Today I am writing a bit about why we need oxygen 

We need oxygen because it helps our bodies make energy. Every cell in the body needs energy to do its job, such as helping us move, think, grow, heal, and stay alive. Oxygen works with the food we eat, especially glucose, so our cells can release energy through a process called cellular respiration.

When we breathe in, oxygen enters our lungs and then moves into our blood. The blood carries oxygen around the body to all our cells. Inside the cells, oxygen helps turn food into a form of energy called ATP, which powers important body activities like heartbeat, breathing, muscle movement, and brain function.

Without enough oxygen, cells cannot make enough energy. This can make a person feel weak, dizzy, or confused, and if oxygen is missing for too long, cells can become damaged or die. That is why oxygen is essential for life.

When we exercise, our muscles work harder and need more energy. To make this extra energy, our cells need more oxygen. This is why we start breathing faster and deeper, because our lungs are bringing more oxygen into the body and removing more carbon dioxide.

Our heart also beats faster during exercise. This helps pump oxygen-rich blood to the muscles more quickly so they can keep moving. After exercise, we may keep breathing heavily for a little while because the body is still bringing in oxygen and helping the muscles recover.

Today I am sharing some information about how breathing works.

When you inhale, the diaphragm contracts and moves downward, making more space in the chest. This lowers pressure in the lungs, so air flows in.

When you exhale, the diaphragm relaxes and moves upward. The chest space becomes smaller, pressure increases, and air is pushed out.

There is also gas exchange this happens in the alveoli. Oxygen from inhaled air passes through thin alveolar walls into the bloodstream. At the same time, carbon dioxide moves from the blood into the alveoli so it can be breathed out.

Why does it matter, well out respiratory system works closely with the circulatory system. The lungs supply oxygen to the blood, and the heart pumps that oxygen-rich blood around the body. Without oxygen, cells cannot efficiently release energy from food.

There are some common respiratory conditions such as:

Asthma

Bronchitis

Pneumonia

Chronic obstructive pulmonary disease

Lung infections

Allergies affecting the airways

Then of course there is cancer and not just lung cancer but others. The cancers that affect the respiratory system are the following:

Lung cancer – the most common respiratory-system cancer; it starts in the lung tissue and can make breathing difficult.

Tracheal cancer – affects the windpipe, which carries air to and from the lungs.

Bronchial cancer – affects the bronchi, the large airways that branch into the lungs.

Laryngeal cancer – affects the voice box and can impact breathing, speaking, and swallowing.

Throat/pharyngeal cancer – can affect the upper airway and may interfere with breathing and swallowing.

Mesothelioma – a cancer of the lining around the lungs, often linked to asbestos exposure.

Metastatic cancer in the lungs – cancer that starts elsewhere in the body but spreads to the lungs.

Today we are looking at something most people have used and something I use daily that’s sticky tape.

The term “sticky tape” is commonly used in places such as Australia and the UK, while in the US people often say, “Scotch tape” or “transparent tape.” Over time, sticky tape evolved into many specialised forms, including masking tape, packing tape, electrical tape, double-sided tape, medical tape, and duct tape.

It was invented in the early 20th century as a practical solution to an everyday industrial problem: how to seal, mask, or hold materials together cleanly without using messy glue, string, or pins.

In the 1920s, 3M employee Richard Gurley Drew was working with car manufacturers, who needed a better way to create neat two-tone paint jobs on automobiles. Painters were using heavy paper and adhesive methods that often damaged the fresh paint or left uneven edges. Drew developed a pressure-sensitive masking tape in 1925, which could stick temporarily and be removed more cleanly.

A few years later, he helped create a clear version of pressure-sensitive tape. In 1930, 3M introduced Scotch® Cellulose Tape, a transparent adhesive tape made with cellophane. It became especially popular during the Great Depression because people used it to repair torn paper, mend household items, seal packages, and make things last longer rather than replacing them.

In short, sticky tape was invented not as a novelty, but as a clever industrial fix that became one of the most useful everyday tools in homes, schools, offices, and workshops.

This week we have a photo of my sister Jeanie, it is her birthday on Monday

As most of those who read my posts will know I have Parkinson’s Disease and since it is winter here, I am writing a bit about how the cold can affect people with Parkinson’s Disease

On thing I find is how hard it is for me to warm up once I become cold, I also feel the cold more. This is because Parkinson’s affects movement and can also affect the nervous system, which helps control body temperature.

I feel the cold weather makes my tremors more noticeable. I also find I suffer from shivering more. I have read that is common for some people to feel more tired because their body is working harder to stay warm and move comfortably.

Another common effect of cold weather is increased stiffness. When muscles are cold, they can tighten and feel less flexible. For a person with Parkinson’s, this can make rigidity, slowness, and everyday movements worse. Tasks such as walking, getting dressed, using buttons, or holding objects may take more effort than usual.

Mobility and balance can also be affected. In cold, wet, or icy weather, people with Parkinson’s may move more slowly and have a higher risk of falling. Stiff muscles, slower reactions, slippery paths, and bulky winter clothing can all make walking less steady.

To reduce these problems, it can help to dress in warm layers, keep hands and feet covered, warm up indoors before going outside, wear shoes with good grip, and allow extra time when walking in cold conditions.

The cold weather has prevented me from going for a walk the last couple of mornings, due to me finding it difficult to walk as my legs and feet feel heavy. I don’t feel safe as it is harder to pick me feet up and I am shuffling about.
