You live in your body every single day, but how well do you actually know it?

You should know what is normal for your body.

Your usual energy levels, appetite, bowel habits, sleep pattern, skin, weight fluctuations and other everyday changes. That makes it easier to notice when something is genuinely different.

You should know your blood group.

And if possible, know your genotype, allergies and any important medical history.

Know what medications you take and why you take them.

Don't just say, “I take the blue one.” Know the name.

Know what your body reacts badly to.

Certain foods, medications, skincare products or environments may trigger reactions. Don't keep discovering this the hard way.

Know your menstrual cycle if you have one.

Know roughly when your period comes, how long it usually lasts and what symptoms are normal for you.

Know your family medical history.

Ask questions. High blood pressure, diabetes, certain cancers and other conditions can run in families, and knowing your history can help you have more informed conversations with a healthcare professional.

Know what your normal body temperature, blood pressure or resting heart rate tends to be if you have access to ways of checking them.

Most importantly, know when something has changed.

A new lump.

Unexplained bleeding.

Persistent pain.

A wound that isn't healing.

Sudden changes in your weight.

Breathing difficulties.

A symptom that keeps coming back.

Don't diagnose yourself from TikTok, but don't ignore your body either.

And please don't wait until something becomes unbearable before seeking medical advice.

Your body gives you information every day.

Pay attention to it.
