Guide to Bad Sitting Posture

Bad sitting posture can be the first step to bad health and constant body pain.

Chronic pains are among many ailments when you neglect your posture. This guide will help you identify when your posture is bad and needs corrections.

After all, practice makes perfect, and this guide has all tips and tools to fix your posture.

Identifying Bad Sitting Posture

Identifying bad sitting position

The clearest sign of good or correct posture on a child would have an 'S' curve on their back and can move with grace.

Good spinal posture should feel very natural, encouraging you to only make minor adjustments. You should focus on how your body feels from any underlying tension.

Maintaining good posture when focusing on work or other tasks can distract us from maintaining good posture.

This can lead us to create bad posture habits to stay comfortable during inactivity.

Physical Signs of Poor Posture

Unconscious slouching and inactivity are the main culprits for poor posture and complications.

This lack of movement leads to chronic back pain, spinal and joint dysfunction, etc. It also exacerbates weight gain with a pot belly and rounded shoulders.

These signs will lead to more strain on your body and stifle the hemodynamics in your body.

Your nutrient-carrying blood will have difficulty reaching your brain, making daily life harder.

Other symptoms include the following:

  • Bent knees as you stand or walk
  • Necks excessive leaning forward or backward
  • Body aches
  • Headache
  • Excessive muscle tension

The Role of Ergonomics

Regular exercise and ergonomics have the role of habit formation throughout your day.

Exercise can hone your body, but the environment also shapes daily behaviour. Many habits are formed as we focus on a task, and the temptation to slouch is constant.

So people consider the position of their equipment for more leg space and less muscle strain. All are done to maintain a healthy spine and a more comfortable lifestyle.

Ergonomic home office setup

Ergonomics should be able to let you be flexible despite the limited spaces.

All the while conditioning your body to do the following:

  • Back straight
  • Head up, chin in, and looking straight ahead
  • Shoulders relaxed
  • Tummy in
  • Weight balanced evenly on your two feet
  • Knees straight

To support these healthy postures, the quality and design of the furniture we use become crucial. Ergonomic chairs, in particular, play a significant role in maintaining proper alignment and reducing strain.

Standards For Ergonomic Office Chairs

Standard measurements for appropriately designed ergonomic office chairs fall within the 17–20 inch width range. Nonetheless, the chair's depth also plays a significant role in achieving ideal comfort and support.

A suitable seat depth allows users to place their backs against the chair's backrest while keeping a small gap of approximately 2 to 4 inches between the back of their knees and the chair seat.

Features of an Ergonomic Seat

Realizing this essential balance offers exemplary lumbar support and overall office chair ergonomics

There are a few quintessential characteristics to look for when it comes to ergonomic office chairs.

  1. Adjustable Seat Height: Optimal ergonomic design includes a seat height that can be adjusted according to the user's specific needs and stature.
  2. Seat Tilt: A tilt mechanism facilitates forward and backward tilt, enabling better distribution of the user’s weight and minimising strain.
  3. Tailored Backrest Tilt: The ability to adjust the backrest tilt results in better posture alignment and lean-back comfort.
  4. Right depth: Ergonomic chairs should have enough space from the front to the back of the seat so that you can rest your back against the backrest, with about 2 to 4 inches between the back of the knees and the seat of the chair.

Difference Between Ergonomic Chair And Normal Chair

Ergonomic chairs and normal chairs are distinguishable mainly by their user-oriented design. Ergonomic chairs typically prioritize comfort and body support, while normal chairs often do not.

By learning how to choose an ergonomic chair, you will learn that each element of an ergonomic chair is adjustable to fit individual body specifications, thereby reducing the chances of developing stiffness, cervical complications, or other physical discomforts associated with static seating.

What Classifies A Chair As Ergonomic?

Ergonomic chairs garner their name from the distinct design principles they follow. Predominantly, they support the spine's natural curvature, which is essentially a gentle 'S' shape. The adjustable backrest of an ergonomic chair allows users to match the chair's curvature with their spine for optimal support.

