Do Women Need More Sleep Than Men?

Ms. Swati Kapoor, Dietitian/Nutritionist
Sleep is a fundamental requirement just like food and diet is for the functioning of a healthy body. Sleep even lays the ground work for a productive day ahead. Although most people need seven to nine hours of sleep each night to function well the next day, the National Sleep Foundation (NSF) 1998 Women and Sleep Poll found that the average woman aged 30-60 sleeps only six hours and forty-one minutes during the workweek.Studies show that women need more sleep than men. "Poor sleep certainly had a more profound effect on women than on men," says Edward Suarez, Ph.D., an associate professor at Duke University School of Medicine "One of the major functions of sleep is to allow the brain to recover and repair itself. During deep sleep, the cortex — the part of the brain responsible for thought, memory, language and so on — disengages from the senses and goes into recovery mode,” Jim Horne, director of the Sleep Research Centre at Loughborough University in England, told The Australian. "The more of your brain you use during the day, the more it needs to recover and, consequently, the more sleep you need. Women tend to multi-task — they do lot at once and are flexible — and so they use more of their actual brain than men do.”It follows that, if men used their brains more during the day, they would need a couple of extra hours too. "A man who has a complex job that involves a lot of decision-making and lateral thinking may also need more sleep than the average male — though probably still not as much as a woman,” Horne said. Getting the right amount of sleep is vital, but just as important is the quality of your sleep. Biological conditions of women are unique, like the menstrual cycle, pregnancy and menopause. All of these conditions can affect how well a woman sleeps. This is because the changing levels of hormones that a woman experiences throughout the month and over her lifetime, like the levels of estrogen and progesterone, have an impact on sleep.Lack of sleep is associated with increased risk of heart disease and obesity because lack of sleep causes increases secretion of the leptin hormone, which leads to excessive food cravings and may cause obesity. This even causes heart disease if left untreated. Lack of sleep leads to diabetes due to increased levels of the stress hormone, which stimulates the production of insulin and causes high blood sugar level, as well as more stress, depression, anxiety, and anger. However, these associations were weaker for men.So go to bed at the same time every day of the week, avoid heavy meals before bed, establish a relaxing bedtime routine, nap occasionally to make up for lost sleep, eat healthy and exercise daily.

You are too busy to eat and yet you are putting on weight. Are you getting enough sleep? Maybe this is what really sabotaging your weight and not your diet. Lack of sleep makes us crave more cups of coffee/tea or high sugar food like biscuits to perk us up. All this result in added calories. Besides if you are sleep-deprived, meaning that you are not getting good quality sleep, your metabolism will not function properly. Getting little or disturbed sleep causes hormonal imbalance which leads to weight gain. Sleep is very important.

Lack of sleep can lead to disturbed physiology of your body.

But this will only adds up to your weight so sleeping at least eight hours each night helps you in managing your weight.Hormonal imbalance: Lack of sleep or disturbed sleep increases the chances of getting obese. Many studies have shown that when you do not sleep enough it disturbs your hormonal balance by increasing the level of ghrelin hormone. Ghrelin is a hormone known for its affect on appetite and disturbed level of ghrelin hormone leads to increased appetite. Disturbed hormones level also lead to irritation or frustration feeling without any specific reason.Effects your metabolism: When your body is deprived of sleep your metabolism slows down and will not function properly.

If you have trouble sleeping try to have a routine of at least 30 minutes exercise during the day and keep pre-bedtime activities relaxing.

