Why You’re Always Cold, Tired and Losing Hair — and What Your Thyroid Might Be Trying to Tell You

You’re rugged up in layers while everyone else seems fine. Your hair is thinning — not dramatically, but enough that you’ve noticed. And no matter how much sleep you get, you wake up feeling like you haven’t rested at all.

Sound familiar?

These symptoms are incredibly common — and they’re often brushed off as just being “run down” or “getting older.” But when they show up together, they can be signs that your thyroid isn’t functioning the way it should be.

What Does Your Thyroid Actually Do?

Your thyroid is a small, butterfly-shaped gland that sits at the front of your neck. Despite its size, it plays a massive role in how your entire body functions. It produces hormones that regulate your metabolism, body temperature, energy levels, mood, menstrual cycle, and even how quickly your hair grows.

When your thyroid is underactive (a condition known as hypothyroidism), it doesn’t produce enough of these hormones — and that’s when things start to slow down. Your energy drops, your body temperature dips, and your hair can begin to thin or fall out more than usual.

The Symptoms That Might Point to Your Thyroid

Thyroid conditions are surprisingly common in women, yet they’re frequently missed or dismissed. Here are some of the signs that your thyroid might need attention:

· Persistent fatigue that doesn’t improve with rest

· Feeling cold when others around you are comfortable

· Hair thinning or loss, particularly at the outer edges of your eyebrows

· Unexplained weight gain or difficulty losing weight

· Brain fog, poor memory or trouble concentrating

· Dry skin and brittle nails

· Constipation

· Low mood or increased anxiety

· Irregular or heavy periods

· Puffy face or swollen neck

If you’re nodding along to several of these, it may be worth looking deeper — especially if you’ve been told your thyroid is “fine” based on a standard blood test.

One of the most frustrating things I hear from women in my clinic is: “My GP said my thyroid is normal.” And technically, they may be right — based on the one marker that was tested.

Most standard thyroid tests only check TSH (thyroid stimulating hormone). While TSH is useful, it doesn’t tell the whole story. A more comprehensive picture includes looking at Free T4, Free T3, reverse T3, and thyroid antibodies — markers that can reveal whether your thyroid is actually converting and using its hormones effectively, and whether there’s an autoimmune component at play (such as Hashimoto’s thyroiditis).

There’s also the issue of reference ranges. Your results might fall within the “normal” range but still be far from optimal. This is something I explore in depth in naturopathic consultations — because how you feel matters just as much as what the numbers say.

Several factors can contribute to thyroid dysfunction, and many of them are things women encounter every day:

· Chronic stress and elevated cortisol, which can suppress thyroid function

· Nutrient deficiencies — particularly iodine, selenium, zinc, iron, and vitamin D

· Gut health issues, as a significant portion of thyroid hormone conversion happens in the gut

· Environmental toxins and endocrine disruptors found in everyday products

· Hormonal shifts during perimenopause, postpartum, or times of high stress

Understanding these contributing factors is key because it means that supporting your thyroid isn’t just about medication. There are real, evidence-based steps you can take — through nutrition, lifestyle adjustments, and targeted supplementation — to give your thyroid the support it needs.

As a naturopath, my approach to thyroid health goes beyond just looking at your TSH. I take the time to understand your full health picture — your symptoms, your history, your lifestyle, and what’s actually happening at a cellular level.

This might include:

· Comprehensive thyroid testing to identify what’s really going on

· Nutritional support tailored to your individual needs

· Gut health assessment — because your gut plays a major role in thyroid hormone conversion

· Stress management strategies to reduce the cortisol burden on your thyroid

· Herbal and nutritional supplementation where appropriate

· Working alongside your GP or endocrinologist to ensure you’re getting the best of both worlds

If you’ve been brushing off your symptoms or you’ve been told everything is “normal” but you still don’t feel right, trust that instinct. Your body is communicating with you — and understanding what your thyroid is trying to tell you could be the first step toward feeling like yourself again.