This alignment reduces undue stress on the spine and pelvis, thereby classifying a chair as truly ergonomic. For a broad range of such ergonomic office chairs, you can check out our collection at Desky.

Health Effects of Bad Sitting Posture

Chronic pain is one of the most well-known negative consequences of prolonged sitting, but there are more risks.

From difficulty breathing to even mental health, posture impacts many factors important to our daily life.

Pain and Discomfort

Long periods of inactivity causes your muscles to tense up and create back pain within your spine.

This pain can range from stiffness in the shoulder area or numbness in one leg.

Yet, there are worse cases, such as Scheuermann's disease or juvenile discogenic diseases.

This disease is characterised by abnormal thoracic spine growth but can be fixed with physical therapy.

The disease may be rare, but people can take their posture for granted as they don't feel the pain yet.

Back pain gets worse as people get older as we lose muscle strength.

IMPORTANT NOTE: The core muscles are your abdomen, pelvic floor muscles, and upper back.

Musculoskeletal Issues

Your skeletal muscle fibre system has two varieties: static or slow twitch and phasic or fast-twitch muscle fibres.

Static muscle fibres maintain posture by detecting imbalances in our bodies.

All within our deeper muscle layers.

As they send messages to the brain, these muscle fibres burn energy slowly and endure for long hours.

On the other hand, phasic muscle fibres monitor the movement and activity of the brain but tire easily.

Bad posture can cause muscle strain as they rely on phasic fibres instead of static ones to maintain a correct position.

Over time, poor posture would need more attention from phasic fibres, leading to your muscles atrophying.

Digestive Problems

Poor posture (ex. bending your knees lower than your hip) can promote constipation.

This position impedes your abdominal muscles' ability to move your waste out, straining bowel movement and negatively affecting the digestion process.

Decreased metabolism is from slowed hemodynamics in distributing nutrients or waste.

All are leading to fewer than three bowel movements a week.

Slouching after meals can also cause cases of heartburn due to acid reflux.

Respiratory Issues

Stress incontinence from poor posture has you leak urine while laughing or coughing.

The pressure from your pelvic and abdominal muscles weakens your bladder's resistance.

Respiratory issues lessen your lung capacity by limiting the thoracic cavity.

Our diaphragms limit lung capacity whenever we slouch, as there is insufficient space to move.

Mental Health and Self-Esteem

Slouching can be a "position of defeat" as negative emotions and memories are easier to recall when slouching.

While the opposite is true, more positive memories are easier to recall when standing up straight.

Thus, a better posture can help lessen negativity and anxiety during prolonged hours.

From my experience, people go through long hours of slouching without realising it. These extended periods can result in accumulated emotional stress.

Slowed blood flow can have lingering hormones promoting these anxieties in your head.

Correcting Bad Sitting Posture

Correcting bad sitting posture

Bad posture is an issue that can affect anyone regardless of age and is endemic in our current era.

The research shows that people go through long inactivity at work or while resting.

Professionals and proper ergonomic sitting techniques should help improve your posture.

These professionals range from your doctor to your physiotherapist and chiropractors. They give insights on how to properly construct your environment and techniques.

Here are general techniques they would give each patient to prevent back pain.

Positioning Techniques

Should our sense of balance be taken over by phasic fibres, our body would further contract against gravity.

Naturally, this continuous contraction would lead to more body pain and fatigue due to poor posture.

"Curve Reversal" is the general rule of stretching in the reverse direction you lean into as you sit.

You can prevent neck pain by stretching your neck muscles as you turn your neck from side to side.

Even something as simple as using a pillow to support your neck can prevent further pain.

Some techniques can help your bowels and lower your spine by lessening pressure on one side.

For example, try keeping your back and spine straight while you lean forward at your hips but higher than your knees.

Active Sitting

Active sitting is the practice of keeping yourself aware of your position as you sit or stand.

Staying in one position for long periods of time can build up tension within your spine. The best position remains to keep your head aligned with your spine when you sit.

Any excessive leaning on your head can add stress to the cervical spine.

