Why Your Body Itches at Night

7. Insect Bites and Infestations

Insect bites or infestations, such as those from bed bugs or fleas, can be a hidden cause of nighttime itching. These pests are often more active at night, and their bites can lead to persistent itching and discomfort. Bed bugs, in particular, are notorious for their nocturnal feeding habits and can cause significant sleep disruption. Identifying and addressing infestations through thorough cleaning, pest control measures, and sometimes professional extermination can eliminate this source of itching and restore restful sleep.

8. Dietary Influences and Deficiencies

Dietary factors and nutritional deficiencies can also play a role in nighttime itching. Certain foods, such as those high in histamines, can trigger itching in susceptible individuals. Additionally, deficiencies in essential nutrients like vitamin D, vitamin B12, and omega-3 fatty acids can affect skin health and lead to dryness and itching. Maintaining a balanced diet rich in vitamins and minerals, along with avoiding known dietary triggers, can improve skin condition and reduce the likelihood of nighttime itching.
