Do these mental health products even do anything?

Summary by Krater

The creator reviews five popular wearable devices marketed for sleep improvement, anxiety relief, and mental wellness — Cove, Lief, Mendi, NeoRhythm, and CalmiGo — testing them for weeks and concluding that none of them justify their high prices or work as advertised.

Answers: Are wearable devices like Cove, Lief, Mendi, NeoRhythm, and CalmiGo effective for stress and sleep?

• wearable stress relief devices
• EEG neurofeedback headbands
• Vagus nerve stimulation
• heart rate variability tracking
• Pulsed Electromagnetic Field therapy

What it concludes

• Cove discontinued its product line and stopped selling directly to consumers after promising to change lives for two years.
• Lief has poor customer service, a buggy app that crashes, and subscription pricing models that make it cost over $1,200 a year.
• Mendi requires the user to focus on a game to make a ball rise, but scores seem arbitrary and do not reflect real brain improvements.
• NeoRhythm is an expensive plastic piece with an LED light that provides no feedback and showed no positive impact on sleep.
• CalmiGo is a breathing device that vibrates, but it is priced too high for what is essentially a physical breathing guide.
• Wearable stress and sleep tracking gadgets often rely on placebo effects and expensive marketing rather than proven efficacy.