An ergonomic chair is designed to provide support to your back and spine, enabling you to maintain proper posture even during extended periods of sitting.

Strengthening and Stretching Exercises

Doing stretching and strengthening exercises every few days maintains your muscles.

You will need constant maintenance to remain strong, flexible, and comfortable daily.

Weakened support or core muscles will tighten and shorten your muscles.

This may compact the bones of your spine, thorax, vertebral column, and other vertebrae, further worsening your posture.

Strengthened neck and back muscles can also ease any symptoms of tech neck.

It's also best to lift with your thighs, hips, and knees or risk lower back pain.

The fruits of your regular exercises should result in the following for your support muscles;

  • Rounded shoulders
  • Flattened back
  • Protruding shoulders
  • Firmer hamstrings in your thighs

Workplace and Home Adjustments

You should avoid sitting or standing in one position for long periods of time or risk your muscles tightening.

You can also cross your legs at the ankle instead of the knee as you keep your feet flat on the ground.

It's best to sit back in your seat anywhere with your lower body at a right angle.

Legs apart while keeping your knees and hips at the same height when working for long periods.

Even behind the steering wheel, you can keep good posture by being level to your chest at arm's length.

Maintaining Good Posture

Maintaining good posture in the office

You can achieve good posture with these practices as you correct your bad habits.

You can improve posture with a clear head and consistent reminders about your sense of balance.

These tips to achieve good posture are simple guidelines to add to your daily routine from my experience.

Periodic Posture Evaluations

The best position is a neutral spine, wherein the spine is upright and balanced with your height.

You can maintain a neutral spine by keeping your shoulders down and your head back, engaging your core muscles.

You can bolster your core muscle strength and length by moving your belly button.

From my research, you can use lumbar support or a pillow while in a sitting position anywhere.

The simplest reminder to have is to keep your spine straight often.

Building Posture Awareness

You can build better posture awareness with a more ergonomic chair instead of a softer chair.

Keeping yourself in a different position each hour loosens tension in the upper body. Abdominals are especially important as they support your lower back and spine.

You can further support these muscles with abdominal crunches instead of straight-backed sit-ups.

Establishing Healthy Habits

A more ergonomic chair and space can help prevent your remaining on one side. A lower spine support pillow can remind you to remain upright in a chair or to change positions often. You can also use a supportive mattress to prevent neck pain and keep your spine perpendicular.

Another instance would be whenever you are lifting heavy weights. Make sure to use your thigh muscles while keeping your back straight.

Most Ergonomic Position for Reading

When seated at a desk, your feet should be flat on the floor. But of course, curling up on a couch or lounging with feet propped on an ottoman also makes for enjoyable reading. It's important to maintain a somewhat upright position.

As a tip, use a 90-degree-angle posture between your torso and your legs. Consider having a pillow in your lap to elevate your book slightly for better alignment.

Best Position For Reading

Try holding your reading material a little below eye level. The aim here is to avoid forward slouching. Bent elbows aid in holding the book up, while lowering the book toward your lap may cause neck bending, resulting in strained neck and upper back muscles.

Your body working too hard can result in a multitude of issues, so eye comfort and overall enjoyment of your book will improve with this technique.

Best Reading Angle

healthy reading distance — approximately 15 inches, combined with a 60-degree reading angle generally provides an optimal balance between comfort and eye strain.

Bifocal wearers might find a slightly lower angle more suitable. It’s worth noting that your eyes need to focus upward if you like reading lying down. Consistently reading at this angle might cause eyestrain over prolonged periods.

In addition to these healthy habits, creating an ergonomic workspace is essential to maintaining good posture and reducing strain. By optimizing your environment, you can further enhance your comfort and productivity throughout the day.

Successfully Setting Up Your Space For Ergonomics

Optimal Space for a Desk Chair

Suppose you are using a regular chair. In that case, you will require roughly 23 to 25 inches of clearance from the edge of the desk to the closest wall or furniture piece. Ergonomic office chairs, on the other hand, demand more space due to their larger size and greater functionality. Therefore, a gap of 30 to 32 inches behind your desk proves adequate for accommodating an ergonomic chair.