Insomnia & Sleep Hygiene

Dr. Suhasini Das, Psychiatrist
Sleep is an important component of our daily activities. It not only provides rest to our conscious mind, it is also the 'repair-time' for the body. Adequate sleep is essential for optimal functioning of the mind and body, especially those tasks that involve our cognitive resources like attention and concentration, learning and memory. Newborn infants can spend 16 to 18 hours per day in sleeping in early months of growth which decrease to 6 to 8 hours per day over years. However, with increasing studies, work pressure and responsibilities, we somewhere end up compromising on our sleep which then can have long term effects. Insomnia or difficulty in initiating or maintaining sleep is a common sleep disorder that is encountered very frequently. It can lead to daytime drowsiness, irregular sleep patterns, difficulty in attention and concentration, irritability, use of alcohol to fall asleep, night-time eating behaviours and overall decrease performance and productivity.Insomnia can be the primary disorder or it can be the manifestation of underlying psychiatric illness like depression (most common), anxiety disorders like generalized anxiety disorder, panic disorder, schizophrenia or due to substance use like alcohol, cannabis, cocaine etc. At times, insomnia can be due to certain medical conditions too.What is sleep hygiene?Sleep hygiene basically means doing activities that will help in maintaining sound sleep and full daytime alertness. Before starting any medication for insomnia, it is important that we have a good sleep hygiene. Some of the tips are mentioned below:DOs:Maintain regular sleep timingsMaintain regular exercise schedule Give yourself an hour to wind up before going to bedIf you are preoccupied with something, write it down on a paper and deal with in the morningKeep the bedroom quiet, dark and comfortable.DON'Ts:Avoid afternoon napsExercise just before sleep to wear yourself outEat heavy meal just before sleepDrink coffee or tea at nightSmoke cigarettesWatch television or laptop if you cannot get sleepUse alcohol to fall asleepEat in bedTalk on the phoneWatch the clock If all the above points are followed meticulously, you will notice a significant improvement in your insomnia. If however, your insomnia is chronic or lasting more than 1 month, it is advised that you seek professional help rather than self-medicating. It is also advised not take any sleeping pills without recommendation of doctor as side-effects like drowsiness, dependency, rebound irritability can develop on long-term use without proper guidance. 

Weight Loss Can Prevent and Cure Sleep Apnea

Ms. Swati Kapoor, Dietitian/Nutritionist
Apnea literally means "cessation of breath." If you have sleep apnea, your breath can become very shallow or you may even stop breathing while you are asleep. This state of not breathing can occur for 10 seconds in an hour, or in severe cases, the frequency of cessation of breath may further increase. The repeated episodes of apnea (lack of breathing) cause frequent night time awakening.Individuals with this disorder often complain of morning headaches, constant fatigue, and moodiness, and can fall asleep almost anywhere. More seriously, they can fall asleep even while driving. Obstructive sleep apnea is much more common in obese individuals. It is believed that the airway of obese individuals get obstructed by large tonsils, an enlarged tongue and increased fat in the neck. This presses airways when the pharyngeal (throat) muscles are relaxed during sleep. A person's neck circumference is a good predictor of sleep apnea. Obese men with a neck circumference of 17 inches or greater, and women with a neck circumference of 16 inches or greater are more likely to have sleep apnea.The worst part is that it is not only obesity that has an association with sleep apnea, but sleep apnea even results in poor sleep which increases food cravings. Lack of good quality sleep increases the chances of hormonal imbalance by increasing the level of ghrelin hormone. Ghrelin is a hormone known for its effects on appetite and disturbed levels of ghrelin hormone leads to an increased appetite which further leads to weight gain.Individuals with sleep apnea often have elevated blood pressure, high fasting glucose, and high cholesterol. Lack of sleep triggers stress hormones which stimulate the cell’s glycogen to get converted into glucose. This suppresses the function of insulin due to which blood sugar levels shoot up leading to diabetes and heart problems, all of which can worsen with further sleep deprivation. So, it's a vicious cycle. Obesity can lead to sleep apnea, which, itself, then causes derangements of hormones that control eating habits, leading to more weight gain, worsened blood pressure, glucose intolerance, worsened apnea and the cycle goes on and on.So, healthy eating with exercise leads to weight loss and not only helps in preventing such a vicious cycle of health problems but also helps in the cure of sleep apnea.
