Why does my body feel like it's being pricked by needles and itch at night while sleeping, and what should I do about it?

In general, sensations of pricking or itching in the body during sleep at night may be caused by various factors, including hormonal changes, dry skin, neurodermatitis, folliculitis, urticaria, and other conditions. If abnormal symptoms occur, it is recommended to seek timely medical evaluation at a hospital to identify the underlying cause and receive targeted treatment. Specific analyses are as follows:

1. Hormonal Changes

At night, levels of hormones such as cortisol in the body decrease, which may weaken the skin's protective barrier and increase sensitivity to external stimuli, leading to itching. Maintaining good sleep habits and avoiding staying up late can help regulate hormone levels.

2. Dry Skin

In winter or low-humidity environments, dry indoor air at night can cause the skin to lose moisture, damaging the stratum corneum and exposing nerve endings, thereby triggering itching. Keeping indoor humidity at an appropriate level, using mild and non-irritating moisturizers, avoiding excessively hot water when bathing, and minimizing the removal of natural oils from the skin surface are recommended.

3. Neurodermatitis

Neurodermatitis is often triggered by emotional fluctuations or anxiety. As the mind relaxes before sleep, the sensation of itching may become more pronounced, possibly accompanied by redness, swelling, and papules. Doctors recommend first adjusting mental state and avoiding excessive tension and anxiety. Additionally, topical treatments such as mometasone furoate cream, fluticasone propionate cream, or hydrocortisone butyrate cream may be used under medical guidance for symptomatic relief.

4. Folliculitis

When hair follicles become blocked and bacteria proliferate, follicular inflammation may develop, causing papules and itching. Lower indoor temperatures at night or frictional irritation during sleep may exacerbate the itching. It is important to maintain skin cleanliness. If necessary, doctors may prescribe topical antibiotic ointments such as erythromycin ointment, clindamycin phosphate gel, or mupirocin ointment for localized treatment.

5. Urticaria

Urticaria results from abnormal immune system reactions. When the body encounters allergens, the immune system releases inflammatory mediators that trigger skin symptoms such as redness, swelling, and hives. Doctors generally recommend medications such as montelukast sodium tablets, compound glycyrrhizin tablets, or diphenhydramine hydrochloride tablets for treatment, along with avoiding exposure to known allergens.

It is advisable to pay attention to bodily responses in daily life. If an allergic reaction is suspected, contact with or consumption of potential allergens should be stopped immediately. Additionally, maintaining clean and dry skin helps reduce the risk of developing skin disorders.