Minimum Chair Space Requirement

The minimum office chair space depends on several factors, such as the size of the chair, the desk, the room, and the user’s comfort. However, a general rule of thumb is to have at least 42 inches square of space around the chair for easy movement, and at least 20 to 30 inches of space behind the desk.

If the chair is near a wall, there should be at least 36 inches of space between them. You can also use a chair mat or a rug to protect the floor and provide a smooth rolling experience. Having enough space around your office chair can improve your posture, productivity, and safety.

Width Requirement for a Desk Opening for a Chair

Consider the space for placing the chair underneath your desk. As a general rule, allow at least 23 inches of clearance for a standard-sized chair. However, if your plans include a generous-sized office chair, you’ll require a chair allowance of at least 30 inches.

Sure, enough room for your chairs contributes to a cozy workspace. But it also makes your tasks effortless – whether it's reaching for the printer, the filing cabinet, or making a swift exit.

Clearance Necessity Between a Chair and a Desk

For an ideal setup that strikes a balance between functionality and comfort, you should abide by certain measurements. We suggest keeping anywhere from 48 to 60 inches clearance for seating that faces your desk.

Include 20-30 inches of space between the desk and the chairs. The layout allowed should accommodate the furniture, permits guests to comfortably reach the seats, and gives room for their legs and feet when sitting.

Context of Large Ergonomic Chairs

Ergonomic chairs have wider, pillowy seats and extended backrests to keep up with your body shape. These features, while enhancing your comfort and productivity, necessarily warrant more room within your office space. In a similar vein, ergonomics is not only about improvising physical comfort but also about your movement. Hence, ample space is needed around the chair and the desk to facilitate smooth transitions and prevent congestion.

Mesh Chairs

Mesh office chairs are known for their cooling ability; this versatility is owed to the unique features of their construction material. Unlike traditional chairs often clad in thick upholstery, mesh chairs encourage air flow. Subsequently, this ensures that no matter how blazing hot summer gets, your work comfort remains uncompromised. A scientific study published in NCBI affirms that optimal air circulation significantly improves comfort in office environments.

Mesh Back Chairs Longevity

The durability of mesh chairs often influences their purchase. While a high-quality mesh chair provides efficient service, inexpensive options may become deformed over time due to weight pressure, leading to sagging and decline in durability.

However, according to OSHA, choosing a chair that is well-designed and correctly adjusted is essential for maintaining good posture and preventing workplace injuries, regardless of material.

Mesh vs. Foam Chairs

Is mesh a superior option to foam? From a breathability perspective, mesh chairs certainly surpass upholstered foam chairs. The structure of the mesh allows air to traverse freely through the backrest and the seat. For those who sit at their desks for long hours, this ability to stay cool and comfortable is a significant advantage.

Comparing Mesh and Foam

  • Mesh chairs promote airflow, contributing to a cooling effect during extended sitting sessions.
  • Foam chairs, though cushy and supportive, may lock in heat and become uncomfortable over time.

Disadvantages Of Mesh Office Chairs

Nevertheless, mesh chairs have their limitations. Most notably, repairing or replacing the damaged mesh can be more challenging than dealing with fabric chairs. Meshes of lower quality often show extremes of hardness or softness and stretch quickly with usage. Inferior-quality chairs lack sufficient flexibility, causing significant pressure on the tailbone due to body weight.

Frequently Asked Questions

We already discussed the causes and cures against bad posture and the habits supporting them.

However, this section provides additional knowledge to help you maintain proper posture.

How Does Bad Sitting Posture Affect Mental Health?

An improper sitting position can make you remember your negative feelings more easily. Slouching reduces blood flow and lessens your focus as you sit.

What Are Some Quick Fixes for Poor Posture While Sitting at a Desk?

Consider using a more ergonomic chair, such as an exercise ball or one with more space for your leg muscles.

From my experience, positioning your screen level to your head relaxes the shoulders.
