Five nutrition hacks to recover from a bad night's sleep

A night of poor sleep can make the following morning feel significantly harder than usual — thoughts move more slowly, the body feels heavy, and even straightforward tasks can demand more effort than they ordinarily would.

Whilst nothing truly replaces a full night of quality sleep, certain foods, nutrients, and lifestyle choices may help support brain function on the occasions when rest has fallen short.

From hydration and coffee to antioxidant-rich fruit and targeted supplements, small nutritional decisions can offer a meaningful boost to focus, memory, and mental clarity when the brain is struggling to keep pace.

A brain surgeon's personal toolkit

Dr Rupa Juthani, a US-based neurosurgeon specialising in pituitary and skull base tumour surgery as well as Gamma Knife radiosurgery, has shared five science-backed strategies she personally relies upon to maintain cognitive sharpness after a night of insufficient sleep.

In an Instagram video posted on 2 May, she said: "Middle of the night brain surgeries are exhausting, these five things can help you recover and be your best the next day."

1. Creatine for brain recovery

Dr Juthani recommends creatine as a tool for supporting brain recovery following poor sleep. She takes creatine daily to support both brain health and muscle recovery, but on days after inadequate rest, she incorporates an additional one-time higher dose into her routine.

Citing research, she notes that a single high dose may help counteract some of the cognitive decline associated with sleep deprivation.

"In addition to using creatine daily to support brain health and muscle recovery, I use a single high dose after a night of poor sleep, based on studies showing benefit under these conditions: Creatine in a single high dose may reverse sleep-deprivation induced decline in brain function. More studies are needed to determine doses and who might benefit the most," she explained.

2. Hydration

Dr Juthani places particular emphasis on staying well hydrated, especially for those who take creatine regularly.

The supplement draws water into the muscles and can increase the body's overall fluid requirements, making consistent water intake all the more important for supporting its effects and maintaining general wellbeing. "Hydration is key, especially if using creatine," she noted.

3. Blueberries for a quick brain boost

According to Dr Juthani, blueberries may offer an immediate uplift to both memory and cognitive function, in addition to their well-documented benefits as a rich source of fibre and antioxidants.

She also recommends pairing protein-rich foods with fibre-rich options on days following poor sleep, as the combination can help sustain sharper cognitive performance throughout the day.

Citing a randomised controlled trial, she explained: "Blueberries may provide an immediate boost to your memory and cognition, in addition to its fibre and powerful antioxidant benefits.

"I usually practice intermittent fasting, but when I am sleep deprived I pair protein and fibre rich foods to stay sharp.

"This study was a randomised controlled trial showing cognitive and vascular benefits from the equivalent of a handful of blueberries particularly in ageing patients."

4. Multivitamins and omega-3s

Dr Juthani advises taking vitamin D alongside a multivitamin containing B vitamins and omega-3 fatty acids as a means of supporting brain function and overall cognitive health.

She regards each of these nutrients as playing a meaningful role in bolstering memory and focus. "Vitamin D, omega 3s, and B-vitamins all play an important role in memory," she said.

5. Black coffee for cognition and antioxidants

The neurosurgeon highlights black coffee as a tool that goes beyond simple alertness. According to Dr Juthani, coffee enhances cognitive function not only through the stimulating effects of caffeine but also by way of the antioxidants it contains, which may help support functional connections within the brain — contributing to quicker reaction times, improved alertness, and better memory.

Importantly, she points to research suggesting that these brain-boosting benefits appear to be specific to black coffee, and that adding sweeteners or dairy may reduce or negate some of those effects.

The benefits also appear to be tied to coffee itself rather than other sources of caffeine such as tea.

"Coffee enhances cognitive function and performance, partially by its stimulant effects but also by enhancing functional connections in the brain, resulting in more rapid reaction times and memory.

"But coffee does more than just enhance alertness and mental performance. Data has shown that drinking black coffee is correlated with healthy brain ageing.

"This effect seems to be eliminated with the use of sweeteners or additives like milk. The benefit also seems specific to coffee, not other forms of caffeine like tea," she explained.

Sleep remains the most powerful recovery tool

Despite outlining these supportive strategies, Dr Juthani is clear that sleep itself remains the single most effective means of cognitive recovery.

The hacks she describes are intended to provide occasional support during periods of sleep deprivation and should never be regarded as a substitute for proper rest.

"Sleep is the most powerful way to recover – and prevention is always better than treatment," she concluded.
