How long can you stay naked without feeling uncomfortable? Most of us are not comfortable with our own bodies and thus, do not like sleeping naked. But it is a scientifically proven fact that sleeping naked has its benefits.

If you are sleeping without clothes, you are bound to have better sleep and lower levels of stress. Here are 7 amazing benefits of sleeping naked every night!

1. IMPROVES SPERM QUALITY
A new research reveals that men who sleep naked have better quality sperm. Tight boxers can increase the temperature of the testicles, which can cause the quality of a man's sperm to decrease. Ditching them in favour of loose underwear during the day and nothing at night can bring about a 25pc increase in sperm quality, according to the research. This study supports the notion that keeping the testes cool is better for sperm function.

2. DEEPER SLEEP
Are you tormented by insomnia? Try sleeping naked for a change. Sleeping naked will help in maintaining the ideal body temperature to fall asleep. This will help you in having a deep and sound sleep without having to worry about drastically reducing the temperature of your air conditioner.

3. HIGHER RATE OF METABOLISM
When you are sleeping deeply, your body's rate of metabolism rises. So basically you burn fat faster even while you are sleeping.

4. HIGHER OXYTOCIN
Oxytocin is a feel good hormone that is produced in the body during sexual intercourse. Sleeping naked gives a natural boost to your oxytocin level making you feel really sensual and happy.

5. SLOWS DOWN AGEING
When you sleep with clothes, your body gets warm and this interferes with the release of Human Growth Hormone that repairs skin cells. Sleeping without clothes keeps your body cool and also slows down the process of ageing. As your body produces more Human Growth Hormone, you will have fewer wrinkles.

6. IMPROVED BLOOD CIRCULATION
When you are lying down flat, your blood circulation slows down because there is no pull of gravity. Plus, the elastic bands and drawstrings of your night clothes further obstruct blood circulation. Sleeping naked can thus help your blood flow freely.

7. YOU STAY SLIM
When you have lower levels of stress hormone called cortisol and higher rate of metabolism, you will end up losing accumulated fat. It is a fact that people who sleep naked have lesser percentage of belly fat.
