People who suffer from it do not simulate the disease. Most often, the blues overcome in late autumn, and with renewed vigor rolls in in winter - usually after the New Year holidays.

And this process is understandable. Lack of sunlight in the cold season of the year affects biological processes in the body. Thus, the production of a greater amount of the hormone melatonin provokes the desire to sleep as long as possible.

As a result, a person has difficulty forcing himself to get up in the morning, and then feels sleepy for half a day. A good way to prevent this condition is a morning trip to the gym (or at least a little exercise after waking up). Moderate physical activity in the evening also helps to improve sleep. Doctors recommend devoting at least 150 minutes a week to sports in frosty weather.

Undoubtedly, the diet is also important. Experts advise not to reach for a cup of coffee first thing in the morning, but to replenish energy reserves with carbohydrates. For example, oatmeal. Food with omega-3 fatty acids is ideal for lunch — fish, vegetable salad with vegetable oil dressing.
