Diet, lifestyle, and underlying health factors can all impact sleep

Achieving a restful night’s sleep is more than just going to bed at the right time - it’s about building simple, effective habits that support your body’s natural rhythms and set the foundation for deep, restorative rest.

Experts say that adults need on average seven to nine hours' worth of sleep per night however this can feel challenging for lots of people.


Nutritionist at BlueIron, Cara Shaw has told GB News her approach for somebody struggling to sleep.

She said: "For anyone struggling with sleep, I would explore their diet, lifestyle, and underlying health factors to identify possible contributors to their sleep issues."

Cara laid out five tips for people to be able to sleep better.

Blood sugar balance

Varying blood levels can disrupt sleep causing night-time wake-ups or difficulty sleeping. The expert recommended: "Including protein (e.g. chicken, fish, lentils) and complex carbohydrates like whole grains in the evening meal. This will help to support serotonin production, a precursor to melatonin, the sleep-inducing hormone."

She added: "Some people may benefit from a small balanced snack before bed; like a small banana with almond butter, which can help to stabilise blood sugar overnight."

Iron levels and energy regulation

Iron is key for oxygen transportation and energy production with both factors impacting sleep quality.

The expert advised: "Add iron-rich foods to your diet like lean red meat, spinach, and legumes."

Stress and sleep hygiene

Creating a bedtime routine is an effective way of unwinding before bed. The expert suggested journaling, a short yoga flow and avoiding screens at least an hour before bed.

The key thing to focus on is relaxation. Cara suggested having: "Magnesium rich foods such as leafy greens, nuts, and seeds to promote relaxation."

Caffeine and stimulants

The expert advised reassessing your caffeine or stimulant intake. She said: "Stimulants can linger in the body for hours, reducing the quality of sleep. Reassess caffeine intake, especially in the afternoon."

Light and sleep hormones

The expert talked about our circadian rhythm and how critical it is for sleep. Our circadian rhythms are the 24-hour cycles that occur in our body, impacting our physical, mental and behavioural changes.

It's important to support this through our melatonin production. The expert advised: "Getting morning sunlight exposure to anchor your sleep-wake cycle and dimming lights in the evening plus avoiding blue light."

These tips can help support you while sleeping but for some people, it can be a mission to fall asleep. Listening to white noise or performing some breathing exercises are two examples of helping us fall asleep.
