Nausea and vomiting are common experiences in early pregnancy, a condition often called “morning sickness” or, more accurately, nausea and vomiting of pregnancy (NVP). This affects roughly 70% of expectant mothers worldwide, significantly impacting daily life and well-being. For those seeking non-pharmaceutical options, sickness bands have become a popular, easily accessible remedy. These bands are a form of acupressure wristband used as a drug-free way to manage symptoms. The central question for many is whether these simple bands offer genuine relief from pregnancy-related nausea.
The Acupressure Principle: How Sickness Bands Target Nausea
Sickness bands function by applying continuous pressure to a specific point on the inner forearm. This location is known in traditional Chinese medicine as the Neiguan point, or more commonly, the P6 acupressure point. The theory suggests that stimulating this precise spot can modulate the body’s response to nausea triggers.
To find the correct location, place three fingers across the wrist, starting from the crease where the hand joins the arm. The P6 point is located beneath the edge of the third finger, positioned precisely between the two prominent tendons on the underside of the forearm. The band’s integrated button or stud is designed to maintain constant pressure on this area.
The proposed mechanism is that this pressure helps to interrupt or modulate the signals that travel between the digestive system, the nervous system, and the brain’s vomiting center. By stimulating the pericardium channel at the P6 point, the body may release natural chemicals, like endorphins, which can help to block or soothe the nausea-inducing signals. This action is believed to restore balance to the body’s internal systems.
Evaluating the Evidence for Pregnancy-Related Sickness
The scientific consensus regarding the efficacy of acupressure bands for NVP is complex, showing a mixture of positive and inconclusive results across various clinical trials. Some research has indicated that the use of acupressure bands on the P6 point can lead to a statistically significant reduction in the frequency and severity of nausea symptoms compared to a placebo or control group. These studies suggest that the bands may offer genuine physiological benefits for pregnant women experiencing mild to moderate NVP.
However, other comprehensive reviews and meta-analyses have found insufficient high-quality evidence to definitively conclude that P6 acupressure is consistently more effective than a sham or placebo intervention. The relief experienced by many users may be partially attributable to a strong placebo effect, given that the intervention is safe and easily administered. This variability in results means that the degree of benefit can differ significantly from person to person.
Acupressure has also been studied in cases of hyperemesis gravidarum (HG), a severe form of NVP characterized by extreme nausea and weight loss. One controlled trial found that P6 acupressure significantly decreased the severity of nausea and vomiting in women hospitalized with HG, even reducing the need for antiemetic medications. While the overall evidence is mixed, the bands are considered a promising, drug-free option that may help alleviate symptoms for a significant number of pregnant individuals.
Proper Usage and Safety Considerations for Relief
Correct placement is necessary to maximize the potential effectiveness of a sickness band. The Neiguan point, or P6, must be located precisely three finger widths down from the wrist crease, between the two central tendons. The band’s pressure stud must be centered directly over this spot on both wrists, as wearing a band on only one wrist may not provide the intended relief.
Acupressure bands are generally considered safe because they are non-invasive and do not rely on drug mechanisms. They are suitable for continuous wear by most pregnant women seeking a drug-free alternative for their symptoms. Side effects are typically minor and localized, such as slight skin irritation or temporary indentations at the pressure point. Rarely, wearing the bands too tightly for long periods may cause mild discomfort or swelling of the hands, which should prompt their temporary removal.
It is important to remember that while these bands offer a safe option for managing common NVP, they are not a substitute for professional medical care. Persistent or severe vomiting, especially if accompanied by weight loss, dehydration, or an inability to keep food down, may signal hyperemesis gravidarum. Any pregnant individual experiencing such severe symptoms should consult with a healthcare provider immediately for appropriate medical treatment and guidance.
