Why do I wake up freezing and unable to get warm?

There are a few reasons why you might wake up freezing and unable to get warm.

* Hypoglycemia (low blood sugar). When your blood sugar levels drop, your body can't produce heat as effectively. This can lead to feeling cold, even if the room is warm.

* Anemia. Anemia is a condition in which your body doesn't have enough red blood cells. Red blood cells carry oxygen to your tissues, so if you're anemic, your tissues won't get enough oxygen and you may feel cold.

* Hypothyroidism. Hypothyroidism is a condition in which your thyroid gland doesn't produce enough thyroid hormone. Thyroid hormone helps to regulate your body's metabolism, and if you have too little of it, your metabolism can slow down and you may feel cold.

* Menopause. Women who are going through menopause may experience hot flashes and night sweats, which can disrupt sleep and make you feel cold.

* Certain medications. Some medications, such as beta-blockers and calcium channel blockers, can cause your blood vessels to narrow, which can lead to feeling cold.

* Medical conditions. Some medical conditions, such as diabetes, heart disease, and cancer, can cause you to feel cold.

If you're experiencing chronic cold spells, it's important to see your doctor to rule out any underlying medical conditions. Your doctor can also recommend ways to manage your symptoms and stay warm.

Here are some tips for staying warm at night:

* Wear warm pajamas.

* Use a heating pad or electric blanket.

* Take a warm bath or shower before bed.

* Have a hot drink before bed.

* Eat a healthy diet and get regular exercise.

* Get enough sleep.
