Sweating in the night due to poor cooling in the room or wearing blankets is understood and we all suffer from it but night sweats are different. When everything like the room temperature is fine but you end up sweating, it is termed as night sweating. Many people wake up in the middle of the night fully drenched in sweat as if they have just come out of a shower! Once in a blue moon, it is okay and may be due to overworking or extreme tiredness but in most cases, there are medical reasons behind this happening. We have mentioned the major causes of night sweats in this article. If you ever experience this situation, you can interpret the possible reasons behind that.

Overactive Thyroid

Excessive sweating and sensitivity to heat are the main symptoms of hyperthyroidism. Your thyroid gland controls your metabolism, so when it starts producing more hormones, your body becomes hyperactive. Your body temperature increases and you may feel hungry and thirsty, your pulse starts moving fast or your hands start trembling. If along with profuse sweating you happen to experience any of these symptoms, then it indicates that your thyroid gland is ill-functioning and you must consult a doctor.

Low Blood Sugar

Do you have diabetes? If yes, then night sweats may have a connection with your condition. When you check your blood glucose at bedtime, it is stable but it suddenly drops after sleeping. This may be due to your overworked day or late in the evening exercise or eating very late at night. If you use insulin to control your diabetes, then hypoglycemia may be responsible for this condition. Eat something when your glucose lowers down to below 140 mg/dL before bedtime or if it falls in a few hours.
