Kipping for five hours or less increases your risk of obesity by 15%, according to a US study. Fluctuations in ghrelin and leptin, the hormones that regulate metabolism and appetite, are to blame, says Dr Leschziner. Have air-con in your room? Freeze them out by setting the temperature below 18°C: It triggers “non-shivering thermogenesis” for overnight weight loss.
People who get only five hours of sleep typically have an increased risk of cardiovascular disease and can become insulin resistant, according to professor Adrian Williams of The London Sleep Centre. Work to blame? Walk away. No, don’t quit: A study found walking for 30 minutes, five days a week, can prevent and reverse insulin resistance.
While there are proven ways to increase your levels of human growth hormone marginally (heavy squats, for example), 60 to 70% of your HGH – which is responsible for everything from metabolism to hair growth – is produced during sleep. And a Harvard study linked insufficient sleep to less efficient production. There’s no way around this one, ladies.
Your body also uses sleep to eliminate toxins from the skin, says Dr Guy Meadows, co-founder of The Sleep School in the UK. People who skimp on sleep show signs of premature skin ageing, reports the University Hospitals Case Medical Center in the US. Cleanse, then apply a good-quality moisturiser and sleep on a silk pillowcase to minimise wrinkles.
