeping on a flat surface naturally improves your blood flow, and adding compression to this may give you skin rashes or sores. However, if you are going through post-surgical recovery or severe lymphedema, you can get medical advice for its use. If your doctor agrees, buy low-compression socks of about 15-20 mmHg for a good night’s sleep. Make sure they fit you properly and use them with precaution to avoid over-compression.
Is it normal to have cold feet at night?
Many get cold feet at night due to a decrease in temperature or low body fat. However, if it is persistent and is impacting your sleep, this may be due to stress, anxiety, or impaired circulation in your feet. If it is accompanied by cramps, tingling, or sores, you may be at risk of developing serious circulatory issues like PAD, RLS, or Raynaud’s. To manage these symptoms, you must use heating pads and exercise daily. Consult a doctor if your symptoms worsen.
Conclusion
In your quest to find the solution for how to improve blood circulation in legs while sleeping, first understand how sleep is deeply connected with your blood circulation. Sleeping for at least 7-8 hours daily ensures you get a proper flow of oxygen and nutrition through blood circulation in each of your body parts. For this, ensure you include recommended sleeping positions with the right setup that includes a medium-firm mattress and an adjustable bed frame. You can also use your regular bed with wedge pillows and cushions to optimize your sleep for optimal blood circulation. Other than these simple steps, keep your body hydrated, move regularly, stretch before and after sleeping, and wear compression socks for a restful sleep.
