Many people feel a little blue during fall and winter. For some, it has to do with summer ending and the change in weather, signaling that vacation is over.

For others, the symptoms go far beyond feeling sad that summer is over. These people suffer from Seasonal Affective Disorder (SAD), a form of depression that accompanies changes in the seasons. People with good mental health throughout most of the year will start showing depressive symptoms in the fall and winter months.

Symptoms of Seasonal Affective Disorder (SAD)

This kind of depression is easily dismissed because it starts out mild but worsens as the season progresses. Its signs and symptoms are typical depression symptoms such as low energy, loss of interest in activities that you previously enjoyed, and changes in appetite and sleep patterns.

SAD doesn’t actually appear in the Diagnostic and Statistical Manual (DSM) – the big book therapists use to diagnose patients. For this reason, many experts refer to it as a form of depression with a seasonal pattern. However, they recognize that it’s a real condition that cannot be dismissed as “winter sadness.”

How to Beat the Blues

Serious cases of SAD require medication, psychotherapy, and phototherapy. However, and here’s the good news, less serious cases can be resolved through lifestyle and environment changes.

Brighter Lights

The cause of “winter blues” remains unknown, but scientists think that the decrease in daylight disrupts the body’s internal clock, leading to feelings of sadness.

This is why you should get as much daylight as possible. Open the blinds and sit closer to the windows.

Artificial light can also be very useful in remedying this situation. And get this, sitting next to a light box for 30 minutes every day is just as effective as taking medication.

You might also consider investing in a dawn simulator, a device that causes your bedroom lights to gradually brighten in the morning. It’s especially useful for people who struggle to wake up in the morning.

Eat Better and Exercise

Poor food choices can make SAD much worse. Coffee and soda may make you feel better for a while, but ultimately make your symptoms worse.

Eat regular meals to stabilize your blood sugar and prevent cravings. Add tryptophan-rich foods such as oats, nuts, and seeds to your diet. Tryptophan is necessary for the production of serotonin, a chemical that regulates mood.

Walking fast for about 35 minutes a day, five days a week, can relieve symptoms of mild to moderate depression. It’s even better if you can exercise under bright light as opposed to ordinary light.

Go Outside

It’s hard not to feel blue when you spend all your time indoors. Get into the habit of spending time outdoors even when it’s chilly. Take a walk or something!

Many people feel a little blue in the fall and winter, so it’s not all in your head. In fact, we could all benefit from brighter lights, a better diet, exercise, and spending more time outdoors during these months.

Do you wake up feeling tired and groggy even though you’ve had a full night’s sleep? Your internal body clock / circadian rhythm might not be working properly.

The circadian rhythm regulates your level of sleepiness or wakefulness throughout the day. When it’s working properly, you should wake up feeling energized and ready to conquer the world!

An out-of-whack body clock doesn’t just make you tired. It also disrupts your brain’s wave patterns, hormone production, and cell regulation. This disruption has been linked to depression, obesity, cancer, and cardiovascular disease.

Thankfully, it is possible to reset your circadian rhythm as long as you can figure out what is throwing it off.

Do you have a regular sleep schedule?

Do you go to bed and get up at around the same time every day? An erratic sleep schedule throws off your body clock.

If you want to wake up feeling refreshed, you need to pick a bedtime and a wake-up time. Don’t just go to bed whenever you feel like it.

Having a fixed bedtime also helps you wind down. You might not always go to bed on time, but the realization that it’s “past your bedtime” helps you to relax and get ready for bed.

Do you wind down before bed?

How do you prepare for bed? If you work or watch TV up until the minute you fall asleep, your brain doesn’t get a chance to wind down.

To sleep better, you need to find a way to let your mind know that it’s time to gear down and to set aside any anxious or worrisome thoughts before bedtime.

You need a pre-sleep ritual or routine.

It could be anything from taking a warm bath to reading a book, as long as it helps you relax.

Your body and mind need 30 to 60 minutes of pre-sleep time. During that time, you should avoid doing anything stimulating, such as working or browsing the internet.

Do you turn off the lights and electronics?

This seems obvious, but many people still go to sleep with the lights, TV, computer, or phone on.

Your body’s clock responds to light. This is why you’re most alert when the sun is shining and most tired when it’s dark outside.

Artificial light, whether from indoor lights or from the phone, confuses your body and makes it difficult for it to determine whether it’s day or night.

