The correlation between sleep and your mood is no secret. But you could still be tired and cranky regardless of how early you hit the hay. Studies have shown that even dim light, for example the glow from your TV, reading lamp or even your alarm clock, in the bedroom may increases cases of depression. This light decreases the production of the hormone melatonin. Without steady levels of melatonin, your normal sleep patterns can become disturbed. Think about this the next time you wake up on the wrong side of bed.
Solution: Do a lights-out check before bed. Turn off all the lights and try setting a sleep timer on the TV if that helps you fall asleep. Turn your alarm clock away from you.
5. Your Diet
The comfort food you grab when you’re in a bad mood could actually be the cause of your bad mood in the first place. Diets rich in trans and saturated fats have been linked to increased depression. Additionally, new studies indicate that these diets can negatively affect cognition. Junk food and fast food negatively affect the connections between your brain cells called synapses.
Solution: Look for foods packed with vitamins and minerals that will sustain you throughout the day instead of the fatty, sugary processed foods that may taste good, but leave you with no energy.
6. Your Thyroid
Your thyroid is a gland that makes the hormones that help to regulate your metabolism. In a condition called hypothyroidism, you experience a deficiency of thyroid hormone that leaves you fatigued, sluggish and depressed. The condition has other symptoms including weight gain, increased sensitivity to cold, pale dry skin, constipation, and brittle nails and hair.
Solution: If these symptoms apply to you, see your doctor and get your thyroid levels checked. Hypothyroidism is treatable.
