Bed bug

Bed bug bites can be very itchy, leading to the strong urge to scratch it until the itch goes away. And because bed bugs often bite in the middle of the night when we’re asleep, we unconsciously scratch them, leading to flesh wounds in the morning.

Expanding redness around the wound, increased swelling, tender bumps that are warm to the touch are just some symptoms of a bacterial skin infection. Some common skin infections include cellulitis, Impetigo, and boils.

Allergic reaction to bites

An allergic reaction to bed bug bites is one of the more serious health risks of having a bed bug infestation. Because bed bugs bite to feed on their host’s blood, some people might experience severe allergic reaction after being bitten, leading to life-threatening situations.

Anaphylactic shock is often life-threatening and requires immediate medical attention.

Sleep deprivation

Emotional anxiety caused by stress can lead to unhealthy behavior and habits like drinking and smoking, may impact on our immune system and its ability to fight off antigens, making us more prone to all kinds of infections. Stress can also increase heart rate and blood pressure, as well as affect our digestive system. All this combined can increase the risk of catching harmful diseases.