If you go to bed expecting to wake up feeling rested and energized but wake up feeling groggy, you may need to reset your body clock. Start by analyzing your pre-sleep and sleep habits using the above pointers, and then make any necessary changes.

There’s no shortage of nutrition experts who believe that late night snacking is bad for your health and causes weight gain. According to them, all late night snacks are a complete no-no, even healthy ones.

On the flip side, some experts believe that late night snacking increases your metabolism and helps burn calories. To them, a calorie is a calorie no matter when you eat it. So, who’s right?

Bad News for Late Night Snackers

Multiple nutrition studies have proven that eating at night causes weight gain as well as negative hormonal and metabolic changes. This applies for healthy eaters as well.

Your body has an internal clock, which typically wants you to be awake during the day and asleep at night. For this reason, the food that you eat during “normal waking hours” is metabolized much faster than food eaten at 3:00 am when your body clock is in sleep mode. Your liver also absorbs fats much faster during the day, so when you eat at night most of that fat gets stored causing weight gain.

What Time Of The Night Should You Stop Eating?

Consider having your main meal before 3:00 pm; so go ahead and have a hearty lunch. After 3:00 pm, most of the hormones that follow your natural circadian rhythm, your body clock, begin decreasing as your body prepares for the end of the day. Additionally, most experts do not recommend eating after 7:00 pm because most late-night munching has more to do with cravings than hunger. This doesn’t mean you should starve yourself if you’re legitimately hungry and didn’t have a chance to eat before 7:00 pm.

But, If You Do Have a Late Night Snack . . .

Obviously, all late night snacks are not created equal. If you can’t fall asleep because you’re hungry and have a bad case of the munchies, eat something that isn’t too sweet, salty or rich and has fewere than 150 calories. Have a piece of fruit, a glass of low fat milk or low fat yogurt (make sure it isn’t loaded with sugar), one or two squares of dark chocolate or a high fiber snack bar (again, check its sugar content).

Late night snacks to avoid include cereal, ice cream, fries, burgers, soda – basically anything that is high in sugar and fat. And stick to foods that don’t trigger overeating, like chips and cookies – anything you know you can’t stop eating once you’ve opened the floodgates! Even better, don’t keep junk food in the house to avoid late night temptations altogether.

If you must eat late at night, have a small, healthy snack. You’ll sleep better and your body (especially your waistline) will thank you for it!

What would you give to wake up feeling energetic, well rested and ready to conquer the world every single day?

It goes without saying that your morning sets the tone for the rest of the day. The more productive your morning, the likelier you will have a more productive rest of the day.

Studies by the American Psychological Association show that morning people are healthier, happier and often more successful than night owls! Remember the saying, “early to bed, early to rise . . .”, well, it’s actually true.

Additionally, it seems that morning people are more likable too! They score higher on agreeableness, cooperativeness and conscientiousness, and they procrastinate a lot less.

It’s Biology!

Let’s clear up some misconceptions first. Evening people are not lazy. Like everyone else, they are at the mercy of their internal body clocks / circadian rhythms. This rhythm is actually ingrained into the cells while still in the mother’s womb.

Although we might feel powerless against our respective biological clock, both larks and owls are capable of being creative and productive in their “off hours”.

Your circadian rhythm also changes as you get older. Most children are larks, most young people in their 20s are owls and most people above 50 are larks.

In addition, only about 25% of people are morning people. About 50% are somewhere in the middle, and the other 25% are evening people. So, you’re not alone in your struggle to not hit the snooze button.

Override Your Biology!

Hitting the snooze button multiple times is a sign of sleep deprivation and has little to do with your body clock. So create a consistent sleep schedule that involves going to bed early and waking up early.

If you decide to go to bed earlier in the evening, start by adjusting your bedtime by 15 minutes at a time. Before you know it, you’ll be going to bed earlier than you ever thought possible. Remember to adjust your sleep pattern in small increments because your body clock will fight any drastic changes.

Light shifts your circadian rhythm, so put away your electronics at least an hour before bed. This gives your body enough time to wind down making it easier to fall asleep when you finally do go to bed. If you need a little more help falling asleep, take melatonin 30 minutes before bed.

Exposing yourself to super bright light in the morning (about 2000 lux) lets your body know that it’s time to get going. The light calibrates your body clock, boosts your energy and makes it a lot easier for you to fall asleep in the evening. The light can be natural or artificial so long as it’s really bright.

Just because you were born an evening person doesn’t mean that you have to endure it for the rest of your life. With a few well-timed changes, you can train your internal clock into making you a morning person!
