Sometimes I don’t sleep very well. I wake up at 4am and then basically stay awake until morning. So I was thrilled to try out the Zeez Sleep Pebble for London Private Medical Services. It is a totally new concept replicating your body’s natural sleep electrical signals. I have slept deeply every night. Try it and you will love it.
Have you been sleeping since SARS-CoV-2 appeared? Has the stress of dealing with the virus and the loneliness of isolation made it harder to fall asleep, increased night-time wakefulness and lead to less restful slumber? Almost half of us are sleeping worse now than before lockdown, levels of depression and anxiety have skyrocketed, and women are more affected than men.
Poor sleep damages our physical and mental health, and this virus raises a particular concern – the effect of disturbed sleep on our immune system.
We need a strong immune system to maximise our chance of resisting and overcoming a viral attack. A single night of disrupted sleep reduces our T cells, the first line of defence against viral invaders, by 75% and reduces antibody production by 507. What to do to improve the quality of our sleep when we are already eating well, exercising, spending time outside, and following normal sleep hygiene? Sleeping pills are not a solution. They tend to shut down brain activity rather than encouraging deep sleep, lightening our sleep quality even where they prolong sleep duration.
What about tech? Several companies already use sound or powerful magnetic fields to stimulate deep sleep. We talked to Anna McKay of Zeez Sleep, a UK start-up whose under-the-pillow sleep devices use extremely low power electrical pulses to prompt a good sleep pattern throughout the night. Anna explained that when we are stressed, our brain activity is too fast for sleep. We think, we process, our amygdala is triggered, and our nervous system stays in sympathetic “alert” mode, rather than switching into parasympathetic mode (rest and recovery). This inappropriate brain activity can persist long after the original stressor has disappeared. That’s the problem that Zeez Sleep has sought to address.
Anna and engineer Steve Walpole spent a decade developing and testing their Zeez Sleep Pebble, a small device designed to generate tiny electrical pulses of the same frequency and power as those produced naturally by the brain of a good sleeper during relaxation and deep sleep, through four sleep cycles (6¾ hours).
Anna says that the main factor in whether or not Zeez has a positive effect seems to be the biochemistry of the brain. If we are dehydrated, or too low in essential minerals, the Zeez can’t help, but if we are properly nourished the Zeez is likely to help most of us, however severe or longstanding our poor sleep.
We have tried in Zeez’s approach at London Private Medical Services and had great results. Good sleep is one of the best things for our health, longevity and emotional wellbeing. To find out more visit www.zeez.org.uk.
